FAQs

Clastix is an enterprise Kubernetes platform company that specializes in hosted control planes and hard multi-tenancy. Rooted in Italian engineering, it helps cloud providers, managed service providers (MSPs) and platform teams run secure, isolated and cost-efficient infrastructure at scale. Customers include NVIDIA and Mistral AI.

Clastix offers three main products: Capsule, Kamaji and kMetal. Together with Clastix Care support and Clastix Ready professional services, they cover everything from open-source adoption to enterprise-grade deployments.

Capsule is an open-source Kubernetes multi-tenancy tool that works at the namespace level inside a single cluster. It groups namespaces into a "Tenant" and enforces automated quotas, Network Policies and RBAC across them. It is a good fit for isolating internal teams where resource efficiency matters most.

Kamaji is the Kubernetes hosted control plane from Clastix, available as open-source software. It focuses on the core functionality needed to manage and operate Kubernetes environments efficiently. Production users who need enterprise-grade support can add a dedicated Kamaji support plan.

kMetal is a turnkey, enterprise-grade Kubernetes solution that extends Kamaji and Capsule. It adds features, stability and management capabilities for large-scale production environments. It is proprietary software, so it includes a software license plus a Support and Maintenance service that covers all Kamaji support features and the kMetal-specific capabilities.

Capsule and Kamaji are open source and licensed under Apache 2. kMetal is proprietary to Clastix SRL and requires a valid, paid software license.

Clastix Care covers Capsule, Kamaji and kMetal with guaranteed SLAs. Deliverables include:

• Stable releases with Long Term Support (LTS).
• Security acceptance testing of the code before release, using standard industry processes and tooling.
• A monthly vulnerability report, with descriptions compliant with the NIST NVD format.
• Prompt notification before public disclosure of any security concern that may affect the supported software.
• Proactive CVE resolutions, with a strong commitment to fix critical issues before public disclosure whenever possible.
• Continuous delivery of fixes and improvements for stability and reliability in production.
• Feature prioritization, so new features can match your requirements and business goals faster.
• Release upgrade assistance and guidance.
• Access to a private Slack channel for technical questions.
• Monthly Office Hours.

The plan includes 3 major upgrades per year and unlimited minor upgrades, with assistance and guidance to keep each transition smooth.

Monthly Office Hours are a scheduled online meeting every month, lasting 45 minutes. You can use them to discuss questions, updates or progress on the support services and to address specific customer project needs.

Yes. Both are open source, so you can run them without a paid agreement. Without support, maintenance works as follows:

• Community-driven fixes: the community handles most software issues. Clastix helps when possible, but no SLA guarantees it.
• Prioritized security: security patches go to premium subscribers first. Once the issue is fully addressed, Clastix releases the fix and notification to the wider community.

No. The no-support model applies only to the open-source products, Capsule and Kamaji. kMetal is a proprietary enterprise product available only through a paid software subscription.

Clastix commits to the following response times for critical environments:

The offering assumes a standard 3-tier escalation process. Layers 1 and 2 sit with the customer, and Layer 3 is handled by Clastix:

Clastix Enterprise Support covers Layer 3 only. The customer is responsible for implementing and operating the Layer 1 and Layer 2 process, using properly trained datacenter personnel who can identify the source of a problem and pinpoint the affected area of the infrastructure.

Clastix Ready is a set of Professional Service Packages that help customers adopt and use Clastix technology with confidence. They cover post-sales and delivery across the full implementation lifecycle: design, system integration, setup, training and, optionally, customization.

1. Design: a High-Level Design (HLD) defines the overall solution architecture, covering dimensioning, deployment, high availability, disaster recovery, backup and external integrations such as storage and load balancing. A Low-Level Design (LLD) is the detailed blueprint for physical implementation, confirming infrastructure readiness and technical prerequisites.
2. Implementation: physical installation and deployment of the Clastix solution based on the approved LLD, including configuration, testing and formal delivery.
3. System integration: making the deployed solution work smoothly with existing datacenter components such as storage, hypervisors and monitoring.
4. Training: training for customer technical staff, tailored in length and depth to their existing skills.
5. Customizations (optional): an optional module for unique requirements that standard, out-of-the-box Clastix features do not meet.
