Before this, all companies had to install and keep the needed infrastructure (Servers, Storages, Hardware, Virtualizers, …) locally. With this technology, they can have the infrastructure somewhere else and just use it whenever it’s needed. We should also mention that some companies still keep the infrastructure locally for different reasons.
Why use IaaS?
As your company grows, you are going to need a more complicated and more expensive infrastructure. IaaS can help you stop worrying about this matter and only focus on your company’s goals. This is exactly what Cloud is for! Cloud services were created to reduce the costs and worries of providing infrastructure.
Another benefit of using IaaS is the security of it. A company’s data is one of its most valuable possessions. This is why we should be really careful about our data security. IaaS providers, keep the Hardware in a suitable place that can keep the hardware physically secured. Also, since this service is cloud-based (which already has all the basic security-related factors), your data can be more secured this way.
The third reason for using this service is the cost. The cost of installing and securing the needed infrastructure of a company locally is much higher than using Infrastructure as a Service. Third-party companies provide a reliable and powerful infrastructure and you can just pay for what you are using.
Just like any other service, Using IaaS is not all pros either. Using IaaS means not having full control over your infrastructure. So, if you need full control and access, this might not be for you. Also, for some very large companies, it might be more beneficial to make the investment and have the infrastructure to themselves.
