  15. 15. More benefits <ul><li>Reduced Cost </li></ul><ul><ul><li>Cloud technology is paid incrementally, saving organizations money.  </li></ul></ul><ul><li>Increased Storage </li></ul><ul><ul><li>Organizations can store more data than on private computer systems. </li></ul></ul><ul><li>Highly Automated   </li></ul><ul><ul><li>No longer do IT personnel need to worry about keeping software up to date. </li></ul></ul><ul><li>Flexibility </li></ul><ul><ul><li>Cloud computing offers much more flexibility than past computing methods. </li></ul></ul><ul><li>More Mobility   </li></ul><ul><ul><li>Employees can access information wherever they are, rather than having to remain at their desks. </li></ul></ul><ul><li>Allows IT to Shift Focus </li></ul><ul><ul><li>No longer having to worry about constant server updates and other computing issues, government organizations will be free to concentrate on innovation. </li></ul></ul><ul><li> </li></ul>08/06/09 © Justin Souter 2009
  16. 16. Even more benefits <ul><li>1. Lower up-front costs. </li></ul><ul><ul><li>When introducing a new application, hardware is a significant upfront cost, said Armijo. </li></ul></ul><ul><ul><li>But cloud computing means the IT department can acquire the resources by paying the provider “by-the-drink” while not spending on hardware up front, and “and this allows you to spread that cost over time, and also to really manage that cost.” So, the required 10 servers by application, once successful, can be purchased incrementally. </li></ul></ul><ul><li>2. Faster time to market. </li></ul><ul><ul><li>It typically takes about two to four months to get an application into production, said Armijo, but in the cloud, applications can be deployed and scaled “in hours without changing code.” </li></ul></ul><ul><li>3. Reduced financial risk. </li></ul><ul><ul><li>If the application for whatever reason doesn’t catch on, or its use within the business has a limited time frame, Armijo said the business no longer has to pay for those resources in the cloud. </li></ul></ul>08/06/09 © Justin Souter 2009
  17. 17. Even more benefits #2 <ul><li>4. Lower capital expense. </li></ul><ul><ul><li>Cloud computing leverages commodity hardware, so IT departments can avoid over-provisioning, said Armijo. </li></ul></ul><ul><ul><li>And, while a server may appear only to cost around $5,000, he said “but the reality is there is a lot more capital that goes into putting that [data centre] space in there before you even get the server.” </li></ul></ul><ul><ul><li>Data centre setup is a “huge expense” and enterprises are even running into power and cooling limits within their facilities, he said. </li></ul></ul><ul><li>5. Lower operational expense. </li></ul><ul><ul><li>When application operations are streamlined, IT administrators are not so belaboured with tasks like provisioning and management of servers, he said. </li></ul></ul><ul><li>6. Decreased downtime and costly delays. </li></ul><ul><ul><li>It’s easy to setup business continuity, redundant instances of applications with cloud computing, said Armijo. </li></ul></ul><ul><ul><li>Moreover, he said, cloud service providers, given that is their business, have state-of-the art equipment for power backup and cooling. </li></ul></ul>08/06/09 © Justin Souter 2009
  18. 18. Even more benefits #3 <ul><li>7. Additional services. </li></ul><ul><ul><li>Cloud service providers, too, can offer services that an IT department otherwise wouldn’t be able to afford, said Armijo, like added security measures, redundancy, bandwidth, and staff with cloud expertise. </li></ul></ul><ul><ul><li>The adoption pattern of cloud computing has certainly changed, said Armijo, where at the end of 2007, adopters were those companies one might expect, like Web and software-as-a-service companies, as well a handful enterprises. </li></ul></ul><ul><ul><ul><li> </li></ul></ul></ul><ul><ul><li>But today, 3Tera customers are predominantly enterprises. </li></ul></ul><ul><ul><li>Armijo thinks this is probably due to the unstable economic times and the challenge of having to maintain a large IT resource. </li></ul></ul><ul><ul><li>“ These are folks that have enormous IT budgets and staff, and as the economy starts to soften, they’re the ones that get hit the hardest,” he said.   </li></ul></ul>08/06/09 © Justin Souter 2009
