During the last 5 years, many popular media players moved from CMS to low-level FrameWorks such as Symfony, Zend, Laravel. Some of them even dropped PHP in favor of new languages like Node or Python. They all had the same motivation : “web performances”, understanding response time, scalability and stability.But is that the best solution? In this talk, Gilles Guirand explains exactly why now is the time to reconsider PHP CMS, from the devOps culture to the metrics-centric approach, from the authenticated cache to CDN, from back-end to front-end optimization.
