Super-interesting interview with Zsolt Varga, the lead engineer and manager at Prerender.io. He shares how Prerender saved $800k by removing their reliance on AWS and building in-house infrastructure to handle traffic and cached data.
The goal was to reduce costs while maintaining the same speed of rendering and quality of service. Migrations like this need to be carefully planned and executed, as incorrect configuration or poor execution, would cause downtime for customer web pages and social media clicks and make their search rankings suffer and potentially increase our churn rate.
