At the KubeCon and CloudNativeCon event in Paris earlier this month, Red Hat and Goldman Sachs discussed the benefits of using Kubernetes to manage virtual machines (VMs).
Red Hat engineering manager Fabian Deutsch started the presentation by discussing the flexibility of Kubernetes. He said that while Kubernetes is used to manage containers, it can also run VMs. “Everything you know about Kubernetes becomes immediately relevant for virtual machines as well. There is nothing new to learn,” he told the audience.
Red Hat’s OpenShift uses KubeVirt to containerise virtual machines. According to Red Hat, this means VM management inherits many features and functions from Kubernetes, including scheduling, high availability, and the ability to attach or detach IT resources.

Deutsch was joined on stage by Michael Hanulec, vice-president and technology fellow at Goldman Sachs. Hanulec sees many benefits in using Kubernetes to manage virtual machines.
“I’ve worked on server-based virtualisation for almost 17 years now, and over that time, we’ve seen a lot of products come and go, and a lot of technologies come and go. But we think Kubernetes is here to stay, and as such, it’s a good platform to build a future on,” he said.
Discussing the benefits, Hanulec said Kubernetes not only offers a strong, secure application programming interface (API), but also provides a way for IT administrators to work in the same way whether they are managing containers or VMs. Given that cloud-native computing is intricately linked to containerisation, Hanulec pointed out the ubiquity of virtual machines in enterprise IT.
“Hopefully you all realise that virtual machines are still very useful and are a trusted form of computing within today’s IT environment,” he said, addressing the audience. “You’ll find it broadly at a lot of enterprises, no matter how much people are talking about going to containers.”
Hanulec pointed out that when organisations discuss going to the public cloud, this involves running virtual machines on public infrastructure as service (IaaS).

One of the key benefits of using Kubernetes for virtual machine management, according to Hanulec, is the cloud-native community efforts that support what he and Goldman Sachs need to achieve. Among the community projects he said the bank uses are ArgoCD, which is used to automate the deployment of application configurations, and Kubernetes Operators, which helps to extend the platform.
Hanulec said it has also used the CNCF’s Container Storage Interfaces (CNCF-CSI) platform, which provides an interface between enterprise storage hardware and virtualisation. He said that while there are numerous virtualisation platforms, many only work with certain storage and network configurations.
“The beauty of Kubernetes is that you can choose how you want to put things together and optimise it for yourself,” Hanulec added.
