Jsmapreduce

jsmapreduce is the simplest full-featured big data infrastructure available. founded by an early google engineer, jsmapreduce requires no client installation or compilation. and it is the first truly debuggable mapreduce solution. you develop your big data app as a mapreduction directly in the browser, test it in the browser, then deploy to the cloud to run at scale. if anything goes wrong, you can debug the problem mapper or reducer shard right back in the browser. it's all automatic. jsmapreduce is fully transparent. developing and testing your app in-browser is free. when running in the cloud, you get second-by-second updates on progress and cost.
