Some Important AWS Services

When I first heard about AWS, I thought it provides only the OS infrastructure for your application, Which means the AWS creates a virtual machine on the cloud based on my request also provides complete access to the VM. So that the VM is completely yours you can do whatever in this machine, like application server setup, database installation, setup third party tools…etc. You can treat that machine as your local system but the hardware is placed under AWS infrastructure. But later I realize that AWS is not just a service that provides the VM instance, it contains a lot of services. AWS services can be categorized into Infrastructure as a service, Platform as a service and Software as a service. Here in this article, we are talking about the different services provides by AWS.

The above screenshot explains the difference between Infrastructure as a Service(IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

Infrastructure as a Service(IaaS): This provides virtualized computing resources over the internet. The AWS services such as Amazon EC2, VPC, Gateways, load balancing…etc are comes under IaaS. The advantage of moving the on-premise data center to a cloud-like AWS or Azure or Google cloud is you can save a good amount of money, Can completely avoid the data centre maintenance cost, the cloud systems are highly flexible and scalable.
