Agile + DevOps West 2019 - Architecture - Design

Server-side monoliths—single programs that provide all back-end services—just don't work. They are hard to build, impossible to maintain, and gradually accrete so much baggage that forward development slows to a crawl. Agile development is impossible over this sort of system. Allen Holub says that microservices—systems of small, cooperating server-side agents—solve these problems. However, building a microservice system is not easy, and doing it wrong is disastrous. Taking a deep dive into practical microservice architecture and implementation, Allen covers a lot of practical details to...

A best practice of software architecture is to design your applications into independent modules or components, with a published contract for interaction between components. This is a principle of the microservices style of architecture, but it also applies to components created in a large monolith. If we can test the functionality of the component independently, and apply a level of trust that those components work, this opens the door to rethinking our continuous integration and continuous delivery strategy, potentially reducing the need for long test suites and many environments. It...
