Azure Virtual Machines. They are a core component of the Microsoft Azure cloud platform, providing on-demand, scalable computing resources. Users can deploy a wide range of operating systems and software applications in a hosted environment. This service enables organizations to run enterprise software and develop cloud-native applications without maintaining physical hardware.

Overview

Azure Virtual Machines form a fundamental Infrastructure as a service offering within the broader Microsoft Azure ecosystem. The architecture allows for the creation of virtual machines in Microsoft's global network of data centers, providing high availability and redundancy. This model supports a diverse array of workloads, from legacy client-server applications to modern containerized applications using tools like Docker and Kubernetes. The underlying hypervisor technology is based on Microsoft Hyper-V, ensuring isolation and performance for each instance.

Features and capabilities

The service offers a comprehensive set of features, including support for both Windows Server and various Linux distributions from partners like Red Hat and Canonical Ltd.. Users can select from a vast gallery of pre-configured virtual machine images or create custom ones. Key capabilities include automated scaling through Azure Virtual Machine Scale Sets, integration with Azure Managed Disks for storage, and high-performance options featuring NVIDIA GPUs and Intel processors. Advanced networking is facilitated through the Azure Virtual Network, enabling secure connections to on-premises infrastructure via Azure ExpressRoute.

Deployment and management

Deployment is managed through multiple interfaces, including the Azure Portal, Azure PowerShell, the Azure Command-Line Interface, and infrastructure-as-code tools like Terraform and Azure Resource Manager templates. Ongoing management and monitoring are handled by services such as Azure Monitor and Microsoft System Center. For governance and automation, administrators utilize Azure Policy and Azure Automation. The Azure Site Recovery service provides robust disaster recovery capabilities, while Azure Backup ensures data protection.

Pricing and cost management

Pricing follows a pay-as-you-go model, with costs accruing based on the selected virtual machine size, operating system, and region. Microsoft offers significant discounts through Reserved Instances for one or three-year commitments and Azure Hybrid Benefit for customers with existing Windows Server licenses. Tools like Azure Cost Management and Billing, powered by Cloudyn, help organizations analyze spending and optimize resource utilization. The Azure Pricing Calculator allows for detailed cost estimation before deployment.

Security and compliance

Security is multi-layered, incorporating features like Azure Security Center for threat protection and Microsoft Defender for Cloud. Network security is enforced through Azure Firewall and Network Security Groups. All data is encrypted at rest using Azure Disk Encryption and in transit via protocols like TLS. The service complies with a broad set of global standards, including ISO 27001, SOC 1, SOC 2, HIPAA, and the General Data Protection Regulation. Identity and access are managed through integration with Azure Active Directory.

Use cases and common scenarios

Common use cases include migrating existing on-premises applications to the cloud, a process often facilitated by the Azure Migrate service. They are ideal for running SQL Server databases, SAP environments, and high-performance computing workloads for fields like genomics and financial modeling. Developers use them for building and testing applications within DevOps pipelines integrated with Azure DevOps Services. Other scenarios include hosting web servers, running desktop virtualization via Azure Virtual Desktop, and serving as backend compute for complex applications using Azure Kubernetes Service.
