Online learning of technical courses is becoming popular but reaching to online classroom on exact time or not supporting smart devices to access course sessions is a limitation that is well addressed by Platzi.
Zillionize has invested in Platzi – An online education platform to teach advanced technical courses from industry leaders. It offers almost all courses but focuses mainly on programing, designing and marketing related courses. The classes are live streamed and recorded to give an experience of live classroom where students and teachers easily collaborate with each other. If some course session is missed, educate yourself from the recorded video of that session. Additionally you can access guides, tutorials and bonus live streaming classes to cover up the live education sessions that were missed.
