Securely Connect AWS DevOps Agent to Private Services in Your VPCs

AWS DevOps Agent is useful until it has to talk to something that sits behind a private subnet. Then the architecture problem is no longer about prompts or models. It is about how to give the agent a private path without turning your internal service into a public endpoint.

AWS answered that in the April 2026 post by using a VPC Lattice resource gateway. The pattern is simple enough to explain and strict enough to be safe: the agent creates a managed path into your VPC, the service stays private, and your security groups still decide what is reachable.

Connection Table

Component	Role	What you configure	Gotcha
AWS DevOps Agent	Initiates the request	Agent Space and private connection	It cannot reach private endpoints by default
Resource gateway	Managed entry point	VPC, subnets, and optional security groups	Only the service can route through it
ENIs in your subnet	Private traffic path	Subnet placement and SG rules	They are not public interfaces
Target service	Internal API, MCP server, or observability tool	DNS name or IP target	Public DNS name may still be required
CloudTrail	Audit trail	Org logging and trail retention	You want proof of who created the path

Traffic Flow

Why This Matters

This is the safer version of the old “just put it behind a bastion” story. You do not need to publish a service on the public internet just because an AI tool needs to reach it. That matters for internal dashboards, self-hosted observability, and private package registries, which are exactly the kinds of systems teams attach to DevOps Agent first.

The operational gotcha is that this is not a generic tunnel. It is an opinionated network path with AWS-managed pieces. If you already use PrivateLink or a centralized network model with Transit Gateway, treat this as another private access option, not a replacement for the network design you already have.
