With Clouds, Come a Chance of Rain

One of the interesting paradigms in the technology field now days is “cloud”. I think that I have seen it bandied about more then “web 2.0” a few years ago. It’s hit required buzz word compliance status in market-speak. I believe that is it over used, misunderstood and used to mislead. Let’s cut through the hyperbole and see what is really going on.

IBM claims method of homomorphic encryption

I just ran across several articles (Forbes, eWeek and The Ashdown Group) about IBM’s announcement of a mathematical method for homomorphic encryption.

When we can implement this, the implications are huge. You will be able to process large amounts of encrypted data to find broad trends, with out knowing the contents of the encrypted files.

Charles Lickel, vice-president of IBM Software Research, said: “Fully homomorphic encryption is a bit like enabling a layperson to perform flawless neurosurgery while blindfolded, without later remembering the episode.”

Filesystem scaling in high traffic web applications

One of the more interesting problems that high traffic, high load web applications face is how to scale the filesystem. As load increases, vertical scaling (bigger servers) simply does not work. You have to add more application servers, and more layers to effectively serve the needs of the users. One of the issues that many such applications have to overcome is how to serve assets (pictures, podcasts, video) to all of the edge servers that a user might access the application from, and allow users to upload user generated content.
