1. What is Microsoft Azure and why is it important for companies?
Ans:
Microsoft Azure is a cloud platform that provides services for computing, storage, networking, databases, analytics, and AI. It helps organizations scale infrastructure dynamically, cut down on physical hardware costs, and speed up software deployment. With global data centers, strong security measures, and flexible deployment options, Azure enables companies to create scalable, reliable, and modern cloud solutions efficiently.
2. How can organizations optimize workloads in Azure for better performance?
Ans:
To improve performance and efficiency, businesses can use features like auto-scaling to adjust resources based on demand, monitor usage with Azure Monitor, and follow recommendations from Azure Advisor. Right-sizing virtual machines, using appropriate storage tiers, and implementing security best practices ensure workloads remain cost-effective, high-performing, and resilient. These strategies help maintain a balance between performance and operational expenses.
3. What is an Azure Virtual Machine and when should it be used?
Ans:
An Azure Virtual Machine (VM) is a cloud-based server that provides on-demand computing resources. VMs are ideal when full control over the operating system is required, or when custom software or legacy applications need to be run. They are commonly used for migrating on-premises systems, hosting development and test environments, or running specialized applications that need dedicated resources.
4. How do Azure Resource Groups work, and why are they essential?
Ans:
Azure Resource Groups are containers that organize related cloud resources, such as virtual machines, storage accounts, databases, and network components. They make deployment, monitoring, and management easier by handling multiple resources as a single unit. Resource Groups also provide better access control, cost management, and lifecycle tracking, making them crucial for structured cloud operations.
5. What is the difference between Azure Storage and Azure SQL Database?
Ans:
Azure Storage is designed to store unstructured, semi-structured, and object data, including blobs, files, and disks, in a scalable way. Azure SQL Database, however, is a fully managed relational database for structured and transactional data. While Azure Storage handles flexible data storage needs, Azure SQL Database ensures consistency, query performance, and high availability for relational workloads, complementing a full data management strategy.
6. What purpose does Azure Active Directory (Azure AD) serve?
Ans:
Azure Active Directory is a cloud-based identity and access management system that handles authentication, access control, and user management for cloud and on-premises applications. It provides role-based access control, single sign-on, and multi-factor authentication to safeguard sensitive resources. Azure AD centralizes identity management, ensuring secure access and collaboration across the organization.
7. How is monitoring implemented in Azure?
Ans:
Monitoring in Azure is accomplished using tools like Azure Monitor, Log Analytics, and Application Insights to track resource health, performance, and availability. These tools help detect anomalies, provide actionable insights, and optimize resource utilization. Continuous monitoring ensures workloads are reliable, operational issues are addressed promptly, and overall cloud efficiency is maintained.
8. What is the difference between a Virtual Network (VNet) and a Subnet in Azure?
Ans:
A Virtual Network (VNet) is a private, isolated network in Azure that allows cloud resources to communicate securely. A Subnet is a segment of a VNet that organizes resources and helps manage IP allocation and network segmentation. VNets provide the overall network structure, while Subnets create logical divisions for better resource governance, security, and management.
9. How are Azure Alerts used?
Ans:
Azure Alerts notify administrators about performance issues, unusual resource usage, or potential security risks. Alerts can be sent via email, SMS, or integrated monitoring tools for immediate attention. They enable proactive management of workloads, helping maintain resource efficiency, security, and operational stability across Azure environments.
10. What is the purpose of an Audit Log in Azure?
Ans:
An Audit Log records all actions, changes, and user activities within Azure resources. It is essential for compliance, security monitoring, and governance. Reviewing Audit Logs allows organizations to track unauthorized activity, maintain accountability, and ensure cloud operations comply with organizational policies and regulatory standards.
