I was considering taking a course but wasn't sure what to choose and was unsure whether I could accomplish it. Goms sir is the one who gave me confidence and helped me become an expert in both openshift and DevOps. I begin both concepts with no prior understanding of openshift and DevOps. Now I understand what to do with openshift and DevOps. He clarified all of my clarifications. I've never seen such a dedicated teacher in my life. Thank you once more, Gom Sir

The Best place to 1.Enhance your carrier 2.Change your Non-IT domain to IT domain 3.Get your dream job with good hike. I have done my devOps course and Redhat openshift certification recently in CubenSquare. Pros : 1.Very skilled trainers for each technology. Specially our trainer GOMS, the way he teach each topic with correlated realtime examples (live projects) in layman terms makes better understanding and register in our mind easily. 2. They provide very clear live running notes for each class with recordings, with all presentation, nowhere institute will provide this .So after years also we can easily refer incase of doubts. 3. I personally like, the classes are much more practical sessions rather just showing PPT and boring. 4. They follow perfect class timings, No last minute changes. At rare case if any changes we get to informed before itself. 5. Both weekdays/weekend and online/offline available. 6.Very reasonable price for each course, mainly they have easy instalment option which is helpful for most of students. 7. Good placement opportunities as being recruitment partners with TATA and other organisation. 8. All over best place to make your carrier better with all needed stuffs in technologies . Cons: Honestly No🙅

I really enjoyed this class and the format it was presented in. For me, I learn and retain much more through an online class. I retain more information. I found it relaxing to be able to turn the work on the assignments and test at my leisure and when I had the time. To be honest, there is nothing that I disliked about the course. Special thanks to Goms for guiding me. Thank you once again.
