Answer 1

You can change your EC2 instance type at anytime. The process is

• stop your EC2 instance type
• change the instance type
• start the EC2 instance

You can stop / start and change instance type in the console, CLI or using AWS' API.

Details are here https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-resize.html

There are a couple of compatibility rules to follow (you can not change instance type from 32bits CPU to 64bits CPU for example). Rules are in the doc.

Answer 2

In aws you can change the CPU power of your instance by changing the instance type[1], depending on the instance type you choose, you will be able to Increase or decrease the number of CPU cores of your CPU.

In order to compare between instance types available on aws view : https://aws.amazon.com/ec2/instance-types/ To change your instance type follow the steps in this guide : https://aws.amazon.com/premiumsupport/knowledge-center/resize-instance/

Hopefully this answers your question.
