I had done many courses(windows, Vmware and AWS)in vepsun and it is really a wonderful experience.
AWS training given by Sameer was really good. The lab books and extra labs which he made us to do topics specific helped us a lot to clear the AWS interview and it is helping me in day to day work. Even I have heard a lot about Sanjeev, waiting for my Azure and VMware vCloud class to begin.
The most important thing was their passion for technology and teaching. You ask question and they have best way to make you understand, I loved the time spent.
Thanks
