MongoDB in AWS (MongoDB as a DBaaS)
summary
Automated DBaaS that builds configurable MongoDB clusters on AWS: CloudFormation templates plus Lambda calculate instance counts and preassign member IDs, Auto Scaling Groups launch instances and handle replacement only, DynamoDB stores instance metadata and build stages, EBS volumes and ENIs are attached and reused if replacement is in same AZ, Consul provides service discovery, KMS/S3/SNS/SQS handle secrets, backups use EBS snapshots, cross‑region uses two stacks reading the primary DynamoDB; mid‑build failures cause the CloudFormation stack to fail and require restart.
