Explanation / Answer

1)

Cloud storage offers enterprise organizations the potential to dramatically decrease storage costs. Even so, there are some significant architectural differences between cloud storage and commonly used forms of local storage. These differences can make it challenging to use both local and cloud storage in a seamless manner. For those who might be new to cloud storage, its easy to assume that the only real difference between a cloud storage architecture and local storage is the storage location. Cloud storage differs from traditional storage in that most but not all, could storage offerings are built on an object based storage platform. The reason for this is that object based storage platforms an scale to massive levels of capacity and still deliver a very high level of performance.

Local storage tends to be block based. If an organization wants to use local and could storage in a seamless way, then they will need a way to translate between block and object storage.

Cloud storage is typically exposed as a web service. As such , standard storage protocols can’t be used to communicate with cloud based storage.
