Terms, explained.

A systematic evaluation of the technical, financial and organisational steps required to leave a cloud provider and migrate data and services to another provider or onto your own infrastructure.

Technologies such as Docker and Kubernetes that package applications into isolated, portable units (containers), enabling consistent operation across diverse infrastructures.

Implementing technical requirements that ensure data is only stored and processed in specific geographic regions or jurisdictions.

Moving data and applications back from the cloud onto self-operated infrastructure, often motivated by cost optimisation or sovereignty requirements.

A review of whether IT systems, processes and data flows meet the requirements of the EU General Data Protection Regulation (GDPR).

A technology that defines virtual geographic boundaries to restrict access to data or services to particular regions, e.g. EU data centres.

An approach where IT infrastructure (servers, networks, databases) is managed and provisioned through machine-readable configuration files instead of manual processes.

Modernising and migrating legacy IT systems into a cloud environment, often combined with reworking the architecture.

A migration approach in which existing applications are moved from one environment to another (e.g. from a US cloud provider to an EU provider) without significant changes.

Professional support and operation of self-hosted software by an external provider, including maintenance, updates and monitoring, without giving up control of your data.

Deliberate use of multiple cloud providers to reduce dependencies, increase resilience and use the best-of-breed services from each provider.

Software whose source code is publicly accessible and may be inspected, modified and redistributed by anyone. Promotes transparency, independence and collaborative development.

A structured workshop in which we jointly evaluate which existing proprietary tools and services could be replaced with open-source alternatives.

Software or technology whose source code is not publicly available and which can only be used under the vendor's terms. The opposite of open source.

An approach in which IT solutions are designed so that they are not tied to one specific provider and can be moved at any time.

Retrieval-Augmented Generation: an AI architecture where language models generate answers based on your own documents and data sources rather than relying solely on the model's internal knowledge.

Replacing proprietary Software-as-a-Service products with self-hosted open-source alternatives in order to regain control over data and functionality.

AI models and infrastructures operated under European control, on your own hardware or with EU providers, without training or input data flowing to US hyperscalers.

The planning and architecture of cloud infrastructures operated entirely under European jurisdiction, ensuring digital sovereignty.

A situation where a company is so dependent on a specific provider that switching to another would involve substantial effort, cost or risk.
