How do you know when a service needs to evolve? While we often focus on REST APIs and runtime behavior, the true scope of a service could extend beyond these interfaces.

Through the journey of a critical booking service at loveholidays, Stuart will explore how 12 years of rapid organisational growth created unexpected challenges in both our runtime and data architectures.

Gain practical insights about recognising when your service boundaries no longer serve your teams, how 'hidden' APIs like data dependencies can impact your ability to evolve, and how loveholidays approached restructuring for future scalability while keeping their systems running smoothly. This real-world case study demonstrates how to systematically untangle and evolve critical services as your organisation grows.
