This paper proposes the use of Linux OS for real-time applications with the aid of Sitara ARM processor, AM335x. The Sitara AM335x SoC is equipped with two 32-bit low-latency microcontrollers called Programmable Real-time Units (PRUs), forming Programmable Real-time Unit Subsystem (PRUSS). PRUs can be individually programmed to do a specific task independent of the arm processor. This provides many advantages like fast operation with near to real-time processing speed and offload of deterministic and timecritical tasks from the ARM core.
Cloud computing is a type of Internet-based computing that provides shared computer processing resources, services and data to computers on demand. It offers an innovative business model for organizations to adopt IT services at a reduced cost with increased reliability and scalability. Virtualisation is one of backbone technology of cloud computing. But today, container based technology especially Docker offering better performance than Virtual Machine. It is famous for its light weight operation and better scaling. But still it is lagging in Disk I/O and network bandwidth intensive applications. So it is important to analyse and compare various performance parameters of VMs and Docker Images before implementation. Main Parameters will be CPU, Memory, Disk Utilization and Network Bandwidth. In this research paper, we compare performance metrics between Webserver deployed in Virtual machine and Docker webserver.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
