Azure Virtual Machines are a cloud computing service provided by Microsoft Azure that allows users to create and run Windows or Linux virtual servers in the cloud without the need for physical hardware. Azure Virtual Machines enable organizations to quickly deploy computing resources, select from different VM sizes based on CPU, memory, and storage requirements, and scale resources according to workload demands. They include features such as flexible networking, integration with Azure storage services, built-in security controls, and options for load balancing and auto scaling to ensure performance and reliability. Compared to traditional on-premise infrastructure, Azure VMs provide greater flexibility, scalability, and cost efficiency because users can provision resources on demand and pay only for what they use. Organizations commonly combine Azure Virtual Machines with other Azure services to host applications, run development and testing environments, and build scalable, reliable cloud architectures that support modern business workloads.
