Web applications requires robust PHP and MySQL architectures. This may be for high availability, for sheer performances, or even both. Yet, there is always the nagging question of doing so in an economically viable way. Architecture is not black magic : coming right from the mission goal, it will take most of the load and still look nice in the accounting tables.
During this session, we'll study a number of architectures solutions available to modern PHP architects, and discuss about their impact on availability, performances, PHP programmation, MySQL organization and econometrics.
