Introduction to Cloud Computing and OpenStack - overview course

Basic knowledge of Cloud Computing paradigm.

The course is dedicated to IT engineers and architects who are looking for a solution to host private or public IaaS (Infrastructure as a Service) cloud via OpenStack.
This is also great opportunity for IT managers to gain knowledge overview about possibilities which could be enabled by OpenStack.

Before you decide on OpenStack implementation by yourself, further investigation on the topic or hireing a 3rd party for the implementation, you could consider all pros and cons by attending on our course.
This topic is also avaliable as individual consultancy.

Course goal:

understand how Public Cloud differs from Private Cloud in the offering and management

gaining basic knowledge regarding OpenStack
