Amazon's Simple Workflow and Software Defined Networks could transform cyber-infrastructure

[It is very exciting to see Amazon’s new simple Workflow service. Workflow, when combined with software defined networks, could transform the future of cyber-infrastructure or eInfrastructure.
Large scale instruments could forward their data sets and/or streams to Amazon for processing over specially configured networks designed to link together databases, Amazon web services, visualization engines and off site storage. A great example is how NASA is using Amazon’s Simple Workflow for processing images from the Mars landers. This is the fulfillment of the promise of UCLP – to build what we called “Articulated Private Networks” where every network element, computation, node, instrument was represented as a web service which could composed into a end to end network solution using BPEL workflows by the end user. This new Amazon service gives you the ability to build and run distributed, fault-tolerant applications with MapReduce and Hadoop that span multiple systems (cloud-based, on-premise, or both) which further enables deployment of zero carbon networks and clouds such as Greenstar or Hewlett-Packard GreenCloud. – BSA]
