![Private Clouds
Private cloud is infrastructure operated
solely for a single
organization, whether managed
internally or by a third-party and
hosted internally or externally.
They have attracted criticism because
users "still have to buy, build, and
manage them" and thus do not benefit
from lower up-front capital costs and
less hands-on management, essentially
"[lacking] the economic model that
makes cloud computing such an
intriguing concept".](https://image.slidesharecdn.com/whatiscloud-120722002719-phpapp02/75/What-is-cloud-14-2048.jpg)

What is cloud ?

- 2. The cloudis a computing service that charges you based only on the amount of computing resources we use. Pay as you go….
- 3. Cloud computing isa 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 supports them
- 4. What Is CloudComputing?? Broadly, it is combination of three Computing concepts : Grid Computing-Cluster of loosely coupled computers for a common cause Utility Computing-Packaging of computer resources as a metered Service Autonomic Computing-Capable of self management

Cloud architecture, thesystems architecture of the software systems involved in the delivery of cloud computing, typically involves multiple cloud components communicating with each other over a loose coupling mechanism such as a messaging queue. Cloud engineering is the application of engineering disciplines to cloud computing. It brings a systematic approach to the high level concerns of commercialization, standardization, and governance in developing, operating and maintaining cloud computing systems. It is a multidisciplinary method encompassing contributions from diverse areas such as systems, software, web, performance, information, security, platform, risk, and quality engineering.

- 10. Software as aService • Software as a service features a complete application offered as a service on demand. • A single instance of the software runs on the cloud and services multiple end users or client organizations. • Eg: salesforce.com , Google Apps Platform as a Service • Platform as a service encapsulates a layer of software and provides it as a service that can be used to build higher-level services. Two Perspectives for Platform as a Service 1. Producer:- Someone producing Platform as a Service might produce a platform by integrating an OS, middleware, application software, and even a development environment that is then provided to a customer as a service.
- 11. 2.Consumer:- Someone using Process as a Service would see an encapsulated service that is presented to them through an API. The customer interacts with the platform through the API, and the platform does what is necessary to manage and scale itself to provide a given level of service Infrastructure as a Service • “Infrastructure as a service “delivers basic storage and computing capabilities as standardized services over the network.

- 13. Public Clouds A publiccloud is one based on the standard cloud computing model, in which a service provider makes resources, such as applications and storage, available to the general public over the Internet. Public cloud services may be free or offered on a pay-per-usage model.
- 14. Private Clouds Private cloudis infrastructure operated solely for a single organization, whether managed internally or by a third-party and hosted internally or externally. They have attracted criticism because users "still have to buy, build, and manage them" and thus do not benefit from lower up-front capital costs and less hands-on management, essentially "[lacking] the economic model that makes cloud computing such an intriguing concept".
- 15. Hybrid Clouds •Hybrid cloudis a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together, offering the benefits of multiple deployment models. It can also be defined as multiple cloud systems that are connected in a way that allows programs and data to be moved easily from one deployment system to another.

The serviceallows users to store data such as music files on remote computer servers for download to multiple devices such as iOS-based devices, and personal computers running Mac OS X or Microsoft Windows. It also replaces Apple's MobileMe service, acting as a data syncing center for email, contacts, calendars, bookmarks, n otes, to-do lists, and other data. en.wikipedia.org/wiki/ICloud
