With rapid evolution, you cannot escape the cloud – it enables you build solutions with new platforms, and use new infrastructure to support faster delivery of information and services.
This term is bandied around a lot. It basically refers to a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. Different services — such as servers, storage and applications — are delivered to an organization’s computers and devices through the Internet.
Some of the cloud classes are outlined below.
Private cloud is cloud infrastructure operated solely for a single organization, whether managed internally or by a third-party, and hosted either internally or externally.
Undertaking a private cloud project requires a significant level and degree of engagement to virtualize the business environment, and requires the organization to reevaluate decisions about existing resources.
A cloud is called a “public cloud” when the services are rendered over a network that is open for public use. Public cloud services may be free.
Technically there may be little or no difference between public and private cloud architecture, however, security consideration may be substantially different for services (applications, storage, and other resources) that are made available by a service provider for a public audience and when communication is effected over a non-trusted network.
Hybrid cloud is a composition of two or more clouds (private, community or public) that remain distinct entities but are bound together, offering the benefits of multiple deployment models. Hybrid cloud can also mean the ability to connect collocation, managed and/or dedicated services with cloud resources. A hybrid cloud service crosses isolation and provider boundaries so that it can’t be simply put in one category of private, public, or community cloud service. It allows one to extend either the capacity or the capability of a cloud service, by aggregation, integration or customization with another cloud service.
