IBM’s Blue Cloud is a platform for cloud-based computing, expected to be available to customers in the spring of 2008, supporting systems with Power and x86 processors.
“Blue Cloud" will allow corporate data centers to operate more like the Internet, enabling computing across a distributed, globally accessible fabric of resources, rather than on local machines or remote server farms.
It is, along with Amazon's Elastic Compute Cloud, a seminal step towards network-based computing architectures. Sun Microsystems was ahead of its time in declaring that the "network is the computer." But cloud computing is going to fulfill the prediction.
Call it "software as a service" if you like. The point is that we are nearing an era where resources will be invoked from the computing cloud using a Web browser. Policies still will be needed to authorize use of specific resources, to be sure. But the larger point is that computing, storage and application resources will reside "in the cloud," and be invoked as required by users at the edge of the cloud.
There are all sorts of practical advantages. Distributed or mobile workers can simply invoke their services and information from where they are, using a standard Web browser. Everyone always will have the latest version, the latest patch, the latest version or update.
Computationally intense activities can be handled by clusters of machines designed for such intensity. Storage can be invoked, not carried; used rather than built.
If a developer needs expensive resources, they can be gotten on a sort of "time shared" basis, rather than on a "build your own computing center" basis.
Blue Cloud will be based on open standards and open source software supported by IBM software, systems technology and services.
The interesting speculation is about how cloud computing might change the way enterprises think about their application and storage architectures. Given the massive increase in the scale of IT environments, one wonders how they'll assess the trade-offs between "building data centers" and "renting reources."
Up to this point, the enterprise data center has been the penultimate computing resource. Might the "cloud" surpass even local and networked data centers?
