Introduction to Cloud Computing

What is cloud computing? How cloud computing works? What are the pros and cons of Cloud Computing? So, let’s learn about all these things in our article. Cloud computing is the storing of data and applications on remote servers and accessing them via the internet rather than saving or installing them on your personal or office computer. The term cloud is used because data and applications are stored on a cloud or collection of web servers and computers owned by a third party somewhere else.

The cloud can be accessed via the cloud computing systems interface software that can be as simple as using a web-based service which hosts all the applications and files that you would need for your job or personal life. The cloud is being used not only to store data but also as an inexpensive, efficient and flexible alternative for purchasing, running and maintaining in-house computing equipment and software. Not only that, the cloud gives you the ability to work anywhere at any time because your information is always at your fingertips. One example of cloud computing is an online email account. You log into a web email account remotely through a browser but the storage for your account doesn’t exist on your computer. It belongs in the email providers cloud. Now, since we understand what is cloud computing system, let us know how our data is stored in cloud computing system.

The cloud computing architecture is comprised of two parts, i.e.  the front end and the back end which are connected by the Internet. The front end represents the computer that you as a client sees this side requires you to access the cloud computing system gaining access can be simple as using an internet browser or more complex by using a unique interface software which lets you access the cloud. The back end of a cloud computing system is comprised of the computers, servers and data storage systems which store all your files and information. This is the part that does all the work. There is a central server that administers the system monitoring traffic and client demands to ensure everything runs smoothly. In addition, this central server follows a set of rules known as protocols. The central server also uses software called middleware that allows the network computers to communicate with each other naturally. Cloud computing companies build a redundancy where they save multiple backup copies of your work in case of problems. However, the more clients have the more storage space they need. So, cloud computing companies require atleast twice the number of storage devices to store all their client’s information. But, why choose cloud computing as a viable option for data storage? Because cloud computing applications are limitless. First using cloud computing allows you to access your applications and data from anywhere so long as you can link with the cloud through the internet. None of your data would be confined to a single hard drive or location. Second, with the movement of your files to the web, you no longer have to pay for expensive high memory computers. You simply need a device that is powerful enough to run the middleware needed to connect to the cloud system.

Third, in a company-wide setting when you use the cloud your employer will not need to buy software or software licenses for every employee. Instead they will pay a fee to a cloud computing company to let all their employees access a suite of software online for servers and digital storage takes up physical space which you may have to rent cloud computing companies store your data on their hardware. So, no physical space is needed at the front end. If streamlining the software and hardware will reduce IT problems and costs finally the cloud computing systems, back-end is a network of computers you may be able to take advantage of the networks combined processing power to speed up operations. However even with all these benefits there are still potential problems. The two biggest concerns are security and privacy. You are handing your important data over to another company to watch not only that if you have the ability to log into your files and applications from anywhere. It’s possible that your privacy could be compromised once the data leaves your hands. Websites and cloud computing services can get hacked but there’s still hope that cloud computing companies live and die by their reputations and reliability. Therefore, they do everything possible to secure your files. But you also need to protect yourself from authentication techniques like user names and difficult passwords.

Don’t reuse or share your passwords on different websites and backup files either on a different cloud service or a hard drive just in case something happens there are also authorization practices where you list the people who are authorized to access certain information stored on the cloud system. For example, an employee might only be able to use certain applications stored on the cloud, which are relevant to their work. One additional concern is the effect cloud computing will have on the IT industry. Cloud computing can streamline computer systems reducing maintenance and repair. Therefore, all the work of IT will move to the backend of the system. You should also consider usage fees and with caps the infrastructure of cloud computing is very expensive. So, companies begin to charge you fees monthly or annually. When you want to store more than a few gigabytes of data you can easily hit your limit right in the middle of transferring the hundred or so pictures you took of your children, pets and meals. That week of course, the error message saying you have run out of space is likely to be accompanied by instructions on how you can purchase more in addition to Internet service providers may implement bandwidth caps which limit the amount of data you are allowed to transfer over their network each month when you go over the limit providers will begin to charge you fees, slow down your connection or cut off your service.

This could most certainly put a damper on your cloud upload and retrieval capability. In summary, cloud computing is about storing your data or files on remote servers instead of on your computers or other devices. This information can be accessed using the internet with any device anywhere in the world. So, as long as the device can support the cloud computing system, the cloud computing system is made up of a front end which is the client side and a back end which is the collection of servers and computers owned by a third party who stores your data in a central server which is part of the backend follows protocols and uses middleware to communicate between networked computers. Finally, although cloud computing reduces IT cost, it increases processing power and allows you to access your files anywhere using a moderately priced device, security, privacy, usage, fees and bandwidth caps are still issues that need to be addressed. We are on the brink of a revolution cloud computing which is everywhere with tools like Google Drive replacing Microsoft Office, banking websites replacing branch offices at Dropbox storing all our data and files.
