Microsoft Azure Fundamentals (AZ-900)Describe Azure architecture and servicesMedium
A global retail company is planning to deploy a new e-commerce application that must be highly available and resilient to regional outages. They need to distribute their application across multiple geographic locations to minimize latency for customers worldwide and ensure business continuity. Which Azure architectural component allows them to achieve this global distribution and resilience?
- AAzure Virtual Network (VNet)
- BAzure Regions
- CAzure Resource Groups
- DAzure Availability Zones
Show answer & explanationAnswer & explanation
Correct answer: B. Azure Regions
Azure Regions are geographically dispersed datacenters that provide high availability and disaster recovery by allowing applications to be deployed across multiple locations, ensuring global distribution and resilience.
Why the other options are wrong
- A. Azure Virtual Network (VNet) provides network isolation within a region and can connect to other VNets, but it's not the primary component for global distribution of an application for resilience.
- C. Azure Resource Groups are logical containers for resources and do not provide geographic distribution or resilience.
- D. Azure Availability Zones provide resilience within a single Azure region, not across multiple geographic locations.
Azure Regions
A set of datacenters deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network. They enable global distribution and disaster recovery.
- Geographically dispersed datacenters.
- Provide high availability and disaster recovery.
- Minimize latency for global users.
- Fundamental for global distribution.
Memory trick: Regions are like different cities around the world where you can set up your business.
