10,000 Free Game Apps At Your Finger Tips

Amazon launches Underground to promote complimentary apps and games. It also means that the “Free App of the Day” program has also ended. The Free App of the Day, inning accordance with Gadget spot, is most likely related to the launch of Underground. With an entire section dedicated to promoting entirely complimentary apps, it appears like Amazon has discovered an excellent method to drop its every day totally free app program.

Amazon introduced a new app for shopping merely for Android users called Underground. It is a compilation all of the exclusively free apps provided by the Appstore. Underground gathers and showcase apps and video games that are 100% complimentary without any unknown fees like in-app purchases. Amazon Underground offers admittance to more than 10,000 apps. But unless you are among the hundreds of people still using the Fire Phone (Amazon’s Smart Phone last 2014), it’s still a pain for many people to set up any Android users will face difficult task is setting up the App Store. To prevent users from being charged by the in-app firms and the routinely level up changing fees; Amazon has formed a negotiation with the app developers where Amazon pays them on a per-minute played basis. A brilliant idea that leads gamers to enjoy free Gaming Online. Sample of Free Apps are Angry Birds, Star Wars, Rebels Recon Missions and are now totally free.

Amazon’s Underground Victory hangs on the Video Quality of the complimentary Gaming APP it provides. It does attract millions of app users, but this notion is NOT entirely true. The others may see the situation in this regard, but the ACCESSIBILITY FEATURE is the main factor to the end consumers. Due to Google Play Store rules, you cannot download Amazon Underground through the app shop, so you must go to Amazon’s website if you desire the new app, and jump through a few hoops to obtain it set up on your Android gadget. This reason has been the biggest limitation (besides an absence of content in comparison to Google Play) to success for Amazon’s Appstore. Few people don’t want to handle the hassle of changing security settings especially APK documents set up just to access the generic content that is already in the Google Play App Store. Whether Amazon Underground can change that mindset will largely depend on the quality of content it offers for free in its Appstore.

While playing with the Amazon Underground is the best option in your computer or smartphones, we will see more of how the game in your living room by Amazon TV looks like in the next news.

Software Tv Online For Computers

Years ago, software TV online downloads made their way to computers to watch all kinds of television programs online. Many 3rd party, free and cheap pay-to-use services sprung up over the Internet later on and appealed to a small market (individuals) worldwide. Most TV software downloads were only compatible to Windows computers, and still are today, leaving many Mac and Linux computer users left out.

Nowadays, anyone can go online and do a search for free TV software. Many download websites will be listed but many of these freeware products are not safe to use. Many are not supported very well, if at all. Many are not compatible with new computers and operating systems. And many of them cause computer crashes, freezes, viruses, malware, etc.

What has become safer to use and more entertaining are 3rd party web-based TV/VOD services that are low-cost. Unlike free or low-cost TV software, Internet based TV/VOD services offer better entertainment. Of course, there are good some good freeware out there and pay-to-use software but web-based has more of an upside.

However, there are some gray areas to consider. Web-based TV/VOD services bring together live TV and/or on-demand TV at your fingertips. You can access all the content from one location and use any streaming device that has a web browser. An individual can watch live premium TV channels from popular networks with live sports, movies, TV shows, and news broadcasts. Or watch on-demand movies and TV shows. Some web-based services offer both live and on-demand TV.

If saving cost comes is at the top of your list, then paying as little as $40 one-time or $30 annual fee is a lot of savings compared to cable/satellite TV. One could use the savings to invest in a faster Internet connection to avoid buffering and playback issues. A fast Internet connection will allow connecting more steaming devices to ones wifi networks, without a major decrease in Internet connection speed.

A faster Internet connection of 25 Mbps or higher will also help when more people are online watching the same streaming content. What this boils down to is avoiding buffering and playback issues. The best streaming device to use, believe it or not, is a computer. But any Internet-connected devices with a web browser can also access a web-based TV/VOD website — this includes Netflix, Hulu Plus, etc.

Software TV online downloads have limited content to watch. Although there could be 1000s of channels, many dont work/play. Overall, the entertainment isnt that good. Unless you live outside the US or living off a very tight budget, free software may be the only way to go. But paying $30 or $40 would be the ideal thing to do, if wanting the ability to watch any live sporting event worldwide instantly. Or want to watch entertaining old/recent movie and TV shows.

If getting access to many news broadcasts are of any interest to you, then a web-based TV services would be better to use. Less problems occur with these services. You download nothing, so nothing eats up hard drive space. Theres no virus to be concerned about or computer crashes, unlike those old un-supported TV software downloads.

Web-based TV services work well when connecting a computer to TV. You simply log into the web-based TV members area, point and click to a channel link name, and start watching the program. The picture quality will either be SD (Standard Definition 720p) or HD (High Definition 1080p). With a fast Internet connection speed (25 Mbps or higher) there shouldnt be a problem watching any streaming content online.

With a wifi network, any steaming device can be connected. An Internet-connected computer can be connected to a smart TV wirelessly or HDMI cable (or compatible cable). A computer can be connected to any TV or HDTV via HDMI cable (or compatible cable). And the same for any smartphone, though some of them may not connect wirelessly without the use of an app, if at all.

TV software doesnt offer the best option to watch TV online. A good web-based TV/VOD service can offer the next best thing to cable and satellite TV.

The Advantages Of Repairing Your Cell Phone Over Replacing It With A New One

Unlike in past where cell phones were primarily used for communication, today’s phones have more functionality. More and more innovations are being discovered everyday creating the possibility that cell phones will one day replace personal computers. Smartphone brands such as iPhone, Blackberry, Samsung are leading the pack in this new age.

With many cell phones in the market, there has been a rise in cases of phones getting damaged. Consequently, there are plenty of cell mobile phone repair shops available to cater to this need. But many people continue to overlook such services in favor of replacing their damaged gadgets with new ones. The following article highlights some of the reasons why repairing a cell phone is better than replacing it with a new one.

Obviously, the first benefit of repairing a cell phone over a new replacement is cost. Most cell phone repairs don’t cost a fortune unlike investing in a new phone that can cause a serious dent to your pocket. On average, most cell phone repairs cost less that $100, while some new high end phones can cost up to $1000. If you are short on budget and you cell phone malfunctions, then your best bet should be to take it to a phone repair clinic like Rapifix Montreal. Most phone repair clinics have experienced technicians who can handle just about type of problem. If you donât have the required budget to buy a state of the art phone, don’t sweat; a good phone repair service can restore your phone back to its former capacity.

Data loss

If you opt to buy a new phone rather than repair your existing one, you could lose all the data stored in your old phone. On the other hand, taking your phone to phone repair shop has major advantages in that your data wonât be lost. For instance, throwing your old phone to the trash bin can cause you to lose vital data such as your friends contact list that youâve obviously invested lots of time to create. To prevent incidences of data loss, repairing your cell phone is therefore a better option.

Repairing phones instead of buying one each time there is a little damage is actually a good thing for the environment. If more phones are repaired instead of being trashed for new ones, then the environment would be much cleaner. However, that is not the case as many people purchase new phones everyday. Phones can cause radiation besides contributing to global warming. As such, people who are conscious about the environment should repair their phones instead of buying new ones to set a good example for others.

In the end, repairing a phone of buying a new one is a smart choice especially from a financial standpoint. Secondly, repairing phones is beneficial in the sense that you can easily preserve your important data. Thirdly, repairing your phone is good for the well-being of our environment, considering more and more phones will increase radiation and global warming. If you are considering buying a new phone because your old model is damaged, think about the above advantages before making your choice.

The Cyber Threat To Your Website Is Real!

Most companies have a website, all are different but they all have a common goal: that is to promote their businesses.
Most business owners value the benefits of the company website, but unfortunately they do not appreciate the risk they are putting their company under.

A recent report suggests that there were over one million web attacks against people and companies each day in 2015, every attack is a potential threat to a company.

Therefore it is safe to say that major security vulnerabilities in three quarters of popular websites put us all at risk, many business owners are under the impression that keeping to well-known, legitimate and trusted websites will keep them safe from cyber-attacks. Unfortunately this is not true.

Cyber criminals will exploit any area of a trusted website that is vulnerable, to attack users. The major factor in securing any website is to ensure all updates and patches have been performed and kept up to date. Website administrators need to ensure that they are on top of updating patches.

More than three quarters of all websites have unpatched vulnerabilities.

There is another interesting statistic; more that 15% of legitimate and trusted websites have critical vulnerabilities. This is frightening because these exposures allow cyber criminals to infect the site, gain access and manipulate these sites for criminal gain.

These attacks will then infect all users that interact with the infected site, and it becomes a chain of events that multiplies up many times. So from one site infection, it can cause havoc with many thousands.

The cyber criminals will try and manipulate the attack to get maximum exposure. This can take many forms depending on the cyber criminals motivation to infect the sites, but may include locking the system so that any user annoy have access to their data. The cyber criminals may demand that the website owners pay a ransom of some sort so the cyber criminal will then free the site for it to be accessed again. However, this may not be the end of their demands, and further ransom may become apparent at a later date.

The key to protecting companies from cyber threats include some of the following actions. Make sure the web administrator is aggressive in updating and applying any patches released by their internet protection provider. Instruct all users not to open email attachments from any untrusted or unfamiliar source. The business owner needs to ensure that they have a cloud backup strategy that protects them from any such cyber-attack, making sure the data can be restored quickly and efficiently to minimise downtime.

Cyber threats are a massive problem for all concerned, and must be tackled aggressively by the business owners.

Improvements In Data Quality Of Clinical Data Management Systems Brought About By The Use Of Electronic Data Capture Software

Electronic data capture (EDC) makes clinical research better nowadays. Although clinical studies were done centuries before, the first proper clinical study was only performed in the 1700s. While there was no medical data collection done before this time, observations and results were written in paper.

Clinical studies are an important tool for research. They help advance medical knowledge and patient care. Without properly recorded data, the medical community cant develop new drugs and treatment methods.

As a user, you are able to collect important data from clinical studies using various tools offered by EDC systems (Schwartz, 2014). These tools enable you to improve the way you analyze data and report high quality results. It also speeds up your documentation process of clinical studies wherever relevant. Taking advantage of these capabilities in turn, not only results in time savings, but can also positively affect a countrys economy.

In the United States, the National Institutes of Health Director Dr. Francis Collins led the completion of the Human Genome Project to map the human DNA. It was one of the best examples of a clinical trial that had a high return of investment (ROI). From a budget of just $4 billion, it generated an economic growth that translated to $796 billion in its first decade alone.

Data Quality in Clinical Data Management

The advantages brought by EDC makes it imperative for users like you to provide high quality clinical data. The concern however, as raised by Alsumidaie and Andrianov (2015), is the lack of data quality definitions and standards. As a result, data is considered inaccurate (no data integrity) and becomes invalid (no data consistency), thus losing its quality.

Aside from this concern, Alsumidaie and Andrianov (2015) points out the risks of using data wholly recorded on paper. The two cited an example of data being incorrectly recorded and thus misinterpreted.

The Use of EDC Software as eClinical Solutions

While clinical data management standards have to be efficiently defined and managed, clinical trial software such as an EDC system is an important research tool that helps improve data quality.

What Is an EDC?

Electronic Data Capture is a general term used to describe the process of recording clinical trial data in electronic form. Typically, you record data on paper first, transcribe it in an EDC, and then save it as an electronic case report form (eCRF). Check out the video below to learn more:

Before the 1990s, EDC operated as Remote Data Entry (RDE) software. Users were provided with a computer or laptop that had the software in it. Whereas data were forwarded to clinical trial sponsors before, you can now immediately record and check clinical study data. Fortunately, because of usability, cost, and hardware issues caused by RDE, EDC was born.

Features Offered by Clinical Data Solutions

The introduction by the U.S. Food and Drug Administration (FDA) of the Critical Path Initiative (CPI) in March 2004 motivated EDC software developers to add important features in their products (Babre, 2011). Newly developed features you can look forward to include:

– Compliance with regulatory standards

– Prevention of unauthorized access to data

– Appropriate tools based on user role

– Application of electronic signature

– Detection of fraudulent data

While these are special, other common features include:

– eCRF designer, so you can create different kinds of forms that you commonly use across different studies

– Data entry, so you can automatically record data

– Query management, so your EDC can communicate with other clinical trial management software operated by other users

– Data export, so you can extract patient data

Collectively, these features enable EDC systems to provide high quality clinical research data. As a result, more clinical trials are now using EDC as compared to those still using the traditional, paper-based method, which is error-prone and time-consuming (Walther, Hossin, Townend, Abernethy, Parker, & Jeffries, 2011).

Enjoying the Benefits of a Clinical Trial Management System

EDC can help you improve data quality by providing consistency and accuracy.

Data Consistency

Data consistency is the most important part of conducting research. An EDC system with standard data collection tools and forms makes it easier for you to achieve this. A standardized data collection method eliminates user bias and other factors that could complicate results.

Data Accuracy

EDC systems can prevent you from entering inaccurate data by adding user constraints to the forms it provides. This improved data quality gives you cleaner data that has legible entries and automated calculations.

Conclusion

Electronic data capture enables you to improve data quality for your clinical trial record and results (Wilson, 2015). In addition, it provides cleaner data, faster access to results, and more efficient clinical data collection.

A Look At Internet Radio Stations

Following the invention of the internet in the 1970’s and the introduction of the world wide web in 1990, the first internet radio broadcasts came about in the mid 1990’s. Since then the technology has advanced at pace, as has the format of internet radio, and given us the scenario we know today. Throughout the developed world most homes now have direct access to the internet and nearly every member of the population has a computer with internet access, be it desktop, laptop, notebook, tablet or smartphone.

Traditional terrestrial radio stations still pump out their cosy but dull, fully scheduled programs on a regular basis, interrupted regularly for commercial breaks. A lot of these larger corporations also run associated internet radio channels, that are regularly interrupted with commercial breaks. Alongside this, independent internet radio has developed as a force to be reckoned with, having taken its own path.

Internet radio stations make use of highly efficient modern streaming technology to distribute data streams across the entire internet. This content can be accessed by anyone, anywhere in the world as long as they have internet access and a computer or domestic internet radio.

These independent internet radio stations cost very little to set up and run so have grown massively in number until there is currently estimated to be over 20,000 channels available to everyone. As it is often a one man band or small committee who run them, they tend to offer their service free of charge and rely on voluntary donations to keep them going. They are therefore free to set their own parameters for programming and content, hence the extreme range of subject matter and wide spectrum of music genre, sub-genre and even sub-sub-genre to be discovered somewhere amongst them.

There are many ways to find the internet radio station you want. If you have a domestic digital radio such as the one in the video below, it will already be set to such stations as Sirius XM, Live365, Pandora or iHeartRadio. These same stations are easily found when browsing with computer access.

Whether you use a computer for internet access or a domestic internet radio, you have access to thousands more stations than a standard terrestrial radio, enjoyment of your favorite music uninterrupted with commercials, and no fear that the signal strength will diminish with weather conditions or distance from the radio source.

For further information on the availability of domestic internet radio models, please visit http://www.bestinternetradioschoice.com where you will find comment and feature reviews of all the top internet radio models.

Existing Types of Databases

Databases have provided a perfect way of storing large amounts of data for individuals, businesses, and companies. Databases vary in security; some are open access while others have strict security protocols that may even include scans.

Huge volumes of primary data are archived in numerous open-access databases, and with new generation technologies becoming more common in laboratories, large datasets will become even more prevalent. The archiving, curation, analysis and interpretation of all of these data are a challenge. Database development and biocuration are at the forefront of the endeavor to make sense of this mounting deluge of data.

Databases allow quick arrangement and translation of data that may have been a challenge without such systems. The following are the types of databases available on the market;

a.Operational databases:

These databases store data relating to the operations of the enterprise. Generally, such databases are organized on functional lines such as marketing, production, employees, etc.

b.End-User databases:

These databases are shared by users and contain information meant for use by the end-users like managers at different levels. These managers may not be concerned about the individual transactions as found in operational databases.

Rather, they would be more interested in summary information. Although, the operational databases can also generate summary information from the transaction details, they would be quite slow as they are not designed for this purpose.

c.Centralized databases:

These databases store the entire informa¬tion and application programs at a central computing facility. The users at different locations access the central database to make processing. The communication controller sends the transactions to the relevant application programs. These programs pick up the appropriate data from the database for processing the transaction.

For example, Mahanagar Telephone Nigam Limited (MTNL) has a centralized database for registration of applications for new tel¬ephone connections. The data regarding the applicant are received from a local area office of MTNL.

Data validation and verification is carried out by the application programs at the central computer center, and a registration number is allotted by the application pro¬grams located at the central facility. The local area office keeps on recording it and hardly does any processing.

database-155323_1280

d.Distributed databases:

These databases have contributions from the standard databases as well as the data captured from the local operations. The data remains distributed at various sites in the organization. As the sites are linked to each other with the help of communication links, the entire collection of data at all the sites constitutes the logical database of the organization.

These data¬bases reduce the communication requirement by ensuring that the detailed local information remains stored in the local facility. To¬day, the client-server technology is most popular for managing distributed databases. In a client-server environment, DBMS has two components, one interacting with the needs of the user (client) and passing requests to the other component of DBMS.
The other component interacts with the database to meet the information needs of the client. The primary reason for dividing the DBMS into two components is that a part of the job is moved to the user’s PC (client). This makes the simultaneous processing possible on client PC and Server com¬puter system. The server is also able to coordinate the requests from a number of clients at a time.

e.Personal databases:

The personal databases are maintained, gen¬erally, on Personal computers. They contain information that is meant for use only among a limited number of users, generally working in the same department.

These databases are generally subject specific and are user designed. They use simple and less powerful DBMS packages available on PCs. These DBMS packages may not have all the features of relational DBMS but do have simi¬lar features in a limited way.

f.Commercial databases:

The database to which access is provided to users as a commercial venture is called a commercial or external database. These databases contain information that external users would require but by themselves would not be able to afford the main¬taining such huge databases.

These databases are subjected specific and access to these databases is sold as a paid service to its user. There are many commercial database services available, particularly in the area of financial and technical information.

These databases may offer statistics regarding commodity, foreign exchange and stock markets, companies and their performance, importers and their buy¬ing patterns, decided case laws, etc. The access to commercial databases may be given through communication links.

Some of the database service providers also offer databases on CD-ROMs, and the updated versions of the databases are made available periodically. The databases on CD-ROMs have the advantage of reduced cost of communication. However, in applications such as stock market, com¬modity market, and currency market information, this medium is not suitable because information is needed on a ‘real-time’ basis.

What is a Database?

The use of databases is an ingenious way of storage and processing of large amounts of information. Databases are specified according to the client’s needs be it for business or personal use.

Databases often abbreviated DB; a database is basically a collection of information organized in such a way that a computer program can quickly select desired pieces of data. You can think of a database as an electronic filing system.

Traditional databases are organized by fields, records, and files. A field is a single piece of information; a record is one complete set of fields, and a file is a collection of records. For example, a telephone book is analogous to a file. It contains a list of records, each of which consists of three fields: name, address, and phone number.

An alternative concept in database design is known as Hypertext. In a Hypertext database, any object, whether it is a piece of text, a picture, or a film, can be linked to any other object. Hypertext databases are particularly useful for organizing large amounts of disparate information, but they are not designed for numerical analysis.

To access information from a database, you need a database management system (DBMS). This is a collection of programs that enables you to enter, organize, and select data in a database.
Increasingly, the term database is used as shorthand for database management system. There are many different types of DBMSs, ranging from small systems that run on personal computers to huge systems that run on mainframes.

Sourced from: http://www.webopedia.com/TERM/D/database.html

The information in a database is access via a database management system; that are typically an aggregation of programs. The programs arrange, interpret, maintain, and store information; which is the primary goal of databases. The database manager will act as a way of controlling all the processes.

Computer databases typically contain aggregations of data records or files, such as sales transactions, product catalogs and inventories, and customer profiles. Typically, a database manager provides users the capabilities of controlling read/write access, specifying report generation, and analyzing usage. Databases and database managers are prevalent in large mainframe systems but are also present in smaller distributed workstation and mid-range systems such as the AS/400 and on personal computers. SQL (Structured Query Language) is a standard language for making interactive queries from and updating a database such as IBM’s DB2, Microsoft’s SQL Server, and database products from Oracle, Sybase, and Computer Associates.

Sourced from: http://searchsqlserver.techtarget.com/definition/database

Some of the common databases include; Oracle databases, IBM DB2, and Microsoft’s SQL server. The following are the existing sub-classes of databases;

1.General Interest Databases

General interest databases are a great place to begin research or for a general topic. These databases contain the broadest range of materials and include many different subjects and disciplines. Examples of general interest databases include:

  • Academic Search Complete (EBSCO) – Identifies magazine and journals articles in most subject areas including social sciences, humanities, education, computer sciences, engineering, medical sciences, and ethnic studies.
  • Academic OneFile (Infotrac) – This multi-disciplinary database provides access to over 3000 journals, with links to full text for over half of the journals.

2.Discipline-Specific Databases

database-149760_1280

Discipline-based databases are more focused than general interest databases. These databases include materials in several related subject areas. Materials are usually only from professional/trade publications and scholarly/academic journals. If you are having trouble finding information on your topic, in general, interest databases, try a discipline-based database.

  • Ethnic NewsWatch – Identifies full-text access for 200 newspapers and journals of the ethnic, minority, and native press.
  • PAIS (Public Affairs Information Service)– Contains information sources for the government, political science, social science, and related topics.
  • SocINDEX (EBSCO) – Identifies articles in all areas of sociology including anthropology, criminology, ethnic & racial studies, gender studies, politics, religion, rural sociology, social psychology, and urban studies.
  • Sports Discus – Scholarly and popular information on all aspects of sports, exercise, training, etc.

3.Subject-Specific Databases

If you are doing in-depth research on a topic, you will want to use subject-specific databases. These databases usually only contain materials from professional/trade publications and scholarly/academic journals. Below are some examples, but a list of all available subjects can be viewed on the Online Journals and Database’s page.

  • ABI/INFORM – Identifies articles on business, finance, and management topics from regional, U.S. and international publications.
  • CINAHL (EBSCO) – (Cumulative Index to Nursing and Allied Health Literature) – Authoritative coverage of the literature related to nursing and allied health.
  • Historical Abstracts – Scholarly articles on the history of the world from 1450-present.
  • PsycINFO – Identifies articles, books, and dissertations in psychology and related subjects.

What is Cloud Computing?

The world of information technology is ever growing and improving. The latest introduction is the use of cloud computing to store information that can be shared easily. The use of cloud computing has eliminated the need for local servers that can easily be hacked.

Cloud computing is defined as a type of computing that relies on onsharing computing resources rather than having local servers or personal devices to handle applications. Cloud computing is comparable to grid computing, a type of computing where unused processing cycles of all computers in a network are harnessed to solve problems too intensive for any stand-alone machine.

Cloud computing is similar to grid computing where any unused processing cycles are put together to solve a severe problem that cannot utilize a standard machine. Cloud computing uses a non-hard drive technology to store information.

It goes back to the days of flowcharts and presentations that would represent the gigantic server-farm infrastructure of the Internet as nothing but a puffy, white cumulonimbus cloud, accepting connections and doling out information as it floats. What cloud computing is not about is your hard drive. When you store data on or run programs from the hard drive that is called local storage and computing. Everything you need is physically close to you, which means accessing your data is fast and easy, for that one computer, or others on the local network. Working off your hard drive is how the computer industry functioned for decades; some would argue it is still superior to cloud computing, for reasons I will explain shortly.

Cloud computing allows the user to access their information at any location, which makes data access easy and convenient. The only requirement is that cloud computing needs to utilize or, at least, be synchronized via the internet.

For it to be considered “cloud computing,” you need to access your data or your programs over the Internet, or at the very least, have that data synchronized with other information over the Web. In a big business, you may know all there is to know about what is on the other side of the connection; as an individual user, you may never have any idea what kind of massive data processing is happening on the other end. The result is the same: with an online connection; cloud computing can be done anywhere, anytime.

Cloud computing allows the user to have convenience, increased storage, and quick data processing. The basic working of the system is as follows;

The goal of cloud computing is to apply traditional supercomputing, or high-performance computing power, normally used by military and research facilities, to perform tens of trillions of computations per second, in consumer-oriented applications such as financial portfolios, to deliver personalized information, to provide data storage or to power large, immersive online computer games. To do this, cloud computing uses networks of large groups of servers typically

running low-cost consumer PC technology with specialized connections to spread data-processing chores across them. This shared IT infrastructure contains large pools of systems that are linked together. Often, virtualization techniques are used to maximize the power of cloud computing.

Cloud computing utilizes supercomputing or high maintenance computing power that was initially only utilized by the military and research organizations. The following are some of the benefits each user enjoys when they utilize cloud computing;

1.Self-service provisioning: End users can spin up computing resources for almost any type of workload on-demand.

2.Elasticity: Companies can scale up as computing needs increase and then scale down again as demands decrease.

3.Pay per use: Computing resources are measured at a granular level, allowing users to pay only for the resources and workloads they use.

4.Cloud computing services can be private, public or hybrid.

5.It’s virtual

Imagine racks of servers, humming along in a data center. Together, these servers become a massive pool of resources. Divide this “pool” into multiple virtual servers, and you create a “cloud.”

6.It can be secure

For the utmost security, create a private cloud on dedicated hardware. However, always remember to put appropriate security measures in place, no matter which cloud you choose.

7.It’s flexible and scalable

Since virtual servers are not physical, they are super flexible, giving you what you need at the moment. Spin up a server in minutes, and take it down just as easily.

8.It can be affordable

You will get the greatest cost savings in the public cloud, where your virtual servers run on physical servers that you share with other customers.

9.It’s open (or closed)

In the open cloud, you can easily move your cloud around—without being locked into one provider or a closed, proprietary technology.

10.It can be secure and affordable

A hybrid cloud gives you the benefits of both public and private clouds. For example, you can put public-facing components in a public cloud while storing customer-sensitive data in a private cloud.
