This post should be called “Deploying while maintaining HA” or something. I thought of some questions: How is the dev/test env kept up to date for integration/canary tests? When a new app/service is pushed to production does its build/image (AMI?) become the new dev/test env base image for everyone? Do engineers decide which metrics are tracked by Kayenta? Does ops? How does this come together? What about post deployment service monitoring / alerting? When is the dev team off the pager hook? Do you assume that a successful deployment in us-west means it will be successful in us-east or is there an [integration] test done per region? Just curious.
