This document discusses using Docker, Consul, and Ansible to manage distributed PHP applications. It covers microservices and SOA architectures, using Docker to containerize infrastructure components like databases and services, service discovery with Consul, and clustering applications with tools like Kubernetes and Nomad. It also addresses Dockerizing Symfony applications and some common pitfalls. The presentation aims to explain how to build and deploy scalable PHP applications using containerization and orchestration technologies.
