Achieving Amazon S3 data lake resilience at LexisNexis
summary
LexisNexis backs an 800‑terabyte S3 data lake with Clumio using S3 Inventory and S3 EventBridge + inventory for continuous capture, Lambda-driven processing in a dedicated Clumio account, and Terraform/CloudFormation onboarding. Continuous backup targets a 15 minute RPO; instant access exposes a read endpoint that eliminates full-copy restores and cuts RTO from days to hours — the team restores ~26–30 billion objects in about 2 hours 48 minutes. Cost optimizations include optional tagging and skipping delete events, reducing costs by ~48%.
