How to Find Service Boundaries in Service-Oriented Architecture

TLDRLearn how to effectively identify and define service boundaries in service-oriented architecture.

Key insights

🔍Understanding the core concepts of service-oriented architecture is essential for finding service boundaries.

🌐Service boundaries should be designed based on business capabilities to ensure alignment with the problem domain.

🙅‍♂️Avoid sharing databases between services to minimize hidden coupling and maintain autonomy.

📚Leverage message schemas to model explicit coupling and define the responsibilities of each service.

⚖️Consider the trade-offs and advantages of making certain functions remotely callable in a service-oriented architecture.

Q&A

What are the key insights for finding service boundaries?

The key insights include understanding service-oriented architecture concepts, designing boundaries based on business capabilities, avoiding shared databases, utilizing message schemas, and considering the advantages of remote function calls.

Why is it important to align service boundaries with the problem domain?

Aligning service boundaries with the problem domain ensures that the architecture meets the specific needs of the business and promotes high cohesion and loose coupling.

What risks are associated with sharing databases between services?

Sharing databases can lead to hidden coupling, where changes to one service's database schema inadvertently break other services that rely on it.

How can message schemas help in defining service boundaries?

Message schemas provide a clear and explicit definition of the data and communication between services, enabling decoupling and encapsulation.

When should functions be made remotely callable in a service-oriented architecture?

The decision to make functions remotely callable should consider the advantages, such as offloading CPU-intensive tasks, while being aware of the potential drawbacks, such as network-related issues.
