Ciao a tutti,
un po' perché ha a che fare con Twisted, un po' perché se ne parlava
venerdì al corso del Diaolin....
http://pythondirector.sourceforge.net/
Advantages of pythondirector:
It's approximately US$11,303.42 cheaper than a cisco Local Director 417G.
Features:
- async i/o based, so much less overhead than fork/thread based
balancers. Can use either twisted or python's standard asyncore
library (twisted is recommended, and asyncore support will be
removed in a future version).
- Multiple scheduling algorithms (random, round robin, leastconns,
leastconns+roundrobin)
- If a server fails to answer, it's removed from the pool - the client
that failed to connect gets transparently failed over to a new host.
- xml based configuration file (see a sample)
- seperate management thread that periodically re-adds failed hosts if
they've come back up.
- optional builtin webserver for admin (sample of the running screen)
- webserver has methods suitable for both interactive and automated
systems
