Performance Comparison between Light Weight Virtualization Using Docker and Heavy Weight Virtualization

These days everything is shifting to cloud computing. Two of the major types of clouds are infrastructure as a service (IAAS) & Platform as a service (PAAS) cloud. Network engineers and administrators make use of IAAS instead of physical hardware for implementing servers. Software Developers use PAAS for programming purposes. Virtualization is the main base for implementing cloud computing. The main types of virtualizations are Type 1 (also called hypervisor), Type-2 (called virtualization) and light weight virtualization (called operating System level virtualization). The problem with virtualization and hypervisor is that large time required for booting of the virtual machine (VM), very high VM installation time, large storage space consumed. The CPU and RAM usage is high. On the other hand, light weight virtualization is very fast, consumes almost negligible resources, container creation and start up time is extremely fast. Here we are comparing the performance of Virtual Box with Docker. Docker is based on lightweight container technology whereas virtual box represents heavy weight virtualization. First section will deal with introduction to docker and Virtual Box, second section contains comparison, third section experimental setup, fourth deals with performance analysis & last contains conclusion.
