Salesforce Private Connect over AWS PrivateLink does not fail loudly. It fails by working: green statuses, successful callouts, and packets still crossing the public internet because one DNS record was wrong. Here are the six failure families that actually bite, and how to prove your traffic is private.
Benchmarks pick the wrong winner. Here is how Nginx, Apache and Caddy actually differ in production: how each one fails under load, who owns certificate renewal, and where configuration lives when a developer needs to change it. Includes a decision procedure and the mistakes I see most.
Your browser shows a padlock and your partner's API client throws "unable to get local issuer certificate". Both are correct. A practical guide to the four things a TLS client actually checks, and to renewal automation that reaches the running server instead of just the disk.
Almost every TLS certificate error traces back to one of three causes: a broken chain, a hostname the certificate does not cover, or an expiry nobody was watching. Here is how to tell them apart in under a minute, and how to stop the third one from ever happening again.
