Introduction :

Introduction Cloud computing is a model for enabling convenient on demand network access to share a pool of configurable computing resources That can be rapidly provisioned and released with minimal management effort or service provider interaction The essential features are service models and deployment models

History :

History The concept was born in the 1960s from the ideas of pioneers like J.C.R Licklider The John mcCaurthy form a global net work computation and framing computation as a public utility Flash forward to 1997,when the term “Cloud Computing” was used by first information systems professor Ramnath chellappa Within a just a few years, companies began switching from hardware to cloud services

Deployment models :

Deployment models The cloud deployment models define the pur pose of the cloud and nature of how the cloud is located there are four basic models Private model Public model Community model Hybrid model

Public cloud:

Public cloud Public cloud or external cloud describes cloud computing in the traditional mainstream sense, whereby resources are dynamically provisioned on a fine-grained, self-service basis over the Internet, via web applications/web services, from an off-site third-party provider who shares resources and bills on a fine-grained utility computing basis. A public cloud sells services to anyone on the Internet. (Currently, Amazon Web services is the largest public cloud provider.)

Private cloud:

Private cloud Private cloud or internal cloud are neologisms that some vendors have recently used to describe offerings that emulate cloud computing on private networks. These (typically virtualization automation) products claim to "deliver some benefits of cloud computing without the pitfalls", capitalizing on data security, corporate governance, and reliability concerns. They have been criticized on the basis that users "still have to buy, build, and manage them" and as such 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".

Hybrid cloud:

Hybrid cloud A hybrid cloud environment consisting of multiple internal and/or external providers "will be typical for most enterprises". By integrating multiple cloud services users may be able to ease the transition to public cloud services while avoiding issues such as PCI compliance. Another perspective on deploying a web application in the cloud is using Hybrid Web Hosting, where the hosting infrastructure is a mix between Cloud Hosting for the web server, and Managed dedicated server for the database server. Hybrid cloud basically combines both public and private cloud models together.

Community model:

Community model The cloud infrastructure shared by several organization and supports a specific community that shared concerns eg : mission , security requirements , policy , and compliance consideration

Advantages :

Advantages Fast application deployment Hassel free maintenance Better resource utilization Platform independent, security, scalability Backup and recovery Easy access to information Almost unlimited storage

Disadvantages:

Disadvantages Must have stable internet Slower than local software Concern about reliable and security Phone to attack Inflexibility
