CLOUD COMPUTING

The terms "cloud computing" and "working in the cloud" refer to performing computer tasks using services delivered entirely over the Internet (The "cloud" refers to the Internet and was inspired by technical flow charts and diagrams, which tend to use a cloud symbol to represent the Internet.)

What is cloud computing?

“A basic definition of cloud Computing is the use of the Internet for the task you perform on your computer.”

Examples of cloud computing1:e-mail2:you tube3:skytype4:gmail5:social sites

Uses of cloud computing1.help to use application without installing.

2.access any personal file at any computer with the internet access.

3.this technology allow much more efficient computation by centralizing storage, memory processing and bandwidth.

Working of cloud computingCloud computer works by hosting your information on computers ‘out there’ ‘in the cloud’. The cloud is basically a batch of computers called data centers or servers that hold your information (files,images,videos,etc) and can be located anywhere. You’re working in a cloud because you don’t have to store software or files on your own computer.

Characteristic of cloud computing1:On demand self service: computer services such as email,applications,networks or server services can be provided without requiring human interaction with each service provider.2:Broad network access: cloud capabilities are available over the networks and accessed through the standard mechanism that promote use by heterogeneous thin and thick client platform such as mobile phone,laptops.PDAs.3:Resource pooling: the providers computing resources are pooled together to serve multiple consumers using multiple-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand.

4:Rapid elasticity: cloud service can be rapidly and elastically provisioned ,in some case automatically ,to quickly scale out and rapidly released to quick scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time. 5:Measure service: Cloud computing resource usage can be measured, controlled, and reported providing transparency for both the provider and consumer of the utilized service

PlatformCloud platform services or Platform as a Service (PaaS)" deliver a stack as a service, often consumingcloud infrastructure and sustainingcloud applications. It facilitates deployment of applications without the cost and complexity of buying and managing the under lying hardware and software layers. Computing platform and/or solution

Infrastructurecloud infrastructure services or “infrastructure as a service{laas}”delivers computer infrastructure, typically a platform virtualization environment, as a service. rather than purchasing servers,software,data center space or network equipment client instead by those resources as a fully outsources services…..

ApplicationCloud application services or "Software as a Service(SaaS)" deliver software as a service over the Internet, eliminating the need to install and run the application on the customer's own computers and simplifying maintenance and support.

Types of cloud computing1.Public cloud: Public cloud or external cloud is a metered service similar to public utility provided by the vendors via web applications or web services where the location of the infrastructure is invisible to the customers and it is shared between the organizations. The numbers of small and medium sized companies acquiring external cloud are rising for its tariff lower than the private cloud.2.Private cloud: Private cloud or internal cloud is a private network in the cloud externally or within the premises where the customers do not share their with other organization.

expensive and more secure than pubic cloud.3.Hybrid cloud: hybrid cloud is the combination of both public and private cloud based upon the criticality of applications used where the organizations may have multiple public and private providers.4.Community cloud: Community cloud is a network shared by the same type of organizations. The National Institute of Standards and Technology (NIST) say Community cloud is a cloud infrastructure which is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, and policy and compliance considerations). It may be managed by the organizations or a third party and may exist on premise or off premise.

Advantages of cloud computing1:cost efficient: cloud computing is probably the most cost efficient to use,maintane and upgrade Traditional desktop software costs companies a lot in terms of finance. Adding up the licensing fees for multiple users can prove to be very expensive for the establishment concern.2:Almost unlimited storage: storing information in the cloud give you almost unlimited capacity. Hence you no need to worry about running out of storage space and increasing current storage availability3:Backup and recovery: since all your data stored in cloud , backing it up and restoring is same is relatively much easier than storing on the same physical device.

4:automatic software intigration:In the cloud, software integration is usually something that occurs automatically. This means that you do not need to take additional efforts to customize and integrate your applications as per your preferences. This aspect usually takes care of itself. Not only that, cloud computing allows you to customize your options with great ease.5:Easy access to information: once you register yourself to cloud, you can access the information from anywhere, where there is an internet connection.

Disadvantages of cloud computing1:security & privacy:The biggest concerns about cloud computing are security and privacy. Users might not be comfortable handing over their data to a third party. This is an even greater concern when it comes to companies that wish to keep their sensitive information on cloud servers.2.Dependency (loss of control):Quality problems with CSP(Cloud Service Providers).No influence on maintenance levels and fix frequency when using cloud services from a CSP.3.Cost:While in the long run, cloud hosting is a lot cheaper than traditional technologies, the fact that it’s

currently new and has to be researched and improved actually makes it more expensive. Data centers have to buy or develop the software that’ll run the cloud, rewire the machines and fix unforeseen problems . This makes their initial cloud offers more expensive.4.Decreased flexibility: this is only a temporary problem (as the others on this list), but current technologies are still in the testing stages, so they don’t really offer the flexibility they promise.5.Knowledge :More and deeper knowledge is required for implementing and managing SLA contracts with CSP’s ,Since all knowledge about the working of the cloud (e.g. hardware, software, virtualization, deployment) is concentrated at the CSP, it is hard to get grip on the CSP.

Conclusion: computing has tremendous potential to benefit businesses, industries, and entire economies, but substantial challenges stand in the way. Our study has taken the first step: defining potential actions for industry and governments to consider in order to accelerate cloud adoption and generate benefits for all stakeholders – individuals, businesses, governments, and society as a whole
