CLOUD COMPUTING DISRUPTING IMPACTS ON
INFORMATION TECHNOLOGY (IT) SECTORS
Cloud computing has been identified as one of the ten mostdisruptive technologies by Gartner in 2008 .It aims to provide an enterprise datacenter where all capital riskof owning the infrastructure is taken by cloud provider. Cloudprovider computing resources are massive and aims to provide
complete IT support service across internet.Cloud computing is offered by Google App Engine providingapplication componentas service, Amazon EC2 offers virtualinfrastructure as service and Microsoft Azure has set upsoftware platform as service .Cloud computing architecture is based on service orientedarchitecture with multiple layers (clients, service, application,platform, storage and infrastructure).The business drivers and dampers are numerous and is set todisrupt IT industry. IT sectors are mainly business intelligence,CRM, designated software, internet, Knowledge management ,IT management, storage and data system.

is a computing model in whichcomputing resources such as storagespace and processing power can beremotely managed by a third partyand sold to anyone at a priceproportional to the amount of
computing resources desired.

Cloud computing will change the economics of BI by making availablethe hardware, networking, security and software needed to create datamarts and data warehouses on demand with a pay-as-you-go approach
to usage and licensing.More and more businesses are turning to analytic applications toprovide critical business insights achieving higher ROI, betterunderstanding of the competitive landscape, improving product andservice quality,The BI platform is expected to grow by 7.9% in the cloudthrough 2012(according to Gartner).

place in the CRM market? Present trend is the on demand CRM
shall overtake on premise CRM.

While traditional ERP(Enterprise Resource Planning) systems tend to bemonolithic in operation and scale, cloud-based models have the opportunity to
be much more flexible in terms of implementation and network scaling, whichimpact overall total cost of ownership. Armitives current 10 customers hadtheir implementations up and running in an average eight weeks, which isfairly typical of this technology. Cloud based production chain is yet to findproper foothold

If you're an IT manager, cloud computing will fundamentally change yourjob, "With services, we are leaving the hardware world," Stern said. He
meant that system administrators will monitor the network and not itshardware components. "We still need sysadmins but we don't need themrunning around the datacenter with a socket wrench," he said. "Instead,they will use telemetry and tools to assess capacity, security, andperformance."

with cloud storage, data resides on the Web located across storage systemsCloud-storage providers balance server loads and move data among variousdata centers Cloud-storage users typically don't know where their data isstored at any given time..
Storage clouds at a glanceAmazon Simple Storage Service (S3) Available since March 2006Monthly fee: 15 cents per gigabyte of storageAdditional fees: 10 cents to 18 cents per gigabyte for data transfers

The 1 millionth server in the cloud thatsbeen launched, managed and automated byRightScale. 1 million servers. Thats quite a
milestone .why its significant?
It presents more undeniable evidence thatits no longer a question of whether or notcloud computing will become a major forcefor change in IT its only a question of
how fast and where first (e mail from RightScale Inc of Amazon EC2 on 20 March 2010)
