After less than a week OSP has reached another milestone in it’s development! Version 0.2 was just released with a few big fixes, performance improvments and added functionality. Also the documentation has been improved and made consistant with the code.

The most important bug fix was a performance issue that caused a slowdown over time, this has been fixed and along with it, the performance and scalability has increased! The biggest feature added was support for UDP (and soon SCTP, and SSL) which can be set without changing the code! Imagine writing a server and deploying it using TCP, UDP, SSL and SCTP, just by changing one line in the XML servlet.

Setup should be simple too, just download from Google Code, extract, make and then compile your servlet. Now on the first node, run ./start-osp.sh and then you can telnet to port 9876 and administer your cluster.

Just writing a little status update for my Open Server Platform (OSP) project that I’ve been working on:

Progress:

• Rewrote much of OSP to take in a XML servlet (meta-data and code) and act as a socket broker for that servlet.
• Wrote a  number of  servlet libraries to make programming easier and safer.
• Added a global shared state that can be spread redundantly across multiple nodes (using Mnesia)
• Added the ability for applications to be atomic, either they complete and update the shared state, or they crash and don’t influence the shared state at all.

Todo:

• Move the OSP broker under an OTP supervisor for auto-restart.
• Make OSP more configurable and automatic
• Make a nice administration and status system
• Devise and implement a load balancing and fail-over system
• Test and tweak as needed
• Write more servlet libraries

Also, I have been approached by a CS senior from the west coast who has offered to help work on ERLFS! I’d love more help if you know/want to learn Erlang, and help develop a very powerful and useful product.
