+__A Deep-Dive Into the Integration of CloudStack and Ceph Primary Storage [Wido den Hollander]( https://www.linkedin.com/in/widodh/) — CTO, [Your.Online](https://your.online/)__
+
+This session provides a deep dive into integrating Apache CloudStack
+with Ceph as primary storage - widely considered a gold standard for
+organizations building reliable, open-source IaaS platforms. We’ll
+explore architecture, deployment patterns, and key design
+considerations for creating scalable and resilient cloud environments.
+
+Attendees will gain practical insights into performance optimization,
+high availability, and operational best practices, along with lessons
+learned from real-world experience of a decade working with both
+technologies.

+__Digital Sovereignty in Practice: Building a High-Performance Cloud Without Vendor Lock-In [Swen Brüseke](https://www.linkedin.com/in/swen-br%C3%BCseke-391912193/) — CEO, [ProIO]( https://www.proio.com/)__
+
+Digital sovereignty is no longer just a buzzword; it has become a
+critical survival strategy for enterprises. But how do you build a
+cloud platform that is performant, cost-effective, and truly free from
+vendor lock-in? proIO has been consistently relying on Apache
+CloudStack since 2013. In this session, we will discuss why private
+clouds are more relevant than ever in the current global climate and
+how we push our platform to its limits as "heavy users" to deliver
+premium Managed Hosting. We will provide technical insights into our
+stack—from Linbit-based Hyperconverged Infrastructure (HCI) to our
+strategic partnership with ShapeBlue. Join us for a look behind the
+scenes from a CloudStack Committer’s perspective on the synergy
+between Open Source DNA and Enterprise requirements.
+
+*__12:10 – 12:40__*
+
+__LINSTOR as CloudStack Primary Storage: From Theory to Production War Stories [Rene Peinthor](https://www.linkedin.com/in/rene-peinthor-588b50339/) — Software Engineer, [LINBIT](https://linbit.com/)__
+
+This talk will start with a theoretical introduction of LINSTOR-SDS
+and will then dive into common production problems and stories we
+encountered and how to avoid them.
+
+*__12:40 – 13:40__*
+
+__Lunch Break__
+
+## Afternoon Sessions
+
+*__13:00 – 15:00__*
+
+Apache CloudStack for Beginners – Workshop A dedicated hands-on
+workshop designed for newcomers and those looking to strengthen their
+Apache CloudStack fundamentals. Participants will learn core
+architecture concepts, deployment basics, and practical operational
+guidance.
+
+*__13:40 – 14:10__*
+
+__Kubernetes is Not the New VM: Choosing the Right Abstraction for Modern Infrastructure [Stoil Stoilov](https://www.linkedin.com/in/stoil-stoilov/) — Senior DevOps Engineer, [StorPool Storage](https://storpool.com/)__
+
+In this talk, we challenge the “Kubernetes replaces VMs” myth and
+instead present a practical, operator-focused framework for deciding
+when to use Kubernetes and when to rely on virtual machines—especially
+in CloudStack environments. We will explore the fundamental
+differences between VMs and containers, including isolation
+boundaries, lifecycle management, networking models, and operational
+complexity. Through real-world scenarios, we’ll highlight where
+Kubernetes excels (cloud-native workloads, horizontal scaling,
+stateless services) and where VMs remain the better choice (stateful
+systems, legacy applications, strong isolation requirements,
+predictable performance). Finally, we’ll discuss how CloudStack users
+can combine both paradigms effectively—using VMs as the foundation and
+Kubernetes as a workload layer—rather than treating them as competing
+technologies.
+
+*__14:20 – 14:50__*
+
+__Safeguarding Apache CloudStack – Data Protection & Recovery Powered by Commvault [Ruben Renders]( https://www.linkedin.com/in/rubenrenders/) — Solutions Director, MSP & Sovereign Solutions, [Commvault](https://www.commvault.com/)__
+
+Explore how Commvault enhances Apache CloudStack with enterprise-grade
+data protection and recovery. Attendees will gain insight into
+Commvault’s broader portfolio while learning how to build a strong
+foundation for cyber resilience; supported by a demo and practical
+implementation blueprints.
+
+*__14:50 – 15:15__*
+
+__Coffee Break__
+
+*__15:15 – 15:45__*
+
+__CloudStack Multisite Networking [Noa Omer](https://www.linkedin.com/in/noa-omer/?originalSubdomain=nl) — Platform Engineer, [Cyso Group](https://cyso.com/en/)__
+
+In this session, Noa, Platform Engineer at Cyso Cloud, presents how
+Cyso deploys Apache CloudStack to establish multisite networking
+across two geographically distributed regions. The presentation covers
+cross-region zone interconnectivity, network fabric design, and
+routing configuration, alongside an honest account of the operational
+complexities encountered and the outcomes achieved.
+
+*__15:55 – 16:30__*
+
+__From VMware to CloudStack/KVM: A Structured Migration Strategy with Minimal Downtime [Ingo Jochim](https://www.linkedin.com/in/ingo-jochim/?locale=en_US), Head of Cloud Architecture & [Prashanth Reddy](https://www.linkedin.com/in/prashanth-mandadi-reddy/), Cloud Architect — ShapeBlue__
+
+As organizations look to reduce vendor lock-in and regain control over
+their infrastructure, migrating from VMware to open-source platforms
+like Apache CloudStack with KVM is becoming an increasingly relevant
+path. However, such migrations require careful planning to ensure
+reliability, continuity, and minimal disruption to workloads.
+
+This talk presents a structured, practical approach to migrating
+virtualized environments from VMware to CloudStack/KVM. It covers the
+full migration lifecycle, starting with environment discovery and
+detailed documentation, followed by planning and technical
+preparation. Attendees will learn how to validate the migration
+process through controlled
+
+test migrations before executing large-scale mass migrations.
+
+A key focus of the session is achieving migrations with minimal
+downtime. The presentation will explore techniques such as warm
+migration, performing an initial bulk data transfer in advance, and
+executing a short cutover window using delta synchronization to
+transfer only the final changes.
