Cloud computing could be defined as “a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications”. In simpler words, cloud computing was defined by PC Mag ME Team as storing and accessing data and programs over the Internet instead of your computer's hard drive. The word "cloud" refers to the internet; cloud computing then means computing that is preformed through the internet where data and information are being stored and shared from one place to the other.
A similar concept to cloud computing is using more than one computer that are in the same network to process or solve problems that are difficult to tackle with stand-alone machine.
Cloud computing benefits
- Self-service provisioning: cloud computing provide users with a net of computing resources for any workload.
- Elasticity: companies can control and measure the amount of computing needed and increase it depending on the demand.
- Pay per use: users are able to pay for the resources and workload that the use only.
Cloud computing can be found in three forms: private, public, or hybrid. When its private, this means that the data is being delivered from business’ data center for specific users. This model of cloud computing provides security and control of resources. Where public cloud computing is provided on demand and usually is paid for according to usage. This model of cloud computing is provided for users over the Internet be a third-party. Hybrid cloud combines both previous models; companies for example can use it for their workloads and bursty workload at the same time.
To call it Cloud computing means that you have to be able to get access to your data over the Internet. This makes accessing your data easy from anywhere and everywhere.
On other use of cloud computing is for backup, which is also known as online backup. It means that you store your data on a remote server from your hardware by using a network connection. This is considered to be an affective way to save your data and to create an off-site storage that can be enough for loads of data with minimum hardware requirements. This is one of the ways business can recover from disasters where a data is lost some how, fire, earthquake, etc. Data will remain saved in a remote server.
- If systems can be in risk of hacking, can clouds where information is stored be also in risk?
- What are the limits of cloud computing, is there any storage limits?
- How secure is it?
