Microservice Architecture
Supported by KongNew conference talks on asynchronous microservices: implementing Sagas and CQRS (#GotoChgo, #microcph)
I recently gave talks at a couple of conferences.
GOTO Chicago - Not Just Events: Developing Asynchronous Microservices
The first talk was at GOTO Chicago. This talk described 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.
MicroCPH - Managing data consistency in a microservice architecture using Sagas
My second talk was at MicroCPH in Copenhagen, Denmark. It focussed on implementing transactions that span services using the Saga pattern

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.

Remote consulting session
Got a specific microservice architecture-related question? For example:
- Wondering whether your organization should adopt microservices?
- Want to know how to migrate your monolith to microservices?
- Facing a tricky microservice architecture design problem?
Consider signing up for a two hour, highly focussed, consulting session.
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 RESVJCMC to sign up for $95 (valid until September 26th, 2023). There are deeper discounts for buying multiple seats.

The Eventuate platform
Use the Eventuate.io platform to tackle distributed data management challenges in your microservices architecture.
Eventuate is Chris's latest startup. It makes it easy to use the Saga pattern to manage transactions and the CQRS pattern to implement queries.
