Describe Azure architecture and services: Describe the core architectural components of Azure Flashcards
What is Microsoft Azure?
Azure is a continually expanding set of cloud services that enable you to build, manage, and deploy applications globally using your preferred tools and frameworks.
What do you need to create and use Azure services?
An Azure subscription.
What does the Azure Free Account include?
Access to 20 Azure products free for 12 months.
Access to 25+ products that are always free.
A credit to use during the first 30 days.
What is the foundation of Azure’s physical infrastructure?
Azure datacenters, grouped into regions and availability zones.
What is an Azure region?
A geographical area containing one or more datacenters connected by low-latency networks.
What is an Azure availability zone?
A physically separate datacenter within a region, with independent power, cooling, and networking for increased resilience.
How many availability zones are present in an enabled region?
At least three.
What is a region pair in Azure?
Two geographically distant regions paired for resilience and redundancy, enabling data replication and disaster recovery.
What are sovereign regions in Azure?
Isolated Azure regions designed for compliance and legal requirements, such as US Gov regions and China regions.
What is an Azure resource?
Anything you create, provision, or deploy in Azure, such as virtual machines, databases, and networks.
What is an Azure resource group?
A logical grouping of resources, enabling collective management (e.g., applying actions or permissions to all resources in the group).
Can a resource group contain another resource group?
No, resource groups cannot be nested.
What happens when you delete a resource group?
All resources within that group are also deleted.
What is an Azure subscription?
A unit of management, billing, and scale, linking resources to a specific billing account.
What are the two boundaries defined by an Azure subscription?
Billing boundary: Determines how costs are tracked and billed.
Access control boundary: Determines access management policies.
What are common use cases for creating multiple subscriptions?
Separate billing for production and development environments.
Isolating resources for compliance or organizational needs.
Managing access for different departments or teams.
What is an Azure management group?
A level of hierarchy above subscriptions, used to organize and apply governance, access, and policy controls to multiple subscriptions.
How many management groups can be supported in a single Azure directory?
Up to 10,000.
What is the depth limit for a management group hierarchy?
Six levels, not including the root or subscription level.
What is inherited when using Azure management groups?
Policies and permissions applied to a management group are inherited by all its subscriptions and resource groups.
What is the Microsoft Learn Sandbox?
A temporary subscription provided by Microsoft Learn to create and test Azure resources during exercises.
What is the purpose of billing profiles in Azure?
To create separate invoices and payment methods within the same billing account.
Why use availability zones in your application architecture?
To run mission-critical applications with high availability and resilience by replicating resources across zones.
What are the three types of Azure services related to zones?
Zonal services (pinned to a specific zone).
Zone-redundant services (automatically replicated across zones).
Non-regional services (resilient to zone and region outages).
