Kspice is a useful technology for BI and Hadoop
Clip Man
Having infrastructure that is completely redundant and easy to bring down for Linux kernel upgrades is a wonderful thing, but it is pretty hard and frequently you end up with systems that still require downtime maintenance windows for rebooting.
Here are a few examples I can offer:
  • Pentaho BI server
  • ETL processing servers
  • Data warehouse database servers
  • Vertica cluster nodes
  • Hadoop NameNode

What Ksplice does is pretty cool.  They take your currently installed Linux kernel and apply a series of in-memory binary patches to it without requiring a reboot to keep you up to date with the latest security patches. You can be patched and secure within hours of a critical update.
