Building a fast and universal driver with clustered LVM and the QCOW2 for using any SAN-like storage system in K8s.
Over the past few years, we at Flant have been keeping a close eye on the technology leaders in the cloud-native space. But it’s more than merely a matter of curiosity — we have incorporated the ideas we got from them to create something new and exciting that would offer people a lot of value, which we would be pleased to share with you today. We present to you the new virtualization system we’ve recently introduced in the latest Deckhouse release (1.43).
With the introduction of the snapshot-controller in Kubernetes, it is now possible to create snapshots for CSI drivers and cloud providers that support this feature.
The API is universal and vendor-independent, which is typical for Kubernetes, so we can explore it without getting into the specifics of a particular implementation. Let’s take a closer look at snapshots and see how they can benefit Kubernetes users.
Nowadays the market offers a huge number of virtualization solutions. In this presentation we’ll take a look at application design approaches and explore the difference between virtualization and cloud computing. And take a look at IaC, Kubernetes and Terraform.

What has changed in the open-source communities after 2 years of lockdown? What are the threats and opportunities for open-source communities right now? We’ll discuss this and much more with the local open-source contributors and leaders.
There seems to be a new trend: every time I get a new job, the first activity I engage in is benchmarking different SDS solutions. My career at Flant is no exception. I joined the development team for the Deckhouse Kubernetes platform when it decided to focus on running virtual machines in Kubernetes. But first, we had to find an easy-to-use, reliable block-type storage that we could offer to the platform’s customers.
Hence I decided to benchmark several Open Source solutions to see how they behave under various conditions. The focal point was the DRBD performance in different configurations and how they compared to Ceph.
However, the market for software-defined storage is constantly growing and evolving. Ambitious new projects are emerging, including the recently released Mayastor and my fellow collaborator’s pet project Vitastor. The results were pretty exciting and surprising.
