Clumio announces $75M Series D and 4X YoY growth in ARR


How LexisNexis achieved Amazon S3 data lake resilience at scale

“Clumio’s Instant Access is an important innovation, providing immediate access to our data that minimizes disruption to our customers.”
 Mark Seitter Senior Consulting Software Engineer

LexisNexis is a global provider of legal, regulatory, and business information and analytics, with a database containing over 144 billion records.

LexisNexis’ 144 billion records comprise one of the world’s largest online databases, and this database is in a constant state of change, adding approximately 1.2 million new records daily. LexisNexis uses AWS CloudFront Origin Groups to provide per-request failover for DR purposes, but was seeking a backup solution to ensure data resilience in case of an accidental deletion, code bug, or other data issue.

LexisNexis mandated a 15-minute RPO to minimize data loss, as well as a low RTO to ensure ongoing access to their data. Given the incredible scale and velocity of data, other solutions considered couldn’t meet this need, but Clumio was up to the task.

With Clumio, LexisNexis is able to give customers immediate data access while rehydration of the primary bucket takes place in the background. This was accomplished by integrating Clumio’s Instant Access feature with LexisNexis’ CloudFront Origin Groups, allowing them to swap in the Clumio backup endpoint for their primary region should a data loss occur.

LexisNexis is now meeting their 15 minute RPO, with a tested RTO of under three hours for their entire 26 billion object bucket, ensuring customers will have ongoing access to important data, no matter what.
