Shopify operates at massive scale, running thousands of services and processing billions of events per second. To tackle the challenges of observability at this scale, they built Observe—an in-house observability stack that makes use of open-source tools and specifications. In fact, they replaced an older vendors-based system, in an awe-inspiring migration project. But why build their own stack? Which open source tools did they use? How did they shape the user experience to their needs?

Joining us to unpack Shopify’s journey is Elijah McPherson, an engineering leader with deep expertise in observability and distributed systems. Elijah led the complete rebuild of Shopify’s observability stack and now also oversees jobs, caching, search, and ClickHouse infrastructure. Tune in to hear firsthand insights from one of the most innovative purpose-built observability implementations in production today!
