PRESENTATION ON CLOUD COMPUTING
- 2. INTRODUCTION Cloud computing is a model for enabling convenient, on-demand access to a shared pool of configurable computing resources. Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in third-party data centers. It is a general term used to describe a new class of network based computing that takes place over the Internet, • Basically a step on from Utility Computing • A collection/group of integrated and networked hardware, software and Internet infrastructure, called a platform. • Using the Internet for communication and transport provides hardware, software and networking services to clients.

- 6. TYPES OF SERVICE MODEL Infrastructure as a Service (IaaS) Platform as a Service (PaaS) Software as a Service (SaaS)
- 7. ►This is also known as hardware as a service. ►It is a computing power that you can rent for a limited period of time. ►It allows existing applications to be run on a cloud suppliers hardware. ►Cloud providers offer computers – as physical or more often as virtual machines – raw (block) storage, firewalls, load balancers, and networks.
- 8. ►Gives nice API (Application Programming Interface) and take care of the implementation. ►In the PaaS model, cloud providers deliver a computing platform and/or solution stack typically including operating system, programming language execution environment, database, and web server. ►It is a platform for developers to write and create their own SaaS i.e. applications. ►Usage of it means rapid development at low cost. ►Example: Salesforce.com, Windows Azure etc.
- 9. ►Also known as On-demand Service. ►It is an application that can be accessed from anywhere on the world as long as you can have an computer with an Internet Connection. ►We can access this cloud hosted application without any additional hardware or software. ►Examples : G-mail, Yahoo mail, Hotmail etc. ►Also it can provide security features such as SSL encryption, a cryptographic protocol.
- 10. TYPES OF CLOUD
- 11. 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 a significant level and degree of engagement to virtualize the business environment, and requires the organization to reevaluate decisions about existing resources. When done right, it can improve business, but every step in the project raises security issues that must be addressed to prevent serious vulnerabilities.
- 12. A cloud is called a "public cloud" when the services are rendered 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, however, security consideration may be substantially different for services (applications, storage, and other resources) that are made available by a service provider for a public audience and when communication is effected over a non-trusted network. Generally, public cloud service providers like Amazon AWS, Microsoft and Google own and operate the infrastructure at their data center and access is generally via the Internet.
- 13. MULTI CLOUD Multi cloud is the use of multiple cloud computing services in a single heterogeneous architecture to reduce reliance on single vendors, increase flexibility through choice, mitigate against disasters, etc. It differs from hybrid cloud in that it refers to multiple cloud services, rather than multiple deployment modes.
- 14. 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. Gartner, Inc. defines a hybrid cloud service as a cloud computing service that is composed of some combination of private, public and community cloud services, from different service providers. A hybrid cloud service crosses isolation and provider boundaries so that it can't be simply put in one category of private, public, or community cloud service. It allows one to extend either the capacity or the capability of a cloud service, by aggregation, integration or customization with another cloud service . Varied use cases for hybrid cloud composition exist. For example, an organization may store sensitive client data in house on a private cloud application, but interconnect that application to a business intelligence application provided on a public cloud as a software service
- 15. A community cloud in computing is a collaborative effort in which infrastructure is shared between several organizations from a specific community with common concerns (security, compliance, jurisdiction, etc.), whether managed internally or by a third-party and hosted internally or externally. The costs are spread over fewer users than a public cloud (but more than a private cloud), so only some of the cost savings potential of cloud computing are realized.

- 18. LOWER COMPUTER COSTS You do not need a high-powered and high- priced computer to run cloud computing's web- based applications. Since applications run in the cloud, not on the desktop PC, your desktop PC does not need the processing power or hard disk space demanded by traditional desktop software. When you are using web- based applications, your PC can be less expensive, with a smaller hard disk, less memory, more efficient processor. In fact, your PC in this scenario does not even need a CD or DVD drive, as no software programs have to be loaded and no document files need to be saved.
- 20. INCREASED DATA RELIABILITY Unlike desktop computing, in which if a hard disk crashes and destroy all your valuable data, a computer crashing in the cloud should not affect the storage of your data. If your personal computer crashes, all your data is still out there in the cloud, still accessible. In a world where few individual desktop PC users back up their data on a regular basis, cloud computing is a data-safe computing platform. UNIVERSAL DOCUMENT ACCESS That is not a problem with cloud computing, because you do not take your documents with you. Instead, they stay in the cloud, and you can access them whenever you have a computer and an Internet connection. Documents are instantly available from anywhere.
