2 Agenda OPEN-O Introduction DevOps Practice: Toolchain Compass

3 Agenda OPEN-O Introduction DevOps Practice: Toolchain Compass

4 Service Agility Calls for Open Source Orchestration Weak development capability Developers How to orchestrate SDN /NFV and legacy networks? SDN / NFV Complex legacy OSS for new services Orchestrator Open - Orchestrator

5 OPEN-O: Any Service Over Any Network APP / BSS / OSS OPEN-O It s about the services * End-to-end * Model-driven Multi- SDN Controller Multi-VNFM /VIM Multi-EMS Redevelop brownfields * Connectivity services * SDN and EMS system Tailored to the operator * Guided by real use cases * Modular framework

6 OPEN-O Release Schedule and Update Officially launched at June 7, 2016 Released Sun Release at Nov 3, OPEN-O passed RC1 milestone last Thursday, targeting toward release Mercury at April 27, 2017 February 23, 2017 ~ 5 months ~ 6 months

7 Agenda OPEN-O Introduction DevOps Practice: Toolchain Compass

8 The Challenges for OPEN-O Integration 5-6 months release cycle Codebase 13 projects 56 Repos, 1,553,618 LOC (as of 4/1/2017) Developers 125+ Span 16 hours of time zones: Asia, Europe, US End-to-end multi-vendors real equipment, PNF and VNF, deployment in Integration community labs

9 OPEN-O DevOps Practice Software Architecture: deployability, modifiability, testability, etc. Continuous Integration is important;; testing is key Unit tests: OPEN-O Mercury requires 50% UT coverage System integration tests: cover all main functions A full DevOps toolchain

11 OPEN-O Toolchain OPEN-O Toolchain covers key aspects of DevOps: code, build, test, package, release, deployment, configuration, and monitoring

12 CI Toolchain: Gerrit Widely used in open source projects: OPEN-O, OpenStack, OpenDaylight, OPNFV, etc. Facilitates collaboration between developers.

13 CI Toolchain: Jenkins Continuous integration server widely used in open source projects Extensive support of plugins

14 OPEN-O CSIT Infrastructure OPEN-O Mercury has 79 CSIT test suites, 519 test cases Test Suites written using Robot Framework OPEN-O Microservices run via docker Mock southbound services run via docker using Moco Simulator e.g. mock VIMs or SDN controllers Robot test suites executed via Jenkins Docker Containers Jenkins Master Jenkins Slave VM OPEN- O Microservice 1 OPEN- O Microservice 3 Robot process OPEN- O Microservice 2 Mock Services / Components

15 OPEN-O Jenkins Job Flow Code Per Project Code Change Proposed Code Verify Job / Unit Test Pass? No Yes Code Change Merged Code Merge Job / Unit Test SonarQube (Static Analysis) Nexus (Java SNAPSHOT Artifacts) Docker Definition Per Microservice Docker Change Proposed Docker Verify Job Pass? No Yes Docker Change Merged Docker Merge Job Docker Hub (Docker SNAPSHOT Images) Test Suite Per Functionality Test Suite Change Proposed CSIT Verify Job Pass? Yes Test Suite Change Merged CSIT Test Job CSIT Test Job 2, etc. No

16 OPEN-O Jenkins Autorelease / RC Job Flow Code Cross- Project Daily Cron Trigger Autorelease Build Job (Builds All Projects Together From Source) Nexus (Java RC/Release Artifacts) Docker Definition Per Microservice Docker Merge Job Docker Hub (Docker RC/Release Images) Test Suite Per Functionality CSIT Test Job CSIT Test Job 2, etc.

19 Agenda OPEN-O Introduction DevOps Practice: Toolchain Compass

20 Compass Deployment Automation Platform Automate deployment of cloud infrastructure Support multiple OpenStack versions/flavors Support major SDN solutions Support VNFs in NFV architecture SaaS-based Compass Configuration and deployment from Cloud Simple local agent in your DC

21 Compass - Highlights Extensible architecture A unified data modeling with metadata support Build on open source tools Ansible, Chef Docker Cobbler TinyCore

22 Compass Support composable software architecture

23 Compass Active in open source communities: OpenStack OPNFV OPEN-O How to use compass Web UI REST APIs Python Client library

24 Compass Plugin Mechanism

25 Compass Ansible

26 Compass in action - CMCC Lab Compass was used in Beijing CMCC Lab for the deployment of OPEN-O Sun release Compass SDNController OPEN- O Infrastructure NOS NOS NOS Switch Router Switch Host OS Host OS Host OS 26

27 OPEN-O DevOps Practice Benefits Significantly shorter time to release Better project quality More reliable release Key success factors Modular architecture: micro-services Good tool chains, ideally all automated.
