Q: What is Amazon SWF?
Amazon Simple Workflow Service (SWF) is a web service that makes it easy to coordinate work across distributed application components. Amazon SWF enables applications for a range of use cases, including media processing, web application back-ends, business process workflows, and analytics pipelines, to be designed as a coordination of tasks. Tasks represent invocations of various processing steps in an application which can be performed by executable code, web service calls, human actions, and scripts.
The coordination of tasks involves managing execution dependencies, scheduling, and concurrency in accordance with the logical flow of the application. With Amazon SWF, developers get full control over implementing processing steps and coordinating the tasks that drive them, without worrying about underlying complexities such as tracking their progress and keeping their state. Amazon SWF also provides the AWS Flow Framework to help developers use asynchronous programming in the development of their applications. By using Amazon SWF, developers benefit from ease of programming and have the ability to improve their applications’ resource usage, latencies, and throughputs.
