Where Are We on Oracle Grid Implementation?

With the recent economic lull and with many enterprises cutting budgets, everyone is taking a serious look at the management of computing resources and looking for alternate ways to mange them more efficiently. Some enterprises are blessed with more capacity than needed; and these enterprises are evaluating their usage patterns. This is where Grid Computing is definitely becoming a relevant technology.

Many IT industry experts believe that the existing computing resource utilization requires a serious look in terms of use and availability.

It has always been a challenge for many of the enterprises to do accurate capacity planning. Capacity Planning is an elusive target, and always falls short. Grid computing direction gives them new hope and allows them to utilize all the sources as a single pool.

With the widespread availability of the commodity Intel-based servers and growth of blade servers, Grid Computing concept of virtualization is becoming an attractive proposition. Moreover, other factors like availability of storage area networks (SAN), high speed networks, such as Infiniband and Gigabit Ethernet, are able to provide a realistic and cheaper means of building a grid computing environment. Software options like Web Services and adoption of Linux and other open source technologies are helping this movement towards the virtualization of resources.

The 451 Group in its recently released report, Grids 2004: From Rocket Sciences to Business Services writes:

??..the grid computing developments will result commercially viable, mainframe like performance and manageability across distributed systems with in next 12 months?

The 451 group believes there is enough interest and initiative by the leading IT vendors to move Grid Computing into the commercial and business world. Commenting on the growth of the Grid environment and the role of various IT products, their report classifies the Grid related products and services vendors in broader groups. They are as follows:

Tier One Grid vendors - This is a group, which includes vendors like HP, IBM, Microsoft and Sun. These companies have strong momentum and potential to capture Grid Market Share.

Tier Two Grid Vendors - This group contains the IT companies with strong emerging strategies and technologies in Grid Computing. Vendors in this category include Computer Associates, Intel, Oracle, Platform Computing, SGI and Veritas.

Pure-play Grid Vendors - These are emerging vendors with strong presence in specific areas. These companies are further categorized by functionality - grid enablement, file systems, provisioning, application decomposition, CPU scavengers and those offering enhancements to Globus. Vendors in this category include Altair, Avaki, Axceleon, DataSynapse, Ejasent, Enigmatec, Entropia, GridFrastructure, GridIron, GridSystems, GridXpert, Powerllel, Tsunami Research, The Mind Electric and United Devices.

The last category is an interesting group of vendors, which are heavily investing in developing various software solutions that support Grid Computing and its realization. This group of vendors is also undergoing changes with active merger and acquisition activity. Bigger vendors are acquiring these smaller entities to enrich their own Grid offerings.

At the same time, there are some researchers who are very cautious. Despite the attention Grid Computing has received over the last year, according to a recent Nucleus Research survey report,

"only 20 percent of the IT managers said that they had plans to evaluate grid computing technologies over the next six months, with most saying that more research needs to be conducted before they?ll consider it. Even then, only 11 percent of the interviewees knew what problems they?d use grid computing to solve."

Therefore, it would be fair to say that while the buzz of Grid Computing is heard by many, they also feel that we are not prepared to implement readily, though we are moving steadily forward.

In a significant move, Oracle is actively getting involved and is gearing up the products, services and solutions to fit into the emerging Grid Computing arena. Oracle?s addition of grid support to its application server, database, and development tools plays into the company?s strategy of paving the way for the enterprise Grid Computing architecture.
