Mirantis Training is the perfect place to get into the reality of OpenStack. The most beneficial parts for me were the general overview of OpenStack and the deep-dive into Nova networking. The hands-on workshop was also very helpful for learning to deploy OpenStack. I would highly recommend it to anyone looking for a clear, unbiased overview of OpenStack.
Aravinthan Gopalasingham Research Engineer, Alcatel-Lucent
Having gone through rigorous certifications, I find the MCA-100 exam to be of the highest quality. The test reflects accurately the content covered during the 3-day bootcamp. Most importantly in my opinion, is that the technological independence that Mirantis professes is accurately reflected in the exam. Highly recommended.
Ramiro Salas Global Technology Specialist, OpenStack
Just spent the last three days training with [Mirantis instructor] Polina Petriuk. Her class was--by far--the best training class I've taken in a long, long, time.
Joshua Feldman Director, Data Center
I would highly recommend Mirantis OpenStack training. The technical depth was excellent. Processes of authorization with tokens, databases, RabbitMQ and others were explained very well. Troubleshooting was explained very thoroughly and well structured. Every participant had a dedicated OpenStack cluster for practical work. The real life implementation with HA and other considerations was discussed.
Alexander Low Deutsche Borse Cloud Exchange AG, Germany
The most useful part of participating in OpenStack BootCamp was its combination of theory and practice, networking module and dedicated attention by instructor. With Mirantis extensive experience and guidance I learned about OpenStack functionality and use of Devstack for development which was exactly what I needed.
Miguel Lavalle OpenStack Developer
Great program that guides you through OpenStack architecture and highlights its capabilities and limitations.
Russ McElroy Manager – Storage Engineering
Technical overview, quantum networking and flow work for virtual machine creation made this class helpful for beginners as well as more advanced users.
Ahmed Al-Mehdi Sr. Software Engineer
The boot camp proved to be a great hands-on conceptual overview supported by knowledgeable instructors and presented at a comfortable pace.
Berry Weber CTO
This was a great experience even for someone just starting to learn OpenStack. The instructors were able to break down a complex concept into understandable steps and engaging examples.
Joseph Williamson OpenStack Cloud Network Engineer – Sr Adviser
The class did a great job at explaining Quantum and Folsom changes, deployment and use cases. Lectures were perfectly mapped to labs
Jeffrey Rametta Solutions Engineer
If you need a 2-day intensive introduction into the operation of OpenStack, this course is for you. In this program you will learn the limitations and capabilities of the various pieces that make up the system with focus on using both GUI and CLL. The variety of hands-on exercises as well as pointing out strengths and weaknesses of the system proved extremely useful.
David Kensiski Director of Technical Infrastructure
I attended Mirantis’ OpenStack training program seeking a better understanding of the OpenStack software architecture and operations practices. The program far surpassed my expectations and I consider it an excellent introduction to OpenStack. It's a quick jumpstart to the entire product.
Bernard Golden VP, enStratus
For me, the most useful part of attending this Boot Camp was seeing and interacting with the software. Putting hands on the system, talking to someone who had used it in production, and getting a better deep-dive than the manual/documentation at the process level were key benefits. I'd encourage people to take the class to get up to speed quickly.
Pat Holben CTO
The most useful part of this Boot Camp was getting a good understanding of the architecture, and meeting participants from other companies working on OpenStack. It helped me understand the status of the OpenStack Project in terms of how it can help our mutual customers today, and in the future.
