We’re pleased to announce that the CloudStack European User Group (CSEUG) 2026 will take place in the Netherlands on May 21st. This year’s event will be hosted by CBS (Centraal Bureau voor de Statistiek) in the Hague. The one-day technical event is open to cloud builders, infrastructure managers, and anyone interested in open-source cloud and IaaS technology.

As the first official CloudStack event of 2026, it is a great opportunity to start the year by learning, sharing ideas, meeting other operators and contributors, and exploring the latest developments across CloudStack and the wider open-source cloud ecosystem.

The CloudStack Collaboration Conference 2025 took place in Milan, Italy from November 19 to 21, bringing together CloudStack users, developers, and operators from across the global community. This annual in person event once again provided a valuable space for collaboration, knowledge sharing, and shaping the future of Apache CloudStack.

The Apache CloudStack project is pleased to announce the release of CloudStack Kubernetes Provider v1.2.0 that facilitates Kubernetes deployments on CloudStack.

It allows Kubernetes to dynamically allocate IP addresses and the respective networking rules on CloudStack to ensure seamless TCP, UDP and TCP-Proxy LoadBalancer deployments on Kubernetes.

This release contains various bug fixes and improvements. Some of the highlighted features include:

• Support for NetworkACLs for LB on VPC networks
• Support configuring source CIDR list
• ARM support for docker images
