Replit founder shares AWS scaling lessons learned

The founder of Replit details his journey learning DevOps and AWS by building and scaling the company's code execution service. Initially, he relied on simple EC2 instances, but as the service grew, he encountered issues with single points of failure and the limitations of vertical scaling. This led to the adoption of horizontal scaling using AMIs and Elastic Load Balancers to manage multiple instances, eventually moving to Application Load Balancers for better WebSocket support. AI
