A Look At Cloud .puting Services-mmhouse

.puters-and-Technology Wikipedia defines cloud .puting as "the use of .puting resources (hardware and software) that are delivered as a service over a network (typically the Internet)." Simply put, cloud .puting is the provision of easy and scalable access to .puting resources and IT services to those who need it. Today there exist different types of cloud .puting services such as Infrastructure as a service (IaaS), Platform as a service (PaaS), Software as a service (SaaS), Storage as a service (STaaS), Security as a service (SECaaS), Data as a service (DaaS), Test environment as a service (TEaaS), Desktop as a service (DaaS), API as a service (APIaaS) and so on. The three most important aspects of cloud .puting are 1. The services are available on demand and these are sold by the hour or the minute 2. The services are flexible and therefore the users can increase or decrease the amount of services 3. The services are fully managed by the provider and therefore no botheration for the users A cloud can be private, public, .munity, or hybrid. Let"s understand the fundamental differences between them. " Private Cloud "" When the cloud infrastructure is operated for a single organization it is known as a private cloud. " Public Cloud "" In this case, the service provider makes the applications, storage, and other resources available to the public. That means the services are sold to anyone on the Internet. " .munity Cloud "" It refers to the cloud infrastructure shared among organizations from a specific .munity. " Hybrid Cloud "" As the name implies, it refers to the .bination of two or more clouds. With this model, users gain from the benefits of multiple cloud models. Today, Virtualization, weak economy, and access to high-speed Internet have made cloud .puting the first choice of almost all enterprises. Though cloud .puting has its share of advantages it also has its share of disadvantages. And the greatest disadvantage of all especially in the case of public cloud is the lack of security. When enterprises move their .puting environments along with their identities, information and infrastructure to the cloud, they must give up some level of control. But for that to happen there is the need of trust in the cloud systems and the providers. This can be possible only if the cloud .puting providers are able to invoke a sense of trust in the enterprise. Hence, it is imperative that in today"s highly .plex and .petitive environment, enterprises collaborate with those service providers who provide public cloud .puting services securely.
