Understanding Cloud Computing 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 Insert a map of your country.

What is cloud computing ? Understanding Cloud Computing What is cloud computing ? Use of a network of remote servers which are hosted on the internet in order to store, manage & process data rather than using a local server or personal computer. Insert a map of your country.

Understanding Cloud Computing 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 Insert a map of your country.

Understanding Cloud Computing Models of Cloud The most recent achievements are the following models: Cloud Software as a Service (SaaS) use providers application over a network Cloud Platform as a Service (PaaS) Deploy customer created application to cloud Cloud Infrastructure as Service (IaaS) Rent processing, storage network capacity, and other fundamental computing resources. Cloud Hardware as a Service (HaaS) Reduce cost, less failure and crashes Insert a map of your country.

Understanding Cloud Computing Deployment models The cloud deployment models define the purpose of the cloud and nature of how the cloud is located there are four basic models Private model Public model Community model Hybrid model Insert a map of your country.

Understanding Cloud Computing 1. 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",. Insert a map of your country.

Understanding Cloud Computing 2. 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.) Insert a map of your country.

Understanding Cloud Computing 3. Community model The cloud infrastructure shared by several organization and supports a specific community that shared concerns. example : mission , security requirements , policy , and compliance consideration Insert a map of your country.

Understanding Cloud Computing 4. 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. Hybrid cloud basically combines both public and private cloud models together. Insert a map of your country.

Virtualization Principles Understanding Cloud Computing Virtualization Principles Server virtualization separates software from hardware. The low-layer virtualization software abstracts a virtual hardware interface by means of space segmentation, timed division, and emulation to provide the upper-layer OSs with an expected hardware environment.

Understanding Cloud Computing A Cloud refers to a distinct IT environment that is designed for the purpose of remotely provisioning scalable and measured IT resources. Insert a map of your country. Figure 1.1 The symbol used to denote the boundary of a cloud environment.

Understanding Cloud Computing IT Resource An IT resource is a physical or virtual IT-related artifact that can be either software based, such as a virtual server or a custom software program, or hardware-based, such as a physical server or a network device ( figure 1.2 ) Insert a map of your country.

Understanding Cloud Computing Scaling Scaling from an IT resource perspective, represents the ability of the IT resource to handle increased or decreased usage demands. The following are types of scaling: Horizontal Scaling - scaling out and scaling in Vertical Scaling - scaling up and scaling down Insert a map of your country.

Understanding Cloud Computing Cloud Service A cloud service is any IT resource that is made remotely accessible via cloud. Unlike other IT fields that fall under the service technology umbrella - such as service - oriented architecture - the term "service" within the context of cloud computing is especially broad.
