Solution Patterns

Profile & sector

National operator owning an under-used data centre (postal, telecom or public operator).

Core challenge

The hardware exists, but there is no software layer to sell it as a cloud: no self-service, no billing, no sovereignty proof.

Architectural approach

• an ESSINGAN Spoke installed on the existing hypervisors through Lithos plugins;
• landing zones, managed Kubernetes, identity, usage billing and a client portal;
• the operator acquires its platform once (Wholesale) and keeps 100 % of its raw infrastructure revenue plus 70 % of the software value added;
• revenue grows as its own certified teams take over delivery.

Profile & sector

State that has already built government data centres.

Core challenge

Ministries cannot yet consume that capacity as services, and the State needs national engineers able to run it alone.

Architectural approach

• one Spoke per pilot ministry and a factory for environments;
• a repatriation factory and a government software factory;
• enclave protection for identity and public-finance data;
• a national excellence track (SPITZCRAFT) with a contractual autonomy KPI;
• a federable reference architecture for neighbouring States.

Profile & sector

Start-up building transaction-linked contributions for the general interest.

Core challenge

Merchants, citizens and institutions must be able to verify that each contribution followed the announced path, without exposing merchants’ sales data. Money must never transit through the platform.

Architectural approach

• the start-up’s own substrate on a European host;
• three identity audiences;
• a signed, tamper-evident contribution ledger;
• confidential processing of merchant data (aggregates only);
• post-quantum signatures for long-lived evidence;
• money moved only by a licensed payment institution.

Profile & sector

Regional publisher of document-management and electronic-archiving software.

Core challenge

Its applications are sovereign by intent but run on whatever servers the client has, with no industrialised platform and no proof. Its archives must remain legally valid for decades.

Architectural approach

• the publisher’s SaaS on its own ESSINGAN substrate;
• client substrates sold with the application;
• post-quantum sealing of archival evidence;
• joint “sovereign office” offers with ESSINGAN Workspace.

Profile & sector

Any fleet that scales down off-hours (enterprise, operator or State).

Core challenge

Capacity freed at night and weekends (about 64 % of the week) is lost, while AI inference needs compute.

Architectural approach

AMADIRO harvests idle capacity and places on-demand or deferred inference jobs on it, according to data classification (sensitive data in TIFAE enclaves only), open local models and energy windows. Business workloads always pre-empt. Every run is attested in the Sigil chain.
