Core Azure architectural components (regions, availability zones, resource groups)

Lesson 2.2: Core Azure Architectural Components

🔹 Azure Regions

• Region: A set of datacenters deployed within a specific geographic location.
• Microsoft Azure is available in geographically distributed regions around the world.
• Each region is a separate deployment area, such as East US, West Europe, Southeast Asia, etc.
• Choosing a region close to your users reduces latency and improves performance.

🔹 Availability Zones

• Availability Zones: Physically separate datacenters within a region.
• Each zone has independent power, cooling, and networking.
• Used to enhance availability and fault tolerance for applications and data.
• You can replicate applications across zones to ensure high availability.

🔹 Resource Groups

• Resource Group: A container that holds related Azure resources.
• Resources that share the same lifecycle (e.g., web app, database, storage account) should be grouped together.
• You can manage resources collectively (monitoring, access control, deletion, etc.)
• Each resource must exist in one resource group, and a resource group can span across regions.

📌 Summary

• Regions define the geographical location.
• Availability Zones provide fault isolation within regions.
• Resource Groups help manage and organize resources effectively.
