Hello everyone!

This is mostly notes to myself after watching this talk (after DevOps Weekly told me about it in one of their emails).  I found the following bits of info pretty interesting and wanted to begin to apply this to some of the things I've been working on.

16:41 -> Created an puppet module to apply IS benchmarking

20:56 -> rsyslog => graylog2 to roll all of their logs into one place

23:35 -> Network traffic logging... AWS Security Groups and Network ACL's don't log anything, Needed to log all traffic going in and out on any level of the VPC
      -> Puppet + IPTables +Rsyslog +Graylog2
28:26 -> Facter fact for determining zone with ugly regex... tag zone by IP address... same for 'tier'

31:00 -> greylog2 was really good, millions of events in, really fast.

32:40 -> Performance of large catalogs was bad with puppet 2.7, Hiera-Gpg is cumbersome
  recursion to remove checksums on big directories
   file { "/etc/somedir":
     recurse => true,
     ignore => ['work', 'temp', 'log'],
     checksum -> none,
    (you don't want checksums on tomcat work directories)
    Hiera-GBG is cumbersome, they switched to a mysql hiera backend

34:45 -> cloudformation json is ugly...
         CFNDSL = ruby DSL for CloudFormation templates
         use for cloudformation template generatoin

35:22 -> unified state and lifecycle management -> Doesnot exist...
37:13 -> One single truth  source for
         1. audit trail/logging
         2. Instance status
         3. App status
         4. CRUD actions on the whole infrastructure

39:40 -> puppetlabs aquired cloudsmith... is that heading toward some unified state and lifecycle management?

40:50 -> CIS, tmp should be on a different disk, did some trickery to shuffle it around?

42:00 -> Switched from CIS application and snapshot of AMI to applying the CIS benchmark once a day and using all default AMI
 -> That prevented people from taking a hardened base image and fudging something setup by CIS .  Once every halfhour got to cumbersome
