Top 5 Open-Source Virtualization Software for Linux

This article covers the top-performing virtualization software specifically for Linux. Virtualization is the act of creating a "virtual machine" (VM) for every layer and system excerpted from the original, whether it is storage, hardware, computer network resources, or the operating system as a whole.

Virtualization is the process of developing virtual versions of operating systems, hardware platforms, storage devices, or computer network resources.

Basically, Some of the discussed virtualization paradigms are cross-platform such as XenProject, VirtualBox, and Microsoft Hyper-V, but Linux KVM and oVirt are specifically designed and created for the Linux operating systems.


A key advantage of running a virtual machine is that it allows you to run apps that would otherwise not be available due to having very different system requirements, which is one particular reason why virtualization has become so important in business.


The Top 5 Open Source Virtualization Software includes:

  • Xen Project.
  • VirtualBox.
  • KVM.
  • oVirt.
  • ProxMox.

Top 5 Open-Source Load Balancers 2021

This article reviews the Best Open Source Load Balancers. Load Balancing software assists virtual appliances in monitoring and distributing excess traffic. It helps network administrators and data centers maintain constant loading speed. The load balancing software is used to convey network traffic to specific servers with accurate configurations. 


Load Balancing Algorithms Types:

  • Round-robin Algorithm – The simplest method involves moving the requests within the same order to available servers. 
  • Least-time Algorithm – It selects servers supported by the smallest amount of active requests and the fastest processing speed. The algorithm integrates with powerful algorithms to give the server higher memory, capacity, and power. 
  • Least-connections Algorithm – This algorithm sends requests to servers with the smallest amount of workload. The algorithm sends requests to the smallest amount of busy servers. 
  • Hash-based Algorithm – It assists a hash key to the client and server IP addresses. The algorithm ensures that user's requests are sent to the identical servers containing data from the previous sessions. This ends up in an efficient network resource delivery.
