Kubernetes vs Docker Compose for a 3-service product on a single VM
Scalability ↔ Simplicity
Context
Choose the deployment model for an early-stage product.
Three services (API, worker, web) plus Postgres and Redis. Under 50 req/s. A contractor proposed EKS "so we're ready to scale". Monthly cost would go from ~$80 to ~$400 before any workload.
Is there a middle ground (ECS, Fly.io, Nomad, k3s) or is Compose on a VM with a good backup story genuinely fine at this stage?

Sign in to commentCompose + systemd + automated backups + a second VM for blue/green will carry you to real product-market fit. Re-evaluate when you need more than one machine for the workload, not for the resume.
If anyone on the team already knows Kubernetes, a managed control plane is less scary than it looks — and you get rolling deploys and health checks for free. But EKS at $400/month for 50 rps is hard to justify.
ECS Fargate is the honest middle ground on AWS. Rolling deploys and health checks without running a cluster.
