    How were we running OSS applications on Azure ?

    Virtual servers

    Managed by Puppet/Ansible

    Shortcomings

    Scaling up/down takes manual effort & time

    PHP/MySQL/Solr/ElasticSearch versions/plugins defined by configuration management for each server, not for each project/deployment and have to be communicated separately

    Adding new technology (e.g. npm/grunt) is complex

  • VSHN AG I Neugasse 10 I 8005 Zrich I T 044 545 53 00 www.vshn.ch

    Wishful thinking...

    Solves build-ship-run workflow, integrates in CI/CD, DevOps & self-service

    Handles the standard software plattform problems: scaling, hitless deployment, monitoring, backup, etc

    Open standards: 100% open source, backed by big community

    No lock-in, free to choose any provider, works on any infrastructure

    Extensible with API

  • VSHN AG I Neugasse 10 I 8005 Zrich I T 044 545 53 00 www.vshn.ch

    Docker

    Lightweight container runtime

    Package code, runtime, plugins, libraries

    Helps you to use 12-Factor-App pattern (explicit entrypoint, port, volume configurations, see https://12factor.net)

    Automatically built, quickly started, one-time use

    From container to production ?

  • VSHN AG I Neugasse 10 I 8005 Zrich I T 044 545 53 00 www.vshn.ch

    Kubernetes

    Container orchestrator:

    How many of a kind should be running ?

    On which IP/port/machine are they ?

    How do they find each other ?

    What happens when a container/machine running them disappears ?

    Scaling, load balancing, rolling deployments

    OpenShift

    How to get the application in the container ?

    Web-GUI, CLI client, REST-API

    OpenShift

  • VSHN AG I Neugasse 10 I 8005 Zrich I T 044 545 53 00 www.vshn.ch

    APPUiO

    Managed Docker, Kubernetes, OpenShift

    Flavours: Big shared plattform in the cloud, private plattform in the cloud or on-premises

    Hosted in Switzerland (ISO/FINMA-certified) or whereever you want (Azure)

    Community for Developers and Operations, Dev & Ops = DevOps

    Free monthly half-day training TechLabs

    Starting at CHF 40/mt in Switzerland

  • VSHN AG I Neugasse 10 I 8005 Zrich I T 044 545 53 00 www.vshn.ch

    Why?

    You have full control over the container contents no more old versions by the hosting provider

    You control the build, deploy process from the GUI/CLI/API

    Plattform takes care of seamless deployment, SSL, load balancing, scaling, system updates, monitoring, backups, hardware, storage, network, etc

    You don't need to handle Docker, Kubernetes, OpenShift internals if you don't want to
