A computer which adjusts its parameters to the user’s needs. Indestructible, failsafe, immune to data theft? Thanks to cloud computing technology what a few years back was just a vision of inspired scientists is now becoming reality in front of our eyes.

It is hardly possible to imagine a company that operates without computers. Purchase of company hardware and software can be quite challenging. There are many aspects one should consider. You not only wonder whether to choose a PC or a notebook with certain parameters or capacity, but you also have to decide on the software. A newly hired employee must be given a computer with the software he would need in his job. The employer must provide all staff with appropriate software from the legal source and has to remember to renew the license or purchase a new version of the application. Computers get old quickly. It may turn out that the computing power of the hardware bought a few years ago may not handle the latest version of the software. That is why, companies are forced to invest their capital in new equipment.


Isn’t it a headache? Do you think there might be a simple solution to this problem? Of course, there is! We no longer have to be concerned about buying the best, the latest and the most efficient equipment! We no longer have to constantly worry whether our budget can handle the costs of providing new employees with suitable software. It’s a thing of the past! It’s time to move your computer into the cloud.


How does cloud computing work and what are the benefits? Instead of installing a whole bunch of applications and constant updates we may install just one. Only once. How is it possible? This application is a portal to the server where you can find the operating system along with all of the software your employee may need. The external serves ensure that the apps work properly – you do not worry about that. The server may include any software – from a simple email app to a complex one which requires high processing speed and a high quality processor. Software performance in no way depends on the equipment. All operations are conducted in the cloud. The memory and processing speed adjust to the user’s needs at a given moment. Don’t you think the work on the computer in the 21st century should look like that?

Many people have already used the cloud service, but maybe they have not been aware of this fact. They may have used e.g. Internet office apps, bookkeeping online or virtual platforms that store files. An example of a popular cloud service is also hosting. While using those tools hardly anyone wonders about their names and so you may not have been aware that these apps operate and are available thanks to cloud computing.


How is it possible that a cloud computer can do so much? In other words: What does cloud computing architecture look like?


Just like any other application or an Internet website. The components typically consist of a front end platform and back end platform. A front end platform is what a user sees, that is a device (a computer, tablet, smartphone) or an app with which you connect to your computer in the cloud. The interface of such app may be various – sometimes it uses popular browsers like Google Chrome or Firefox, or it is dedicated software which is a portal to your data stored in the cloud.


A back end platform consists of a network of spread computers and servers that make up a „cloud” of your computer. These components are responsible for system administration, monitoring of movement and requests sent by the client’s application. These processes are controlled with protocols and managed via an application (middleware) which provides communication between different active apps and systems. Typically, every kind of app has its dedicated server.

The systems of cloud computers require much more space to store data than computers running in a local environment. That is why, cloud computing technology creates data backups and stores the information on separate devices. Data backups spread results in redundant components in place to maintain the server and Internet availability which translates into constant availability of the service and disc space i.e. data safety and integrity.


Now, you basically know how cloud computing works. But why would you like to choose this service and give up your traditional computer? Here is the list of cloud computing biggest advantages:

    1. A computer in the cloud is safer:
      The safety of the data is not dependent on the performance of your equipment. Failure or theft do not result in your data loss. The user may simply use a different device and keep on working.


    1. Thanks to cloud computing you can work remotely without limits:
      The data that are stored on a virtual disc can be read on any device like a notebook, tablet or smartphone anytime anywhere. For example, you can start your project at home on your desktop computer and carry on while traveling using your tablet.


    1. Thanks to cloud computing you can increase the power and efficiency without the need to buy need equipment:
      The parameters of your cloud computer adjust to the user’s needs. Thus, adding memory, disc space or improving processor performance, which up to now have required additional hardware or even equipment replacement, can be performed using only appropriate configuration options. As a result you may conduct advanced operations which require increased computing power even on old equipment or devices that are not intended for such operations e.g. tablets.


    1. Thanks to cloud computing your company costs are lower:
      A computer in the cloud has smaller equipment requirements than a device that uses a local disc because the computing power is moved to external servers. That is why, you don’t have to update your software all the time or buy new hardware. You cut spending on the equipment but also on employees as you don’t have to take on the staff whose job is equipment maintenance or software installation.


  1. Cloud computing can easily adjust to your employees’ needs:
    Companies often need varied and specialized software matching its profile. Thanks to cloud computing companies have access to almost unlimited sets of apps. What is more, you don’t have to buy a license for each employee separately. Instead, you only have to pay a monthly subscription to your cloud computing service provider.
    Cloud computing used to be of interest only to advanced IT specialists, scientists and some technology journalists. Now, cloud computing is everyday life. The study conducted for VMware in a few countries says that 60 per cent of European companies have already moved some of their IT infrastructure into the cloud. Don’t be left behind – join them. Future lies with cloud computing!
