OpenStack Operations

This course is for IT professionals starting to run OpenStack clouds as well as those who are managing and supporting existing Open Stack clouds. System administrators starting to work with cloud technologies will benefit particularly.

This course assumes that you are familiar with Linux, SQL databases, and virtualization.

You must be comfortable administering and configuring multiple Linux machines for networking. One of the most complex aspects of an OpenStack cloud is the networking configuration so, you should be familiar with concepts such as DHCP, Linux bridges, VLANs, TCP/IP and iptables.

You must be able to install and maintain a MySQL database, and occasionally run SQL queries against it.

We recommend that students attend our OpenStack Fundamentals course prior to attending this more advanced, Operations course.
