When your infrastructure runs inside a VPC private subnet, the smallest misstep in resource profiles or proxy configuration can grind everything to a halt. The dependencies vanish behind security groups, NATs, and routing tables. The logs turn cryptic. Latency creeps in. You need a workflow that defines Infrastructure Resource Profiles exactly, deploys a proxy correctly, and keeps it invisible to the wrong eyes but perfectly reachable to the right services.
A clean deployment begins with a dedicated VPC private subnet. Isolation is key. Keep external traffic out. Define each Infrastructure Resource Profile with clarity—CPU, memory, disk, network. Never overload your instance types in ways that throttle I/O in peak moments. Map these resources directly to the workloads the proxy will serve.
The proxy in a private subnet cannot rely on default internet gateways. It needs a secure path. Often that's through a NAT Gateway or VPC endpoint, depending on whether the proxy must reach outside APIs or simply connect internal services. The Infrastructure Resource Profile should embed these networking requirements, so your deployment remains reproducible and consistent across environments.
