Like anyone, you may want to take advantage of cloud computing services, but you do not know what is the difference between them and how you will choose the type of service that suits your needs, so here we will provide a detailed and full explanation of the IaaS infrastructure as a service.

IaaS : Infrastructure as a service

Infrastructure as a service means that the cloud service provider will provide you with the infrastructure from cloud computing resources within a virtual environment represented by the cloud via the Internet.
In simpler terms, it is like buying a computer to work on, with specifications that you specify and are able to increase and decrease according to your needs, and this is what distinguishes cloud computing services, so if you buy a computer from an electronics store, you will choose the specifications of the processor, memory and the size of the hard disk, so you specify, for example, that you want 5 processors Of a certain type, and maybe you will choose a memory space of 4 GB, and then you will choose the size of the hard disk of 500 GB, and other specifications that interest you in your work.

Then you will start using your new device, add the operating system you want, add the software and applications you need, and start working on it.

With the passage of time, the device’s memory will begin to fill up, and the pressure will increase on the limited processors you have, then you may have to change your old device with a new device with larger specifications. Hey, you will leave the old and its high cost and go to buy a new device at a new cost, you are heading for more expenses and this is impractical, especially if you are a company owner and you will change 10 devices instead of one device!
In addition, you will strive to transfer the files that you want to obtain to your new device, and after a period of time the storage space will be filled and you will need to update the device to higher specifications! Will it continue like this?

Cloud computing is a solution

Cloud computing gives you a simple and convenient solution for all your needs, which is infrastructure as a service ( IaaS ), all you have to do is choose a cloud service provider and choose the specifications of the computer you want to work on, you will buy an infrastructure, but with the specifications that fit your needs, you will choose processors according to the speed you want and choose memory And storage space according to the size of your business and your data.

The infrastructure as a service provides virtual server space, communications network, IP addresses, and bandwidth.

your role in IaaS

It remains for you to download the operating system, programs, and applications that you want to work on and start working on your virtual machine with ideal specifications that meet your needs.

pay as you go

Suppose your business has doubled and your storage capacity is full of resources that you purchased from the cloud, what will you do now? Simply, you will go online to the service provider’s website and with one click to request an increase in the number of processors or storage space and memory according to your needs. So, the difference between them you did not give up the previous specifications, as happened when you bought a traditional computer, but rather added an addition to them, which means that you will pay for that increase only.

Also, suppose that one day your work pressure decreases and you find that you have a lot of storage space that you do not need, but you are still paying money for your reservation, what will you do? The cloud computing service allows you to reduce the equipment that you have purchased also according to your needs, and with the click of a button, you release it and thus reduce useless expenses.

IaaS : no need for maintenance

One of the most important things that IaaS gives you is maintenance without charge, you will not care about maintenance matters or cooling your devices that you have booked from the cloud, or the amount of energy spent on them, you only pay for the resources that you have booked. As for their maintenance, operation, etc., it is the responsibility of the cloud service provider.
