This is an introductory article that introduces AWS.
AWS - Amazon Web Services
Before we get into AWS, we need to know a thing related to cloud computing.
If you are familiar with cloud computing, then you may know cloud service models.
There are three types of cloud service models:1. IaaS (Infrastructure as a Service)2. PaaS (Platform as a Service)3. SaaS (Software as a Service)
Now, we know the types of models in cloud computing. Then let's begin with AWS.
AWS is the most well-known cloud provider in the world. Its competitors are Microsoft Azure, GCP (Google Cloud Platform), Alibaba cloud, and so on.
AWS is an Infrastructure as a Service + Shared Responsibility Model.
