CLOUD COMPUTING Ewing Christian Institute of Management and Technology Allahabad presented by Anushree Malviya mca 5 sem
Introduction Cloud: cloud is one of the most important icon of the computer network we use a cloud which denoting a type of network whether is a point to point network. Multipoint network. switching network. Computing: Computing is usually defined as the activity of using and developing computer technology. Cloud computing : Cloud computing is the provision of dynamically scalable and often virtualized resources as a services over the internet Users need not have knowledge of, expertise in, or control over the technology infrastructure in the "cloud" that supports them. Cloud computing represents a major change in how we store information and run applications. Instead of hosting apps and data on an individual desktop computer, everything is hosted in the "cloud"an assemblage of computers and servers accessed via the Internet.
Cloud computing services often provide common business application online that are accessed from a web browser, while the software and data are stored on the servers. The term cloud is used as a metaphor for the Internet The Cloud is a term that borrows from telephony Up to the 1990s, data circuits (including those that carried Internet traffic) were hard-wired between destinations. Subsequently, long-haul telephone companies began offering virtual private network (VPN) service for data communication. The term cloud had already come into commercial use in the early 1990s to refer to large Asynchronous transfer network (ATM) networks. By the turn of the 21st century, the term "cloud computing" began to appear more widely.
Advantages of cloud computing Lower computer cost. Improve performance. Reduce software cost. Instance software updates. Improved document format compatibility. Unlimited storage capability. Increase data reliability. Universal document access. Latest version availability. Easier group collaboration. Device independence.
Comparison with other computing Grid computing Utility computing Automatic computing
Cloud services Software as a services Platform as a services Infrastructure as a services
Cloud providers SaaS providers Run on top of underlying cloud infrastructure platforms CRM, ERP, VoIP, BI, supply chain PaaS providers ERP,DB,XML files, flat files,web services, on-demand apps, SaaS hoster, APIs, load balancing, DNS configuration, storage IaaS providers Proxy for buying servers, software, data center space or network equipment Pay for memory, bandwidth, storage consumed
Remote desktop applications Run on top of underlying cloud infrastructure platforms Web 2.0 interconnectivity and interactivity of web-delivered content New Services exploiting underlying platforms Grid has many definitions Network of computing clusters Resources used in parallel as a virtual super-processor
Types of cloud computing Public cloud Hybrid cloud Private cloud
It provides green open cloud
Architecture of cloud computing Cloud architecture the systems architecture of the software systems involved in the delivery of cloud computing, comprises hardware and software designed by a cloud architect who typically works for a cloud integrator. It typically involves multiple cloud components communicating with each other over application programming interfaces, usually web services.systems architecturesoftware systems application programming interfaces web services Individual users connect to the cloud from their own personal computers or portable devices, over the Internet. To these individual users, the cloud is seen as a single application, device, or document. The hardware in the cloud (and the operating system that manages the hardware connections) is invisible. Cloud services Cloud platform Cloud infrastructure Cloud storage
Research and development Akamai cloud computing Vmword 2009 How stuff provide cloud computing Sales force provide seven standard Azure and force. com Amazon web services Why cloud computing is distinct. User centric interface On demand service provision. Qos guarantee offer. An autonomous system. Scalability and flexibility In 2008 IEEE conference are organized on web services held in Beijing include a panel Cloud computing and it as a services.
To illustrate the definition to form a three layer architecture. (saas,paas, iaas). Function aspect –Hardware as services,Data as services. Enabling technology behind Virtualization technology. Web services and SOA enable services. Some strategies- Microsoft-software plus services IBM-transform through customer implementation. Cisco involving interoperability.
Review and suggestion Cloud computing still has to exist on physical servers. Problem for users: It does leave responsibility of data storage and control in the hands of the provider. Cloud computing has been criticized for limiting the freedom of users and making them dependent on the cloud computing provider Solution: The majority of cloud computing infrastructure, as of 2009, consists of reliable services delivered through data centers and built on servers with different levels of virtualization technologies. The services are accessible anywhere that provides access to networking infrastructure.data centersvirtualization
Changing the way IT resources are consumed In coordination with large technology partners, standards bodies and cloud services providers, VMwares leading technology platform, VMware vSphere, enables you to transform your datacenter into an internal cloud – a pool of virtualized resources within a datacenter – and seamlessly leverage external cloud providers within the private cloud.VMware vSphere
Cloud computing represents a major change in how we store information and run applications. Instead of hosting apps and data on an individual desktop computer, everything is hosted in the "cloud"an assemblage of computers and servers accessed via the Internet. Cloud computing lets you access all your applications and documents from anywhere in the world, freeing you from the confines of the desktop and facilitating wholesale group collaboration.
Conclusion Hence it provide a new kind of computing platform. Its is a heavy deal over distributed and utility computing. Cloud computing provide enormous impact over internet. It gives us a new application programming model technology. Thus cloud computing provide a super-computing power.This cloud of computers extends beyond a single company or enterprise. The applications and data served by the cloud are available to broad group of users, cross-enterprise and cross-platform.
