Cloud computing ppt
- 2. OUTLINE Introduction History Similar Concepts Characteristics Deployment Models
- 3. INTRODUCTION Cloud computing is shared pools of configurable computer system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet. Cloud computing relies on sharing of resources to achieve economies of scale, similar to a public utility. Third-party clouds enable organizations to focus on their core businesses instead of expending resources on computer infrastructure and maintenance. Note that cloud computing allows companies to avoid or minimize up-front IT infrastructure costs.
- 4. HISTORY Before there was cloud computing, there was Service Oriented Architecture (SOA). While cloud encompasses implementation and application delivery options, SOA is concerned with the foundation underneath that makes it all possible. At first the term “Cloud Computing” was used in Compaq internal document in the year 1996.
- 5. SIMILAR CONCEPTS There are several concepts which are similar to cloud computing and share some similar characteristics: Client-Server-Model Computer Bureau Grid Computing Fog Computing Mainframe Computer Utility Computing Green Computing
- 6. CHARACTERISTICS Agility : organizations may be improved, as cloud computing may increase users' flexibility with re-provisioning, adding, or expanding technological infrastructure resources. Maintenance : of cloud computing applications is easier, because they do not need to be installed on each user's computer and can be accessed from different places. Performance: is monitored by IT experts from the service provider, and consistent and loosely coupled architectures are constructed using web services as the system interface. Reliability: improves with the use of multiple redundant sites, which makes well-designed cloud computing suitable for business continuity and disaster recovery.
- 7. DEPLOYMENT MODELS Hybrid Cloud Public Cloud Private Cloud Other Clouds
- 8. HYBRID CLOUD Hybrid cloud is a composition of two or more clouds (private, community or public) that remain distinct entities but are bound together, offering the benefits of multiple deployment models. Hybrid cloud can also mean the ability to connect collocation, managed and/or dedicated services with cloud resources.
- 9. PUBLIC CLOUD A public cloud renders service over a network that is open for public use. Public cloud services may be free. Technically there may be little or no difference between public and private cloud architecture. Security consideration may be substantially different for services that are made available by a service provider for a public audience and when communication is effected over a non-trusted network
- 10. PRIVATE CLOUD Private cloud is cloud infrastructure operated solely for a single organization, whether managed internally or by a third-party, and hosted either internally or externally. Undertaking a private cloud project requires significant engagement to virtualize the business environment, and requires the organization to re-evaluate decisions about existing resources.
