Create an Virtual Window Server for Development on AWS
Steps to Create and Connect to a Windows Virtual Machine on AWS
- Log on to your AWS Console as an IAM user who has permission to create EC2 instances
- Create an EC2 instance and make sure to create KeyPair
- Make sure you check the individual price when selecting the instance type
- Open the new EC2 instance and click Connect to view the instruction on how to connect
- Download the RDP file
- Find the Password by decrypting the public key (the pem file from the Create EC2 step)
- Download Windows RDP (Remote Desktop)
- Create a new connection profile using the RDP file, then connect to the new instance using the decrypted password
- After development, stop (not terminate) the instance so you are not being charged for the Compute price.
- If you are done with this instance and no longer need it, you can terminate it so that you don’t need to pay for the storage price.
