Future of cloud computing

TL;DR: This paper explains the Market growth of cloud computing, Benefit, future of Cloud Computing technology, aspect of current Cloud Computing Scenario, and proposes some future possibility of Cloud computing.

Abstract: Today almost everyone talking about“Cloud Computing” whoever belongs to technology world? The term refers to computing capabilities provided to organizations that operate over the Internet. Businesses and governments are using “the cloud” to provide more and more services as it allows for greater flexibility, efficiency and lower costs. Whether data or software sits on an organization’s own computers or on a cloud service provider’s computers, online services like web-hosted e-mail, document sharing sites and social networking will operate in much the same way they do today. For delivering the vision of Cloud computing, this paper explains the Market growth of cloud computing, Benefit, future of Cloud Computing technology. We would summarize aspect of current Cloud Computing Scenario. We would pay much attention on future aspects like Secure, fast, real time access. We would propose some future possibility of Cloud Computing. Keyword:Cloud Computing, Computing,Virtualization, latest computing paradigm. I.INTRODUCTION Today mostly people use internet services for their work. Cloud computing is a general term for anything that involves delivering hosted services over the Internet. It is a system whereby software programs and storage space can be accessed via the Internet. We can save our data on internet with the help of Cloud Computing. With help of Cloud Computing user can access number of server and as much as application.it provide a fast access platform to user. Cloud computing evolved from the knowledge and experience of managed services, Internet services, application service providers. End users access cloud-based applications through a web browser or a light-weight desktop or mobile app while the business software and user's data are stored on servers at aremote location. Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, Servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction II.CLOUD COMPUTING CONCEPT Cloud computing is way of computing in which resources, software, platforms etc. are provided to the users on request over the world wide network. A) Need of Cloud Computing Traditional business applications have always been very complicated and expensive. The amount and variety of hardware and software required to run them are daunting. We need a whole team of experts to install, configure, test, run, secure, and update them. With cloud computing, you eliminate those headaches because you’re not managing hardware and software—that’s the responsibility of an experienced vendor. The shared infrastructure means it works like a utility. You only pay for what you need, upgrades are automatic, and scaling up or down is easy. As cloud computing grows in popularity, thousands of companies are simply rebranding their non-cloud products and services as “cloud computing.” Cloud computing offers a variety of ways for businesses to increase their IT capacity or functionality without having to add infrastructure, personnel, and software. B) Deployment types of Cloud 1) Private Cloud: Private Cloud are ownedby the respective enterprise or leased for exclusive use by a single organization. Private clouds are of two types: On-premise private clouds and externally hosted private clouds. Example: eBay. 2) Public Cloud:-public Cloud isprovisioned to the general public. Application is hosted on the Hosting Providers location (Vendors). The computing infrastructure is shared between any organizations. Example: Amazon, Google Apps, Windows Azure.

It provides the Cloud infrastructure to group of organizations. Community clouds show some overlap with GRIDs technology. 4) Hybrid Cloud: -Hybrid cloud is anycombination Public and private cloud infrastructures so as to achieve a maximum of cost reduction through outsourcing whilst maintaining the desired degree of control. IBM uses such type of Cloud. 5) Meta Cloud:Meta Cloud incorporatesmultiple cloud infrastructures to allow for the provisioning of meta-services across boundaries and layers. It differs from Hybrid Cloud because it is independent of the underlying deployment types. C) The Categories of Cloud Computing Services Normally Cloud Computing services divide in to following 4 categories:1) Infrastructure-as-a-Service (IaaS):-CloudProviders offering Infrastructure as a Service tout datacenter space, and servers; as well as network equipment such as routers/switches and software for businesses. In essence, you rent a physical server or server colocation; you can use it as per requirement. Examples: Amazon S3, SQL Azure. 2) Platform-as-a-Service(Paas):Provisioning a full hardware architecture and software framework to allow applications to run is the essence of Platform-as-a-Service. Their developers can write their code regardless of the OS behind it. Platform solution, including application development, interface and database, storage, test and so on, available to subscribers on a hosted platform remotely. Examples: Force.com, Google App Engine, Windows Azure (Platform). 3) Software-as-a-Service(SaaS):-Software-as-a-Service is the process of provisioning commercially available software but giving access over the net. The customer doesn’t have to think about software licenses, because that is handled by the service provider. The provider also handles upgrades, patches, or bug fixes. Examples: Google Docs, Sales force CRM, SAP Business by Design. 4) Development-as-a-service (DaaS):Development as a service is web based, community shared development tools. This is equivalents to locally installed development tools in the traditional (nonCloud Computing) delivery of development tools. Apart from these basic 4 services, other services commonly known as*aaS (Everything as a Service). Cloud computing use as below mention services also:1) Storage as a Service: It provides theability to use storage that physically exists in a remote site. 2) Database as a Service: -it provides theAbility to use the services of a database hosted remotely, sharing it with others. It saves user money which he may use for purchase hardware and software International Journal of Latest Trends in Engineering and Technology (IJLTET) Vol. 2 Issue 3 May 2013 73 ISSN: 2278-621X
