Members of the LINBIT® team will speak at upcoming conferences, focused around cloud, virtualization, containerization, and orchestration technologies. LINBIT CEO and DRBD® creator, Philipp Reisner, and LINSTOR® for CloudStack lead developer, Rene Peinthor, will each present at the 2025 CloudStack Collaboration Conference, 19-21 November, in Milan, Italy. LINSTOR for Kubernetes lead developer, Moritz Wanzenböck, will present at the Cloud Native Computing Foundation (CNCF) community group virtual conference, CozySummit Virtual 2025, 3 December.
In the wake of marketplace shake-ups, particularly in the proprietary virtualization software sector, many enterprises are seeking or have already moved to open source options for orchestrating containers and virtual machines (VMs), or for building their own clouds. Kubernetes and CloudStack are two robust and long-lived (in software years) open source platforms that have become the backbone for many enterprises. An open source solution gives users the peace of mind that the solution cannot be taken away from them. Users are free to “fork” the solution if they need to, customize the solution based on their needs, inspect the codebase to vet for quality or security vulnerabilities, and enjoy other freedoms that proprietary software users do not have.
The LINBIT commitment to open source
Open source has been a pillar of LINBIT software development for over 20 years, beginning with the LINBIT flagship software for facilitating data and application high availability (HA), DRBD®. More recently, LINBIT developers have built upon this foundation with other open source software such as LINSTOR for software-defined storage (SDS) and disaster recovery (DR), DRBD Reactor for HA cluster resource management, LINSTOR Gateway for creating highly available NFS, iSCSI, or NVMe-oF targets, and more.
The 2025 CloudStack Collaboration Conference
While the 2025 CloudStack Collaboration Conference, 19-21 November, does not have a nominal theme, it is not difficult to deduce from the presentation titles and abstracts that the topics of repatriation, migration, and digital sovereignty are important to the CloudStack community. At the conference, on Thursday, 20 November, LINBIT CEO, Philipp Reisner will discuss DRBD and LINSTOR feature developments, such as scalability, security, and performance improvements. Reisner will also talk about the software development roadmap for DRBD, LINSTOR, and the LINSTOR driver in CloudStack, including thoughts about online (live) migrating storage volumes between primary storage.
On Friday, 21 November, LINSTOR for CloudStack lead developer, Rene Peinthor, will host a workshop showing how to have highly available storage in CloudStack by using LINSTOR. The workshop will start from a cluster of freshly installed VMs. Peinthor will then take attendees through the steps of configuring the setup, and show VM live migration and failover tests in CloudStack.
You can learn more about the conference and its agenda at the CloudStack Collaboration Conference website.
The CozySummit Virtual 2025
CozyStack is a platform built on open source Kubernetes related technologies, such as Talos Linux, OVN, KubeVirt, and LINSTOR. CozyStack is a CNCF Sandbox project. By installing CozyStack on bare metal, you can create a platform-as-a-service for launching Kubernetes clusters, VMs, load balancing services, databases-as-a-service, and more. LINSTOR provides highly available persistent storage volumes in the stack.
At the CozySummit Virtual 2025 conference, LINSTOR for Kubernetes lead developer, Moritz Wanzenböck, will give a deep dive into the technologies that power the CozyStack storage infrastructure: LINSTOR and DRBD. Wanzenböck will show how these storage technologies integrate with virtualization and backup solutions, and show the stack in action.
The CozySummit Virtual 2025 conference takes place Wednesday, 3 December. You can find the conference agenda and learn more at the CozySummit Virtual 2025.
Conclusion
More enterprises are adopting open source platforms such as Kubernetes and CloudStack, for cost savings, to avoid vendor lock-in, for digital sovereignty, and other reasons. The LINBIT team continues to keep development pace with advances in these and other platforms while underpinning data within them through its proven storage software such as DRBD, LINSTOR, and related tools. The LINBIT team’s presence at conferences, particularly those within the open source community, are not only an opportunity to showcase the team’s latest developments, but also reinforce the team’s dedication to learning from and collaborating with the community.
