The careerswales.com platform manages the education and professional progression of millions of people in Wales. When challenged with upgrading its ageing application stack to suit modern standards, we devised a solution with Symfony2 at its core. In this talk I'll discuss how the new stack was implemented, focussing on how we took advantage of Symfony2's first-class support for reverse-proxy Varnish to phase the deployment of the new system and improve performance by a significant amount. I'll also talk about the API we created to bridge its SQL Server / MySQL database platforms, and how Symfony2 was used to provide a single-sign-on solution across all of its web applications.
