Comparing GCP Workflows, AWS Step Functions, and Temporal for Stateful Workflow Orchestration

Stateful workflow orchestration tools play a crucial role in enabling engineers to effectively manage complex multi-step processes across various services. When it comes to choosing the right tool for stateful workflow orchestration, three popular options stand out: Google Cloud Workflows (GCP Workflows), AWS Step Functions, and Temporal.

Workflow Modeling Approach

In terms of workflow modeling approach, GCP Workflows and AWS Step Functions take a declarative approach to defining workflows. AWS Step Functions leverage the Amazon States Language, a JSON-based language with YAML support for defining states and transitions within a workflow. Furthermore, AWS offers a visual designer through Workflow Studio to facilitate workflow design.

On the other hand, Google Cloud Workflows use a YAML-based DSL or JSON to describe a sequence of steps that execute sequentially. In GCP Workflows, steps naturally flow to the next step unless specified otherwise, resembling a coding style. Both GCP Workflows and AWS Step Functions support conditional branches and loops, allowing for complex workflow logic to be defined through configurations rather than extensive coding.
