How Azure works
- It uses virtualization
- Uses an abstraction layer called hypervisor.
- Separates tight coupling between hardware (CPU, RAM, GPU..) and its operating system
- Emulates a real computer in a virtual machine
- Can run multiple virtual machines in same time
- Optimizes capacity of abstracted hardware
- Can run any OS such as Windows, Linux & macOS
- Azure repeats virtualization in massive scale
- Each data center has many racks filled with servers
- Each server includes a hypervisor to run multiple virtual machines.
- A network switch provides connectivity to all those servers
- One server in each rack runs a special software called fabric controller
- Each fabric controller is connected to another software called as orchestrator
- Orchastrator manages everything in Azure, including responding user requests
- Users requests using Azure API
- Azure API can be reached in many ways including Azure Portal
- Orchestrator packages everything it’s needed and sends to package & request to fabric controller.
