How to Save $1 Million on AWS WebSocket Bills A Case Study

In this blog post, we will discuss how Recall, a company that records meetings and provides transcripts, video files, and analytics, was able to save $1 million on AWS WebSocket bills by optimizing their infrastructure.

The Problem

Recall was spending $1 million per year on AWS due to inefficient Inter-Process Communication (IPC). This was caused by the high CPU usage of their bots, which were using 4 CPU cores to process video data.

The Solution

Recall optimized their IPC by using a ring buffer and zero-copy reads. This reduced CPU usage by 50%, saving them over $1 million per year.

The Key to Success

The key to Recall’s success was identifying and addressing the root cause of their high AWS costs. They focused on optimizing their IPC, which was the most expensive part of their infrastructure.
