= Introduction =
At Release Engineering we do builds and tests of Firefox, Firefox for Android, Firefox OS and Thunderbird. We also do some other tier-2 type of jobs on the same hardware used to ship the mentioned products.
For builds, we build both on real hardware and VMs (in-house & AWS).
For unit and performance tests (aka talos), we build both on real desktop machines, VMs (EC2) and mobile development boards (tegras & pandas).
As we move everything to scl3, we can see the purpose of the machine indicated on the full hostname (try build machines VS release build machines VS test machines VS "Windows" vlan).


== Notes ==
* We only use "try" or "y" for ec2 instances since renaming is harder with in-house hosts
* We are unable to use hostnames longer than 15 characters on Windows, so any try hosts in EC2 are y-2008, not try-2008.
* Moving machines from the try vlan to the build vlan will requires hostname changes (after the first 'dot').
= Proposed naming =
== Server hostname convention ==
P-O-T-XXXX
1) P = purpose
* "b-" - for build machines
* "t-" - for test machines
* "y-" - for try machines in AWS
<br />
2) O = OS + instruction size (optional)
* xp32/w732/w864/w1064/2008/2012
** we currently use "w64" for "w2008"
* linux32/linux64
** for linux we camouflage the distro
* snow/lion/mtnlion/mavericks/yosemite
3) T = Type of hardware
<br />
For VMs:
* "ec2" for Amazon on-demand instances
* "spot" for Amazon spot instances
* "vmw" for in-house vmware
<br />
For real hardware:
* "ix" for ix machines
* "r#" - # depends on the revision of Mac mini that we use
<br />
4) XXXX = number (or XXX = number in AWS)
<br />
Fixed digits allow lexical sorting, but limit to 9999 slaves per type. This is at variance with numbering throughout the rest of Mozilla, where zero-padding is not used.
=== Examples ===
Build machine examples:
* b-2008-spot-XXX (15 chars)
* b-2008-ix-XXXX (14 chars)
* b-lion-r#-XXXX
<br />
Try machine examples:
* y-2008-spot-XXX (15 chars)
* y-linux64-spot-XXXX
* y-linux32-spot-XXXX
<br />
Test machine examples:
* t-linux32-spot-XXXX
* t-linux64-spot-XXXX
* t-linux32-ix-XXXX
* t-linux64-ix-XXXX
* t-snow-r4-XXXX
* t-yosemite-r5-XXXX
* t-xp32-ix-XXXX
* t-w732-ix-XXXX
* t-w864-ix-XXXX
* t-w1064-ix-XXXX
== Mobile hostname convention ==
T-XXXX
T = type (e.g. panda)
Examples:
* panda-XXXX
== Other infra ==
buildbot-masterXX - for buildbot masters
foopyXXX - for foopy machines

As of January, 2014 (note that machines have moved to four digits)
