A Review on Container-Based Lightweight Virtualization for Fog Computing

Innovation in the concept of virtualization acts as a vigorous role in cloud computing. Virtualization helps in splitting the system resources in the form of the multiple and isolated execution environments. Hypervisor-based virtualization is related to the huge requirement of resources and operative overhead due to an additional stage of abstraction. In this review, we first were given an overview of virtualization innovation and Container-based virtualization. Container-based virtualization provides performance enhancements and reduced starting time and hence it is more beneficial than Virtual Machine (VM). Container virtualization does not imitate the hardware but only isolate the processes and it is more light-weight than VM. Container-based virtualization may be successfully implemented in "Fog Computing" framework as containers are suitable to the resource-constrained environment and also enables the distribution of different type of applications on cloud and fog Nodes. This paper describes the possible application of lightweight virtualization to Fog Nodes in the form of case studies.
