AI Assistant: buy a solution, build it, or combine both?
The right choice does not depend on the number of features. It depends on what differentiates the company, what must remain under control, and what a provider can sustainably handle.

MCP, A2A and AGNTCY: understanding the interoperability of AI agents in 2026
Not all agentic protocols solve the same problem. Stacking them without a clear need increases the attack surface and operational complexity.
MCP in business in 2026: architecture, authorization, governance, and migration to the 2026-07-28 specification
MCP standardizes the connection between AI applications, data, and tools. It does not standardize trust, business rights, or governance: these responsibilities remain to be designed.
Document Intelligence in 2026: beyond OCR, extracting structure, tables, and evidence
Plain text is not enough when an amount depends on a column, a signature must be located, or a quotation must return to a specific area of the document.
DRP and BCP of a web application: defining RTO, RPO, backups, and crisis scenarios
A DRP is not a document filed in a folder. It is a capability tested to restore a service, its data, and its dependencies within a timeframe accepted by the business.
Choosing an AI model in 2026: GPT-5.6, Mistral Medium 3.5, and specialized models without falling into the benchmark trap
The best general model is not necessarily the best component of your application. In 2026, selection must compare specific versions on real tasks, then plan routing, canary, fallback, and re-evaluation.
LLMOps: version, monitor, and operate generative AI applications
A generative application changes when the model, the prompt, the corpus, the tools, or the policies evolve. The operation must be able to attribute each result to this configuration.
Multisite, multi-brand, and multilingual platform: architecture, governance, and SEO
Pooling does not mean making all sites identical. A good platform shares what needs to be shared and makes local margins of freedom explicit.
Application maintenance contract: SLA, TMA, on-call duty and budget without gray area
A good maintenance system does not promise that nothing will break down. It defines how incidents are detected, qualified, restored, and prevented from recurring.
Development agents in 2026: accelerating delivery without degrading architecture or security
A code agent can modify multiple files, run tests, and prepare a pull request. Its speed makes architectural and review safeguards more important, not less.
Changing IT service provider: the reversibility checklist to avoid losing code, data, or access
Reversibility is not a document requested on the last day. It is the client's permanent ability to regain their assets, their data, and their decision-making autonomy.
RAG in business: moving from POC to a reliable, secure, and measurable assistant
A production RAG is not judged by a few convincing answers. It must know its sources, respect rights, measure its errors, and properly refuse when evidence is lacking.
