  • Since information is stored elsewhere and less processing power and hardrive space is needed end users are now able to buy cheaper and less equipment. This is a financial advantage since you wont need a high-powered (and accordingly high-priced) computer to run cloud computing’s web-based applications. Because the application runs in the cloud, not on the desktop PC, that desktop PC doesn’t need the processing power or hard disk space demanded by traditional desktop software. This way the computers are cheaper and require less hard drive space.(Miller, 2009) When a desktop PC doesn’t have to store and run a ton of software-based applications the computer will run at a more optimal level for the end user. (The apps are run from the cloud, instead.) With fewer bloated programs hogging the computer’s memory, users will see better performance from their PCs. Start up and all functions of the computer will be faster since there are not as many programs taking up the computers memory. (Miller, 2009) Cloud computing greatly reduces both hardware and software maintenance for organizations of all sizes. With less hardware (fewer servers, less PC’s) necessary in the organization, maintenance costs are immediately lowered. With software maintenance, all of the applications are based on other servers so there is no need for the IT to maintain the applications. You will also lower cost of installing the the applications since they will be based elsewhere. As well as gain the ability to only install applications and software on the computers that need it thus lowering licensing cost. (Miller, 2009) Another software-related advantage to cloud computing is that users are no longer faced with the choice between obsolete software and high upgrade costs. When the app is web-based, updates happen automatically and are available the next time the user logs in to the cloud. Whenever you access a web-based application, you’re getting the latest version—without needing to pay for or download an upgrade (Miller, 2009) Users can access the information they need from anywhere that has an internet connection since the information they need is stored out on the internet. This is very user friendly for people that travel a lot, telecommuters, people always on call etc. (Roque, 2009) Servers and datacenters are very expensive for companies to maintain. There are so many cost associated with the rent, upkeep of servers, cooling in the building, etc. The servers alone are expensive but then there is the cost to house and cool them, licensing cost, support cost, etc. With cloud computing this cost is cut significantly since someone else is hosting the server. Paying only for actual usage makes perfect sense for growth-oriented companies, especially startups. Jeff Barr, web services evangelist at Amazon, notes that he can’t name a single failed startup that used the company’s EC2 and S3 platforms for its core infrastructure. Specifically, Amazon charges 10 cents per compute-hour used and 15 cents per gigabyte of storage, Selipsky said. According to research by Forrester, that translates into about $70 to $150 per month for a fully utilized Amazon server, versus the average $400 a month that it costs an enterprise to run a server. (Betelho, 2008) Being able to collaborate on documents is very important to users. Imagine that you, a colleague in your West Coast office, and a consultant in Africa all need to work together on an important document. Before cloud computing, you had to email or snail mail the relevant documents from one user to another, and work on them sequentially. Not so with cloud computing. Now each of you can access the project’s documents simultaneously; the edits one user makes are automatically reflected in what the other users see onscreen. It’s all possible, of course, because the documents are hosted in the cloud, not on any of your individual computers. This helps with projects being completed faster as well as allowing people to work in different regions together without travel. (Miller, 2009) With cloud technology you only pay for the processing power that you need you are not paying for running servers that you are not using. If you hit peak times then you will simply pay for more server space instead of having those servers running all of the time. (Brown, 2008) Another good thing about cloud computing is how fast and easy it is to pull in resources from other servers to improve the performance of an application or website. This is great for companies looking to scale. Let’s say your site is slammed with traffic after a major announcement. With the cloud, you can simply deploy a few more servers to handle the load until the storm passes — and then draw back down later to keep costs under control. (Fisher, 2008)
  • The number one issue voiced by CIO’s has been around the issue of security. Sensitive company information will be stored in an area that is shared by everyone which includes company competitors. There is concern as to how well this data can be protected and how comfortable companies are with allowing sensitive documents outside of their control. (Krill, 2009). Some companies have to abide by certain laws to which requires them to keep information inside company walls and fire walls. This would prohibit companies from allowing this information outside. (Higginbotham, 2008) While it is a good thing to be able to access your information wherever there is an internet connection internet connection is not always guaranteed. If you have your information out in a cloud and can not establish an internet connection then you are out of luck until your internet is either back in service or you can go somewhere to find the internet. (Roque, 2009) Each service only allows users to use one platform or host and all the companies that have cloud technology currently use different platforms. This would require companies and users to have multiple clouds which could be a disaster for companies with data in different places. This also becomes an issue when trying to transfer information from one cloud to another. Some clouds do not support information that has been stored on another cloud. (Krill, 2009) Information is stored on servers all around the globe and some potential problems that could arise out of this are different national laws for information. One example that was given states that Canada is worried about storing data on servers based in the United States because under the U.S. Patriot act it can be accessed by the government. Big companies are cautious and conservative and with so much information it will take companies a while to conform to this new technology. The speed that these virtual servers sometimes run at when processing is sometimes much slower than physical servers. (Miller, 2009
