How EC2 changes the game in batch grid computing – RightScale Blog
Enter Amazon EC2. If user A enqueues a job needing 500 nodes for 10 hours and user B a job needing 800 nodes for 5 hours what do you do? Very simple: you check the balance in their account and then start 500 instances for user A and 800 instances for user B. Done. No priorities, no scheduling, just pure compute fun!
One of us (Ed) observed: the resource that is “allocated” in the finite computer center is the use of hardware, but the resource that is “managed” in a Cloud is cost. It is a new mind set that 1 computer for 100 hours has the same cost as 100 computers for 1 hour. Of course there are details such as start up costs for large numbers of nodes and ensuring that each billed instance hour is fully used. But those details are a small leap when compared to the issue of understanding that 1=100.
Source: Google To Launch BigTable As Web Service – TechCrunch
Google may be releasing BigTable, its internal database system, as a web service to compete with Amazon SimpleDB, according to a source with knowledge of the launch. There are also rumors that press is being pre-briefed on the product, although we haven’t been contacted by Google.
BigTable is a highly scalable database system used internally by Google to support over 60 of its products and projects. A source says Google has plans to announce next week that it will make BigTable available to outside developers as a service. Amazon provides a similar service through SimpleDB, a cloud database solution announced in December.
