Rightsizing Kubernetes applications

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.

Highlights – Open Cloud Day 2016

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.
