Think of EC2 as a virtual computer that you can use for whatever you like, such web hosting server

Amazon EC2, good for any type of "processing" activity.

All you need to know about auto scaling

  • basic introduction to auto scaling
    . Auto scaling group (min/max, meet desired capacity, balanced across AZs)
    . Launch configurations(EC2 instrance type/size, Amazon Machine Image(AMI), security groups, IAM, user data)
    . Bootstrapping(installation and setup needs to be fully automated)
    . Termination policies: Longest running, Oldest launch configuration, closest to full billing hour(rebalancing of capacity across AZs take precedence)
    . Scaling plans: default, manual scaling, scheduled scaling
  • scaling policies
    . set fixed capacity
    . fixed number of instances
    . percentage of existing instances
    . scaling on a schedule
    . Dynamic scaling policies
    . step scaling policies are evaluated continuously.
  • Benefit of auto scaling
    . automatically adapt capacity to demand
    . Availability & Reliability
  • Controlling launch and termination of EC2 instances
