HA 101 with OpenStack

Average rating: ****.
(4.00, 1 rating)

There are a number of interrelated concepts which make the understanding and implementation of HA complex. The potential for not implementing HA correctly would be disastrous.

Attend this session for a discussion on the interrelated concepts as a basis for implementing HA. The primary requirements for OpenStack based clouds (public, private or hybrid) is that they must be massively scalable and highly available. The session will have several demos and walk through some examples of HA for MySQL, Rabbit MQ and the OpenStack APIs primarily using Open Source components such as Keepalived, VRRP and HAProxy which will reinforce the concepts and show how to connect the dots. Although, we will use OpenStack as an example, the concepts will be applicable on a more general basis.

After attending this session, attendees will be able to walk away with an understanding of the pieces that constitute HA and how to fit these pieces together, possibly for their own application. They will also be able to evaluate different HA offerings to be able to pick and choose for their own needs.
