Don’t Build a Distributed Monolith: How to Avoid Doing Microservices Wrong - Jonathan J. Tower

Learn how to avoid common pitfalls in microservices architecture, including the distributed monolith, and discover the right approach to scaling and maintaining a successful microservices system.

Key takeaways
  • Microservices are not always the best solution, and it’s essential to understand the reasons for and against them.
  • Avoiding anti-patterns like the distributed monolith is crucial in microservice architecture.
  • Start by having a small team working on a monolithic application and then gradually break it down into microservices.
  • Monoliths can be scalable and are better at some things, such as data consistency, than microservices.
  • Microservices are suitable for applications that require independence, scalability, and high availability.
  • Organize your teams around business capabilities, not just technology, to achieve a more effective architecture.
  • Use events to communicate between microservices and maintain eventual consistency.
  • Avoid creating a distributed monolith by keeping data and services separate and not sharing databases.
  • Use services like Kafka or Azure Event Bus for event-driven development. *logging is essential in microservices architecture, and it’s better to use existing libraries rather than creating your own.
  • Don’t assume that microservices are inherently better than monoliths; each has its advantages and disadvantages.
  • When migrating to microservices, consider starting with a small team and gradually expanding to others.
  • Don’t reuse the same technology stack for every microservice; instead, choose the best technology for each service.
  • Use NuGet to manage dependencies and reduce coupling between services.
  • Avoid over-complicated event-driven architecture and focus on simplicity and maintenance.
