What is Object Storage?
* All data, regardless of content type, is managed as objects
* Each object is stored in a bucket. A bucket is a logical container for storing objects
* Objects are stored in a single, flat structure without a folder hierarchy. This means that accessing individual objects is fast and easy
* Each Object is composed of object itself and metadata of the object. T his makes it easier to index and access data
* Object storage is quite common in cloud based storage scenarios with very high scalability and reliability
* While files and blocks are generally available to an operating system (by mount operation), object storage relies on standard HTTP verbs
