What are Azure Regions and why are they important?
Azure Regions are geographical areas on the planet that contain one or more datacenters connected via low-latency networks. They are important because they allow users to deploy resources in specific locations, ensuring proximity to users and compliance with regulations.
What are Availability Zones, and how do they contribute to application resilience?
Availability Zones are physically separate datacenters within an Azure region, each equipped with independent power, cooling, and networking. They contribute to application resilience by providing isolation boundaries; if one zone fails, others continue to operate.
What is an Azure Region Pair, and what advantages does it offer?
An Azure Region Pair is when most Azure regions are paired with another region within the same geography, at least 300 miles away. It offers the advantages of enhanced resilience against regional outages, prioritized restoration during extensive outages, and staged updates to minimize downtime.
What is the purpose of Azure Sovereign Regions?
Azure Sovereign Regions are isolated instances of Azure, separate from the main Azure environment and are designed for compliance or legal requirements, such as US government agencies or those in China.
Explain the difference between an Azure Resource and a Resource Group.
An Azure Resource is a basic building block, like a virtual machine or a database, while a Resource Group is a container that holds these resources, providing a way to manage them together.
How do Azure Subscriptions relate to Resource Groups, and what two types of boundaries can they establish?
Azure Subscriptions are used to organize resource groups and facilitate billing, providing authenticated and authorized access to Azure products and services. They can establish billing boundaries for cost management and access control boundaries to reflect different organizational structures.
What are Azure Management Groups and what benefit do they provide for large organizations with multiple subscriptions?
Azure Management Groups provide a level of scope above subscriptions, enabling large organizations to efficiently manage access, policies, and compliance across multiple subscriptions. They allow for governance conditions to be applied that all child subscriptions automatically inherit.
What is the difference between the Learn Sandbox, a free Azure account, and a free Azure student account?
The Learn Sandbox is a temporary subscription for completing Learn exercises at no cost; a free Azure account includes limited access to certain Azure products for 12 months, and a credit to use for the first 30 days; a free Azure student account offers free access to certain Azure services for 12 months and a credit for the first 12 months, specifically for students.
