Prefer ACID over BASE - it’s easier to implement an operation as an ACID transaction rather than, for example, eventually consistent sagas.

Efficient interactions - a distributed operation that involves lots of network round trips and large data transfers can be too inefficient.

Simple interactions - an operation that’s local to a component or consists of a few simple interactions between components is easier to understand and troubleshoot than a distributed operation, especially one consisting of complex interactions.

resource requirements to improve scalability, their availability requirements to improve availability, their security requirements to improve security, etc. use current versions of languages and frameworks

Support multiple technology stacks - subdomains are sometimes implemented using a variety of technologies and developers need to evolve the application’s technology stack, e.g.

Fast deployment pipeline - fast feedback and high deployment frequency are essential and are enabled by a fast deployment pipeline, which in turn requires components that are fast to build and test.

Team autonomy - a team needs to be able to develop, test and deploy their software independently of other teams.

Simple components - simple components consisting of few subdomains are easier to understand and maintain than complex components.

How to organize the subdomains into one or more deployable/executable components? Forces It mutates and queries business entities in one or more subdomains. The subdomains implement the application’s behavior, which consists of a set of (system) operations.Īn operation is invoked in one of three ways: synchronous and asynchronous requests from clients events published by other applications and services and the passing of time. DDD aggregates) that implement business rules, and adapters, which communicate with the outside world.Ī Java-based subdomain, for example, consists of classes organized into packages that’s compiled into a JAR file. It consists of business logic, which consists of business entities (a.k.a. The team delivers a stream of small, frequent changes that are tested by an automated deployment pipeline and deployed into production.Ī team is responsible for one or more subdomains.Ī subdomain is an implementable model of a slice of business functionality, a.k.a.

In particular, it practices continuous deployment.

You need to deliver changes rapidly, frequently and reliably - as measured by the DORA metrics - in order for your business to thrive in today’s volatile, uncertain, complex and ambiguous world.Ĭonsequently, your engineering organization is organized into small, loosely coupled, cross-functional teams.Įach team delivers software using DevOps practices as defined by the DevOps handbook. You are developing a business-critical enterprise application. In my workshop, you will learn about to use Assemblage to design a microsevice architecture for your application. Java developers who want to build microservices using Red Hat Quarkus and who want to deploy them in Kubernetes.Take a look at Assemblage, a microservice architecture definition process.

Play with Quarkus and distributed application runtimes.

Boost microservices efficiency and performance with Azure.

Introduce containerization, Docker, and Kubernetes to your toolkit.

Implement the cloud and microservices patterns.

Split a monolith using the domain-driven design approach.

For experts, this book offers some recipes that illustrate how to split monoliths and implement microservices and deploy them as containers to Kubernetes.īy the end of reading this book, you will have practical hands-on experience of building microservices using Quarkus and you will master deploying them to Kubernetes. For those who are new to enterprise development using Quarkus, you will be introduced to its core principles and main features through a deep step-by-step tutorial.

You will be guided on how to install the appropriate tools to work properly. It will introduce Docker and Kubernetes to help you deploy your microservices. Build and design microservices using Java and the Red Hat Quarkus Framework. This book will help you quickly get started with the features and concerns of a microservices architecture.
