Joe Williams discusses how distributed systems, cloud computing and automated configuration management affect system’s availability. He exemplifies with a database service built on CouchDB, Erlang, Chef, all running on EC2.
In a world of services, RDBMS are not the solution to every problem. Document Oriented Distributed Databases try to solve this and add a new way of storing documents. CouchDB (written in Erlang) is in its alpha stage and evolving on a regular basis. InfoQ caught up with Anthony Eden who is implementing the same concept in Ruby with RDDB.
