Azure Virtual Machines (VMs) provide on-demand, scalable computing resources in the Microsoft Azure cloud, allowing users to deploy and manage virtual servers with various operating systems. Key features include:
– Flexibility: Choose from Windows, Linux, or custom images, and scale resources up or down based on needs.
– Scalability: Easily add or remove VMs to handle varying workloads, with options for auto-scaling in response to demand.
– High Availability: Use availability sets, zones, or sets to ensure uptime and redundancy, minimizing downtime during maintenance or failures.
– Security: Integrated tools like Azure Disk Encryption, Network Security Groups, and Azure Active Directory for robust protection.
– Integration: Seamlessly connect with other Azure services, such as Azure Storage, Virtual Networks, and Load Balancers, for comprehensive cloud solutions.
– Cost Management: Pay-as-you-go pricing with options for reserved instances, spot VMs, or hybrid use benefits to optimize expenses.
Common use cases include hosting web applications, running development and test environments, processing big data, or migrating on-premises workloads to the cloud. To begin, create an Azure account, navigate to the Azure portal, and use the VM wizard to select size, OS, and configuration based on your requirements.
