Web portal for watching TV online.

LikeTV allows you to watch video broadcasts, TV channels, and video content from LikeTV partners, such as Megogo.

Initial conditions

— 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;

— 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 less than 10 seconds, then the connection is broken and again continues for another 10 seconds. Such a gap takes away minimal resources, occurs unnoticed by the server, and saves memory;

— Wrote scripts for testing video content, in order to automatically monitor video problems.
