There are many online DevOps training programs offered by many institutes like Edureka, Udemy, Intellipath, etc
-
Edureka DevOps Course (Experienced professional, provides demos, live training, good quality course material, also provides 24*7 support for any queries)
-
Udemy DevOps course (Udemy provides only recorded videos, not realtime online training by the instructor.)
-
Intellipath DevOps Training (the customer reviews of Intellipath is not good, so its ur personal choice to go with it or not)
Personally, I found Edureka's DevOps Online training course to be the best as I got to learn about popular DevOps tools like Git, Jenkins, Docker, Ansible, Puppet, Kubernetes, and Nagios.
Edureka's DevOps training is a hands-on wherein you will be exposed to real-time scenarios in the software development process which are not covered by other course providers.
Edureka provides a good list of DevOps Tutorial videos. I would recommend you to go through this tutorial video playlist as well as blog series.
