From APIs to Capabilities to Support AI Agents
Enterprise application architecture is once again on the verge of transformation. We’ve moved from mainframes to client-server, and recently from monoliths to microservices. Each evolution has been…

Nice write-up by @christianposta at blog.christianposta.com/api-keys-are... about AI Gateway and identity (API keys anti patterns etc)
I was thinking that a just-in-time JWT flow for creating short-lived transactional keys might be the way to solve but it requires a bit of infra

API Keys Are a Bad Idea for Enterprise LLM, Agent, and MCP Access
Do you use API keys to protect your enterprise APIs? If you work in a large enterprise organization, you probably do. This is a very common pattern. A developer can get access to an API for the application that they’re writing by requesting (tickets, self-service portal, etc) an API key. They then are responsible for keeping this key safe. The key gives the caller (their application) access to the API.

Good clarification! This is one of the most popular questions that is asked by the customers. While we propose @3scale for the api-gw, @openshift #servicemesh is recommended for handling the cluster internal service traffic and policy. https://twitter.com/christianposta/status/1244753804056129536

Istio as an Example of When Not to Do Microservices
I’ve been pretty invested in helping organizations with their cloud-native journeys for the last five years. Modernizing and improving a team (and eventually an organization’s) velocity to deliver software-based technology is heavily influenced by its people, process and eventual technology decisions. A microservices approach may be appropriate when the culmination of an application’s architecture has become a bottleneck (as a result of the various people/process/tech factors) for making changes and “going faster”, but it is not the only approach.

It was a good quick @golang intro for me as a Java developer https://dzone.com/articles/quick-go-lang-for-java-developers Thanks @christianposta. Maybe saying a little bit about concurrency would be nice:)
