Microservice Architecture
Supported by Kong
My YOW! 2018 presentation: Events and Commands: Developing Asynchronous Microservices
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. I describe how to implement transactions using sagas, which are sequences of local transactions, coordinated using messages. You will learn how to implement queries using Command Query Responsibility Segregation (CQRS), which uses events to maintain replicas. I describe how to use event sourcing, which is an event-centric approach to business logic and persistence, in a microservice architecture.

This book teaches enterprise developers and architects how to build applications with the microservice architecture. Rather than simply advocating for the use the microservice architecture, this clearly-written guide takes a balanced, pragmatic approach, exploring both the benefits and drawbacks.Learn more

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 JIBFGJFJ to sign up for $95 (valid until May 16th, 2025). There are deeper discounts for buying multiple seats.
