After more than 10 years of experience with different evolutionary stages of timeseries monitoring systems and the growing need for metrics, we decided to replace database and file based solutions.
To store metrics for the long term, we rely on object storage technology to provide almost unlimited storage capacity in the backend.
The Object Storage is provided to us by multiple Ceph clusters. We are now also able to dynamically connect alternative storage locations, such as AWS and/or GCP, as needed.
