DistOS-2011W Cassandra and Hamachi

In the beginning

The Internet has seen remarkable growth over the last few years, both technologically and socially. The demand for real-time information has increased at exponential rates and has put existing information systems to the test. For this paper I decided to look at two new software projects that have emerged over the last few years: Cassandra and Hamachi. Cassandra is a distributed database that evolved from the needs of websites such as Twitter and Facebook, whose need for frequent and short updates was too taxing on standard RDBMSs. Hamachi, which is in part a commercial project now, started as an open-source project aimed at creating zero-config VPNs. The project is now part of LogMeIn but is still free to use for non-commercial purposes.

In normal implementation circumstances you would not find these two projects paired together, but the concept of having a distributed database over a reasonably secure connection was one I thought was worth exploring. Over the course of this paper I'll discuss both projects in a reasonable amount of detail before detailing my implementation experiment and experience.
