If you’d asked an IT professional whether object storage is any good for databases, the answer over most of the past decade or so would have been a resounding “no”.
The response would have been pretty obvious because databases, especially in busy and mission-critical environments, are subject to a lot of changes from a lot of users, either simultaneously or almost simultaneously.
Databases need IOPS (input/output operations per second) and they need some way of enforcing consistency of data, meaning block access SAN storage has long been the way to deliver that.
