Serverless is a game-changer for speed, but for those in regulated industries (Finance, Healthcare, Public Sector), the default behaviour of Cloud Run (public URLs for everything) is often a non-starter.

Historically, solving this meant complex VPNs or messy VPC peering. But there is a better, modern architectural pattern: Private Service Connect (PSC).

I just published a deep-dive technical guide on lineargs.dev exploring how to architect a "Zero Trust" serverless environment.

In this article, I cover: ✅ The Architecture: How to keep your traffic "dark" to the public internet using Internal Load Balancers and Serverless NEGs. ✅ The "How-To": A step-by-step implementation guide (gcloud commands included). ✅ The "Gotchas": Solving the DNS resolution headaches and SSL certificate management. ✅ The Networking: Bypassing CIDR overlaps and securing cross-project boundaries.

If you are modernising legacy workloads but stuck on security compliance, this architecture is your bridge.
