    November 2023 - Today (2 years and 7 months)
    Implementation of a DataMesh architecture on Google Cloud Platform (GCP) for a space operator wishing to modernize and improve its data management. The objective is to adopt a decentralized approach where each domain manages its data with centralized governance and common standards. This aims to facilitate the management of large volumes of spatial data while ensuring security, scalability, and performance of Cloud services. Objectives include deploying a flexible and scalable GCP infrastructure, adopting Infrastructure as Code (IaC) via Terraform for automation, and managing identities, access, and data security for the different teams (DataMesh).

    The implementation includes configuring the GCP environment (integration of GKE, Cloud SQL, Bigtable). The IaC build with Terraform automates the creation and management of cloud resources, including service accounts, IAM policies, and organization rules for identity and security management. A shared Virtual Private Cloud (VPC) is deployed with subnets, firewall rules, and a router for better network segmentation and security.
