Elastic Compute Cloud (EC2)

This is where AWS began. Amazon EC2 is a foundational service within AWS that provides resizable compute capacity in the cloud. EC2 instances are virtual servers that allow you to run applications and workloads, ranging from simple to complex, with flexibility and scalability. In this chapter, you will explore the key aspects of EC2 instances, covering various topics that are relevant to the AWS Certified Solutions Architect - Associate (SAA-C03) exam.

When choosing an EC2 instance, you will need to decide between different instance sizes, operating systems, storage persistence, CPU scaling abilities, as well as cost optimizations. It is a lot to consider. You can start by looking at the different types of EC2 instances you can provision and when you should use them.

Understanding EC2 Instance Types

EC2 instance types are optimized to meet specific performance, storage, and networking requirements. These instance types are grouped into families...
