Traditional software monitoring platforms collect observability data in three main formats: Logs: Timestamped records of an event or events. Especially in dynamic microservices architectures, distributed tracing is essential to monitor, debug, and optimize distributed software architecture, such as microservices.

One of the main advantages we also saw in having an app with clear boundaries is our testing strategy?—?the the majority of our tests can verify our business logic without relying on protocols that can easily change. We knew that a prerequisite to great development velocity was to have a test suite that is reliable and super fast.
