Disaster Recovery – RPO and RTO RPO = Recovery Point Objective RTO = Recovery Time Objective kai-waehner.de | @KaiWaehner | Serverless Apache Kafka and Spark across the Globe

Use Cases for Hybrid and Multi-Cloud Data Lakehouses • Disaster Recovery and High Availability: Create a disaster recovery cluster, and fail over to it during an outage. • Global and Multi-Cloud Replication: Move and aggregate data across regions and clouds. • Data Sharing: Share data with other teams, lines-of-business, or organizations. • Data Migration: Migrate data and workloads from one cluster to another (like from legacy on-premise data warehouse to cloud-native data lakehouse). kai-waehner.de | @KaiWaehner | Serverless Apache Kafka and Spark across the Globe Data Replication at Rest or in Motion?
