Cloud Computing and its Classifications
What is Cloud computing?
Cloud computing is an emerging form of web hosting that is proving to be very popular with businesses and organizations that require a high level of uptime from their web hosting service whilst maintaining a high level of security.
Cloud technology allows the reusability of IT resources for storing large databases, developing and hosting complex applications, and expanding computational strength and other services on demand. Reducing or eliminating expenses on large-scale infrastructure and software, coupled with the pay-per-use model, significantly diminishes IT costs.
Cloud computing is usually classified based on location, or on the service that the cloud is offering.
Based on a cloud location, we can classify cloud as:
Public Cloud Computing
Public cloud, in general, is SaaS services offered to users over the internet. The whole computing infrastructure is located on the premises of a cloud computing company that offers the cloud service. It is the IT infrastructure that is used by many companies and services at the same time. It is the most economical option for users in which the service provider bears the expenses of bandwidth and infrastructure. It has limited configurations, and the cost is determined by usage capacity. They offer an easy and affordable way to deploy Web sites and business systems, with high scalability, which in other solutions would be available.
Private Cloud Computing
As the name implies, the private cloud is used by large enterprises to develop and manage their own data centers for particular business and IT operations. A secure IT infrastructure is controlled and operated for the benefit of a single organization. The organization can manage its own private cloud or outsource this task from an external contractor. Infrastructure can be placed either on the premises of the customer or in a data center. The ideal private cloud is the cloud that is deployed in the organization premises, served, and controlled by its employees.
Hybrid Cloud Computing
Is the IT infrastructure using the best qualities of public and private clouds, with the task? A hybrid cloud is the combination of a private and public cloud, providing for more flexibility to businesses while having control over critical operations and assets, coupled with improved flexibility and cost-efficiency. Often this type of cloud is used when an organization has seasonal periods of activity, in other words, once the internal IT infrastructure cannot cope with current challenges, some facilities are transferred to a public cloud (e.g. large amounts of statistical information, which is in its raw form or something that does not represent value for the enterprise), as well as to provide user access to enterprise resources (for private cloud) via a public cloud.
A community cloud is shared between organizations with a common goal or that fit into a specific community (professional community, geographic community, etc.). For example, a community cloud can belong to the government of a single country. Community clouds can be located both on and off the premises.
