DevOps Done Right - Room Key's Datomic Deployment in AWS
summary
RoomKey runs Datomic on AWS with peers behind an ELB and transactors in Auto Scaling groups for HA, moving from Datomic’s helper scripts and Elastic Beanstalk to a single unified CloudFormation template (≈1,000 lines) that defines IAM, security groups, CloudWatch alarms and launch configs in source control. Non‑prod deploys use CFN update policies to replace instances; production deploys spin up a new stack with manual zero-downtime transactor failover and DNS cutover. Backups run continuously to S3 from a t1.micro backup host. Continuous Jenkins deploy to staging; requires Datomic Pro.
