 ## Rationales behind limits
 
 Most cloud infrastructure providers impose storage and bandwidth limits as a normal part of capacity planning and to ensure achievement of SLAs. In distributed and decentralized storage systems they are equally important, if not more so. Like any provider, the aggregate amount of available storage and bandwidth must be shared across all users. With a distributed and decentralized storage system like Storj, the storage and bandwidth are provided by a network of third parties running storage node software. One of the key aspects to success is the balance of supply and demand. If too many users over-utilize available resources, the user experience will be poor.
