Virtualization allows the creation of a separate computing environments within the same host.

Distribute systems A distributed system is a collection of independent computers that appears to its users as a single coherent system.

Three major milestones have led to cloud computing: mainframe computing, cluster computing, and grid computing.

Virtualization Virtualization is essentially a technology that allows creation of different computing environments.

These environments are called virtual because they simulate the interface that is expected by a guest EX: Hardware virtualization, Storage and Network virtualization.

These capabilities are obtained by integrating a collection of standards and technologies such as XML, Asynchronous JavaScript and XML (AJAX), Web Services, and others Ex: Google Documents, Google Maps, Flickr, Facebook, Twitter, YouTube Blogger, and Wikipedia.

Service-oriented computing Service orientation is the core reference model for cloud computing systems.

This approach adopts the concept of services as the main building blocks of application and system development.

Service-oriented computing (SOC) supports the development of rapid, low-cost, flexible, interoperable, and evolvable applications and systems.

A service is an abstraction representing a self-describing and platform-agnostic component that can perform any functionanything from a simple function to a complex business process A service is supposed to be loosely coupled, reusable, programming language independent, and location transparent.

Utility-oriented computing Utility computing is a vision of computing that defines a service- provisioning model for compute services in which resources such as storage, compute power, applications, and infrastructure are packaged and offered on a pay-per-use basis With the advent of cloud computing, the idea of providing computing as a utility like natural gas, water, power, and telephone connection has become a reality today.

Application development Web applications, enterprise applications resource-intensive applications.

Data-intensive compute-intensive applications.

Infrastructure and system development Distributed computing, virtualization, service orientation, and Web 2.0 form the core technologies enabling the provisioning of cloud services from anywhere on the globe.

Microsoft Azure It provides a scalable runtime environment for Web applications and distributed applications Applications in Azure are organized around the concept of roles, which identify a distribution unit for applications and embody the applications logic.

Currently, there are three types of role: Web role, worker role, and virtual machine role.

The Web role is designed to host a Web application, the worker role used to perform workload processing, the virtual machine role provides a virtual environment in which the computing stack can be fully customized, including the operating systems.

Hadoop Apache Hadoop is an open-source framework that is suited for processing large data sets on commodity hardware Hadoop is an implementation of MapReduce, MapReduce is programming model which provides two fundamental operations for data processing map reduce.

Map transforms and synthesizes the input data provided by the user; Reduce aggregates the output obtained by the map operations.

It supports a collection of programming abstractions Developers can choose different abstractions to design their application.

Virtualization allows the creation of a secure, customizable, and isolated execution environment for running applications, These environments are called virtual because they simulate the interface that is expected by a guest.

EX: Hardware virtualization, Storage and Network virtualization virtualization is widely used to deliver customizable computing environments on demand major causes for the diffusion of hardware virtualization solutions are performance and computing capacity Underutilized hardware and software resources.

Lack of space Greening initiatives Rise of administrative costs.

The host is instead represented by the physical hardware, and in some cases the operating system, that defines the environment where the virtual machine manager is running.

All the operations of the guest are generally performed against the virtual machine, This level of indirection allows the virtual machine manager to control and filter the activity of the guest, thus preventing some harmful operations from being performed.

Sensitive information that is contained in the host can be naturally hidden without the need to install complex security policies.

This becomes the perfect environment for running applications without affecting other users in the environment.
