What is Microsoft Azure ?
Microsoft Azure is a cloud computing platform by Microsoft. It's a combination of interoperable cloud computing services that include open-source and standards-based technologies. Most important of all, the Microsoft Azure platform also includes many proprietary solutions from Microsoft as well as other companies.
What does it offer ?
In essence, it helps you build, deploy and manage applications.
How does it work ?
Well, Azure uses a technology known as virtualization. It separates the close coupling between a computer’s CPU or server and its operating system by means of an abstraction layer called a hypervisor. The hypervisor emulates all the functions of a real computer or server and its CPU in a virtual machine. You can run multiple virtual machines at the same time and each virtual machine can run any compatible operating system such as Windows or Linux.
Azure takes this virtualization technology and rethinks it on a massive scale in Microsoft data centres around the world. Therefore, the cloud is a set of physical servers in one or several data centres that run virtualized hardware on behalf of clients.
Each server includes a hypervisor to run multiple virtual machines.
A network switch provides connectivity to the servers. A server in each rack runs a special software called Fabric Controller. In turn, Each Fabric Controller is connected to another special piece of software known as the orchestrator.
The orchestrator is responsible for managing everything that happens in Azure, including responding to user requests. It assigns services, monitors the maintenance of the server and the services that run on it, and returns the servers to normal when an error occurs. Each instance of the Fabric Controller connects to another set of servers running orchestration software in the cloud, commonly known as a front-end. The front-end hosts the web services, the RESTful API and the internal Azure databases used for all functions that the cloud carries out.
