The real budget of a RAG: seven hidden costs
Re-indexing, access rights, evaluation, on-call, reversibility: the seven cost lines missing from every quote, and what they weigh over three years.
Insights
Technical writing, addressed to decision makers.
What we learn in the field: what works, what costs money, and the decisions we genuinely advise you to make.

Cloud and costs
What does your AWS bill really cost you?
The five lines that drift unnoticed, how to read a bill line by line, and the six levers that take a €3,200 monthly bill down to €1,420 without hurting service.

RAG: why your chatbot forgets your data
A language model does not know your procedures. How the indexing chain, document chunking and guardrails make the difference between a demo and a daily tool.
Operations
Preventive maintenance: the seven warning signs of a failure
A filling disk, a slowing service, a silently failing backup, an expiring certificate: the seven indicators we watch, and the threshold at which you must act.
Architecture
Custom software or off-the-shelf licence?
Total cost, dependency, reversibility, speed: the five questions that honestly decide between a market subscription, a specialised ERP and custom development.
Agents
Autonomous agents: the frame matters more than the model
A useful agent is not a free agent. Action scope, bounded toolbox, execution journal, human validation on sensitive actions: our design doctrine.
Data
Sovereignty and AI: what European regulation really says
Hosting, subcontracting, minimisation, logging. The questions to ask a supplier before signing — and the answers that should raise a red flag.
Artificial intelligence
What does a RAG really cost for an SME?
A RAG can be demonstrated in three days and takes three months to put into production. The five cost lines that make up the price, and the choices that divide the bill by two.
Operations
Useful monitoring: fewer alerts, more signals
An alert nobody reads protects nobody. The four questions that sort a wall of alerts, and the signals we watch instead.
Cloud and Terraform
Terraform on AWS: where to start in an SME
With no platform team: the five steps in order, remote state, the modules not to write yet, and the three mistakes that cost a week.
Sovereignty and AI
Choosing an AI provider in Europe: the checklist
Five questions separate a partner from a reseller: who owns the index, where queries run, which subcontractors are involved, reversibility, and how accuracy is measured.
