Leading Open Source Cloud PlatformsTier 1

OpenStack

• Most mature, enterprise-ready open source cloud platform
• Comprehensive IaaS functionality with modular architecture
• Key components: Nova (compute), Swift (object storage), Neutron (networking)
• Strong adoption in telecommunications, research, government sectors

Kubernetes

• "Cloud in a box" container orchestration platform
• Not a complete cloud solution but foundational component
• Cross-cloud compatibility (GKE, EKS, AKS)
• Key features: exceptional scalability, self-healing, declarative configuration
• Facilitates workload portability between cloud providers

Tier 2

Apache CloudStack

• Enterprise-grade IaaS platform
• Single management server architecture
• Straightforward installation, less architectural flexibility
• Mature and stable for production

OpenNebula

• Lightweight virtualization management
• Lower resource requirements than OpenStack
• Strong integration with VMware and KVM environments

Emerging Platforms

Rancher/K3s

• Lightweight Kubernetes distribution
• Optimized for edge computing
• Simplified binary deployment model
• Growing edge computing ecosystem

OKD (OpenShift Kubernetes Distribution)

• Upstream project for Red Hat OpenShift
• Developer-focused capabilities on Kubernetes

Geopolitical & Strategic Context

• Growing US-EU tension creating market opportunity for European cloud sovereignty
• European emphasis on data privacy, rights-based innovation, and technological independence
• Potential bifurcation between US and European technology ecosystems
• Rising concern about Big Tech's influence on governance and sovereignty
• European cloud providers positioned as alternatives emphasizing human rights, privacy

Technical Independence Challenges

• Processor architecture dependencies (Intel/AMD dominance)
• European Processor Initiative and SiPearl developing EU alternatives
• Full software stack independence remains aspirational
• Network equipment supply chain complexities
