During the course of my work at present to build a Cloud based NAS , I came across the story of an upstart company called “Blackblaze” that engineered and built a cheap, petabyte scale cloud storage.
Their engineering and economics of the product is incredible. In my opinion, They are at the top of “Frugal Engineering” which perhaps reflects directly in the price of their service offering at $5/month/Computer for an unlimited backup & storage!
I thought I would share this information and would recommend anyone interested in Cloud computing & Storage systems to read their blog post here. They have opensourced the storage architecture needed to build such a product.
