Lightning Talk: How a Global Logistics Company Migrated Clouds with Zero Downtime - Björn Wenzel, Schenker AG

During this session, Björn Wenzel, Head of DevOps Platform at a Germany-based global logistics company, will share how they migrated mutiple microservices from one cloud to another. Switching clouds never comes without challenges, especially considering their workloads communicate via synchronous and asynchronous HTTP(S) and Kafka requests across clusters and clouds. Björn will cover how the platform team implemented a migration factory for migrating workloads from one AWS Account and network to another AWS Account and network while ensuring there was no service disruption or compromised workloads. Linkerd played a critical role on the multi-cluster communication side. It was the first time Björn's team used a service mesh, and it allowed them to transparently migrate workload by workload to the new cloud. Since they had only exposed an mTLS encrypted tunnel across clusters, that setup solved a lot of security concerns, making the transition much smoother than expected. Join this session to learn more about Björn’s cloud-native journey with Linkerd, and the lessons he learned along the way.
