Understanding EC2 and Its Evolution

To understand why EC2 is so essential for the AWS EC2 instance types, it’s helpful to take a step back and look at the history of virtualization. Virtualization is creating a virtual version of something, such as a server or operating system, using the software.

In the early days of virtualization, it was mainly used for testing and development. Developers could create virtual environments to test their code and configurations without physical hardware.

But as virtualization technology improved, it became possible to use it for production workloads. Virtualization allowed businesses to run multiple applications and OS on a single physical server, a significant cost saving compared to running each application on a separate server.

This is where EC2 comes in. EC2 is a web service that provides resizable computing capacity in the cloud. This means you can easily spin up new virtual servers (called instances or, in this case, EC2 instances) to run your applications and then shut them down when you no longer need them. EC2 makes it easy to scale your applications up or down based on demand, essential for ensuring optimal performance and cost-effectiveness.
