Azure Cloud Shell
- Azure Cloud Shell is a browser-based command-line experience for managing and developing Azure resources.
- Think of Cloud Shell as an interactive console that you run in the cloud.
Azure Regions
- A region is a geographical area on the planet containing at least one,
- but potentially multiple datacenters that are nearby and networked together with a low-latency network
- *There are also some global Azure services that do not require you to select a particular region,
- such as Microsoft Azure Active Directory, Microsoft Azure Traffic Manager, and Azure DNS.
- Example: West US, Canada Central, West Europe, Australia East, and Japan West
Special Azure regions:
- US DoD Central, US Gov Virginia, US Gov Iowa and more: These are physical and logical
- network-isolated instances of Azure for US government agencies and partners.
- These datacenters are operated by screened US persons and include additional compliance certifications.
- China East, China North and more: These regions are available through a unique partnership between Microsoft
- and 21Vianet, whereby Microsoft does not directly maintain the datacenters.
Azure Geographies
Geographies are broken up into the following areas:
- Americas
- Europe
- Asia Pacific
- Middle East and Africa
Each region belongs to a single geography and has specific service availability, compliance, and data residency/sovereignty rules applied to it
Availability Zones
- Availability Zones are physically separate datacenters within an Azure region.
- Each Availability Zone is made up of one or more datacenters equipped with independent power, cooling, and networking.
- It is set up to be an isolation boundary. If one zone goes down, the other continues working.
- Availability Zones are connected through high-speed, private fiber-optic networks.
- Not every region has support for Availability Zones.
The following regions have a minimum of three separate zones to ensure resiliency:
- Central US
- East US 2
- West US 2
- West Europe
- France Central
- North Europe
- Southeast Asia
