Summary:

This is the first major release of the ec2-instance-selector tool.

ec2-instance-selector is a CLI tool and go library which recommends instance types based on resource criteria like vcpus and memory.

Why did we build this?

There are over 270 different instance types available on EC2 which can make the process of selecting appropriate instance types difficult. Instance Selector helps you select compatible instance types for your application to run on. The command line interface can be passed resource criteria like vcpus, memory, network performance, and much more and then return the available, matching instance types.

If you are using spot instances to save on costs, it is a best practice to use multiple instances types within your auto-scaling group (ASG) to ensure your application doesn't experience downtime due to one instance type being interrupted. Instance Selector will help to find a set of instance types that your application can run on.

Instance Selector can also be consumed as a go library for direct integration into your go code.

Major Features

• Filter AWS Instance Types using declarative resource criteria like vcpus, memory, network performance, and much more!
