Quietly Strangling the Monolith – a real-world migration of a high traffic monolith

From the classroom computer of an A-Level teacher in Skegness, ScholarPack has become the fastest-growing School Management System in England. A typical school day sees us taking around 50,000 class registers, serving 30,000 users and in excess of 65k requests/second.

That rapid growth has been driven by the continuous rollout of new features to meet the evolving needs of schools and stay ahead of the competition. The result has been a sprawling monolith at the backend, based around a legacy framework.

Schools may love the product, but it’s a different story for the developers working on it and the DevOps keeping it running.

Over the last three years, we have embarked on a program to “strangle the monolith”, moving from the sprawling mess to a scalable, maintainable series of services that are more secure and a pleasure to work on. All this whilst making the transition invisible to the end-user.

In this talk, I go through the experience of architecting the new world, the technologies and techniques employed, motivating and upskilling a team and how iterative development and architecture lead to a stable and scalable path.
