What is Microsoft Azure?
- Answer: Microsoft Azure is a cloud computing platform provided by Microsoft that offers a wide range of services, including computing power, storage, networking, databases, analytics, and more. It enables businesses to build, deploy, and manage applications and services through Microsoft's global network of data centers.
Explain the key components of Azure.
- Answer: Azure consists of several key components, including Azure Virtual Machines (VMs) for computing, Azure Blob Storage for scalable object storage, Azure SQL Database for managed relational databases, Azure App Service for web and mobile app hosting, Azure Virtual Network for networking, and Azure Active Directory for identity and access management.
What is Azure Resource Manager (ARM)?
- Answer: Azure Resource Manager is the deployment and management service for Azure. It enables you to deploy and manage resources in your Azure environment in a consistent and organized manner. ARM uses JSON templates to define and deploy resources as a group, known as an Azure Resource Group.
Explain the difference between Azure Blob Storage and Azure Table Storage.
- Answer: Azure Blob Storage is used for storing large amounts of unstructured data, such as documents, images, videos, and logs. Azure Table Storage, on the other hand, is a NoSQL data store used for storing semi-structured data. It's suitable for scenarios where you need to store and query non-relational data, such as key-value pairs.
What is Azure Active Directory (AAD)?
- Answer: Azure Active Directory is Microsoft's cloud-based identity and access management service. It allows users to sign in and access various applications and services with a single set of credentials. AAD provides features such as multi-factor authentication, conditional access policies, and integration with thousands of pre-built applications.
Explain the concept of Azure Virtual Network.
- Answer: Azure Virtual Network enables you to create private, isolated networks in the Azure cloud. It allows you to connect Azure resources, such as virtual machines and databases, to each other and to on-premises networks securely. Virtual Network provides features like subnetting, network security groups, and the ability to connect to other networks using VPN or Azure ExpressRoute.
What is Azure App Service and how is it used?
- Answer: Azure App Service is a fully managed platform for building, deploying, and scaling web apps. It supports multiple programming languages, frameworks, and operating systems. With Azure App Service, you can quickly build, deploy, and scale applications without managing the underlying infrastructure. It includes Web Apps, Mobile Apps, API Apps, and Functions.
Explain Azure Functions.
- Answer: Azure Functions is a serverless compute service that allows you to run event-triggered code without having to explicitly provision or manage infrastructure. You can write functions in multiple languages, and they can be triggered by various events, such as HTTP requests, changes in data, or messages in a queue. Functions scale automatically based on demand.
What is Azure DevOps?
- Answer: Azure DevOps is a set of development tools and services that facilitates the entire DevOps lifecycle. It includes features for version control, build automation, release management, and application insights. Azure DevOps helps development and operations teams collaborate and deliver software more efficiently.
Explain Azure SQL Database.
- Answer: Azure SQL Database is a fully managed relational database service in the Azure cloud. It provides features like automatic backups, scaling based on demand, and high availability. Developers can use Azure SQL Database to build and deploy applications that require a relational database without the need to manage the underlying infrastructure.
