Introducing AWS Step Functions
AWS Step Functions makes it easy to coordinate the components of distributed applications and microservices using visual workflows. Building applications from individual components that each perform a discrete function lets you scale and change applications quickly. Step Functions is a reliable way to coordinate components and step through the functions of your application. Step Functions provides a graphical console to arrange and visualize the components of your application as a series of steps. This makes it simple to build and run multi-step applications. Step Functions automatically triggers and tracks each step, and retries when there are errors, so your application executes in order and as expected. Step Functions logs the state of each step, so when things do go wrong, you can diagnose and debug problems quickly. You can change and add steps without even writing code, so you can easily evolve your application and innovate faster.
AWS Step Functions manages the operations and underlying infrastructure for you to help ensure your application is available at any scale.
With AWS Step Functions you pay only for the transition from one step of your application workflow to the next, referred to as a state transition. Billing is metered by state transition, regardless of how long each state persists (up to one year). The AWS Step Functions free tier includes 4,000 state transitions each month.
AWS Step Functions is now available in the US East (N. Virginia), US East (Ohio), US West (Oregon), EU (Ireland) and Asia Pacific (Tokyo) regions.
