Devops tools fools and other smart things 

-Craftsman vs artist...

-It’s not about the tools it’s about the craftsmanship

-Tools as objects to think with

-Create places and spaces to create boundary objects

-Boundary objects give way to technical debt...

-Craftsman swaps (Week) Craftsman journey (week)... 

-Automation free up time to do more design... 


Evolving Continuous Deliver - Chris Read (GotoCon 2011) 

What we were told... (the ROE)

-Single Source Repository

-Automate Build and Testing

-Publish Latest Distributable

-Every Commit Builds

-Test in Production Like Environment

-Keep Builds Fast

-Use Information Radiators

-Automate Deployment

-Build Binary Once

-Promote Binary Through Stages

Initial State

-Releasing daily from developer

-workstations to production

-No Continuous Integration!

-Using Fig for dependency management

Stage 1 

-Standardize and Re-factor the build scripts

- Add Continuous Integration server

-Set up an Information Radiator

Later Stages....

-Sideline the Continuous Integration loop

-Bake the Continuous Integration safeties

into the deployment scripts

-Automate server builds

-Start to scale services out

-Fracture services out into stacks

-Stage the binaries

-Fast rollbacks

-1 Week to 30 minutes... 

-Requires architectural vision & discipline

-Short code half life & unix philosophy

-Minimize risk by co-locating customers

-Prodigious monitoring


Information radiator

An Information radiator is a display posted in a place where people can see it as they work or walk by. It shows readers information they care about without having to ask anyone a question. This means more communication with fewer interruptions.


Launch EC2 Spot Instances in a Virtual Private Cloud 

We've combined two popular AWS features, Amazon EC2 Spot Instances and the Amazon Virtual Private Cloud (Amazon VPC). You can now create a private, isolated section of the AWS cloud and make requests for Spot Instances to be launched within it.

Launching Spot Instances into Amazon VPC requires special capacity behind the scenes, which means that the Spot Price for Spot Instances in an Amazon VPC will float independently from those launched outside of Amazon VPC.


IBM to Acquire System Software Company Platform Computing to Extend Reach of Technical Computing 

Clusters, Grids and Clouds... 

IBM is a weird bird.. They buy overpriced companies just before they are about to go obsolete.  Cognos... Big Data?  Platform Computing... Cycle Computing.. Openstack.. 

Either they are stupid or they run the numbers and release there is money to make in the interim.. 

IBM's recent acquisitions (last 3 yrs) seem to be untimely unlike their prior 10 years...

Untethered, CFEngine hitches a lift on Android

The latest chapter of this story is the touching of two branches of this freedom: the internet information ecology and mobile communications. We are talking, of course, about smartphones and their heavier brethren `pads'. What about configuration management of these devices?

-encryption of memory,

-pin code or password protection,

-software updates, 

-application version control, are pressing.

Open Source android does not allow the notion of a privileged monitor on which most management frameworks are built.

 CFEngine has an andriod prototype..

Multi-Platform Messaging with RabbitMQ

Rob Harrop 

5 different Languages and two different protocols...  

Java2days 2009 - Java Concurrency in 5 Languages ( Scala, Java, Erlang, Clojure, Groovy).

Rob Harrop demoes how to use RabbitMQ from a variety of languages (Java, Python, Ruby and Erlang) and different environments using AMQP and STOMP to achieve for multi-platform communication.

4 Languages... 

Java, Python, Ruby, Javascript, Erlang, and Telnet....

RabbitMQ is naitivly multiprotocal . stomp, amqp. .... 

Great overview of RabbitMQ... 

Most important thing in RabbotMQ is it is not JMS.   Forget what you know about JMS and re-discover...

Ubuntu and the Cloud...

Ubuntu Orchestra

JUJU using LXC on a Laptop .. can run it in virtulization.. openstack or EC2.... 

In the front of the stage, we have a portable rack of servers (a 40-core Intel Emerald Ridge, a 24-core HP Proliant, a 16-core Dell Precision, with a System76 local Ubuntu mirror, and Cisco networking hardware).  We've used Ubuntu Orchestra to remotely install the systems, and we've deployed OpenStack to the rack.  Once OpenStack is running, Clint has a series of Hadoop jobs that he spins up and runs against dozens of instances on the local Nova compute node.  And for the real whiz-bang, Clint uses gource for dynamic visualization of the Hadoop cluster, the various nodes, and their relationships.  It is absolutely stunning to behold!

Open Stack Summit Summary...

Matt Ray... Bell of the ball.... I worked my ass off to hire him at Opscode... 

Ironic story... 

User adoption is really taking off, and we’ll be hearing from MercardoLibre, CERN, Sony Computer Entertainment America, Fidelity, Disney, and NeCTAR Summit...

Rackspace’s intention to form an OpenStack Foundation in 2012

-organizations backing OpenStack is now well over 110, including industry giants such as Cisco, HP, and Dell.

-Clouscaling, Piston and Nebula

-Techstars recently announced an incubator program for Cloud start ups

-User adoption is really taking off, and we’ll be hearing from MercardoLibre, CERN, Sony Computer Entertainment America, Fidelity, Disney, and NeCTAR

-HP using Openstack huge contributor... 

-They also plan on posting their own Chef cookbooks and apparently they have their own crowbar like implementation. 

-Dell w/Crowbar was giving demos... 

Complete list for blueprints...

Git support for gt/jenkins....

Puppet vs. Chef, Fight!

If you aren't yet using Puppet or Chef for managing your *nix infrastructure, you should seriously consider it.

The Criteria

-Community Strength


-Corporate Adoption

-Technical Merits

-Hands-on Experience

Community Size

Number of people on IRC on Sunday Oct 9th, 2011 10 AM GMT

chef:      1299 repositories

 Pro Puppet, by Puppet Labs engineer James Turnbull, is an awesome introduction to Puppet. I found it immensely helpful. There is a 50-page O'Reilly publication on Chef, Test-Driven Infrastructure with Chef, but it cannot match the breadth of Pro Puppet...

New - Amazon S3 Server Side Encryption for Data at Rest

Amazon S3 Server Side Encryption handles all encryption, decryption, and key management in a totally transparent fashion. When you PUT an object and request encryption (in an HTTP header supplied as part of the PUT), we generate a unique key, encrypt your data with the key, and then encrypt the key with a master key. For added protection, keys are stored in hosts that are separate and distinct from those used to store your data.

How Ruby is beating Python in the battle for the Soul of System Administration

- In many ways it is the love child of perl and smalltalk.

  • Ruby's greatest strength is its amazing flexibility.
  • Python intentionally has minimal magic. It's greatest strengths are the best practices it enforces across its community.


-For CM, you missed bcfg2 which is written in Python.
