Azure Interview Questions

Microsoft Azure is a cloud computing platform and service created by Microsoft for building, deploying, and managing applications and services through a global network of Microsoft-managed data centers. It supports various service models like IaaS, PaaS, and SaaS.

The main categories are:

• Compute (e.g., Azure Virtual Machines, Azure Functions)
• Storage (Blob Storage, File Storage)
• Databases (Azure SQL Database, Cosmos DB)
• Networking (Virtual Network, Load Balancer)
• Analytics (Azure Synapse, HDInsight)
• AI & Machine Learning
• Security & Identity (Azure Active Directory)

Azure Virtual Machines (VMs) are scalable compute resources in Azure that allow you to run applications in the cloud just like on a physical server, but with flexibility to scale up/down and pay-as-you-go pricing.

Azure Blob Storage is a service for storing large amounts of unstructured data like images, videos, documents, or backups, accessible from anywhere over HTTP/HTTPS.

Azure uses Azure Active Directory (Azure AD) for identity and access management, supporting multi-factor authentication, single sign-on, and role-based access control (RBAC) to secure resources.

AKS is a managed Kubernetes service that simplifies deploying, managing, and scaling containerized applications using Kubernetes in Azure.

Azure Functions are serverless compute services that allow you to run event-driven code without managing infrastructure, billed only for actual execution time.

Data can be secured using encryption at rest and in transit, network security groups, Azure Key Vault for managing secrets and certificates, and Azure Security Center for threat detection.

Azure DevOps provides developer services for CI/CD (Continuous Integration and Continuous Deployment), including repositories, pipelines, test plans, and artifacts to support agile development.

Azure Monitor is used for collecting, analyzing, and acting on telemetry from Azure resources, providing alerts, dashboards, and log analytics.

An ARM template is a JSON file that defines the infrastructure and configuration for Azure resources declaratively. It allows you to deploy, update, or delete resources consistently and repeatedly using Infrastructure as Code (IaC).

Availability Zones are physically separate datacenters within an Azure region designed to protect applications and data from datacenter failures by providing high availability with redundancy.

Azure Logic Apps is a cloud service that helps automate workflows and integrate apps, data, and services using a visual designer without writing code.

Azure Cosmos DB is a globally distributed, multi-model NoSQL database service designed for low-latency, scalable, and highly available applications.

Azure supports hybrid cloud via services like Azure Arc (manage on-premises and multi-cloud resources), Azure Stack (run Azure services locally), and VPN/ExpressRoute for secure connectivity.

ExpressRoute is a dedicated private connection between your on-premises infrastructure and Azure data centers, offering higher reliability, faster speeds, and lower latencies compared to public internet.

Managed Disks simplify disk management by handling storage account management for you. They provide better scalability, availability, and security for VM disks.

Azure Policy helps enforce organizational standards and assess compliance by creating rules that govern resource properties during deployment or for existing resources.

Azure Blob Storage is optimized for general object storage, while Azure Data Lake Storage is designed for big data analytics workloads with hierarchical namespace and optimized performance for analytics.

Azure Sentinel is a cloud-native Security Information and Event Management (SIEM) tool that provides intelligent security analytics and threat detection across the enterprise.
