quote: U.S. Government’s Cloud Computing Requirements

leave a comment »

“… cloud service level agreements must provide for at least 99.95% availability, vendors have to take steps to secure their services, and trouble tickets and order management need to be able to be done via API. Virtual machine services must allow live migration of workloads from one VM to another, while Web hosting services require both Windows and Linux options….”

“The concept of starling is to have a single server handle reliable, ordered message queues. When you put a cluster of these servers together, with no cross communication, and pick a server at random whenever you do a set or get, you end up with a reliable, loosely ordered message queue.

“In many situations, loose ordering is sufficient. Dropping the requirement on cross communication makes it horizontally scale to infinity and beyond: no multicast, no clustering, no “elections”, no coordination at all. No talking! Shhh”

hadoop-scale

“Hundreds of gigabytes of data constitute the low end of Hadoop-scale. Actually Hadoop is built to process “web-scale” data on the order of hundreds of gigabytes to terabytes or petabytes. At this scale, it is likely that the input data set will not even fit on a single computer’s hard drive, much less in memory. So Hadoop includes a distributed file system which breaks up input data and sends fractions of the original data to several machines in your cluster to hold.”
