How Calm achieved better production stability with EKS on AWS.

Challenge: The company behind the leading meditation app found itself in a decidedly non-calming situation when an outage had catastrophic consequences.

Impact: Calm benefited from improved stability, reliable networking, and elimination of costly outages. In the months since, the company has been able to easily absorb significant revenue growth without performance issues.
