Percona Live Online 2021
Edmodo is an educational website that takes the ideas of a social network and refines them and makes it appropriate for a classroom. Our traditional peak period happens during the Back to School when students – and teachers – realize they have to go back to the classrooms and suddenly rush to the site to prepare their online alias to the school year.
Last year was different and it happened quickly and without too much warning in March when people were suddenly sent home from the schools to do all their tasks completely remotely.
That’s how our adventure started and this is when the site started doubling its traffic on a daily basis depending how many countries went into lockdown on that given day. The traffic on the dbs went up from 200K QPS to 5 million within a course of 3 week, we hit several limitations when scaling our dbs, sometimes we had no other choice but to make risky decisions but the site stayed up and running
