## AI overview

Cloud CIRCUS migrated BlueMonkey's CloudFront log analytics from Amazon Athena to a self-managed ClickHouse environment. The move consolidated logs into a single table, improved query speed and automation, and reduced the time, complexity, and unpredictability of analytics costs as the SaaS company scaled across more than 2,000 customer websites.

"By migrating from Athena to ClickHouse, we've been able to save both time and costs. Most importantly, we no longer have to worry about expenses every time we run a query, which is a huge relief." Kyurin Shu, infrastructure engineer
