Microsoft Azure is a cloud computing platform and service offered by Microsoft. It provides a wide range of cloud services, including computing power, storage, and analytics, to help organizations build, deploy, and manage applications and services through Microsoft-managed data centers. 2. What are the key components of Azure? The key components of Azure include Azure Virtual Machines, Azure App Services, Azure Storage, Azure Virtual Networks, Azure SQL Database, Azure Active Directory, and Azure Functions. 3. What is the difference between Azure App Service and Azure Cloud Services? Azure App Service is a fully managed platform for building, deploying, and scaling web applications, mobile app backends, and RESTful APIs, while Azure Cloud Services is a platform that allows you to build, deploy, and manage applications using Microsoft-managed data centers. 4. What is Azure Virtual Network?
- 2. Azure Virtual Network allows you to create isolated virtual networks in Azure and securely connect them to your on-premises networks or other Azure virtual networks. It provides network connectivity, subnets, and customizable network configurations. 5. What is Azure Blob Storage? Azure Blob Storage is a scalable object storage service that allows you to store and retrieve large amounts of unstructured data, such as text or binary data. It is ideal for storing documents, images, backups, and other types of files. 6. What is Azure SQL Database? Azure SQL Database is a managed relational database service that provides a fully managed, highly available, and scalable database platform for running SQL Server workloads in the cloud. It offers built-in high availability, automatic backups, and intelligent performance optimization. 7. What is Azure Active Directory (Azure AD)? Azure Active Directory is a cloud-based identity and access management service that provides authentication and authorization for Azure resources, as well as integration with other cloud-based and on-premises applications. 8. What are the different deployment models in Azure? The different deployment models in Azure are Azure Resource Manager (ARM) and Azure Classic. Azure Resource Manager is the recommended deployment model, providing a more flexible and granular way to manage and deploy Azure resources. 9. What is Azure Functions? Azure Functions is a serverless computing service that allows you to run your code in response to events or triggers without the need to provision or manage any infrastructure. It enables you to build event-driven, scalable, and cost-effective applications. 10. What is Azure DevOps? Azure DevOps is a set of development tools and services that help teams plan, develop, test, and deliver software efficiently. It provides capabilities for version control, continuous integration and delivery (CI/CD), agile planning, and more. 11. What is Azure Load Balancer?
- 3. Azure Load Balancer is a Layer 4 load balancing service that distributes incoming traffic among multiple virtual machines or instances in Azure. It helps improve the availability and scalability of applications. 12. What is Azure Active Directory B2C? Azure Active Directory B2C (Business to Customer) is a cloud identity service that allows you to integrate identity management and authentication into your consumer-facing applications. It enables you to secure customer data and provide seamless sign-up and sign-in experiences. 13. What is Azure Site Recovery? Azure Site Recovery is a disaster recovery service that allows you to replicate and recover workloads from on-premises data centers or other cloud platforms to Azure. It provides automated replication, failover, and recovery options to ensure business continuity. 14. What is Azure Site Recovery? Azure Site Recovery is a disaster recovery service that allows you to replicate and recover workloads from on-premises data centers or other cloud platforms to Azure. It provides automated replication, failover, and recovery options to ensure business continuity. 15. What is Azure Functions Premium plan? Azure Functions Premium plan is a consumption-based plan that provides enhanced performance, scale, and advanced features for running serverless applications in Azure. 16. What are Fault Domains? Fault Domains in Azure refer to logical groups of hardware and network resources within an Azure data center. They are designed to provide resiliency by ensuring that services and applications are spread across multiple fault domains to minimize the impact of hardware or network failures. 17. What are Update Domains? Update Domains in Azure refer to logical groups of virtual machines (VMs) within an Azure Availability Set. They are used to ensure that during planned maintenance or updates, only a subset of VMs within an Availability Set are taken offline at a time, while the others remain available, ensuring high availability of applications.
- 4. 18. What are Network Security Groups? Network Security Groups (NSGs) in Azure are virtual firewalls that control inbound and outbound traffic to Azure resources. They provide network-level security by allowing or denying traffic based on rules and can be applied to subnets, network interfaces, or individual virtual machines to control network traffic flow. 19. Do scale sets work with Azure availability sets? Yes, Azure Scale Sets can work with Azure Availability Sets. By deploying VM instances in a Scale Set within an Availability Set, you can achieve both scalability and high availability for your applications, ensuring that instances are distributed across multiple fault domains and update domains. 20. What is a break-fix issue? A break-fix issue refers to a problem or malfunction in a system or software that needs to be resolved or fixed. It typically occurs when a component or functionality breaks and requires troubleshooting, diagnosis, and resolution to restore the system’s proper functioning.
