Reference Architecture & Frameworks: A Consolidation

Typically, a reference architecture includes common architecture principles, patterns, building blocks, and standards.

André Christ shares his best practices

Microservices Governance: A Detailed Guide

Microservices Governance is a methodology or approach that establishes policies, standards, and best practices for the adoption of Microservices to enable an enterprise agile IT environment.

Authorization and Authentication with Microservices

Logging in to a website is so easy: I enter my username and password and can use the site. That's it.
