Cloud computing allows users to store and access data over the Internet instead of on local hard drives, with promises of reduced costs since the cloud provider handles server maintenance, software updates, and users pay based on usage. However, cloud computing also carries risks such as potential outages preventing access to applications, and sensitive data may need to remain on-site rather than on someone else's machines for security reasons.
Cloud computing overview
- 1. You Pay as you Use
- 2. • Cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet. • Cloud computing promises to cut operational and capital costs.
- 4. • The beauty of cloud computing, as shown in Figure is that another company hosts your application (or suite of applications, for that matter). • This means that they handle the costs of servers, they manage the software updates, and—depending on how you craft your contract—you pay less for the service
- 5. • As with everything in IT, there are pros and cons. Cloud computing is not exempt. Let’s take a quick look at a few areas of potential trouble. The following illustration shows potential points of failure.
- 6. • While an Internet outage or problems with your Internet service provider (ISP) are rare, you may not be able to access your applications and do your work. • There may simply be applications or data that you want located on-site. If you have sensitive or proprietary information, your IT security group may simply mandate that you not store it on someone else’s machines.
