Juniper Adds Puppet support
This is super-cool.

'Network engineering no longer should be mundane tasks like conf, set interfaces fe-0/0/0 unit o family inet address 10.1.1.1/24. How does mindless CLI work translate to efficiently spent time ? What if you need to change 300 devices? What if you are writing it by hand? An error-prone waste of time. Juniper today announced Puppet support for their 12.2R3,5 JUNOS code. This is compatible with EX4200, EX4550, and QFX3500 switches. These are top end switches, but this start is directly aimed at their DC and enterprise devices. Initially, the manifest interactions offered are interface, layer 2 interface, vlan, port aggregation groups, and device names.'

Based on what I saw in the Network Automation team in Amazon, this is an amazing leap forward; it'd instantly render obsolete a bunch of horrific SSH-CLI automation cruft.

serverspec - unit tests for servers
With serverspec, you can write RSpec tests for checking your servers are provisioned correctly. Serverspec tests your servers' actual state through SSH access, so you don't need to install any agent softwares on your servers and can use any provisioning tools, Puppet, Chef, CFEngine and so on.

Building with Legos
Netflix tech blog on how they deploy their services. Notably, they avoid the Puppet/Chef approach, citing these reasons: 'One is that it eliminates a number of dependencies in the production environment: a master control server, package repository and client scripts on the servers, network permissions to talk to all of these. Another is that it guarantees that what we test in the test environment is the EXACT same thing that is deployed in production; there is very little chance of configuration or other creep/bit rot. Finally, it means that there is no way for people to change or install things in the production environment (this may seem like a really harsh restriction, but if you can build a new AMI fast enough it doesn't really make a difference).'
