What is an Object Storage File System? (known also as edge storage)
About
Object storage (or object edge storage) is:
- a file system for blob file (binary object) (ie object)
- that are distributed/replicated at several CDN location (at the edge)
File Identifier
In addition to the path, each object possesses a unique, generated and immutable identifier.
This identifier makes it possible to create a distributed file system that is:
- not constrained to a unique physical server.
- replication (Generally 3x to recover from fault)
They are mostly variations or fork of the Hadoop File System that are provided in the cloud (SAAS).
