Microservice Architecture
Supported by KongGOTO Chicago presentation: Not Just Events - Developing Asynchronous Microservices
Earlier this year, I gave a talk at GOTO Chicago on how to solve distributed data management problems in a microservice architecture using asynchronous messaging. I described how to implement transactions using the Saga pattern and implement queries using the CQRS pattern. Both patterns rely on asynchronous messaging between services.
Abstract
The microservice architecture functionally decomposes an application into a set of services. Each service has its own private database that’s only accessible indirectly through the services API. Consequently, implementing queries and transactions that span multiple services is challenging.
In this presentation, you will learn how to solve these distributed data management challenges using asynchronous messaging. Chris will share with you how to implement transactions using sagas, which are sequences of local transactions. You will learn how to coordinate sagas using either events or command messages. Chris will also explore how to implement queries using Command Query Responsibility Segregation (CQRS), which uses events to maintain easily queried replicas.

About Microservices.io
Microservices.io is brought to you by Chris Richardson. Experienced software architect, author of POJOs in Action, the creator of the original CloudFoundry.com, and the author of Microservices patterns.
Chris helps clients around the world adopt the microservice architecture through consulting engagements, and training workshops.
MICROSERVICES WORKSHOPS
Chris teaches comprehensive workshops for architects and developers that will enable your organization use microservices effectively.
Avoid the pitfalls of adopting microservices and learn essential topics, such as service decomposition and design and how to refactor a monolith to microservices.

Virtual bootcamp: Distributed data patterns in a microservice architecture
My virtual bootcamp, distributed data patterns in a microservice architecture, is now open for enrollment!
It covers the key distributed data management patterns including Saga, API Composition, and CQRS.
It consists of video lectures, code labs, and a weekly ask-me-anything video conference repeated in multiple timezones.
The regular price is $395/person but use coupon MECNPWNR to sign up for $120 (valid until May 16th, 2023). There are deeper discounts for buying multiple seats.
