Workflows are great for orchestrating services, functions, or events. They provide out-of-the-box features to make your applications resilient, reliable, and simple.

But currently, each cloud vendor has its workflow solution. AWS has Step Functions, Google has Google Workflows, Microsoft has Azure Durable functions, and so on. The lack of a common way to define workflows becomes an issue when you need to migrate or host your applications on more than one cloud vendor. It also limits the potential for creating tools and infrastructures that support several platforms. This is what the Serverless Workflow specification addresses.
