What is OChK Stack?
OChK Stack is a solution that enables you to design and comprehensively manage a sovereign cloud environment, giving you full control over processed data while reducing costs and project-related risks.
It is based on our trusted, proprietary OChK Platform and
open-source software.
We provide complete, end-to-end delivery—including both the hardware layer and fully-configured software. The entire environment can be deployed in your infrastructure within just a few weeks.
What does it actually mean?
About OChK Platform
The OChK Platform is a public cloud environment built and operated by our team of experts. Its flexible architecture supports non-standard use cases and allows you to combine services from different vendors, avoiding vendor lock-in.
It can also serve as an orchestration layer for your private cloud, integrate into hybrid models, or act as a Disaster Recovery Center.
An infrastructure designed exclusively for one organization eliminates risks related to shared environments.
Integration with your private infrastructure minimizes the risk of unauthorized access and protects against external intrusions.
The ability to exercise full control over your own security—from access policies to encryption and other protection measures.
OChK Stack follows a compliance-by-design approach—it supports organizations in meeting the latest requirements around data protection, cybersecurity, and AI governance.
By ensuring that all data is processed exclusively within the European Union, OChK Stack guarantees GDPR compliance. The use of advanced security mechanisms makes it a suitable environment even for companies operating in sectors classified as essential or important under the NIS2 directive. In the context of the AI Act, which emphasizes not only security but also auditability, OChK Stack provides a secure and controlled environment for training and deploying AI systems. Aligned with the principles of the Data Act, it supports infrastructure component portability, promotes interoperable cloud models, and strengthens users’ technological sovereignty.
Who is it for?
OChK Stack is built for organizations that prioritize local data residency, full control over their IT environment, and technological independence from foreign-licensed solutions. It’s particularly well-suited if you:
operate in a highly regulated sector (e.g. finance or healthcare) and must comply with DORA, NIS2, or similar frameworks,
process sensitive data and want to store it locally,
want to leverage the cloud potential, but your business profile and processes (e.g., production lines) prevent you from using public cloud,
rely on open-source software and seek greater operational flexibility while optimizing costs,
operate in a low-margin, highly competitive market where efficiency and independence are key,
want to train proprietary AI models in a secure, high-performance environment.
Scope of support and capabilities
OChK Stack can be tailored to your needs—both in terms of scale and technology stack. It supports gradual scaling—from core infrastructure elements such as virtual machines, storage, and virtual networking, through container environments and managed databases, up to the most advanced components like artificial intelligence and machine learning.
GenAI solutions demand significant computing power, especially during model deployment. Dedicated GPU servers are the most effective way to handle this need. That’s why OChK Stack leverages next-generation GPUs that accelerate:
- training of ML and deep learning models,
- inference for large language models (LLMs),
- real-time processing of images, video, and audio.
By incorporating GPUs, OChK Stack becomes an AI-ready cloud platform—fully optimized for building and running complex AI/ML solutions.
The OChK Stack architecture offers three tiers of advancement, enabling you to expand services as needed. Each tier includes backup creation, storage and management (BaaS), monitoring, logging, and support from our Security Operations Center (SOC) team.
Benefits
Local data residency
All services within OChK Stack run on servers physically located in Poland—ensuring local data residency requirements.
Enterprise-grade security
Full resource isolation, access and encryption policies, and integrated key management keep your data protected from unauthorized access.
Technological independence
Freedom from foreign-licensed technologies (including virtualization layers) eliminates vendor lock-in and offers greater flexibility.
Reduced data transfer risks
Local infrastructure allows you to avoid dependency on regulations outside your jurisdiction, ensuring full operational and legal sovereignty.
Unified and fully managed cloud environment
OChK Stack delivers a complete stack—from hardware to software—integrated with services like BaaS and security monitoring (SOC).
Transparent cost model
A fully subscription-based model helps you control, forecast, and optimize costs in line with your evolving business needs.
Intuitive environment management
A self-service, bilingual interface with built-in documentation and guidance streamlines your day-to-day cloud operations.
Expert support
Experienced consultants and certified engineers support you throughout deployment and daily operations.
Billing model
OChK Stack is available on a subscription model, which includes three billing levels corresponding to different ranges of available functions. This model allows for a gradual expansion of subscriptions as needs grow, while maintaining cost transparency at each stage. Each subscription level has a fixed monthly base fee, and any additional resource usage is billed flexibly according to actual consumption. Billing is invoiced monthly with a full consumption report to control and optimize costs. This model provides both predictability of expenses and flexibility to scale the service.
