Cloud Computing

Editor's Notes

• #2: Good morning, I am going to explain what is cloud computing and how it can help us improve and achieve better cost management
• #3: Cloud refers to a network over the internet. It derives its name from the time clouds were used to represent telephone networks and the internet in computer networks later on. Clouds often appear as single points of access for consumers' computing needs. This causes centralization of data and gives mobility and versatility to the users of cloud services.
• #5: The users pay only for the services they use or on a timely basis This gives cloud computing an advantages as the user pays for only for what he uses and hence allows to save huge costs. It is like Gmail, use when you want and where you want. So you don’t need to store what you need. All you need is browser and internet connectivity.
• #6: The primary layer is the Client consists of computer hardware or software. the Application /Platform/Infrastructure forms the secondary layer. The server stands at the core layer and is specifically designed for delivery in the cloud.
• #7: There is only one versatile application provided by the provider which in turn saves the cost for both the provider and the consumer. The users pays only for the services they use(Such as Electricity) or on a timely basis(Such as club membership). This gives cloud computing an advantages as the user pays for only for what he uses and hence allows to save huge costs for the consumer.
• #8: These are the various services available in the cloud market Cloud Operating Systems Online Storage Online office suites Cloud hosting Online sales management over the cloud Online CRM Cloud collaboration Online app development Email Services Instant messaging services
• #9: Small and Medium Enterprises(SMEs) are getting increasingly associated with Cloud Computing as they cannot justify or afford the large capital expenditure of IT. SMEs in emerging market can be benefited by established infrastructure of provider and inexpensive models of management.
• #10: The folowing are the kind of services: Software as a Service(SaaS) is providing all the features of a sophisticated software, but through a browser , not a locally installed application. SaaS eliminates worries about app servers, storage, application development and related, common concerns of IT. The best examples are Salesforce.com, Google’s Docs
• #11: Platform As a service(PaaS) is about providing virtualized servers and allowing users to run and develop applications on them without having to worry about maintaining the operating system and processing capabilities. Examples Microsoft Azure & Salesforce’s Force.com Infrastructure As a service (IaaS) aims to replace the need of a data centre. It provides cluster of networks, storages, and servers . Example Amazon’s Elastic Compute Cloud [EC2].
• #12: Services are provided by the extensive use of internet and networking. The user subscribes only to the services which he needs. Whenever the user needs to change the quantum of services he can request the service provider to provoke or revoke a particular service. Payment is usually made on a pay as you use basis i.e. either on utility basis or on a timely basis. That is the ser need not to pay for the processing capability which he doesn’t need.
• #13: Infrastructure as a services are Windows live-Skydrive Amazon EC2 Chatter Platform as a Service Microsoft Azure Salesforce’s Force.com eyeOS’s web app development Software as a services Google Docs and Gmail VoIP services from Skype IM service from AOL
• #16: A virtual private network (VPN) is a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (e.g., the Internet) instead of by physical wires.
• #17: An enterprise private network is a network built by an enterprise to interconnect various company sites, e.g., production sites, head offices, remote offices, shops, in order to share computer resources.
• #18: Cost Saving Both for the service provider and consumer deploying the cloud is a profitable issue. Security Because of centralization providers are able to use security features that many users are not able to afford. Metering means the usage is measureable on a per client or per user basis. Multi tenancy enables sharing of resources and costs across a large pool of users. Peak-load capacity increases  Device and location independence enable users to access systems using a web browser regardless of their location or what device they are using (e.g., PC, mobile)
• #19: Privacy privacy over the cloud may be compromised as the data crucial to the organization is stored outside the organization Compliance users may have to adopt community or hybrid deployment modes which are typically more expensive and may offer restricted benefits. Adaptability as there is a single app provided by the provider it may not be perfectly suitable for the consumer’s need. Connectivity poor connectivity to the provider may lead to inefficiency on the end of consumer.
• #23: Thank you for listening me. Hope you a nice day.
