Reduce bandwidth costs with dm-cache: fast local SSD caching for network storage
How we cut AWS bandwidth costs 95% with dm-cache: fast local SSD caching for network storage The bandwidth billing challenge When deploying infrastructure across multiple AWS availability zones (AZs), bandwidth costs can become a significant operational expense. Some of our Upsun infrastructure spans three AZs for high availability, but this architecture created an unexpected challenge with our Ceph-based storage system. Since Ceph distributes data across the cluster and AWS bills for inter-A
