Salesforce: Migrating a Monolithic Cloud with Temporal

Abstract

Migrations are hard. Migrating a large, monolithic application spanning 1000+ engineers is harder. Salesforce at-large is in the middle of a transformation to deliver all products and solutions on Hyperforce. Marketing Cloud – one of the Salesforce’s earliest acquisitions – is a massive multi-tenant application that spans dozens of teams. This presents significant challenge when moving to a new environment.

At Replay 2024, Salesforce presented on how we deliver Temporal at scale across the company. Over the past year, more critical work has been built on the platform. In this talk we’ll cover one of the most important use cases that was delivered: a cross-substrate migration system.

This talk will cover Temporal’s role in how we migrated Marketing Cloud across substrates, how we plugged-in many different teams into the process, and, finally, the learnings we’ve had along the way.
