About versitygw
VersityGW (the Versity S3 Gateway) is an Apache 2.0 licensed, Go based translation service that presents existing storage — a generic POSIX filesystem, Versity's open source ScoutFS, Azure Blob Storage, or another S3 server — through a standard S3 API, and it is aimed at teams that already run storage infrastructure and want S3 compatible access to it without migrating data into a separate object store.
