On-Demand Pay for compute capacity by the second or hour with no long-term commitments For spiky workloads or to define needs initially AWS EC2 Consumption Models Reserved Significant discount compared to On-Demand instance pricing Steady state applications or predictable usage, databases Spot Spare EC2 capacity for up to 90% off the On-Demand price. For fault tolerant, instance flexible or time-insensitive workloads

The Very Simple Rules of Spot Instances The price changes infrequently based on supply and demand of spare capacity Just request capacity and pay the current rate. When we need the capacity back you’ll get a 2 minute warning

13. © 2018, Amazon Web Services, Inc. or its Affiliates. All rights reserved. New Pricing Model - summary • Reliable Spot costs – prices change less frequently • No “bidding” required – if you choose to bid you’re setting a “Maximum price” • Price no longer changes to reclaim instances

14. © 2018, Amazon Web Services, Inc. or its Affiliates. All rights reserved. Handling interruptions Spot is optimized for stateless, fault-tolerant, or flexible workloads. Any application that can can have part or all of the work, paused and resumed or restarted, can use Spot. Minimal interruptions Over 95% of the instances were not interrupted in the last 3 months Check for 2-minute instance termination notice via instance metadata or CloudWatch metrics and automate by: ☑ Checkpointing ☑ Draining from ELB ☑ Using stop-start and hibernate to restart faster The work you are doing to make your applications fault-tolerant also benefits Spot
