This document discusses cloud computing. It defines cloud computing as network-based computing that takes place over the Internet using integrated hardware, software, and networking services delivered through the Internet. Cloud computing provides on-demand access to shared computing resources like servers, storage, databases, and more via the web or mobile devices. The document outlines different cloud deployment models including private, public, hybrid and community clouds as well as different service models like SaaS, PaaS and IaaS. It discusses advantages like cost efficiency and convenience as well as disadvantages like security concerns and limited features of cloud computing.

Cloud Computing describes a 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 simple graphical interface or API (Applications Programming Interface). 2

Different Types Of Cloud’s Characteristics Private Clouds • Cloud is controlled completely by the enterprise • All data in resource under control of legal and contractual umbrella of the organization • Require Capital Expenditure and Operational Expenditure and highly skilled labor Public clouds • External organizations provide the infrastructure and management of the cloud • Billed based on usage • Data in an offsite organization outside the legal and regulatory umbrella • Difficult to document the physical location of data at any particular moment 7 Hybrid Clouds •Combine public and private clouds •Coordination between the private and public service management system

- 9. Security and Challenge 9 Protecting datacenters must first secure cloud resources and uphold user privacy and data integrity. Trust overlay networks could be applied to build reputation systems for establishing the trust among interactive datacenters. A watermarking technique is suggested to protect shared data objects and massively distributed software modules. These techniques safeguard user authentication and tighten the data access- control in public clouds. The new approach could be more cost-effective than using the traditional encryption and firewalls to secure the clouds.

Editor's Notes
- Cloud Computing works in a way similar to how our water and electricity services work- we use the service, how much we use is monitored and we pay for only what we use.That means cloud computing is an outside and in some cases a 3rd party provider that provide services via the internet, giving the users immediate access. There are 3 different services that cover the foundation for cloud computing.SAAS- A SaaS provider typically hosts and manages a given application in their own data center and makes it available to multiple users over the WebPAAS-. This services is an application development and deployment platform delivered as a service to developers over the Web. IAAS- this service is the delivery of hardware (server, storage and network), and associated software (operating systems virtualization technology, file system), as a service. Unlike PaaS services, the IaaS provider does very little management other than keep the data center operational and users must deploy and manage the software services themselves--just the way they would in their own data center.
- In a private cloud, the infrastructure for implementing the cloud is controlled completely by the own company. Typically, private clouds are implemented in the own data center and managed by internal resources. This eliminates the management and security concerns associated with information being processed on third party computing resources. Currently, private clouds require Capital Expenditure and Operational Expenditure as well as highly skilled labor to ensure that business services can be met.
- As we focus on building the cloud, a number of models have been developed for deploying a cloud infrastructure.
- Cloud computing and grid computing are two new concepts of computing. They are often mistaken for the same thing, however that is not the case at all.
