Applications are increasingly delivered for cloud deployment as set of composite artefacts such as containers. The composition descriptions vary widely: There are Docker compose files, Vamp blueprints, Kubernetes descriptors, OpenShift service instance templates, and more. Ideally, taking these compositions and deploying them somewhere would always work. In practice, it is more complex than that. Commercial production environments are often constrained depending on the chosen pricing plan. Many applications would still run but due to over-estimating deployment information do not “fit” into the target environment. In this blog post, we look at how to “right-size” an application deployed into such a constrained Kubernetes instance, and furthermore propose a tool to automate this process.
Last week on 16th June, we held our 5th Open Cloud Day. It took place this year at our campus (ZHAW Winterthur). We co-located another event of ours with the Open Cloud Day, the SDN Workshop.
Open Cloud Day is a joint activity, organised annually by ch/open/ and our research group, Service Engineering. The SDN workshop, a biannual event, focussing on the Software Defined Networking topic in cloud computing, is a joint activity between SWITCH and us.
The one day event hosted about 130 people, ran in 3 separate tracks; main, SDN and workshops, and covered a vast area of cloud topics. PaaS undeniably was the most discussed topic where some speakers took a provocative stance and others towards a positive and “game-changer” aptitude. Continue reading
We are extremely happy to announce that the 5th Open Cloud Day is going to take place at ZHAW, Winterthur, on the 16th of June this year.
We co-organise the Open Cloud Day with the Swiss Open Systems User Group. The main goal of the event is to foster open clouds and the interoperability of the clouds. We have seen tremendous interest and enthusiasm about this event from Swiss industries. We again welcome our friends from the industry and academia to join us at this event. Continue reading
The 4th Open Cloud Day, which we co-organised with The Swiss Open Users Group (/ch/open), took place earlier this week. The event held a gathering of about 120 participants, from industry and academia together. There were in total 17 talks and 3 workshop sessions.
ICCLab attended the OpenCloudDay in Bern en masse. Being one of the most known (infamous?) cloud computing groups in Switzerland, we had to show our strength at one of Switzerland’s most prestigious cloud events!
