- Temporal's official deployment guides primarily focus on Kubernetes, which can be complex and costly for some teams.
- This guide presents an alternative using AWS ECS with Terraform, reducing infrastructure costs by ~70% while maintaining reliability.
- ECS offers two deployment options: ECS on EC2 (self-managed instances) and ECS on Fargate (serverless, AWS-managed infrastructure).
- The setup includes auto-scaling Temporal workers on ECS, Terraform-managed infrastructure, and optional CI/CD via GitHub Actions.
- Key components include VPC for networking, ECR for Docker images, Secrets Manager for secure credentials, and CloudWatch for monitoring.
- The architecture ensures workers run in private subnets, securely connecting to Temporal Cloud or self-hosted servers via NAT Gateway.
- Steps include storing Temporal secrets in AWS Secrets Manager, setting up Terraform infrastructure, and pushing container images to ECR.
- Optional GitHub Actions configuration automates builds and deployments, enhancing CI/CD workflows.
- Scaling is managed through CloudWatch alarms and auto-scaling policies, optimizing performance and cost.
- The guide concludes with instructions for destroying the infrastructure to avoid unnecessary costs.
