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...

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?

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!

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.

Hack Day in China...

Minimalist pipeline.. CI loop, CD model... 

Customer was Centos based.... 

SVN,Jenkins, Rundeck, JBoss and Mysql... (5 Servers).  

Due to cultural differences....

Make a change to the code and see the CI loop, delivery loop take place.  

The do a Roll back....

Talk about Rundeck and the mechanics - Jenkins Rundeck Plugin.  Drives the rundeck job automatically.  Also Rundeck pulls the latest, last and history of builds.  

Normally we would use Chef or Puppet on the back end of Rundeck... 

Point about manual vs automated process


A Contentious Question by Chris Hoff (@beaker)

Contentios question by @beaker.. no,  Actually if you guys don’t follow @beaker you should.  He is our #devops mirror for networking and security (imho).  He tried to keep us honest...

“Given the recent influx of virtual networking solutions, many of which are OpenFlow-based, what possible in-roads and value can they hope to offer in heavily virtualized enterprise environments wherein the virtual networking is owned and controlled by VMware?”

Specifically, if the only third-party VMware virtual switch to date is Cisco’s and access to this platform is limited (if at all available) to startup players, how on Earth do BigSwitch, Nicira, vCider, etc. plan to insert themselves into an already contentious environment effectively doing mindshare and relevance battle with the likes of mainline infrastructure networking giants and VMware?

If you’re answer is “OpenFlow and OpenStack will enable this access,...

Not meaning to piss anyone off, but many of these startups’ business plans are shrouded in the mystical vail of “wait and see.”

Gartner Cites Application Release Automation Tools as Key to DevOps

So many things wrong with this...   (ARA) Nolio 

 As an emerging movement, DevOps may have improved communication and collaboration between development and IT operations teams but it still hasn’t absolutely mastered its ultimate goal of unifying their work. 

 In his report, Ronni J. Colville argues that DevOps can be greatly enhanced by the use of application release automation (ARA) tools and specifically cites Nolio as one such solution.

Can tools help “Cuture”  this question was asked at Puppetconf w/Luke... 

Visibility also requires the establishment of a model of the application and its configuration for each environment. ARA tools can provide a mechanism to create application models for each environment, with externalized configuration settings that typically vary by environment.


Selenium and Nagios

I've implemented a Nagios check for Selenium test cases. With this check it is possible to put your recorded test cases from your Selenium IDE into Nagios to use them for monitoring.

Test-->Selenium IDE-->Export-->check_selenium (nagios plugin)-->Selenium Remote Control


DevOps in Milliseconds

AppNexus engineers have it good. 

They don’t lie awake at night wondering if we can handle the next increase of impressions. 

They don’t worry that our systems are down and we don’t know it. 

They don’t develop in a bubble, toss their code over the wall to a mysterious group of people, and wash their hands clean.

Monitoring: Nagios - 1200 services

Metrics: Graphite - 1 million datapoints every minute.

Nagios plugin that queries Graphite and alerts if values of certain metrics go above or below specified thresholds.

Deployment: Puppet and Maestro

Puppet backed by a MySQL database and fronted by an in-house application we call Maestro.

At AppNexus there is no wall between engineers and operations, and automation is crucial to scaling our infrasctructure. 

Engineers control their own destiny, and we give them the tools to dive deep into production problems and give them tools to dive deep into production problems, make fixes, and improve their products as quickly as they can code.


CI vs Zombies

Runaway builds.

--A runaway build occurs when not all processes created by the build exit cleanly. 

--Zombies – may hang the build, or simply stay around in the background waiting to wreak havoc. 

--They interfere with test isolation. If processes can hang around from an earlier build (or earlier test within the same build) they may affect unrelated tests.

--difficult-to-diagnose failures.

-- eventually leading to exhaustion.

--Manual intervention is required to kill them and clean up.

Mean time to pretty chart- DevOps meets data porn

Alex Benik is a principal at Battery Ventures. Battery Ventures is an investor in DataDog and Tracelytics. 

The current mantra in Web operations is to track, record and monitor everything. Data is valuable and storage is cheap.

Favorite Velocity  John Rauser at Amazon and Kellan Elliot-McCrea from Etsy.

Mean Time to Pretty Chart (MTPC). For full buzzword compliance, let’s say that WebOps + BigData + Information/Graphic Design = MTPC.

MTPC attempts to quantify the amount of time required to determine the root cause of an operational issue and depict it in an eye-catching way. The MTPC metric is challenging because it encompasses a number of challenges spanning large volumes of data acquisition, storage, correlation and design/representation.

A highly incomplete list of relevant commercial and open source tools would include Ganglia, Nagios, Cati, Graphite, Munin, Splunk, New Relic, Tracelytics (see disclosure), DataDog (see disclosure), and AppDynamics.

Enter the Data Scientist. While correlation doesn’t imply causation, with large enough sample sizes the old adage “where there is smoke there is usually fire” often applies. When you can visualize that smoke in a pretty chart, it’s easier to pinpoint the fire.

Puppet Enterprise 2.0

A lot of new integration with Mcollective and the GUI...

New GUI, right out-of-the-box PE 2.0 automatically discovers all resources – packages, hosts, groups, and users.  Uses Mcollective to discover. 

Visually Clone Resources To Scale Quickly, Efficiently, and Reliably(From the GUI)

With PE 2.0’s new  compliance capability, you now can visually monitor for any unauthorized changes against your desired-state baseline. Can run compliance reports once a day and watch for changing trends...  Give auditors GUI control to see what they need to see...

PE 2.0’s new provisioning capability allows you to quickly and easily create new instances of VMware and Amazon EC2.  KInd of like “Knife” with the added bare metal sauce... 


“Operating at Scale”

Pedro Canahuati

SRE Manager... 

Dealing with issues at “SCALE” and I mean scale....

Switched from XEN to LXC to to overhead at scale...

Been using cFengine for years... About to change to Chef or Puppet.. Looking at both. 

All the #devops thing are going on at FB  CD, Agile in operations, collect and store everything.  Like Google, they had to build a lot of their own stuff.  

They build there own TSDB kind of like Opentsdb.  They have built there own monitoring framework, looking framework (they use Scribe).

ODS tool the abstracts and visualizes all events (very cool) 

I was able to talk to Pedro at the speakers dinner and the following day.  I am a junkie and groupie for guys like this and stuff like .. we talked about CEP and monitoring.  Also about Chef and Puppet.
