Cloud computing
- 2. What is Cloud ? Cloud Computing Concept. History of Cloud Computing. Characteristics of Cloud Computing. Why Cloud Computing required. Different Issues to Cloud Computing. Types of Cloud Computing deployment. Types of Cloud Computing Services. Different Applications. Future Architecture of cloud computing. Advantage/ Disadvantage of Cloud Computing. Conclusion
- 3. Cloud computing refers to the use and access of multiple server-based computational resources via a digital network (WAN), Internet connection using the world wide web etc. Cloud users may access the servers resources using a computer, notebook, ipad, smart phone, or other device. The cloud is a new business model wrapped around new technologies such as computer virtualization that takes advantages of economies of scale and multi- tenancy to reduce the cost of using information technology resources.
- 4. In cloud computing, application are provided and managed by cloud server and data is also stored remotely in the cloud configuration. Users do not download and install applications on their own device or computer; all processing and storage is maintained by the cloud servers. The on-line services me be offered from a cloud provider or by a private organization. The Cloud computing is in terms of computer, network and its associated technology supports delivering infrastructure such as computing application and storage to customers on demand by any Service provider.
- 5. Cloud computing is a natural evolution of the widespread adoption of virtualization, service-oriented architecture , autonomic, and utility computing. Details are abstracted from end-users, who no longer have need for expertise in or control over, the technology infrastructure “in the cloud” that support them. The actual term “cloud” borrow from telephony in that telecommunication companies, who until the 1990 offered primarily dedicated point to point data circuits, began offering virtual private network (VPN) services with comparable quality of service but at a much lower cost.

- 7. To reduce the IT operations and management costs. Cloud model of software architecture. No Capital expenditure. Can be access from any where.
- 8. Cloud computing may create a dependence on the provider (Google, Amazon) and may make it difficult to move to another platform. Google itself admits that Google App Engine is targeted at consumer applications, not businesses. There’s always the risk that the Cloud provider may change business models or even go out of business.
- 9. Public Cloud Private Cloud Community Cloud Hybrid Cloud Combined Cloud “ But mainly three type of deployment is in use i.e. public, private, hybrid.”
- 11. IaaS (Infrastructure as a Service)- Computer configurations like RAM, CPU, Storage space. PaaS (Platform as a Service)- Computing resources (Ram, CPU, Hard disk drive space), and software such as OS MS windows or Linux, etc. SaaS (Software as a Service)- Microsoft Office, Sage Accounts, Tally, Exchange mailbox, CRM Programs, etc.

- 13. Flexibility Scalability Resilience Security Lower Costs Backed Up Availability
- 15. Software as a Subscription Reduced Software Maintenance Increased Reliability Environmentally Friendly Cost Reduction Portability/Accessibility ______________________________________________________ Bandwidth could bust your budget App performance could suffer Data might not be cloud-worthy Too big to scale
- 16. Cloud Computing is the fastest growing part of IT. Tremendous benefits to customers of all sizes. Cloud services are simpler to acquire and scale up or down. Public clouds work great for some but not all applications. Private clouds offer many benefits for internal applications. Public and private clouds can be used in combination.
