The build was passing, the deploy was green, but nothing could reach your service.
That’s when you learn the hard truth about connecting apps inside an MVP VPC private subnet. Without direct internet access, you need a proxy. Not an afterthought. Not a hack. A deliberate, secure, scalable proxy deployment.
An MVP VPC private subnet isolates resources from the public internet. This hardens security by controlling inbound and outbound traffic. But isolated means silent. Services in private subnets can’t fetch updates, hit APIs, or talk to external systems without a controlled exit. That’s where a proxy comes in.
A proxy in this setup is usually deployed in a public subnet or as a managed NAT gateway. It handles outbound traffic while keeping your core resources fully private. The pattern is simple: private subnet workloads route through the proxy, which authenticates, logs, and forwards requests. This ensures compliance while preserving the ability to access required external resources.
Steps to deploy an MVP VPC private subnet proxy:
- Design your subnet layout. One or more private subnets for workloads, a single public subnet for the proxy or NAT.
- Configure route tables so private subnet traffic targets the proxy.
- Lock down security groups to allow only necessary outbound ports.
- Use high-availability configurations across multiple Availability Zones.
- Add logging and monitoring for traffic visibility.
Choosing between a NAT gateway and a custom proxy server depends on cost, control, and complexity. NAT gateways are quick to set up and scale automatically. Custom proxies (like Squid or Envoy) deliver finer control and advanced filtering but require maintenance. For an MVP, you want deployment speed and low friction, but you also want a path to production readiness without re-architecting later.
A private subnet with a proxy is not just a network choice. It is a guardrail that lets you build fast inside a secure perimeter. It prevents the slow creep of unmonitored connections that often plague early-stage architectures.
