Slide 145

Slide 145 text

In short, the microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API. These services are built around business capabilities and independently deployable by fully automated deployment machinery. There is a bare minimum of centralized management of these services, which may be written in different programming languages and use different data storage technologies.

Slide 155

Slide 155 text

WHAT DID WE LEARN SO FAR? Define goals and purpose Take baby steps Define your roadmap Set up you guiding principles Model your landscape Apply evolutionary architectures Define your patterns Build apps as microservices Design for single responsibility Split in bounded contexts and aggregates Foster immutability Let services own their data Standardize your API design Avoid point-to-point contracts Interface defensively Architecture follows communication channels and vice versa Test from day one Secure by design Deploy independently and continuously Become cloud native Don’t innovate commodities Choose a cloud for simplicity and ease-of-use
