S3 Is Showing Its Age

S3 is falling behind its competitors in terms of features such as compare-and-swap operation, multi-region buckets, and object appends. These missing features are becoming a bigger problem as new infrastructure relies on object storage as the primary persistence layer. The decision to abandon or embrace S3 depends on the system's use cases and design goals. Preconditions on S3 and a unified S3Express One Zone API would make this decision easier.
