Question: What is Azure and what are its key components?
|
Answer: Azure is a cloud computing platform provided by Microsoft. Its key components include:
• Compute services (e.g., Virtual Machines, App Service)
• Storage services (e.g., Blob Storage, File Storage)
• Networking services (e.g., Virtual Network, Load Balancer)
• Database services (e.g., Azure SQL Database, Cosmos DB)
• Identity and Access Management (e.g., Azure Active Directory)
• Developer tools (e.g., Azure DevOps, Visual Studio)
• Monitoring and Management (e.g., Azure Monitor, Azure Resource Manager)

Question: Can you explain the difference between Azure Virtual Machines (VMs) and Azure App Service?
|
Answer: The Azure Virtual Machines provide scalable computing resources that you manage and maintain,
whereas Azure App Service is a platform-as-a-service (PaaS) offering that allows developers to build, deploy,
and scale web apps and APIs without managing the underlying infrastructure.

Question: What is Azure Resource Manager (ARM), and how does it facilitate resource management in Azure?
|
Answer: The Azure Resource Manager is the deployment and management service for Azure.
It provides a consistent management layer that enables you to create, update, and delete resources in your Azure subscription.
ARM allows one to manage resources as a group and apply access control, policies, and tags to resources.

Question: How does Azure Blob Storage differ from Azure File Storage and Azure Table Storage?
|
Answer: Here are the differences:
• Azure Blob Storage: Provides object storage for unstructured data. Suitable for storing large amounts of text or binary data, such as documents, images, and videos.
• Azure File Storage: Offers fully managed file shares in the cloud, accessible via the Server Message Block (SMB) protocol. Suitable for lift-and-shift scenarios where existing applications need file storage.
• Azure Table Storage: NoSQL key-value store suitable for semi-structured data. Provides schema-less storage for applications requiring flexible data structures.

Question: What is Azure Active Directory (AAD), and how is it used in Azure?
|
Answer: The Azure Active Directory is Microsoft's cloud-based identity and access management service.
It provides authentication and authorization services for applications and resources in Azure.
AAD enables:
• Single sign-on (SSO)
• Multi-factor authentication (MFA)
• Role-based access control (RBAC)
• Integration with other cloud services

Question: Can you explain the concept of Azure Virtual Network (VNet) and its importance in cloud computing?
|
Answer: The Azure Virtual Network enables one to create private networks in the Azure cloud.
It allows one to isolate resources, control inbound and outbound traffic with network security groups (NSGs),
and connect Azure resources to on-premises networks using VPN or ExpressRoute.
VNets are fundamental for building secure and scalable cloud infrastructures.
