Excellent course material. Can we have course from you for Elasticsearch xpack installation along with TLS enabled. But I must recommend everyone to go through this course its quite explanatory and to the point. Regards., Sagar

English of the speaker is very bad, the transcript won't help much. I think major topics are covered, but don't await that it goes too much deep. To me this course was created by mixing several separate slideshows. In almost each show the presenter will show you how to start Elastic search on MacOS, which is pretty waste of time when you hear it for the seventh time.
