title: Increase vCPUS/RAM if needed
body: <p>I have create a AWS EC2 instance to run a computation routine that works for most cases, however every now and then I get an user that needs to run a computation routine that crashes my program due to lack of RAM.</p>
  <p>Is it possible to scale the EC2 instance's RAM and or vCPUs if required or if certain threshold (say when 80% of RAM is used) is reached. What I'm trying to avoid is keeping and unnecessary large instance and only scale resources when needed.</p>
