Private Cloud or Load Balancing

 
Hello,

I am looking to start a website for a university. This website will include all the information about that university. It will also contain videos of latest happenings in college. We will also start a online education program as well. So it will contain all the study material in video format. So the website will get a huge amount of traffic and I am looking for the best solution for it. I have heard about 2 things Private Cloud and Load Balancing. What are these two things and which one is better between these 2?I also checked Private Cloud Video and Load Balancing video for more information to know which is better but, did not find much .It would be great if you guys can help me out.

Any help will be appreciated.
Thank you.
