Cloud-computing part 1
- 2. Cloud Computing is internet based computing, where virtual shared servers provide Software, infrastructure, platform, devices and other resources on a pay-as-you-use basis. âWhy do it yourself if you can pay someone to do it for you?â Cloud Computing Session-1
- 3. A pool of highly scalable, abstracted infrastructure, capable of hosting end-customer applications, that is billed by consumption. Cloud Computing Session-1
- 5. Why More Businesses Are Using Cloud Computing Why ? Secure Storage Management Easy Deployment Frees Up Internal Resources Highly Automated Reliability, Scala bility & Sustainability Device & Location Independent Cloud Computing Session-1
- 6. Broad Network Access. On Demand Self Service. Resource Pooling. Measured Service. Rapid Elasticity. Cloud Computing Session-1
- 7. Cloud Computing Architecture Consists of:- 1. Front End: It comprises clientâs device and some application are needed for accessing cloud computing system. 2. Back end: It refers to the cloud itself which may encompass various computer machines, data storage systems and servers. Cloud Computing Session-1

- 9. ï Users select a task or service (either starting an application or opening a document). ï Userâs request goes to the system management, which finds the correct resources and then calls the systemâs appropriate provisioning services. ï These services > Carve out the necessary resources in the cloud > Launch the appropriate web application > Opens the requested document. ï Web application is launched ï Systemâs monitoring functions track the usage of the cloud so that resources are apportioned and attributed to the proper user(s). ï User is charged according to the amount of utilities and resources used. Cloud Computing Session-1
- 10. With cloud storage, data is stored on multiple third-party servers, rather than on the dedicated servers. When storing data, the user sees a virtual serverâthat is, it appears as if the data is stored in a particular place with a specific name. In reality, the userâs data could be stored on any one or more of the computers used to create the cloud. Cloud Computing Session-1

Mainframe Rise of the PC Client Server Architecture Hosted/Co located Environment Start of the Authorization phase Rise in demand and penetration of the personal desktop Emphasis on Networking IT infrastructure Management services provided by 3rd party providers Emergence of the âas aâ Service Paradigm Localized Infrastructure Decentralized computing Demand for bandwidth began to rise Birth of the infrastructure outsourcing Delivery of IaaS,PaaS and Saas services Expensive Birth of the IT services industry Rise in operation expenditure Used for reducing cost & increasing focus on core activities A move from CAPEX to OPEX Introduction of ASP technology Resulted in the creation of large data centers Collaborative solution that cater to real time information model Dot Com revolution Utility Computing Model Pre 1970s 1980s 1990s 200s Beyond 2010 Automation Decision support virtual integration Borderless Technologies and the virtual world Cloud computing Cloud Computing Session-1
- 17. ï Cloud Computing enables a shift from the computer to the user, from applications to tasks, and from isolated data to data that can be accessed from anywhere and shared with anyone. ï The user no longer needs to remember where the data is. All that matters is that the data is in the cloud, and thus immediately available to that user. Cloud Computing Session-1
- 18. âą There are many definitions of cloud services but, the NIST definition is the most widely accepted definition used today. âą Whole system is administered via a central server that is also used for monitoring clientâs demand and traffic ensuring smooth functioning of the system.

Hinweis der Redaktion
- Cloud Computing gets its name as a metaphor for the Internet.Typically , the Internet is represented in network diagrams as a cloud.
- Cloud Computing - cloud services and storage are accessible from anywhere in the world over an Internet connection
- - On demand self services: computer services such as email, applications, network or server service can be provided without requiring human interaction with each service Provider- Broad network access: Cloud Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms such as mobile phones, laptops and PDAs.Resource pooling: The providerâs computing resources are pooled together to serve multiple consumers using multiple-tenant model, - Rapid elasticity: Cloud services can be rapidly and elastically provisioned, in some cases Automatically.Measured service: Cloud computing resource usage can be measured, controlled, and reported providing transparency for both the provider and consumer of the utilised service.
- Clients are , in a cloud computing architecture, the exact same things that they are in a plain ,everyday local area network
- In a simple ,topological sense, a cloud computing solution is made up of several elements like: client,the datacenter and distributed servers.
- Data stored in the cloud is secure from accidental erasure or hardware crashes, because it is duplicated across multiple physical machines.
- Consumption is usually billed on a utility(like phone bills)or subscription(like magazine)models.Easy to maintain as they donât have to be installed on each userâs desktop.
- Some organizations use cloud computing to deliver their corporate intranet. Intranets are used within an organization and are not publicly accessible . However, now intranets are being maintained on the cloud . To access the companyâs private, in-house information, users are having to log on to the intranet by going to a secure public web site.
- Amazon was one of the first companies to offer cloud services to the public.Amazon has its Elastic Compute Cloud (EC2), a web service that provides cloud-based resizable computing capacity for application developers.Google - Whether you want cloud-based word processing (Google Docs), presentation software (Google Presentations),email (Gmail),or calendar/scheduling functionality (Google Calendar), Google has an offering.Microsoft âMicrosoft offers Windows Live suite of web-based applications, as well as the Live Mesh initiative thatâs trying to link together all types of devices, data, and applications in a common cloud-based platform.IBM has established a Cloud Computing Center to deliver cloud services and research to clients.Salesforce.com - CRM software solutions and enterprise cloud computing.
