A Complete, Ready-To-Use Offering

High-Performance Private Infrastructure

Exaion delivers custom private cloud environments, hosted either in its own data centers or on the client’s premises, with a high level of isolation, availability, and performance. The infrastructure is built on next-generation hardware optimized for intensive workloads, including AI and HPC. It natively integrates best practices in security, monitoring, and resilience, and can scale as needed. A fully automated on-premise deployment option is also available for turnkey implementation.

Enterprise AI PaaS

Exaion’s managed AI stack enables the deployment and operation of artificial intelligence models (LLMs, vision models, agents, etc.) in a secure, interoperable, and controlled environment. It offers advanced features such as high-throughput inference, retrieval-augmented generation (RAG), fine-tuning, workflow management, and detailed performance monitoring. A unified API Gateway simplifies access to multiple models while ensuring granular access control, logging, and full observability.

Open Source Orchestration and Automation

Exaion relies on a proven open source foundation, OpenStack for IaaS and Kubernetes for PaaS, to ensure technological independence, interoperability, and infrastructure scalability. This robust base enables the orchestration of complex services, management of diverse workloads, and automation of key processes (CI/CD, security, monitoring). It is enriched with ready-to-use managed services (databases, object storage, observability, etc.) and governance through integrated security policies.

Energy Efficiency and Responsible Infrastructure

Exaion’s infrastructure is designed to combine performance with energy efficiency. By using refurbished hardware, immersion cooling techniques, and exclusively low-carbon energy sources, the environmental footprint of cloud operations is significantly reduced. Waste heat is recovered through local loops, and energy consumption and CO₂ emissions are continuously monitored. Exaion adopts an eco-design approach from the ground up.
