Workflows patterns and best practices - Part 2

This is part 2 of a three-part series of posts, in which we summarize Workflows and service orchestration patterns. You can apply these patterns to better take advantage of Workflows and service orchestration on Google Cloud.

In the first post, we introduced some general tips and tricks, as well as patterns for event-driven orchestrations, parallel steps, and connectors. This second post covers more advanced patterns.

Let’s dive in!

Design for resiliency with retries and the saga pattern It’s easy to put together a workflow that chains a series of services, especially if you assume that those services will never fail. This is a common distributed systems fallacy, however, because of course a service will fail at some point. The workflow step calling that service will fail, and then the whole workflow will fail. This is not what you want to see in a resilient architecture. Thankfully, Workflows has building blocks to handle both transient and permanent service failures.
