1. What is Azure and what services does it offer?
Answer: Azure is a cloud computing platform and infrastructure created by Microsoft for building, deploying, and managing applications and services through a global network of Microsoft-managed data centers. It offers a wide range of services including compute, storage, databases, analytics, AI, IoT, and more.
2. Can you explain the difference between IaaS, PaaS, and SaaS?
Answer: IaaS (Infrastructure as a Service) provides virtualized computing resources such as virtual machines, storage, and networking. PaaS (Platform as a Service) provides a platform for building and deploying applications and services without having to manage the underlying infrastructure. SaaS (Software as a Service) is a software delivery model in which applications and services are provided over the internet and managed by a third-party provider.
3. How does Azure Virtual Network (VNet) work?
Answer: Azure Virtual Network (VNet) is a logically isolated section of the Azure cloud that you can use to deploy your virtual machines and other resources. VNets provide a secure and scalable way to connect your resources to the internet and to each other. VNets allow you to control inbound and outbound network traffic using network security groups and IP security policies.
4. Can you explain Azure Active Directory (AD)?
Answer: Azure Active Directory (AD) is a cloud-based identity and access management (IAM) solution that provides secure authentication and authorization for applications and services. Azure AD integrates with on-premises Active Directory and allows administrators to manage user access and identity through a centralized portal.
5. What is Azure Resource Manager (ARM)?
Answer: Azure Resource Manager (ARM) is a deployment and management service for Azure resources. ARM provides a unified management layer for deploying, managing, and monitoring resources in Azure. It enables you to declare all the resources for your solution in a single JSON file and deploy the resources as a single, coordinated unit.
6. How does Azure Load Balancer work and what are its benefits?
Answer: Azure Load Balancer is a network load balancer that enables you to distribute incoming network traffic evenly across multiple virtual machines in a load-balanced set. It provides high availability and scalability for your applications, helps ensure low latency and high throughput, and provides automatic load distribution across multiple virtual machines.
7. What is Azure Autoscale and how does it work?
Answer: Azure Autoscale is a feature that enables you to automatically scale your Azure resources based on the demand for your application. It works by monitoring the performance of your virtual machines and adjusting the number of instances up or down as needed to meet demand. Autoscale helps ensure that your application remains available and responsive, even during periods of high traffic.
8. Can you explain Azure Blob Storage and its use cases?
Answer: Azure Blob Storage is a cloud-based object storage solution that enables you to store and retrieve large amounts of unstructured data, such as images, videos, audio, and documents. Blob storage is optimized for serving unstructured data and is ideal for use cases such as backup and disaster recovery, content distribution, and big data analytics.
9. What is Azure Service Bus and what are its use cases?
Answer: Azure Service Bus is a fully managed messaging service that enables you to send and receive messages between applications and services. Service Bus provides a secure and reliable way to communicate between applications, even when they are running on different platforms or in different data centers. It is ideal for use cases such as application integration, service-oriented architecture
