Overview Have you ever imagined the world with an infinite amount of storage available and accessible to everyone? A place where everyone in the world can easily access their books/music/photos/video/any data from anywhere at any time via any means (e.g., mobile phones, tablets, personal computers (PCs), smart devices, etc.). Did you ever desire a universally accessible storage system to record all the knowledge known to mankind, to keep all the books/music/videos ever created, or to store all the data collected from all the scientists in the world for them to collaborate upon? Do you want to be part of a team that strives to bring these to reality? If so, the Microsoft Azure Storage team is what you are looking for. We are building Microsoft’s cloud storage solution—Microsoft Azure Storage—which is a massively scalable, highly distributed, ubiquitously accessible storage system, designed to scale out and serve the entire world.
