This year we had the pleasure to organize and host one of Switzerland’s most prestigious cloud events, the OpenCloudDay. On the 30th of May, we welcomed the around 80 participants at the ZHAW School of Engineering in Winterthur for a day rich with technical talks, demos and networking possibilities for Cloud Computing practitioners and experts in Switzerland.
The program of the day started with two opening talks covering very timely topics in the field of Cloud Computing. The first talk, given by Thomas Michael Bohnert from the ICCLab, was a critical view on what many consider as the next evolutionary direction of Cloud Computing, namely Edge Computing. We got the speaker’s perspective on the motivations, the potential obstacles and open issues for this paradigm to definitely break through (or maybe not) as the next Cloud Computing frontier. The second opening talk was given by Sacha Dubois from Red Hat and focused on the potential of Ansible Tower for the automation and management of Hybrid Clouds. After a general discussion on the possibilities offered by Ansible Tower to managing both on-premise and public cloud workloads, a live demo showed how this would work in the practice.
During the second part of the morning and the first part of the afternoon, two technical sessions were ran in parallel. Several topics were covered as for instance Continuous Delivery, Continuous Deployment and Continuous Integration in the Cloud, and the CNCF activities during the last year, the challenges with the adoption of Web Application Firewall for the DevOps methodology and much more. An insightful presentation was given on the current cloudware technologies and what to expect from future post-clouds systems. Practical experiences were also presented as, for instance, in setting up a Kubernetes cluster, on the use of Ansible for cloud solutions. Also a workshop about the setup of an oVirt infrastructure for an open source Cloud Management Software was organized in the morning. For a complete program of the technical talks please visit the webpage of the OpenCloudDay.
The two final technical talks of the day were given by Niklaus Hofer from Stepping Stone and Jens-Christian Fischer from SWITCH. In the first of the two talks, a presentation was given on the analysis of storage performance for a Ceph cluster. More specifically, the focus was on the comparison between the new backend solution for the Luminous Ceph release, i.e. BlueStore, and the FileStore solution for storing data to disk. Open challenges and further open points of investigation were also given.
The last talk brought up a different point of view regarding all the technical solutions to run a cloud. Based on the experience of SWITCH in running an OpenStack/Ceph based cloud for the Swiss Academic community, the importance of the users’ role in using the technology was put in focus. The user’s perspective is not to be overseen as this puts additional challenges and requirements for solutions to be deployed as the experience of SWITCH clearly highlighted.
The program of the day also offered a total of seven demo presentations on the following topics: Cloud Robotics, Edge Computing, CAB, CNA, Service Tooling, ElasTest, T-Systems solutions.
Indeed a great post. Thanks for sharing with us. I would love to share this post. keep posting.
