Describe Azure physical infrastructure Flashcards
What is the physical infrastructure of Azure?
Azure’s physical infrastructure consists of datacenters, which are facilities with resources arranged in racks, dedicated power, cooling, and networking infrastructure.
How are datacenters organized in Azure?
Datacenters in Azure are grouped into regions or availability zones to achieve resiliency and reliability for business-critical workloads.
What are Azure Regions?
Azure Regions are geographical areas containing at least one datacenter networked together with low-latency connections. They ensure workload balance and reliability by intelligently assigning and controlling resources.
What are Availability Zones in Azure?
Availability Zones are physically separate datacenters within an Azure region, each equipped with independent power, cooling, and networking. They provide isolation boundaries, ensuring continuity of services even if one zone goes down.
What is the purpose of Region Pairs in Azure?
Region Pairs consist of two Azure regions within the same geography, at least 300 miles apart. They enable replication of resources across geographies, reducing the risk of interruptions due to disasters or outages.
What are the advantages of Region Pairs?
Region Pairs prioritize restoration in case of extensive outages, minimize downtime during planned updates, and ensure data residency within the same geography for compliance purposes.
What are Sovereign Regions in Azure?
Sovereign Regions in Azure are isolated instances tailored for specific government or compliance needs. Examples include US DoD Central and China East, each serving unique requirements for government agencies or partners.
