Disclaimer

• Spot instance interruptions notice happens 2 minutes prior the activity. So make sure your service does not contain long running process and can be exited safely during the lambda execution.
• For critical production workloads that cannot bear simultaneous spot interruptions, please use mixed instance distribution to ensure there is an on-demand instance for back-up e.g: 50% spot and 50% on demand.
