Create the mathematical and physical foundations for the technologies that will form a new information ecosystem, the Central Nervous System for the Earth (CeNSE), consisting of a trillion nanoscale sensors and actuators embedded in the environment and connected via an array of networks with computing systems, software and services to exchange their information among analysis engines, storage systems and end users.

Over the last couple years, we see an emerging data storage mechanism for storing large scale of data. These storage solution differs quite significantly with the RDBMS model and is also known as the NOSQL. The aim of this blog is to extract the underlying technologies that these solutions have in common, and get a deeper understanding on the implication to your application's design.

The Photos application is one of Facebook’s most popular features. Up to date, users have uploaded over 15 billion photos which makes Facebook the biggest photo sharing website. For each uploaded photo, Facebook generates and stores four images of different sizes, which translates to a total of 60 billion images and 1.5PB of storage. The current growth rate is 220 million new photos per week, which translates to 25TB of additional storage consumed weekly. At the peak there are 550,000 images served per second. These numbers pose a significant challenge for the Facebook photo storage infrastructure.

realStorage is meant to create a consistent API for the W3C Web Storage key/value store specification (i.e. work around browser bugs). It also adds some convenience functions to help flesh out the localStorage key/value API. And when Web Storage is not available, a Gears fallback is provided.

realStorage 2.0 is now officially released. For those that don't know, realStorage is a compatibility library that handles browser incompatibilities for the W3C Web Storage API as of August.
