DevOps Enterprise Summit – London 2016

I once again had the privilege of attending the DevOps Enterprise Summit.  This time it was in the U.K. at the Hilton Metropole.  I was impressed with the representation and talks from companies and organization across the UK and the rest of Europe:  SAP, ITV, Hiscox, ING, Barclays, HMRC, Zurich, and many more.

Themes that I picked up from these DevOps leaders:

  • People – Its all about People – empathy, org change, transformation
  • Speed – Continuous Integration and Delivery
  • Quality – Investment in DevOps practices often results in higher quality output
  • Agility – Microservices and Flexible Infrastructure
  • Security – Everyone’s responsibility
  • Business – Focus on Product vs. Project with integration with business in transformation (BizDevOps?)

I was honored to speak again and talk about our DevOps journey at Disney.

How to Effectively Communicate to Leaders

As an leader who loves working with people, I often have the pleasure of hearing from individuals at all levels across the organization.  However, I am often amazed at how many people fail to communicate effectively with their leaders and others. They are terrible at scheduling meetings, pitching their idea or even asking for help. That got me to thinking, what advice would I give to anyone who needs to communicate with me or other leaders? I came up a list of 7 imperatives that I have learned from those who are the most successful.

1) Be contextual – I often have meeting invites or receive emails or presentations that provide little or no context. The senders may have mentioned it in a prior exchange and are usually saturated in the subject themselves, but most leaders are constantly task switching and juggling multiple ideas, projects, discussions, etc., and can struggle to make connections back to the senders requests. While we all want to be superhuman and always “know what you are talking bout”, the truth is that we have a finite capacity to retain more than a handful of contexts. Provide “helps” to onboard the leader and the rest of the audience quickly. That will help you succeed in getting the point across and if needed, a decision. I love seeing context in the meeting invite or email, or in the case of ad hoc meetings, and introductory summary for why he or she should listen to you.

2) Be brief – As with most leaders, I get several hundred emails, calls, texts and IMs per day. I must skim to survive. You should fashion your communications so that important ideas are highlighted. For written communication, make use of white space to help the eye quickly skim and do what you can to avoid unnecessary language. Can I suggest that executives aren’t the only ones who appreciate this and anyone who discovers this art of concise and effective communication will succeed in their career?

3) Be real – Leaders see through bogus accomplishments and self promotion. I’m most impressed with people who are respectful but direct, confident but humble, and candid but optimistic. They spend more time acknowledging others and the achievements of their team rather than their own.

4) Be kind – Good leaders have little tolerance for other leaders or managers who berate, belittle, or otherwise deal harshly with their team or others. Don’t expect to find a gracious audience with your own leader if you can’t deal respectfully, courteously and graciously with your own staff and partners. Treat others as you want to be treated.

5) Be honest – I’ve seen individuals and teams manipulate messages and presentations to get an executive decision or modify perception without providing all the details or slightly modifying the story. If you know something that could materially impact the decision process, why are you hiding it? Blocking signals to manipulate circumstances for your own benefit will backfire on you personally and in some cases have a significant impact on the company, brand, employees or customers. Be honest.

6) Be optimistic – Good leaders are not looking for everyone to be Pollyanna and will prefer a difficult truth to a comforting lie, but rarely are things without hope or some positive element. Bring a bias toward positive solutions, look for the opportunity in the disappointment, the lesson in a setback or wisdom in a failure. Business is about taking risks and moving forward from mistakes. Surround yourself with others who believe we can make a difference and impact the world for the better. Be an optimist.

7) Be proactive – Don’t just tell your leader what someone else needs to do, take action yourself. It’s great to have a plan to make something better and to bring that to the attention of your leader, but be prepared to be part of the solution!  Leaders are always on the lookout for a great idea with muscle. What are you doing to turn your great idea into reality? Get started.

This list is in no way comprehensive, but hopefully it will help you as it has helped me.

The Art of Business Value

art-of-biz-valueA review of The Art of Business Value by Mark Schwartz

Business value, the north star of Agile, Lean and DevOps champions, is often more difficult to determine than one would imagine. This book takes the reader on a journey to discover that value while along the way, creating helpful mental models, challenging preconceived notions and proposing some creative ways to transform an organization.

The author does a great treatment of ROI (Return on Investment – does anyone ever really measure that?), NPV (Net Present Value), MVA (Market Value Added) and SVA (Shareholder Value Added). I especially enjoyed the humorous practical example that revealed a surprising truth that acquiring an MBA can easily have a negative NPV (in other words, a bad investment!) So save your money and pay attention to the author’s “four-paragraph MBA” (p. 20) that unpacks the main two principles learned in an MBA: 1) There is time value of money and 2) A business venture needs a sustainable competitive advantage.

Legacy IT architecture and bureaucracy are often considered negatives and obstacles to progressive competitive relevance but the author brings a refreshing perspective on the “value” of that complex hairball of legacy and rules and the right way to polish and transform them.

On Agile…

“The purpose of an Agile team is to self-organize and meet the underlying business need in the best way possible, often by cutting through the bureaucracy.” (p 55)

On DevOps…

“The DevOps model…looks to break down the silos that have resulted from technical specialization over the last few decades. But the DevOps spirit goes further looking to eliminate the conflicting incentives of organizational silos and the inhumane behaviors that can result from those conflicting incentives.” (p 48)

On Bureaucracy…

“Bureaucracy delivers business value. Just sometimes not enough.” (p 59)
…”developers are bureaucrats by nature. We have a tendency to solve problems by creating standard processes rather than by relying on human judgment.” (p 54)
“The pipeline is an automated bureaucracy: it applies its rules in a rigorous, unemotional way, sine ira et studio. That does not mean that the software development process is unemotional; it means that the tools are unemotional and the passion is brought to the process by the people.” (p 105)

And on Business Value…

“Business value is a hypothesis held by the organization’s leadership as to what will best accomplish the organization’s ultimate goals or desired outcomes.” (p 90)

I highly recommend this book to IT leaders, digital executives, strategic managers, and anyone seeking to make their organization more agile, effective, relevant, competitive and humane.

Docker + Mesos + Marathon in AWS EC2

I wanted to see if I could get a Docker + Mesos + Marathon platform up and running quickly in AWS EC2 using t2.micro instances.  I found this great article by Gar (@gargar454) where he has put all the components in docker containers and provides a simple  tutorial which I paste below with some minor edits:

Create a Docker Host on EC2

Create your EC2 instances (Amazon AMI t2.micro will work), set it up in your private VPC and auto-assign a public IP so you can test.  You will need to open TCP ports 5050 and 8080 in  your security group from your workstation if you want to see the Mesos and Marathon UIs.   Run these commands to set up a docker host:

sudo yum update -y
sudo yum install -y docker
sudo service docker start
# grant ec2-user ability to run docker commands without sudo
sudo usermod -a -G docker ec2-user
# you must exist to refresh user rights
exit
  1. Export out the local host’s IP
    • HOST_IP=`wget -qO- http://instance-data/latest/meta-data/local-ipv4`
  2. Start Zookeeper
    docker run -d \
    -p 2181:2181 \
    -p 2888:2888 \
    -p 3888:3888 \
    garland/zookeeper
  3. Start Mesos Master
    docker run --net="host" \
    -p 5050:5050 \
    -e "MESOS_HOSTNAME=${HOST_IP}" \
    -e "MESOS_IP=${HOST_IP}" \
    -e "MESOS_ZK=zk://${HOST_IP}:2181/mesos" \
    -e "MESOS_PORT=5050" \
    -e "MESOS_LOG_DIR=/var/log/mesos" \
    -e "MESOS_QUORUM=1" \
    -e "MESOS_REGISTRY=in_memory" \
    -e "MESOS_WORK_DIR=/var/lib/mesos" \
    -d \
    garland/mesosphere-docker-mesos-master
  4. Start Marathon
    docker run \
    -d \
    -p 8080:8080 \
    garland/mesosphere-docker-marathon --master zk://${HOST_IP}:2181/mesos --zk zk://${HOST_IP}:2181/marathon
  5. Start Mesos Slave in a container
    docker run -d \
    --name mesos_slave_1 \
    --entrypoint="mesos-slave" \
    -e "MESOS_MASTER=zk://${HOST_IP}:2181/mesos" \
    -e "MESOS_LOG_DIR=/var/log/mesos" \
    -e "MESOS_LOGGING_LEVEL=INFO" \
    garland/mesosphere-docker-mesos-master:latest
  6. Goto the Mesos & Marathon Web pages
    # You can find your EC2 instance public IP address with:
    wget -qO- http://instance-data/latest/meta-data/public-ipv4

    Mesos Web Page

  7. http://<public-ip>:5050

Marathon Web Page

http://<public-ip>:8080

Create an App (+ New App button) on the Marathon page to see the task get assigned to a Mesos slave and executed.

Marathon New App - test1

Log in to the slave container and watch the file grow:

docker exec -it mesos_slave_1 /bin/bash

tail -f /tmp/running.out

AppleTV Development – OpenSSL and libcurl

In doing development for the new AppleTV, I was unable to find a cross compiled version of OpenSSL and cURL (libcurl) to use for my project.   I found a helpful OpenSSL script (here) that addressed some the unique tvOS challenges (e.g. fork() is not available) and used that build script to construct an libcurl build script.

The following repo contains scripts to build OpenSSL and cURL (libcurl) for OS X, iOS and tvOS with Bitcode enabled for iOS, tvOS. It includes the required patching for tvOS to not use fork(). This requires Xcode7.1b or later for the tvOS SDK.

DevOps Enterprise Summit 2015

It was great to attend the DevOps Enterprise Summit again this year. The 2015 edition saw more than double the number of attendees of the 2014 conference with presentations from companies all over the world. There is definitely a feeling that DevOps is awakening across the enterprise.

I had the privilege of presenting again on Disney’s Journey,
“Disney DevOps – The Enterprise Awakens.”

Fellow DevOps Avengers from all over the world converged to swap stories, share new insight, technology and encourage each other to keep moving forward as the Force of positive change in our various industries.
