• How we reduced our annual server costs by 80%

  Zsolt Varga, the tech lead and general manager at Prerender.io, discusses how Prerender saved $800k by migrating away from AWS and building their own infrastructure. Prerender is a tool that caches and prerenders JavaScript pages, providing pure HTML files for search engines to crawl. By moving their cached pages and traffic to their own servers, they were able to cut costs by 80% in just over three months. The migration was carefully planned and executed to ensure minimal downtime and service degradation. The success of the migration allowed Prerender to reduce monthly server fees by 80%.
