High-Availability OpenStack, Native Kubernetes & Hard Multi-Tenancy
The Enterprise Sovereign Cloud for GitOps, Zero Lock-In & Private AI Infrastructure
Eliminate proprietary vendor lock-in, unpredictable egress penalties, and foreign CLOUD Act exposure. Deploy pure upstream CNCF Kubernetes clusters (Cluster API & Magnum), hardware-isolated KVM hypervisors, wire-speed OVN Geneve Layer-3 VPCs, all-NVMe Ceph distributed storage, and sovereign vLLM AI model serving—fully automated via HashiCorp Terraform.
From Bare Metal to Orchestrated Workloads
Explore the multi-layer architectural transition. Every compute node is anchored in hardware root-of-trust, isolated via KVM and OVN micro-segmentation, and orchestrated with pure upstream Kubernetes.
Physical Compute & DPU SmartNIC Fabric
Enterprise dual-socket AMD EPYC / Intel Xeon host nodes with PCIe Gen5 NVMe arrays, CPU AES-NI line-rate hardware offloading, and 400G Leaf-Spine BGP EVPN fabric.
Type-1 KVM & OVN Geneve Boundaries
Hard hypervisor virtualization boundary with hardware-enforced CPU pinning (NUMA), Virtual TPM 2.0 (swtpm) measured boot, OVN Geneve overlay encapsulation, and local Barbican KMS key escrow.
OpenStack Kolla & Distributed Ceph NVMe
Zero-SPOF microservice control plane with Active-Active Galera DB, Keystone 2FA RBAC, Ceph Messenger v2 in-transit wire encryption, and Ceph NVMe storage ring with self-healing 3x CRUSH map replication.
Orchestrated K8s Containers & Sovereign AI
CNCF Upstream Kubernetes clusters, Cilium WireGuard transparent mesh encryption, vLLM dynamic Multi-LoRA model inference, Qdrant vector databases, and cryptographic volume erasure.
The Engine Room
Technical advantages engineered from bare-metal up for resilience, performance, and true sovereignty.
Hard Multi-Tenancy
True VPCs, Not Just VPS.
Every instance is isolated via KVM hypervisors. Build complex Layer 3 topologies, floating IPs, and private subnets powered by OVN.
Upstream Kubernetes
No Walled Gardens.
Deploy fully compliant, unmodified K8s clusters. Equipped with Cilium eBPF CNI with transparent WireGuard mesh encryption, Virtual TPM 2.0, and pure upstream CNCF APIs.
Ceph NVMe Storage
Distributed by Default.
Cinder CSI is baked into every cluster. When your pod requests a volume, our NVMe Ceph cluster provisions it instantly with Cinder LUKS AES-256 envelope encryption, Barbican KMS key escrow, and cryptographic shredding on volume deletion.
AI Inference PaaS & Model Foundry
Zero token markup. Zero API vendor lock-in. 100% in-country data residency. Deploy and scale open foundation models, enterprise RAG, and frontier MoE batch inference on your sovereign Kubernetes cloud.
Model Foundry
Curated, verified open foundation models—including DeepSeek-R1, Llama 3.3, and Qwen 2.5—ready for 1-click deployment. Features automated SafeTensors verification, Hugging Face pull-through caching, and high-speed CephFS weight caching that eliminates cold-start penalties.
vLLM Serving & Multi-LoRA
High-concurrency model serving powered by vLLM and KubeRay's RayService CRD with PagedAttention, continuous batching, and chunked prefill. Dynamically switch between dozens of fine-tuned LoRA adapters on a single base model pod with zero restart downtime.
Enterprise Vector DBaaS (Qdrant)
Production-grade vector search engineered in Rust for enterprise RAG and semantic search. Uses on-disk NVMe vector indexing with 90% memory-saving scalar quantization, native hybrid retrieval (dense embeddings + BM25 sparse tokens), and interactive collection dashboard.
Frontier Batch & Observability
Run massive 284B–744B frontier MoE models (DeepSeek-V4, GLM-5.2) with NVMe expert offloading via Colibrì and Kubernetes Kueue priority queuing. Full telemetry via self-hosted Langfuse captures real-time Time-to-First-Token (TTFT), token billing, and prompt versioning.
Why Sovereign AI PaaS Matters
When calling US hyperscaler AI endpoints, your proprietary prompts, confidential enterprise data, and embeddings leave your national jurisdiction. Okustera executes 100% of inference, weights caching, and vector indexing inside your isolated tenant VPC—ensuring strict data residency, privacy, and full tenant isolation.
Production Solutions & Isolation Standards
Battle-tested reference architectures designed for enterprise scale, agentic AI workflows, and zero-loss financial data resilience under strict European multi-tenant controls.
Autonomous Agentic AI Workflows
Run multi-agent LLM systems with extreme throughput and zero foreign cloud exposure. Agents query an encrypted Qdrant vector knowledge base, perform high-speed tool calls against local APIs, execute untrusted Python code inside gVisor sandboxed micro-containers, and route completions through vLLM with dynamic Multi-LoRA adapter switching.

Total Jurisdiction Control.
Zero Foreign Exposure.
Unlike US hyperscalers whose IAM telemetry, metadata, and support planes routinely transit foreign jurisdictions—subjecting customer workloads to the US CLOUD Act and FISA 702 extraterritorial subpoenas—Okustera is engineered specifically for strict in-country data residency.
Guaranteed Physical Residency
Compute instances, Ceph NVMe block storage, and database WAL replication archives physically never leave your selected datacenter or national borders.
Self-Contained Local Control Plane
Keystone IAM, Barbican KMS, and APISIX operate 100% autonomously on your bare metal—zero external SaaS dependencies or phone-home beacons.
European Sovereign Jurisdiction
Engineered for European healthcare, banking, defense, and public sector tenders requiring verifiable national data isolation.
Open Standards & Hardened Security
Engineered with defense-in-depth isolation across compute (gVisor/KVM), networking (OVN/WireGuard), and storage (LUKS AES-256).
Multi-Region & Multi-Country Expansion
Scale seamlessly from RegionOne to RegionTwo across international borders with autonomous local control planes and zero cross-border leakage.
