Splunk Inc. helps organizations ask questions, get answers, take actions, and achieve business outcomes from their data.

“Data is a strategic asset that organizations rely upon to operate and succeed. [...] It is imperative that organizations can trust their data as it is dispersed across teams and the cloud, but not every use case requires a decentralized ledger. We are excited about the potential for Amazon QLDB to provide a way to trust and verify the integrity of data without the complexity of operating a blockchain network.”

Klarna Bank

Klarna Bank

“We’re building our own banking platform from the ground up. We need this platform to be scalable, compliance-friendly, cost-effective, and have real-time capabilities. [...] To support this platform, we needed a cryptographically-verifiable and immutable transaction log at the core. We experimented with blockchain earlier this year and realized that a decentralized ledger did not really meet our needs as it was too complicated to operate and not sufficiently performant. With the release of Amazon QLDB we can leverage the AWS’s investment in a centralized ledger database to solve that problem, allowing us to focus our engineers on other, customer-centric aspects of the platform.”
