Microsoft did this by sacrificing other features of object storage that S3 and GS had since the beginning, primarily performance, automatic scaling, unlimited provisioning and cross-sectional (region wide) bandwidth. Azure blob storage did not have parity on those features back in 2015 and data platform applications could not be implemented on top of it as a result. Since then they fixed some of these, but there are still areas where Azure lacks scaling features that are taken for granted on AWS and GCP.

Today I learned that there is a 5 PB soft capacity limit for Azure blob storage: https://learn.microsoft.com/en-us/azure/storage/common/scala...

Also, a 200 Gbps egress limit.

How does that compare to S3?

Mind you, at this scale the storage cost is about $15K/mo, so it would be cost effective to throw some developer time at the problem of scaling out between multiple storage accounts. Or just call support to have the soft limit cap raised…
