Full stack troubleshooting and monitoring in OpenStack environments

Full stack troubleshooting and monitoring in OpenStack environments (45 mins)

Many companies leverage the advantages of having a private cloud running on OpenStack: fewer costs, more control, no vendor lock-in. However, they also need to take care of operations and maintenance. OpenStack monitoring and troubleshooting are nontrivial tasks and require time, knowledge, and experience. Hundreds of log files are written by numerous services with several configuration files to countless virtual and physical machines - the possibilities for errors seem endless. Moreover, the performance of applications running on OpenStack can be affected by other applications or even the cloud platform. In such heterogeneous environments, manual root cause analysis is like looking for the needle in the haystack. We’re going to look at common problems in OpenStack environments, how application performance can be affected, analyze root causes, and discuss options for effective and efficient operation and troubleshooting.

DevOps Guide to Container Networking (30 min)

Programmable network connectivity and network overlay technologies like Docker Networking, Flannel, and Calico are essential tools for DevOps engineers using orchestration tools to manage and deploy Docker containers in production. Because network troubleshooting and optimization falls within the jurisdiction of DevOps, it’s vital that DevOps engineers understand exactly how network overlays work. Participants will learn the fundamentals of container networking, see practical examples of common network overlays, and receive guidance on effectively using and tuning network overlays.
