The Journey of Cloud Computing with Open Source

Abstract

Cloud computing is changing from a buzz word to a common technology nowadays. Though there is clarification for cloud computing for three types/layers: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), generally people talk about IaaS and PaaS when they talking about cloud computing. There are already several giant players, like AWS, Azure and GoogleCloud, in the market and it's a 100+ billions USD market[1],but it's a competitive market and there are new players coming in. And on the other hand, people can see big demand for private cloud as well. In this talk, I'd like to share our journey about building a public cloud with OpenStack[2]. Our journey started since 2014 and the idea incubated even earlier. I will generally cover how we design and implement our cloud from bare metal, to VM, then container/Kubernetes, and the road map targeting to serverless, mainly focus on the current stage, about building a high quality managed Kubernetes service. Recently having gone through the experience of building, implementing and running a Kubernetes platform service in our public cloud, Catalyst Cloud has some interesting experiences and war stories to share about the journey.
