AWS EC2

EC2 Types

  • On Demand - pay fixed rate by hour (or second) with no commitment
  • Reserved - provides capacity reservation with significant discount on hourly charge - 1 Year or 3 Year terms
  • Spot - enables you to bid whatever price you want for instance capacity, providing for even greater savings if your applications have flexibile start and end times
  • Dedicated Hosts - physical EC2 server dedicated for your use. Can help reduce costs by allowing you to use existing server-bound software licenses

On Spot Instances:

If they are terminated by Amazon EC2, you will not be charged for a partial hour of usage. However, if you terminate the instance yourself, you will be charged forthe complete hour in which the instance ran.
