Talk presented at the English Only Track on June 9th 2019 at Darkmira Tour PHP 2019 in Fortaleza, Ceara - Brazil. We covered some concepts, vantages and disadvantages comparing Micro-services and Monolith architectures. Then we showed Istio, what it is, how it works and its components. We made some demos showing microservices running on docker, then they running over a Kubernetes cluster and how the deployment and rollback works in high availability modes, and then we finished running the same stack with Istio and how to create routes, inject failures and make a canary deployment. The video of the demos and the code will be available soon.
