How this Term Cloud was Coined?

Definition of Cloud Computing The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted in computer network diagrams and is an abstraction for the complex infrastructure it conceals.

Definition of Cloud Computing Cloud Computing is a model for enabling convenient on demand network access to shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. – NIST

Cloud Computing is a general term used to describe a new class of network based computing that takes place over the Internet:  basically a step on from Utility Computing  a collection/group of integrated and networked hardware, software and Internet infrastructure (called a platform).  Using the Internet for communication and transport provides hardware, software and networking services to clients.

Cloud Computing is a internet based computing, whereby shared resources, software and information are provided to users on computers and other devices like electricity grid.

Cloud Computing can be defined as “a type of parallel and distributed system consisting of a collection of interconnected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources based on service level agreements established through negotiation between the service providers and consumers.”

Definition of Cloud Computing Cloud computing is the new revolution where the user can use anytime, any where, any amount of resource and pay for it as per usage. For it sky is the limit……:Dr.Mayank Aggarwal. Cloud Computing is a technology which enables users to access the resources of the computer by just subscribing them without actually buying them. ……:Dr.Mayank Aggarwal

Why Cloud Computing

Forrester

Cloud Biz Potential: a trillion $ business/year by 2020? 120? 15% 600? 30% 1000? 50% Buyya’s Guestimate!

Business Daily It predicts that Cloud Computing could reduce the Business expenditures of industries by $625 billion over next five years.

Types Of Cloud

Cloud Deployment Models Private/Enterprise Clouds Cloud model run within a company’s own Data Center / infrastructure for internal and/or partners use. Public/Internet Clouds 3rd party, multi-tenant Cloud infrastructure & services: * available on subscription basis Hybrid/Inter Clouds Mixed usage of private and public Clouds: Leasing public cloud services when private cloud capacity is insufficient

Types Of Cloud Public : Public clouds are made available to the general public by a service provider who hosts the cloud infrastructure. Generally, public cloud providers like Amazon AWS, Microsoft and Google own and operate the infrastructure and offer access over the Internet. With this model, customers have no visibility or control over where the infrastructure is located. Private : Private cloud is cloud infrastructure dedicated to a particular organization. Private clouds allow businesses to host applications in the cloud, while addressing concerns regarding data security and control, which is often lacking in a public cloud environment. It is not shared with other organizations, whether managed internally or by a third-party, and it can be hosted internally or externally.

Continued… There are two variations of private clouds: 1. On-Premise Private Cloud: This type of cloud is hosted within an organizations own facility. A businesses IT department would incur the capital and operational costs for the physical resources with this model. On-Premise Private Clouds are best used for applications that require complete control and configurability of the infrastructure and security. 2.Externally Hosted Private Cloud: Externally hosted private clouds are also exclusively used by one organization, but are hosted by a third party specializing in cloud infrastructure. The service provider facilitates an exclusive cloud environment with full guarantee of privacy. This format is recommended for organizations that prefer not to use a public cloud infrastructure due to the risks associated with the sharing of physical resources.

Continued… Hybrid: Hybrid Clouds are a composition of two or more clouds (private, community or public) that remain unique entities but are bound together offering the advantages of multiple deployment models. In a hybrid cloud, you can leverage third party cloud providers in either a full or partial manner; increasing the flexibility of computing. Augmenting a traditional private cloud with the resources of a public cloud can be used to manage any unexpected surges in workload. Here are a couple of situations where a hybrid environment is best:  Your company wants to use a SaaS application but is concerned about security.  Your company offers services that are tailored for different vertical markets. You can use a public cloud to interact with the clients but keep their data secured within a private cloud.  You can provide public cloud to your customers while using a private cloud for internal IT.

Welcome to the New World of Cloud Computing

Why Cloud Computing  Reduction of costs – unlike on-site hosting the price of deploying applications in the cloud can be less due to lower hardware costs from more effective use of physical resources.  Universal access - cloud computing can allow remotely located employees to access applications and work via the internet.  Up to date software - a cloud provider will also be able to upgrade software keeping in mind feedback from previous software releases.

Continue…  Choice of applications. allows flexibility for cloud users to experiment and choose the best option for their needs. Cloud computing also allows a business to use, access and pay only for what they use, with a fast implementation time.  Potential to be greener and more economical - the average amount of energy needed for a computational action carried out in the cloud is far less than the average amount for an on-site deployment.  Flexibility – cloud computing allows users to switch applications easily and rapidly, using the one that suits their needs best.
