Server virtualization software is a type of virtualization software that enables the creation and management of virtual servers on a physical server. It allows multiple virtual servers, each with its own operating system and applications, to run simultaneously on a single physical server. Server virtualization software typically includes a hypervisor or virtual machine monitor (VMM), which manages the virtual servers and provides them with access to the underlying physical resources.
The hypervisor creates virtual machines (VMs) that mimic the hardware of a physical server, including CPU, memory, storage, and network interfaces. Each virtual server operates independently and is isolated from other virtual servers, allowing for better resource utilization and improved flexibility.
Benefits of Server Virtualization Software
Consolidation: Multiple virtual servers can run on a single physical server, reducing hardware costs and improving resource utilization.
Isolation: Each virtual server operates independently, providing isolation from other virtual servers. This enhances security and stability.
Flexibility: Virtual servers can be easily provisioned, scaled, and migrated across physical servers, enabling dynamic resource allocation and workload balancing.
Disaster recovery: Virtual servers can be replicated or backed up, making it easier to recover from system failures or disasters. Virtualization technology refers to the set of software and hardware technologies that enable virtualization. These technologies work together to create and manage VMs and provide the necessary infrastructure for virtualization.
Key Components of Virtualization Technology
Hypervisor: Also known as a virtual machine monitor (VMM), the hypervisor is a software or firmware layer that enables the creation and management of virtual machines. It abstracts and partitions the underlying physical resources, such as CPU, memory, and storage, and allocates them to virtual machines.
Host machine: This refers to the physical server or computer that runs the hypervisor and hosts the virtual machines. It provides the necessary processing power, memory, and storage to support the virtualization environment.
Guest machine: A guest machine is a virtual machine running on the host machine. It operates independently and can run its own operating system and applications.
Virtual machine manager: This software component allows administrators to manage and control the virtual machines. It provides functionalities such as VM creation, configuration, monitoring, and resource allocation.
Virtualization APIs: Application Programming Interfaces (APIs) enable integration and interaction between virtualization software and other management tools or applications. They allow developers to automate tasks, monitor performance, and manage virtual environments programmatically. Virtualization technology offers numerous benefits, including improved resource utilization, increased flexibility, easier provisioning and migration of VMs, enhanced security through isolation, and simplified management of IT infrastructure.
Virtualization software examples include VMware vSphere, Microsoft Hyper-V, and Scale Computing HyperCore.
VMware Alternative
The vast majority of Scale Computing Platform users have come from a VMware environment and we are seeing increased demand as of late. We would recommend anyone considering this switch to read the reviews of former VMware customers to know that they aren’t alone in this journey.
