CLOUD COMPUTING
The ‘cloud’ is a true buzzword, but what is it. How does it impact what you do? Is it anything really new? Cloud computing is a general expression for the delivery computing services—servers, storage, software, networking, analytics, database. And moreover the Internet (“the cloud”). Cloud computing enables companies to use a computer resource, such as a virtual machine, storage space or an application, as a utility. Just like electricity — rather than having to build and maintain computing infrastructures in-house.
Cloud Computing Standards:
The standards are not fully defined at present time for linking the computer systems and the software needed to make cloud computing job. Due to which, many companies have to define their own cloud computing technologies. Cloud computing systems obtainable by companies, like IBM’s “Blue Cloud” technologies, for example, are based on open standards and open source software. Due to which computers are connected together that are used to deliver Web 2.0 capabilities like mobile commerce.
Cloud Computing services can be:
Public cloud:-
In the public cloud model, a third-party supplier delivers the cloud service over the internet. Public cloud services are typically sold, by the minute or hour, on demand. Consumers only pay for the CPU cycles, storage space or bandwidth they consume. Companies, that give rapid access over a public network to inexpensive computing resources, own as well as operate public clouds. With public cloud services, customers don’t need to purchase software, hardware or supporting infrastructure, which is owned and managed by providers.
Private cloud:-
A private cloud is an infrastructure operated solely for a single organization. It may be managed internally or by a third-party and hosted either externally or internally. Business’ data center delivers private cloud services to internal users. This model offers versatility, flexibility, and convenience while preserving the management, control, and security common to local data centers. Private clouds can take benefit of cloud’s efficiencies, while providing more control of resources and steering clear of multi-tenancy.
Hybrid cloud:-
Hybrid cloud is a mixture of public cloud services and on-premises private cloud — with orchestration and automation among the two. Companies can execute mission-critical workloads or sensitive applications on the private cloud as using the public cloud for bursting workloads that must scale on demand. The objective of hybrid cloud is to create a unified, automated, scalable environment. An environment that takes benefit of all that a public cloud infrastructure can give while still maintaining control over mission-critical data. A hybrid cloud uses a private cloud organization combined with the planned integration and use of public cloud services.
Common Cloud Examples:
The lines between local computing and cloud computing sometimes get very blurry. So, the cloud is part of almost everything on our computers these days. You can easily have a local part of the software that utilizes a form of cloud computing for storage space. Microsoft also offers a set of Office Online, Web-based apps. They are Internet-only versions of PowerPoint, Word, Excel and OneNote which can be accessed using your Web browser without installing anything. That makes them a version of cloud computing.
