We’re publishing a GitHub project to help manage services on AWS on-demand and spot instances. Our demo goals include spot instance launch on request or on schedule and managing uptime of on-demand instances using hibernate behavior to minimize compute costs. Instances would be launched or revived on demand, for example when a client tries to connect to the server’s inbound TCP port, or on schedule to avoid any latency.
There will be a Cloud Savings project page here linked at right, but most of the good stuff will be on GitHub. Check out our progress at https://github.com/bryanherger/aws-ec2-service-proxy
