AWS ECS Fargate
Amazon's serverless container runtime — runs Docker containers without managing EC2 instances; pay per vCPU/GB-hour.
ECS Fargate is the default modern AWS container target for small-to-mid B2B SaaS. You define a task definition (image, vCPU, RAM, ports) and Fargate provisions the underlying compute, networking, and IAM. Combine with Application Load Balancer (ALB) for HTTPS, AWS Secrets Manager for env, Aurora Postgres for DB. Cheaper than EKS for ≤30 containers, simpler than Lambda for long-running web apps.
