iSAQB keynote - Modular monoliths and microservices: architectural patterns for rapid, reliable, frequent and sustainable development

In October 2021, I gave a keynote at iSAQB software architecture gathering 2021. I use the metaphors of dark energy and dark matter to compare and contrast three architectural patterns: traditional monolith, modular monolith and microservices.

Dark energy vs. dark matter

  • Dark energy is a metaphor for repulsive forces that encourage decomposition
  • Dark matter is a metaphor for attractive forces that resist decomposition

Pick an architecture pattern that balances these forces

Comparing the monolithic architecture and the microservice architecture

Abstract

Rapid, reliable, frequent and sustainable software development requires an architecture that is loosely coupled and modular. Teams need to be able complete their work with minimal coordination and communication with other teams. They also need to be able keep the software’s technology stack up to date. However, the microservice architecture isn’t always the only way to satisfy these requirements. Yet, neither is the monolithic architecture.

In this talk, I describe loose coupling and modularity and why they are is essential. You will learn about three architectural patterns: traditional monolith, modular monolith and microservices. I describe the benefits, drawbacks and issues of each pattern and how well it supports rapid, reliable, frequent and sustainable development. You will learn some heuristics for selecting the appropriate pattern for your application.

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.

Learn how to create a service template and microservice chassis

Take a look at my Manning LiveProject that teaches you how to develop a service template and microservice chassis.

New 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 JUNVCEJE to sign up for $195 (valid until February 1st, 2023). There are deeper discounts for buying multiple seats.
