DIGITRANS-CM (AGROCAM S.A.)

01. The Exam & African Constraints

Within the RNCP39765 certification exam (BC04 block 'Optimizing the SI with Cloud Computing'), the scenario places the team at CAMTECH SOLUTIONS S.A., a Cameroonian IT services company, on the DIGITRANS-CM mission for AGROCAM S.A.: replacing a 2009 monolith with a distributed, partially cloud SI. Traditional cloud architectures often fail in rural African environments where 2G/3G connectivity is spotty, field agents lose hours of operational logs during outages. And Cameroonian Law n°2010/012 restricts storing financial and HR data outside national borders, ruling out pure public cloud. Three days, in a team of three, to deliver a deployed application and a security report in front of a jury.

"Cloud architecture in Africa must be built for operational reality: intermittent connectivity, local data sovereignty, and offline resilience, and in a 3-day exam, every choice must be defensible."

02. Distributed Architecture & Offline Sync

I designed a 5-domain microservices architecture. The core innovation is the offline-first Supply Chain module: agents capture operations locally, while a background Redis worker manages deduplication and batch sync upon signal recovery. For batch auditing, Hyperledger Fabric ensures tamper-proof chaincode logging.

03. Exam Results & Takeaways

The exam was delivered within the allotted time: deployed application (hybrid AWS/Azure, Terraform, 5-stage CI/CD), technical documentation, security report (C25–C26) including the Hyperledger Fabric solution, and jury defense. Beyond the certification, it's the ability to make complex architectural decisions under deadline pressure, and defend them, that makes the exercise valuable.
