The Kubernetes train stops in Europe this week, as over 4,000 attendees attend keynote sessions and technical talks that continue through Friday on containers, container-orchestration, microservices, and even serverless computing at Kubecon and CloudNativeCon in Copenhagen.

Cloud vendors and toolmakers announced several new products and services this week, almost all of which paid homage to the role Kubernetes has assumed within the cloud-native software development world. We already told you about Seattle’s Upbound, which launched at the event with $9 million in funding from GV to build multicloud management tools based on Kubernetes.

Here’s a limited sample of other developments from the week:

Google unveiled several new services and projects at the show, with a particular focus on security. The company announced the release of an open-source framework for securing containerized apps as well as the addition of several new security vendors to its Cloud Security Command Center. It open-sourced a container runtime called that gVisor that separates containerized apps from the operating system kernel, and also rolled out a new Kubernetes monitoring service.

Red Hat, fresh off its acquisition of CoreOS, announced a new open-source project built by CoreOS called Operator Framework, which specifies a way of managing Kubernetes clusters. An “operator” is basically a standardized way of managing some of the lower-level activities required to maintain a Kubernetes cluster, and also includes a meter for judging how much certain users are running on a given cluster.

Oracle showed up in Copenhagen with improvements to its Oracle Container Engine for Kubernetes focused on security and storage. It also showcased a few additions to its open-source Fn Project — an attempt to built open industry standards around serverless computing principles — with support for CloudEvents and a contribution to the Serverless Framework.

Digital Ocean, a niche cloud-computing vendor, is also getting in on the Kubernetes game with the launch of its own managed Kubernetes service. The company is known for its simple, inexpensive cloud computing services catering to developers, but Kubernetes support is becoming table stakes for any cloud provider.
