The latest News and Information on DevOps, CI/CD, Automation and related technologies.
This is the second part of the two-part blog series covering embedded Linux systems and the challenges brought about by the proliferation of Internet of Things (IoT) devices. In Part I, we surveyed the embedded ecosystem and the role Linux plays within that space. This blog takes you on the next step in the journey, where we explore the most demanding challenges facing manufacturers of tightly embedded IoT devices.
In one of our preceding blogs, we spoke about Software-Defined Networking (SDN) and the key drivers behind it. Virtualisation is one of the fundamental aspects that characterises SDN, and has influenced the architecture of network switching in the data centre. OVS (Open vSwitch) is a fundamental component of modern and open data centre SDNs, where it aggregates all the virtual machines at the server hypervisor layer.
