Cloud Computing

Cloud computing is combination of the usage of 'computation' and 'cloud'. Cloud computing is the process of making computation work structure with LAN network and globally (by internet) where it can be saved, accessed, edited by numerous people at the same time. 

Cloud is a metaphor from internet, like the cloud that we usually see, cloud is sometimes pictured as computer system. In cloud computing, cloud is a service that can be easily accessed through the internet, so user can access it without even knowing what inside that cloud.

Benefits of cloud computing
1. It can easily stored information and data in no time.
2. Everyone that allowed can easily access it too so it is suitable for long distance meeting.
3. Eliminates the capital expenses of buying hardware.
4. No limit in processor, harddisk, and memory capacity.
5. No limit in number of servers running in the background.

Types of cloud computing

• Private cloud (used exclusively by a single business or organization ). A private cloud can be physically located on the company’s database. Some companies also pay third-party service providers to host their private cloud. A private cloud is maintained in a private network.
• Public cloud ( owned and operated by a third-party cloud service providers ) delivers their computing resources like servers and storage over the internet. Using public cloud, all hardwares, softwares and other supporting data are owned and managed by the cloud provider. Accessing these services require a web browser. Example : Microsoft Azure.
• Hybrid cloud ( combination of public and private clouds ) bound together by technology that allows data and applications to be shared between them. By allowing data and applications to move between private and public clouds, a hybrid cloud have greater flexibility, more deployment options and helps optimize existing infrastructure, security and compliance.
• Community cloud ( share infrastructure between several organizations from a specific community with common concerns (security, compliance, jurisdiction, etc.)) managed internally or by a third-party, and either hosted internally or externally. The costs are spread over fewer users than a public cloud (but more than a private cloud), so only some of the cost savings potential of cloud computing are realized.
