Check: Durable Payroll in a Modular Monolith

Abstract

Check’s monolith powers a scaled payroll platform. By combining the principles of microservices with durable execution, we’ve transformed how we build software reliably and quickly in our monolith. As we’ve moved away from our previous systems of coordinated crons and Celery tasks to Temporal, we’ve seen huge leaps in reliability, debuggability, performance, and speed of development, to name a few. And we’ve only just gotten started!

In this talk, we’ll cover:

What brought us to Temporal, including the questions we answered along the way, like “does this even make sense in a monolith?” Technical tips and stories along the adoption curve to unlock capabilities like new task queues and safe, scalable workflows in minutes. Where we’ll grow with Temporal in the future, covering team-specific SLOs and workflow metrics. Join us and hear our lessons learned and our future of using Temporal to pay billions in wages, file taxes, stop fraud, and more.
