What is it? Cloud computing refers to the access of computational resources on demand via a computer network. Those resources include computing power, software, data access, storage services, and more. The main benefit of the cloud is convenient, secure access to all your data and applications anywhere you have an Internet connection. Have you ever used Google Docs? Or stored photos on sites like Flickr or Photobucket? Then you’re already using the cloud.
The Four Flavors of Clouds Several varieties of clouds exist, each with their own features and purposes.
Public Cloud – A public cloud’s infrastructure is made available to the general public or a large industry group and is owned by a cloud services provider.
Private Cloud – The infrastructure of a private cloud is operated solely for an organization. Sometimes, the organization manages the cloud directly. Other times, a third-party handles operations, in which case it’s referred to as a Hosted Private Cloud. A private cloud may exist either on-premises or off.
Community Cloud – A community cloud’s infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). Like private clouds, it may be managed by the organizations or a third-party and may exist on-premises or off-premises. Examples include Google Gov cloud and clouds for educational institutions.
Hybrid Cloud – Finally, a hybrid cloud consists of two or more clouds (private, public, or community) that remain separate entities but are bound together by a standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds). Hybrid clouds exist for purposes of handling high traffic, load balancing, intensive processing, and more.
