Yoann Jospitre enhanced the documentation for the VMware vSAN stretched cluster reference architecture in the oracle-devrel/technology-engineering repository. He focused on updating the README to provide clear, actionable guidance for deploying stretched clusters across Oracle Cloud Infrastructure regions, addressing outdated links and removing duplicate content to streamline the onboarding process. Using Markdown and technical writing skills, Yoann improved documentation hygiene and maintainability, ensuring that future regional expansions are supported with accurate reference material. His work reduced deployment friction and support overhead by delivering a canonical resource that enables teams to deploy multi-region VMware vSAN clusters with greater confidence and efficiency.
