Mauro Servienti

The document discusses the design and management of microservices, particularly in the context of shopping cart and product functionalities. It emphasizes the importance of defining business requirements, managing service boundaries, and the implications of latency on sales. Key takeaways include the significance of boundaries in system design, the impact of premature naming on data aggregation, and the need to utilize messaging for service decoupling.

@mauroservienti What a (micro)service is not • A service that has only functionality is a function: • Like calculation, validation, etc. • A service that has only data is a database: • Like [create, read, update, delete] entity • HTTP/WSDL doesn’t change logical responsibility

@mauroservienti Takeaways • Boundaries are key to success • Do not bring in more technology to solve non- technical problems
@mauroservienti Takeaways • Boundaries are key to success • Mental model can badly influence design • Users/Business analysts tend to think in term of data presentation
@mauroservienti Takeaways • Boundaries are key to success • Mental model can badly influence design • Do not name things prematurely • Premature names stick and drive data aggregation
@mauroservienti Takeaways • Boundaries are key to success • Mental model can badly influence design • Do not name things prematurely • Behaviors define how to aggregate data • Group data that change together and that influence each other • Use anti-requirements techniques to validate data grouping • Follow the coupling
@mauroservienti Takeaways • Boundaries are key to success • Mental model can badly influence design • Do not name things prematurely • Behaviors define how to aggregate data • Use messaging to temporally decouple services
