Avoid Tight Coupling Between Modules
One of the key red flags to watch out for when hiring a consultant or assessing an architecture is tight coupling between modules. Direct calls between modules or sharing the same database can hinder modularity and independence of components.
Start with Simple Vertical Slices
When modularizing a monolith, start with simple vertical slices that are easy to separate. For example, creating a module for handling email communication can serve as a foundational example. By beginning with simple modules, you can address distributed communication challenges and learn from the process for more complex modules.
Utilize CQRS for Command-Query Segregation
Command Query Responsibility Segregation (CQRS) can be beneficial in structuring the communication between components. Separating the writing and reading data paths helps manage consistency and availability of services. CQRS aligns well with defining messages for queries, commands, and events.
Consider Materialized View Pattern for Data Queries
To address data retrieval in modular architectures, consider implementing a materialized view pattern where data is duplicated locally for querying. By updating a cache based on events and messages from other modules, you can ensure availability of data, especially for read-intensive operations.
Transitioning from Microservices to Modular Monoliths Course
For those navigating challenges with microservices, a course on transitioning from microservices to modular monoliths can provide insights on simplifying architecture and preserving modularity. Understanding the backward journey from microservices to monoliths while maintaining modularity can offer practical solutions for complex architecture needs.
Modular Monoliths strike the middle ground between monoliths and microservices! Carl and Richard talk to Steve Smith about his work striking a balance between the simplicity of a monolithic set of services and the complexity of breaking everything into microservices. Steve discusses the performance and simplicity advantages of monoliths and only breaking out services with specific needs into separate services. .NET has excellent tooling to help you evaluate, test, and manage your modular monoliths!
