Most data centres suffer from vertical technology silo obesity, according to enterprise solutions provider Oracle. To get the most benefit from cloud computing, organisations need to adopt a more holistic approach to planning, it said.
"Benefits from cloud computing such as cost savings and operational efficiency are obtained by horizontal rather than vertical pooling of resources on the journey to cloud adoption," said Oracle vice president, product marketing for infrastructure & management, Rex Wang, speaking in Kuala Lumpur on 18 August 2011. "Companies need to move away from silo to holistic thinking."
"On the journey to cloud adoption, there are four paradigm shifts that need to be considered and moved through," said Wang. "First, organisations need to consider how to structure and allocate IT resources; second, to meet the challenge of enhanced application development within an enterprise that manages key business processes; third, to cater and build social media interfaces that allow end-users to better collaborate in a business sense; and the fourth shift is to use IT resources to meet security standards in a cloud environment as well as to more securely manage infrastructure resources."
"For example, in the first paradigm shift the need is to integrate IT resources to move away from vertical stacks or silos to shared horizontal pool of resources," he said. "This pooling or sharing is fundamental to cloud computing, which of course can be supported by Oracle virtualisation technology at a server level. Sharing can also be done at the database or middleware level."
Wang said the second paradigm shift was to build a new model for application development rather than to build every application from scratch within an enterprise. "The IT department within an enterprise could create shared services, which allows a line of business analyst rather than a hardcore developer to build a composite application using a graphical tool from the shared library. This process of application assembly results in an application that can be brought to market faster."
"The third paradigm shift involves creating collaboration models for enterprise similar to the social networking models," he said. "This allows collaboration between colleagues to deliver more effective customer handling."
Security as a service
"The fourth paradigm shift is around security, which is a number one issue for cloud," said Wang. "Traditionally, secure ID management modules are used. However, when leveraging cloud computing, we should move to a service oriented security model. This centralises the management of users along enterprise resources across all applications, for instance with Oracle Identity Management software,"
