John Studarus and Cynthia Thomas demonstrate how to service-chain traffic through multiple security functions using virtualization and software-defined networking (SDN). John and Cynthia walk you through configuring and modifying layer 2 service chains with open source cloud security tools to monitor and block malicious traffic originating from a network of virtual machines.

A developer hunting for a bug is like a doctor hunting for an illness. She does not need complete understanding of the body for the hunt to be successful. Jasvir Nagra and Marianna Bezler share a few painful distributed web app debugging anecdotes and an alternate approach using virtualization and visualization to get a holistic view of a program to track down elusive bugs.

OpenStack has gained a lot of prominence in the cloud ecosystem, but it can be a difficult platform to setup and maintain. Ganeti is a lesser known FOSS virtualization platform created by Google that …

Nils Magnus outlines the 12 stages of self-awareness that lead to ultimate container enlightenment. It's a long and winding road: while usual suspects like system engineers, developers, and system designers understand container virtualization fairly well, its architectural pattern remains a different cup of tea, and orchestration frameworks and auxiliary tools make it hard to see to the bottom.

Whether you are migrating existing applications or starting afresh with microservices, Clarence Bakirtzidis helps you get started on your journey to Docker-based production environments, focusing on an infrastructure-as-code approach via scripting and automation from the command-line interface.
