Free Paper presentation PPT Download : “Enterprise level benefits achieved from Cloud Computing”
Have you been hearing a lot about cloud computing lately, have your teachers loaded you with assignments to make cloud computing paper presentations, cloud computing ppts, etc ? Then here is a one stop cloud computing tutorial to not only save your time on trying to access the innumerable cloud computing ppt download links, but also to help you understand what the concept of cloud computing offers.
Cloud Computing: What’s this entire buzz about?
Well, the cloud is something that you have been using for a long time now in the form of the Internet. Then, what is it that is creating this buzz about cloud computing. So here are the cloud computing features that make it the latest sensation promising to shape the entire future of modern computing. The cloud has a trajectory that is hard to plot and a scope that reaches into so many aspects of our daily life that innovation can occur across a broad range. The cloud computing benefits are so immense that it is looked upon as a utility model of computing, with which an application can start small and grow to be enormous overnight.
Cloud Computing Basics:
The use of the word “cloud” tries to describe the two essential concepts, namely
Abstraction : the absolute details of system implementation are hidden from users and developers, the applications are run on physical systems that aren’t specified, and administration of such systems is outsourced to others, data is stored in locations that are unknown, and access by users is ubiquitous.
Virtualization : systems are virtualized by pooling and sharing of resources. Storage can be provided as needed from a centralized infrastructure, costs are assessed and levied with a pay-as-you-use model, multiple tenants are allowed, and resources are scalable with appreciable agility.
Cloud Deployment Models
The cloud deployment models define the purpose of the cloud and the nature of how the cloud is located. There are four basic models one should have some insight on :
Public Deployment : The public cloud infrastructure is available for public use alternatively for a large industry group and is owned by an organization selling cloud services.
Private Deployment : The private cloud’s infrastructure is operated for the exclusive use of an organization. The clouds can be managed by that organization or a third party. Private clouds may be either on- or off-premises.
Hybrid Deployment : A hybrid cloud combines multiple clouds (private, community or public) where those individual clouds retain their unique identities, but are bound together as a unit. A hybrid cloud offers standardized or proprietary access to data and applications, as well as enables and enhances application portability.
Community Deployment : A community cloud is one where the cloud has been organized to serve a common function or purpose of one or several organizations, but they share common concerns such as their mission, policies, security, regulatory compliance needs, and so on. A community cloud may be managed by the constituent organization(s) or by a third party.
Cloud Service Models
Commonly known as the SPI Model, the universally accepted service models are :
Software as a Service : SaaS is a complete operating environment with provisioned applications, management, and the user interfaces.
Platform as a Service: PaaS provides virtual machines, operating systems, applications, services, development frameworks, transactions, and control structures.
Infrastructure as a Service : IaaS provides virtual machines, virtual storage, virtual infrastructure, and other hardware assets as resources that clients can provision.
Cloud Computing Features
The following are an ideal cloud computing model’s features, which will help you to assess the value proposition of a cloud.
Elasticity : You have the ability to right-size resources as required by your application. This feature not only allows you to optimize your system but also capture all the possibilities that come your way.
Scalability : You have access to unlimited computer resources as needed, because the cloud provides infinite resource pool. This feature eliminates the need for careful planning and intelligent provisioning, while enabling batch processing, which greatly speeds up high-processing applications.
Utility model : A pay-as-you-use model matches resources to your need on a continuous basis, which eliminates the wastage of funds and has the most powerful added advantage of shifting risk from the client to the service provider.
Low barrier to entry : Gaining access to systems is cheaper than ever,and only requires for a small investment. This feature offers the cloud users to access globally distributed resources and helps the small ventures by providing the ability to experiment and succeed with minimal risk.
Cloud Computing Benefits
The features of cloud are its very benefits. The advantages of cloud based computing are immense and can vary over a wide range of applications. But, this doesnt mean that it’s a complete recipe for a successful business. The cloud provides On-demand self-service, Broad network access, Resource pooling, Rapid elasticity, Lower costs, Outsourced IT management, Ease of utilization, Quality of Service, Reliability, Measured service, Low Barrier to Entry, Simplified maintenance and upgradations. In cloud computing, anyone can be a giant at any time. Cloud computing is not a panacea, however. In many instances, cloud computing doesn’t work well for particular applications, but the instances are rare and this very long list of benefits should make it obvious why so many people are excited about the idea of cloud computing.
