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.

New workshop: Architecting for fast, sustainable flow

Enabling DevOps and Team Topologies thru architecture

DevOps and Team topologies are vital for delivering the fast flow of changes that modern businesses need.

But they are insufficient. You also need an application architecture that supports fast, sustainable flow.

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 ILFJODYS to sign up for $95 (valid until April 12, 2024). There are deeper discounts for buying multiple seats.
