BRIDGE Design - Azure Availability Zones
Axess Digital Bridge infrastructure is by design built with 3 Azure Availability zones in Azure Region West Europe.
Definition of Azure Regions:
An Azure region is a set of datacenters deployed within an interval-defined perimeter and connected through a dedicated regional low-latency network.
Azure availability zones, as defined by Microsoft:
Azure availability zones are physically separate locations within each Azure region that are tolerant to local failures. Failures can range from software and hardware failures to events such as earthquakes, floods, and fires.
Tolerance to failures is achieved because of redundancy and logical isolation of Azure services. To ensure resiliency, a minimum of three separate availability zones are present in all availability zone-enabled regions.
Each zone is composed of one or more datacenters equipped with independent power, cooling, and networking infrastructure. Availability zones are designed so that if one zone is affected, regional services, capacity, and high availability are supported by the remaining two zones
