From monolith to µService

Make software faster available Produce higher quality Make your services globally available Improve your services with customer feedback Reduce your cost Automate all

<=>

Build, Ship and Run Any App, Anywhere

deliver prepackage software

Docker works locally and in the cloud with the same binary with the same functionality with the same version with the same filesystem layout with the same dependencies but with different Linux kernels! This dream is now reality... => Infrastructur First

Use Linux at bare metal, instead a virtual machine provider

Docker Engine 1.10.x Docker Volumes- and Network-Manager Docker Toolbox 1.10.x Docker Machine 0.6 Docker Swarm 1.1 Docker Compose 1.6.x

Resource and Container Management Volume Management Network Management Process Configuration Image Handling Monitoring Metrics Logging

create docker machines provision with docker daemon and docker swarm plugable drivers

https://github.com/docker/swarm Scheduling docker containers at multiple machines Maintain docker machine cluster Support multiple discovery services Support filtering, affinity and constraints Open API and first batteries included Master/Slave Cluster Support

describe a reproduceable runtime config define service groups support swarm support docker network

Create your own build pipeline Create a lot of tests Package your software well Deploy and maintain distributable Monitoring your services This are the hard things, as before!

Kubernetes Docker Swarm Mesos GCE AWS ECS

add metrics design for failure setup of multiple machines... handling your persistence states on classic infrastructure your developer need a prod like environment
