How do you deploy your core services?

I use a CI/CD pipeline that starts with source control in GitHub. Every push triggers a build in GitHub Actions or Jenkins, which runs unit tests and static analysis. The build artifacts are pushed to a container registry (ECR or Docker Hub). For deployment, I use infrastructure as code with Terraform or CloudFormation to provision resources. The pipeline then deploys the containers to a managed service such as ECS, EKS, or App Runner, or to a serverless platform like Lambda. I use blue‑green or canary deployments to minimize downtime, and I monitor the rollout with CloudWatch or Prometheus. Rollbacks are automated if health checks fail. I also maintain environment‑specific configuration via Parameter Store or Secrets Manager, and I enforce security scanning and compliance checks in the pipeline.
