What are Azure Virtual Machines (VMs)?
• Azure Virtual Machines are scalable computing 
resources offered by Microsoft Azure. They provide 
the flexibility of virtualisation without the need to 
buy and maintain the physical hardware that runs 
it. Azure VMs can be used in various scenarios, such 
as development and testing, running applications, 
extending your data centre, and much more.

• Key Features of Azure Virtual Machines
• Scalability and Flexibility:
o Vertical Scaling: Adjust the size of your VM to add more CPU, memory, 
or storage.
o Horizontal Scaling: Add more VMs to distribute the load.
o Auto-scaling: Automatically increase or decrease the number of VMs 
based on demand.
www.visualpath.in
• Wide Range of VM Sizes:
o General Purpose: Balanced CPU-to-memory ratio, suitable for most workloads.
o Compute Optimized: High CPU-to-memory ratio, ideal for medium traffic web 
servers, network appliances, and batch processes.
o Memory Optimized: High memory-to-CPU ratio, great for relational database 
servers, medium to large caches.
o Storage Optimized: High disk throughput and IO, best for big data, SQL, and 
NoSQL databases.
o GPU: Specialized VMs for heavy graphics rendering and video editing, model 
training and inferencing with deep learning.
o High-Performance Compute (HPC): Designed for intensive computing tasks like 
molecular modelling, fluid dynamics, and data analysis.

• Operating Systems:
o Windows: Various editions including Windows Server, and Windows 
10.
o Linux: Popular distributions like Ubuntu, CentOS, Debian, Red Hat, and 
SUSE.
• Managed Disks:
o Standard HDD: Cost-effective storage.
o Standard SSD: Better performance and reliability.
o Premium SSD: High-performance, low-latency disk storage.
o Ultra Disk: Optimized for I/O-intensive workloads.

Networking:
o Virtual Network: Isolate and secure your VMs.
o Load Balancer: Distribute traffic to multiple VMs for high availability.
o Application Gateway: Provides load balancing, SSL termination, and Web 
Application Firewall (WAF).
o VPN Gateway: Securely connect your on-premises networks to Azure.
Security and Compliance:
o Azure Security Centre: Unified security management and advanced threat 
protection.
o Azure Defender: Extended threat protection across your environments.
o Compliance Certifications: Meets a broad set of international and industry-
specific compliance standards. www.visualpath.in
Integration with Azure Services:
o Azure Backup: Simplifies data protection with automated backups.
o Azure Site Recovery: Ensures business continuity with disaster recovery.
o Azure Monitor: Full-stack monitoring, advanced analytics, and intelligent 
insights.
• Use Cases for Azure Virtual Machines
1. Development and Testing:
o Create isolated environments to develop and test applications without 
impacting production environments.
o Quickly provision and decommission VMs to test different configurations.
www.visualpath.in
1. Applications Hosting:
o Host web applications, mobile apps, and API services.
o Scale applications to meet changing demands without any hardware 
constraints.
2. Data Analysis and Big Data:
o Run big data solutions like Apache Hadoop, and Spark on VMs.
o Use high-performance VMs for computationally intensive data analysis.
3. Disaster Recovery:
o Replicate on-premises virtual machines to Azure for disaster recovery.
o Ensure data and application availability during outages or disasters.

Advantages of Using Azure Virtual Machines
1. Cost Efficiency:
o Pay-as-you-go pricing model reduces capital expenditure.
o Discounts with reserved instances and Azure Hybrid Benefit.
2. Global Reach:
o Deploy VMs in data centres across the globe for better performance and redundancy.
3. High Availability:
o Availability sets and zones provide high availability and redundancy.
o SLA guarantees for uptime and connectivity.
www.visualpath.in
1. Customization:
o Choose the exact specifications for your VM to match your workload 
requirements.
o Custom images for quick deployment of standardised environments.
2. Management Tools:
o Azure Portal, CLI, and PowerShell for easy management.
o Integration with DevOps tools for automated deployment and management.
• Best Practices for Using Azure Virtual Machines
1. Right-Sizing VMs:
o Choose the appropriate VM size based on workload requirements to optimize 
costs and performance. www.visualpath.in
1. Implement Security Best Practices:
o Use Azure Security Centre to monitor and enhance security posture.
o Regularly update VMs with the latest security patches.
2. Optimize Storage Costs:
o Use Managed Disks and select the appropriate type based on performance 
needs.
o Take advantage of Azure Blob Storage for cost-effective storage solutions.
3. Monitoring and Diagnostics:
o Set up Azure Monitor to track performance metrics and diagnose issues.
o Use log analytics for detailed insights into VM performance and health.

1. Backup and Recovery:
o Regularly back up your VMs using Azure Backup.
o Implement disaster recovery plans with Azure Site Recovery.
Azure Virtual Machines provide a versatile and powerful infrastructure as a 
service (IaaS) platform that can accommodate a wide range of workloads 
and applications. Their integration with other Azure services and features 
makes them a robust solution for businesses leveraging cloud computing.
