Summary: Linux has come a long way from its modest roots in the early 1990s to now being the operating system of choice for data center deployments. Join Oracle's Chief Corporate Architect, Edward Screven, as he discusses the importance of Linux in the industry, and how Oracle views and supports Linux. Edward will also highlight his thoughts on advancements needed and being made in Linux that will continue to keep it on the top.
Why Does Oracle Care About Linux?
Oracle wanted customers to try to standardize on shared pools of low-cost servers and storage as a way to save money on hardware, break down the existing Silos within the data center, and simplify the growing heterogeneity of Data Centers. Windows was not a realistic option, BSD was considered but Linux appeared to have a better chance, although in hindsight, this relatively pivotal decision was as much luck as it was a good choice.
In 2002, Larry Ellison said "We will run our whole business on Linux". Today that statement is true.
Chuck Rozwat said "We will run our base development on Linux for all of our products" Today they do.
Oracle Enterprise Linux is primarily a support business exactly tracking Red Hat Linux.
$954 million in 2006 to 1.2 billion in 2007 (Gartner) makes Linux servers the fastest growing OS sub segment, growing 25.6% over that time period.
Oracle claims that they may be the world's largest user of Linux, including their Traditional IT, Development, Oracle On Demand, and Oracle University. 84,000 servers, 10 PB storage, all running Linux. 1000 dual CPU machines in "The Farm" - their test grid. 75% running Linux, 2000 jobs run simultaneously.
What helps linux succed in the data center?
- Cost effective - total cost and marginal cost
- Standards Based, extensible, 3rd party support, open
- Enterprise Ready - scalable, reliable, manageable (at the individual box level)
- Tested configuration ready to deploy
- Enterprise-Class Integrated Support
Oracle strongly believe that Virtualizatoin Changes the Game - turns pools of servers into a fungible resource. Oracle VM is a product in this space, based on Xen, supports Linux & Windows.
Used in Oracle University, 1/6th the hardware, CPU utilization increased from 7% to 73%, Servers to administrator ratio increased 10X, Revenue per server increased 5X.
In Oracle on Demand, every customer required at least 6 machines, test, development, multiple tiers for database and servers, etc. With virtualization cuts that number down to half that or better.
Next step: Make Linux into the Standard OS for the Data Center. He believes Windows will always be the default desktop OS, but the standard Enterprise/Data Center OS should be Linux.
