What they had:

• The number of users did not exceed 3000. As the load increased, the response time of the server increased from 3 seconds to a minute;
• The video was completely cached in memory, and one user's video could take up 1.5 GB of RAM;
• The IT infrastructure consisted of Amazon servers.

What we did

• Carried out load-testing;
• Created a load on the Amazon server to 100,000 users. To prevent the channel from becoming clogged when testing video content, we added more servers;
• To prevent the memory from being consumed by 2-3 users, we reorganized the broadcast system. Now we get the video for not more than 10 seconds, then the connection is broken, and again continues for another 10 seconds. Such a gap takes away minimal resource, occurs unnoticed by the server and saves memory;
• Wrote scripts for testing video content, in order to automatically monitor video problems.
