To understand where a user's assets are stored by Neebo.
A user's assets which compose Neebo datasets are stored by Neebo in Amazon Simple Storage Service, commonly known as S3. That is, the customer can benefit from the high scalability feature that such service offers.
In terms of security, assets belonging to different customers are stored in separate buckets. None of the customers' data is, in any way, kept in common areas.
Neebo keeps an internal representation of the assets it stores. Such information is referred to as metadata. Neebo uses Mongo DB system to store the information necessary to access its assets.
