If you have time today to pop into #fedora-server, I'd love to
brain based on your sysadmin experience to help flesh some of these out
better! I'm mizmo.
Below is my summary of the conversation; let me know if I missed
anything or misrepresented anything!
* Works for a large company
* Works on a team of 6 sys admins, 2 in Peru, 4 in Chicago
* Manages approximately 1000 servers
* Half and half physical/virtual (KVM and Xen Cloud)
* All Java
* Each environment is cloned, the differences are in the versions of
mod_jk and/or JDK
* Load-balancing configuration
* Changes managed via scripts (shell vs python or perl depends on the
complexity) - company policy requires these are written and maintained
* Automate all the things!
* Better understand the status of all systems, including installed
software and utilization of system resources.
* When modifying a system, define a recipe that describes the changes to
make, then later do a diff on the system to see the correct functionality
* I like the idea of being able to customize on the needs one can have
* Production pushes where the JDK crashes.
* Production pushes where the VM has to be taken down and have its
capacity raised before the new version of the application can be started.
