Web Hosting NewsSEATTLE – Amazon Web Services LLC (AWS), an company (NASDAQ:AMZN), today introduced Amazon Simple Workflow Service (Amazon SWF), a workflow service for building scalable, resilient applications. Whether automating business processes for finance or insurance applications, building sophisticated data analytics applications, or managing cloud infrastructure services, Amazon SWF reliably coordinates all of the processing steps within an application.

With traditional development approaches, it is both time-consuming and costly to build and track processing steps that run at different processing times and have different durations, while ensuring they are executed reliably and without duplication. When the execution of applications is distributed across multiple systems, the coordination of processing steps across those systems presents an added challenge. Using Amazon SWF, developers can structure the various processing steps in an application as “tasks” that drive work in distributed applications, and Amazon SWF coordinates these tasks in a reliable and scalable manner. Amazon SWF manages task execution dependencies, scheduling, and concurrency based on a developer’s application logic. The service stores tasks, reliably dispatches them to application components, tracks their progress, and keeps their latest state.

“With Amazon SWF, developers can now easily coordinate distributed application components across on-premises and cloud environments using their choice of programming languages,” said Reto Kramer, General Manager, Application Connection Services, AWS. “By relying on Amazon SWF to handle the coordination of distributed task execution, developers can now focus on building the differentiating aspects of their applications and leave the undifferentiated heavy lifting of building and managing workflow engines to AWS.”

NASA Jet Propulsion Lab (JPL) uses Amazon SWF as part of several space and earth science missions including the Mars Exploration Rover. Amazon Simple Workflow Service gives JPL the ability to leverage resources inside and outside of its environment enabling their applications to dynamically scale and run in a truly distributed manner. NASA JPL has integrated Amazon SWF into their Cloud Oriented Architecture and its reference implementation, Polyphony. Amazon SWF is now an integral part of the software engineer’s toolbox at JPL.

More details about the features in Amazon SWF and the benefits of building applications using Amazon SWF can be found by visiting The service is currently available in the US East (Virginia) Region and will be available in other AWS Regions in the coming months.

About Amazon Web Services
Launched in 2006, Amazon Web Services (AWS) began exposing key infrastructure services to businesses in the form of web services — now widely known as cloud computing. The ultimate benefit of cloud computing, and AWS, is the ability to leverage a new business model and turn capital infrastructure expenses into variable costs. Businesses no longer need to plan and procure servers and other IT resources weeks or months in advance. Using AWS, businesses can take advantage of Amazon’s expertise and economies of scale to access resources when their business needs them, delivering results faster and at a lower cost. Today, Amazon Web Services provides a highly reliable, scalable, low-cost infrastructure platform in the cloud that powers hundreds of thousands of enterprise, government and startup customers businesses in 190 countries around the world. AWS offers over 21 different services, including Amazon Elastic Compute Cloud (Amazon EC2), Amazon Simple Storage Service (Amazon S3) and Amazon Relational Database Service (Amazon RDS). AWS services are available to customers from data center locations in the U.S., Brazil, Europe, Japan and Singapore.
