Forecast, Mostly Cloudy Overview Of How Federal It Is Moving Toward Cloud .puting-jinshen

.puters-and-Technology Nextgov(dot).’s article Forecast: Mostly Cloudy provides an excellent overview of how federal IT is moving toward cloud .puting. While the discussion focuses on the government’s adoption of public clouds and private clouds, the reasons, benefits and savings equally apply to business. Federal CIO Vivek Kundra has been promoting cloud .puting, shifting the culture of federal IT to focus on the applications that are running rather than the physical servers that run the applications. He has encouraged a new way of thinking for agency CIOs, encouraging them to define what’s needed in uptime, availability and performance rather than defining needs from a pure hardware perspective. Overprovisioning in hardware (data centers typically operate at less than 30% of capacity), physical space, energy and .puting power is greatly reduced by moving to the cloud. Federal IT managers have already begun consolidating data centers and virtualizing servers, storage and desktops. Some, like DISA in the example below, are even ramping up their data centers to operate as private clouds that offer services to other agencies and charge based on equipment and application use. Access. The GSA is creating an electronic storefront featuring software-as-a-service and infrastructure-as-a-service vendors that have contracts with the GSA. The site will be a one-stop shop for cloud .puting services and should be ready by the end of the year, according to Casey Coleman, CIO at the GSA. She predicts agencies will use the cloud for low-risk applications and estimates that 40 – 50% of all federal IT applications fall in the low-risk category. Reliability: There’s a great summary of how the VA has virtualized about 15% of its servers to speed disaster recovery and improve performance and availability. In addition to freeing up data center floor space and and slashing energy costs, the VA has improved customer service by keeping .puters up and running. Virtualization allows them to dynamically manage server performance and bring on additional resources as needed. "If there’s a 70 percent chance that a server will go down, we have it automated to spin up another server so we can move customer service to a whole new level." Jeffrey Lush, Executive CTO for Enterprise Infrastructure Engineering, VA Office of Information and Technology Private Clouds. The Defense Information Systems Agency (DISA) is leading government agencies in developing private cloud architecture. DISA purchases server capacity on an on-demand basis, no longer using capital dollars or going through the two-year procurement cycles for hardware. DISA operates like an IT service provider, recovering all its costs from its military customers and benchmarking its services against .mercial industry. Virtualization speeds up the process for standing up a new server to two hours, down from up to two years in some instances. (Two years is not a typo! And you thought you had it bad.) Utilization is over 50%, up from 3 to 5% before virtualizing. Rapid Adoption Anticipated. Like other new technologies, as users be.e .fortable with IT as a service, others quickly follow suit and adoption soars. A great example is the House of Representatives, which put all newly elected members on a virtual server architecture in the main data center. They didn’t have to buy hardware and software, so their costs dropped. They immediately signed up 57 offices, then 85 – another 200 offices are waiting to be connected. This was the House’s second major virtualization project; in 2007 it consolidated 200 test and development servers to 20, saving floor space in the data center that was running out. Four years ago they used 490,000 watts of electricity per hour. Today, it uses 125,000 watts an hour. "Not only is it green, but it offers a better security posture for them and it saves money in their individual accounts." Jack Nichols, Director of Enterprise Operations, US House of Representatives Desktop virtualization is up next in the House. It’s expected to improve information security at congressional offices and provide enhanced mobility for users who have offices in Washington as well as remote offices in their districts. Users will be able to access their own unique workstation wherever they are and it will be easier for IT to deploy new applications more rapidly. About the Author: 相关的主题文章:
