DevOps to the rescue?
– Repeatable, Reliable & Incrementally Improving
– Constant flow of changes to benefit users
– Infrastructure as Code > Infrastructure as Art
– Frequent Small Batches > Infrequent Big Batches
– Time Vampires
– Manual Builds
– Manual Testing
5
Unit Tests did we create working code?
Integration Tests do these work together?
End-to-End Tests does the Platform we built work?
Performance Test did we break/de-tune something?
Deployment Tests do we have everything?
Configuration Tests can we test different environments before hitting the real environment?

Ingredients of successful DevOps
Tools
– Source Code Management e.g. git
– Artifact Repository e.g. maven
– Review Management System e.g. Gerrit
– Integration Engine e.g. Jenkins
– Configuration Management System e.g. Ansible, Chef
– Test Harness – rally, tempest, yardstick, qtip
– Flexible System Deployment Engine, e.g. cobbler, vagrant
Principles & Practices
– Infrastructure as Code
– Declarative Topologies
– Test driven development
– Agile development
– Move towards micro-services architecture
8
Infrastructure as Code
– Configuration management on steroids
– Core tenet of DevOps
– Bring tried-and-tested practices from software engineering into infrastructure operations
– Revision control
– Uses standard git tool
– Track both what was changed and why
– Audit all changes to the cluster
– See precisely what has changed between two points in time
– Makes many compliance use-cases trivial to fulfill

Helion CI / CD Approach
– HPE helped establish OpenStack CI/CD pipeline
– Helion leverages this approach for OpenStack distributions
– Same approach leveraged by Non OpenStack products within Helion portfolio

Reduce Risk and focus on Business
Value & Innovation by leveraging NFVi
platform.
Enable competitive business strategy
to nimbly attack new revenue streams.
Reduce time to market and speed
certified VNF’s from POC’s and Trials to
commercialized services.
How NFV System is DevOps Ready?
– Built using DevOps principles (3 week sprints, geographically distributed teams, daily scrums, etc.)
– Infrastructure deployed as code using a system schema (json)
– System schema deployed using a configuration management tool (ansible) using a declarative toplogymodel
– Flexible deployment options for production and QA scenarios on bare metal and virtualized environments (cobbler, vagrant)
– Infrastructure as code components managed using a source code management tool (git)
– Code components fenced through a rigorous review mechanism (gerrit)
– Code changes unit and integration tested using an integration engine (Jenkins)
– Platform validation using open test harnesses (rally, tempest)
