Experience
- SafranSenior DevOps Engineer / Cloud ExpertAVIATION AND AEROSPACEAugust 2024 - December 2024 (5 months)Malakoff, FranceContext:At Safran, a major migration project to the AWS cloud was carried out by a consultant team and sponsored by AWS. The objective was to transfer ~3500 VMs (RedHat and Windows) to AWS, due to Safran's datacenters having reached their limits. A datacenter decommissioning is therefore planned for 2026.My contributions:
- Creation of Shell and PowerShell scripts, for the post-launch step of VMs (Red Hat & Windows) on AWS : This step allows you to install and configure the necessary software on the servers. For example, installing agents CloudWatch, Flexera, Hurukai; the configuration of SSSD for SSH connection via LDAP AD; the hardening of the VM to meet the security standards established by Safran (mount folders, NetBIOS, firewall).
- Migration of on-prem VMs to AWS : Piloting migrations via AWS MGN until the cutover phase.
- Task automation : Setting up GitLab CI to automate the creation of AWS resources via Terraform (instance profile, bucket, IAM role, SSM Document).
- Training of subcontracting teams : Transfer of knowledge to Safran's subcontracting teams via training days led by myself. Sharing documentation detailing the steps to follow during migrations.
