Build a secure, open-source sovereign CloudStack cloud and infrastructure with Apache CloudStack. Retain authority over your data, technology and operations. Take back control of your cloud.
Apache CloudStack - the Foundation for Your Sovereign Cloud
Apache CloudStack is a mature, open-source cloud management platform for building and operating sovereign cloud infrastructure. It provides a control plane for orchestrating compute, storage and networking across private, public and regional clouds, while allowing your organisation to choose where the infrastructure is hosted, which technologies power it and who operates it.
Unlike proprietary cloud platforms, Apache CloudStack gives you freedom from restrictive licensing and dependence on a single infrastructure vendor. Its open architecture, multi-hypervisor support, native APIs, multi-tenancy and self-service capabilities make it a powerful foundation for a sovereign CloudStack cloud.
CBS Building a Sovereign Public Cloud with CloudStack
Apache CloudStack enables providers such as CBS Netherlands to build secure, scalable sovereign public clouds. The open-source platform supports multi-tenant services while keeping data, infrastructure and operations under local control – strengthening data sovereignty and reducing dependence on hyperscalers.
Your Sovereign CloudStack Cloud Architecture
Apache CloudStack enables organisations to build and operate sovereign public, private and hybrid clouds. It brings compute, networking and storage together within infrastructure that the organisation or an approved local provider controls.
A sovereign CloudStack cloud can run entirely within selected datacentres and jurisdictions, without relying on a vendor-operated control plane. CloudStack’s hierarchical architecture enables the platform to scale from a single cloud environment to tens of thousands of physical servers. This gives sovereign cloud operators the scale and automation of a modern cloud platform.
Zones
A Zone is the largest organisational unit within a CloudStack deployment. Typically, a datacentre (DC) implementation will contain a single Zone, but there are no hard and fast rules, and a DC can contain multiple Zones. A Zone consists of at least one Pod, and Secondary Storage which is shared by all Pods in the Zone. CloudStack Edge Zones are a specific type of Zone, designed to deploy lightweight resources in Edge environments.
Pods
A Pod typically relates to a discrete rack in a datacentre. Pods contain one or more Clusters and a Layer 2 switch architecture which is shared by all Clusters in that Pod. End users are not aware of and have no visibility of Pods.
Clusters
A Cluster is a group of identical Hosts running a common Hypervisor. It is the fourth-largest organizational unit within a CloudStack deployment. Clusters are contained within pods, and pods are contained within zones. The size of the cluster is limited by the underlying hypervisor, although CloudStack recommends smaller cluster size in most of the cases. A cluster consists of one or more hosts and one or more primary storage servers.
Primary Storage
Primary Storage is usually unique to each Cluster (although it could also be used Zone-wide) and is used to host the virtual machine instances. CloudStack is designed to work with all standards-compliant iSCSI and NFS Servers supported by the underlying Hypervisor, but many other storage solutions are also supported (SDS like Ceph, StorPool and LINBIT).
Secondary Storage
Secondary Storage stores virtual machine Templates, ISO images and Volume Snapshots. The storage is available to all PODs in a Zone. Secondary Storage uses the Network File System (NFS) to ensure it can be accessed by any Host in the Zone. For cross-zone secondary storage, S3 storage can be considered.

Deployment Scenarios
Apache CloudStack enables cloud service providers to build secure, scalable sovereign public cloud infrastructure within selected regions and jurisdictions. As an open-source cloud and virtualisation management platform, it supports multi-tenant services while giving providers control over data location, infrastructure, operations and security policies. This strengthens data sovereignty and jurisdictional control, reduces vendor lock-in and provides a locally operated alternative to hyperscalers. Providers can deliver the flexibility and scalability of public cloud while retaining authority over the underlying technology and operational model.
Apache CloudStack enables organisations to build secure, scalable sovereign private cloud infrastructure tailored to their operational and regulatory requirements. As an open-source cloud and virtualisation management platform, it provides full control over data, resources, security policies and infrastructure operations. This supports data sovereignty and jurisdictional control while reducing vendor lock-in and dependence on hyperscalers. Organisations gain the flexibility and efficiency of cloud computing while retaining complete authority over their private cloud environment.
Hybrid Cloud deployment with Apache CloudStack bridges the gap between public and private clouds, offering the best of both worlds. It enables organisations to balance cost-efficiency and scalability with security and control. With CloudStack’s Hybrid Cloud solutions, businesses can effortlessly move workloads between private and public environments as demands shift, maintaining optimal performance and flexibility. This unique capability ensures that organisations can respond to ever-changing business requirements, making the most of both public and private resources, and positioning them for success in a rapidly evolving marketplace.
