There's been a lot of work on the migration to Kubernetes (k8s) under the MozMEAO SRE team.  Dependencies in Bugzilla are out of date. Some migration strategies have changed, and some actions will be deferred to post-migration. I'll update over the next week.

The AWS migration project is tracked at:

bug 1110799: Add newrelic config file

This is the default config, with some settings expected from the
environment:

* NEW_RELIC_LICENSE_KEY for license_key
* NEW_RELIC_APP_NAME for app_name
* NEW_RELIC_MONITOR_MODE for monitor_mode (1 to talk to NR)

The changes from the default:

* log_file = stderr
* high_security = true (Mozilla standard)
* browser_monitoring.enabled = false (added, Mozilla standard)
* browser_monitoring.auto_instrument = false (Mozilla standard)

bug 1110799: Expand raven/sentry configuration

* Send the revision hash, for release tracking
* Set a syncronous transport, which may be more compatible with meinheld
* Set the repos name, which may make tracebacks more useful
* Ignore DisallowedHost exceptions, which happen in AWS

The migration went smoothly, with one issue that was handled during the maintenance window [1].  We've been in AWS for 48 hours, and have added some resources to more smoothly handle some traffic spikes. There are many follow-on actions [2], but it looks like it will work.

We'd like to keep SCL3 up as an emergency backup for awhile, but it looks like we're in AWS for good.

Thanks to everyone who worked on the first phase of this project. Etherpad is having trouble staying available, so I made a copy of the original plan [3]. It was a lot more ambitious, both in schedule (Q3 2015) and in scope. Hopefully we can return to implement some of the ideas.
