What you'll learn

By the end of this two-day training course, attendees will understand: The essential characteristics of the microservice architecture, its benefits and drawbacks and when to use it Distributed data management patterns Effective microservice testing strategies Deployment options for microservices Strategies for refactoring a monolithic application to a microservice architecture And they’ll be able to: Architect an application as a set of microservices Use sagas to maintain data consistency Implement queries that span services Test microservices Refactor a monolith to services

Description

Enterprises need to deliver better software faster. It’s no longer sufficient to release quarterly or even monthly. Instead, organizations must use methods, such as DevOps, to frequently deploy changes into production, perhaps as often as multiple times per day. One obstacle, however, to DevOps-style development is that organizations are often mired in monolithic hell. Key business applications are large, complex, unwieldy monoliths, and so it’s impossible to rapidly and safely deploy changes.

The solution is to adopt the microservice architecture, which is an architectural style that has the testability and deployability necessary for DevOps. In this workshop, you will, through a combination of lectures, discussions and katas, learn how to use the microservice architecture to develop your applications. We will describe how to solve some of the key obstacles you will face including distributed data management. You will learn about strategies for refactoring a monolith to a microservice architecture.

Day One:

Overview of the microservice architecture
* The microservice architecture as an architectural style
* Benefits and drawbacks of microservices
* The microservice pattern language

Decomposition
* Overview of decomposition
* Decompose by business capabilities
* Decompose by bounded context
* Service design guidelines

Maintaining data consistency
* Overview
* Maintaining consistency using sagas
* Coordinating sagas
* Countermeasures for data anomalies

Querying
* Overview
* Using the API composition pattern
* Using the CQRS pattern

Day Two:

 Inter-process communication

* Overview of  inter-service and external communication

* Using an API Gateway

* Service discovery

 Testing strategies

* Introduction to the testing pyramid

* Writing consumer-driven contract tests

* Developing component tests

* Developing end to end tests

 Overview of deployment patterns

* Multiple services per host

* Service per VM

* Service per container

* Serverless deployment

 Refactoring

* Incrementally refactoring a monolith into microservices

* Strategy #1: stop digging

* Strategy #2: split front-end & backend

* Strategy #3: extract services
