Openstack CI infrastructure Overview
Openstack is one of the largest OSS projects today with hundreds of commits flowing in daily. This high rate of change requires an advanced CI infrastructure. The purpose of the talk is to provide an overview of this infrastructure, explaining the role of each tool and the pipelines along which changes have to travel before they find their way into the approved Openstack codebase. Talk delivered by Anton Weiss at Openstack Day Israel 2016 : http://www.openstack-israel.org/#!agenda/cjg9 [slideshare id=62796201&doc=openstackci-160607053245]
Infrastructure As Code Revisited
One can not talk about modern software delivery without mentioning Infrastructure As Code (IAC). It’s one of the cornerstones of DevOps. It turns ops into part-time coders and devs into part-time ops. IAC is undoubtedly a powerful concept – it has enabled the shift to giant-scale data centers, clouds and has made a lot of lives easier. Numerous tools (generally referred to as DevOps tools) have appeared in the last decade to allow codified infrastructures. And even tools that originally relied on a user-friendly GUI (and probably owe much of their success to the GUI) are now putting more emphasis on switching to codified flows (I am talking about Jenkins 2.0 of course, with it’s enhanced support of delivery pipeline-as-code). IAC is easy to explain and has its clear benefits: It allows automation of manual tasks (and thus cost reduction) Brings speed of execution Allows version control for infrastructure configuration…
