Orchestration platforms automate the provisioning of cloud services and often include a self-service dashboard that allows the consumer to manage and deploy cloud services with a web browser. The automation used by cloud providers allows for fast deployment of new services
and applications.
Regions: Large cloud operations will actually partition operations into regions for fault tolerance and to offer localized performance advantages. A region is not a monolithic data center but rather a geographical area of presence.
Availability Zones: The actual data centers in each region are referred to as availability zones (AZs). Each region will usually have two or more availability zones for fault tolerance. The AZs are isolated locations within the cloud data center regions that the public cloud services providers originate and operate. Each availability zone is a physically separate data center
with its own redundant power and telecommunication connections. If they are in a geologically sensitive area, such as along a fault line or in a coastal area that may be subject to hurricanes or typhoons, they will be located a greater distance apart to minimize a natural disaster affecting more than one availability zone.
