Migration

At Siteimprove, Sébastien Requiem led a 15-person DevOps team, orchestrating a seamless migration from a multi-region, on-premise VMware infrastructure to a multi-region/multi-account AWS cloud environment. Utilizing the 6R strategy, he transitioned over 100 Kubernetes workloads, implemented infrastructure as code via Terraform, and achieved a 30% cost reduction through techniques like Spot Instances. Key achievements include successful migrations of VMs, databases, and networks, implementing an infrastructure-as-code model, and introducing 'Just-in-time' permissions elevation. His technical expertise spanned Kubernetes, Docker, AWS, Terraform, Azure AD, Ansible, and more.
