4. Case Study – LinkedIn iPad App
“On the server side, our entire mobile software
stack is completely built in Node. We use a ton
of technologies at LinkedIn, but for the mobile
server piece, it’s entirely Node-based”
Kiran Prasad,
Director of Engineering,
Mobile at LinkedIn

5. Result - LinkedIn iPad App
“The improvements the team saw were
staggering. They went from running 15 servers
with 15 instances (virtual servers) on each
physical machine, to just four instances that can
handle double the traffic. The capacity estimate
is based on load testing the team has done”
