Azure Virtual Machines offers you the freedom of virtualization for various computing solutions, supporting Linux, Windows Server, SQL Server, Oracle, IBM, SAP, and others. Plus, all current-generation Virtual Machines come with load balancing and auto-scaling features at no extra charge.
What Is A VM Linux?
Virtual machines allow multiple operating systems to run at the same time on one physical computer. This flexibility is crucial for handling different OS environments required for various projects. It removes the necessity for several hardware configurations, simplifying workflows and lessening the difficulty of managing different systems.
Virtual machines (VMs) are separate computing environments that include CPU, memory, network interface, and storage, built from hardware resources. Virtualization enables one computer to function as several computers at the same time, which lowers costs and improves efficiency.
Initially developed in the 1960s for time-sharing on mainframe computers, VMs became widely used in the 2000s to make better use of costly hardware.
How Linux VM Works?
- The physical machine that operates VMs is referred to as the “host machine,” “host computer,” or “host OS.“
- The VMs utilizing its resources are known as “guest machines,” “guest computers,” “guest OSs,” or simply “guests.”
- A hypervisor software separates essential computing resources and facilitates the creation and management of VMs.
- Computing resources such as CPU, memory, and storage are viewed as a pool that can be shifted between guests or new VMs.
- Each OS or application functions similarly to an OS or application on the host hardware, simulating a real-time OS experience.
- A VM can be represented by a single data file and operates across various computers.
- The CPU processes CPU instructions as requested by the VMs, while the hypervisor oversees the scheduling.
- When a user or program makes a request for extra resources, the hypervisor allocates the request to the physical system’s resources.
Advantages of Virtualization in IT Operations
There are multiple benefits of using the Linux VM software over dual boot or cloud instances:
- Cost Savings: Operating several VMs on one host optimizes hardware use, cutting down the need for extra physical machines.
- Resource Management: Allocating CPU, memory, and storage dynamically based on demand guarantees effective resource usage.
- Flexibility and Growth: VMs make it simple to scale up or down to adapt to changing requirements without needing new hardware.
- Improved Disaster Recovery: VMs can be quickly backed up and duplicated, allowing for fast recovery in the event of hardware issues or data loss.
- Enhanced Security: Keeping different applications and workloads in separate VMs lowers the chances of security breaches and improves control over security measures.
