A Performance Analysis of Virtual Mail Server on Type-2 Hypervisors

Abstract

Virtualization is now the most efficient and successful procedure to use server resources. Virtualization is a technology that will efficiently allow the instructions or programs based on the available hardware. With the help of virtualization, we can achieve benefits like reduced capital and operating costs, minimized downtime, increased productivity, and good disaster recovery, etc. This work compares the virtual mail server performance on 3 different Hypervisor software. The 3 different type-2 hypervisor software we chose to compare were Kernel-based Virtual Machine (KVM), Oracle VirtualBox, and VMware. A computer system that sends and also receives an email over a network either on LAN or the internet is called a Mail Server. Although large ISPs and public email services have their dedicated hardware, in most cases, the web servers and mail servers are hosted on a single machine by virtualization. When a Mail server is implemented on the hypervisor, it is then considered as a virtual mail server. A virtual mail server is good at load balancing and has many more benefits. This paper presents how to implement a virtual mail server and shows the comparative results of the virtual mail server on different type-2 hypervisor software. HIGHLIGHTS Virtualization will efficiently run the instructions or programs based on the available hardware The virtual mail server has more significant advantages than the standard mail server. It helps in achieving faster deployment of mail servers with fewer hardware requirements Comparison of the performance of the virtual mail server on three different Type-2 Hypervisor software: Kernel-based Virtual Machine (KVM), Oracle VirtualBox, and VMware The web servers and mail servers can be hosted on a single machine by virtualization A virtual mail server is best for load balancing and disaster recovery as well
