Who is using PaaS in the Cloud and why are they using it?

The idea behind PaaS is to make a virtual computer available in the cloud on the Internet. Therefore, everything goes, with all the advantages and risks that come with it. So, who is PaaS for and why do they need it?

When talking about the Cloud, PaaS stands for Platform as a Service. This means that instead of using software installed in the cloud as a service, which is known as SaaS (Software as a Service), computers are used directly. This is one way of installing what you want as if you were borrowing a computer equipped with Windows Server, Linux, etc. with all the benefits of the Cloud. Under this principle, the users of these machines are all the companies which are able to manage the administration of their own server for their own needs.

However, it is useless to try using these services if you can’t count on a good server administrator, whether it be internally or externally. Strictly speaking, the use of this computer in the Cloud, it’s the only thing you can use internally on a server, and it’s the only thing you would use to access the Cloud for many reasons, one of which is quite simple: using the services of a software package that you cannot find in SaaS utilities. In regards to the advantages of PaaS, you benefit from acquisition costs, maintenance costs, energy, telecom costs, etc.

Operational functions

When we think of computers in the cloud we think of with virtual computers whose virtual power and equipment are adaptable to needs. For example, on the Windows Azure platform, you choose the processor power, memory, hard drive, etc. This is the main benefit of this system as there is no need to buy a server that will depreciate over several years and will already be obsolete after only one or two years. The second benefit of this type of platform is security. It’s a given fact that you equip a machine to suit your needs, you install the software services that you want, your work tools and the range of access guarding. Almost everything depends on you and your organisation. Depending on the platforms, you still have secure access to the administration of the machine, more or less, so that you can make improvements: it is your machine after all. However, it’s worth noting that on some platforms, access is highly protected: logins and passwords are such that the only risk would actually lie in a flaw found in the system administration of the virtual machines.

What about the data?

In regards to the data, once again, the benefits of PaaS is being able to benefit from it with your own computer. You can install the software there to back up your data which you want to keep. You are not obliged to keep the backup on the same machine which you are using. It’s even advised that you don’t keep it there. Why not use the utilities of a SaaS backup platform? It’s easy to understand that PaaS is indeed a Cloud service type that overcomes the traditional issues associated with infrastructure and machine limitations. PaaS is combined with existing infrastructures, if the internet connection element has been designed accordingly.
