About the Book

Build Quality In

Build Quality In is a book of Continuous Delivery and DevOps experience reports from the wild.

The interdependent disciplines of Continuous Delivery and DevOps are of immense value to an organisation, but they are hard. We have seen Continuous Delivery and DevOps work in the wild, as have other practitioners. We want to help people on their own Continuous Delivery and DevOps journey, by sharing the experiences of those who have done it – what worked, what didn’t, and the highs and lows of trying to build quality into an organisation.

Contributors

We have an incredible group of Continuous Delivery and DevOps practitioners, who have freely shared their own first-hand experiences in this area.

Thanks to all our contributors!

Steve Smith and Matthew Skelton

Forewords

The Continuous Delivery foreword is written by Dave Farley. Dave Farley is co-author of the Jolt award winning book Continuous Delivery. He has been having fun with computers for over 30 years. Over that period he has worked on most types of software. He has a wide range of experience leading the development of complex software in teams, large and small. Dave was an early adopter of agile development techniques, employing iterative development, continuous integration and significant levels of automated testing on commercial projects from the early 1990s. More recently Dave has worked in the field of low latency computing developing high performance software for the finance industry. Dave currently works for KCG Ltd.

The DevOps foreword is written by Patrick Debois. Patrick Debois is a developer, manager, sysadmin, and tester. He first presented concepts on Agile Infrastructure at Agile 2008 in Toronto, and in 2009 he organized the first DevOpsDays . Since then he has been promoting the notion of ‘devops’ to exchange ideas between these groups and show how they can help each other to achieve better results in business.

An Interview with Matthew Skelton

James Betteley

Doing the DevOps thing

Many years ago, someone decided to put me in charge of doing builds and releases of software. I can't remember why, I think everyone else was out at lunch. I inherited a system of batch files, shell scripts and all sorts of weird and wonderful things which, to this very day, I still don't understand. Since then I've made it my job to debunk complicated software systems, automate as much as possible and just try to make things more sensible. My main driver is bringing real business value through great Development & Operations processes, whether that be by using tools or implementing a new process or culture. Check out my blog at http://devopsnet.com/

John Clapham

Simon Hildrew

Simon led the Guardian's digital operations team for two years before changing role and becoming a developer (albeit with an operations focus). Since then he has tackled pain points encountered by operations, including writing tooling that enables deployments to be carried out more reliably and more frequently across a diverse range of legacy and new product stacks. His aim is to create solutions that developers don't need to be coerced into adopting, but they want to use because they eliminate hassle and manual work from their jobs.

Alex Wilson

Alex Wilson has been a software developer at Unruly for approaching two years, during which time he has had the opportunity to experience and solve scaling issues with their software development methodologies. He takes particular delight in the application of both Continuous Delivery and Xtreme Programming practices to the "DevOps" process, made easier by Unruly's stance of emphasising the value of generalists over specialists.

Chris O'Dell

Chris has been developing software with Microsoft technologies for nearly fourteen years. She currently works at Monzo helping to build the future of banking.

She has led teams delivering highly available Web APIs, distributed systems and cloud based services. She has also led teams developing internal build and deployment tooling using the unconventional mix of .Net codebases onto AWS infrastructure.

Chris promotes practices we know as Continuous Delivery, including TDD, version control, and Continuous Integration.

Niek Bartholomeus

Niek Bartholomeus is a DevOps and Continuous Delivery evangelist who has implemented a Continuous Delivery pipeline during his most recent mission at ReQtest, a small agile company. Before that he was a technical architect at a large financial institution where he was responsible for bringing together the dev and ops teams, on a cultural as well as a tooling level. He currently works as a DevOps consultant for BMC. He has a background as a software architect and developer and is fascinated by finding the big picture out of the smaller pieces.

Sriram Narayanan

Continuous Delivery Consultant, Thoughtworks

I presently consult to customers on their Continuous Delivery and Agile Transformation needs. I bring to the table my knowledge regarding Infrastructure Automation, Agile Development practices and computer software technology, Software and Hardware Deployment, Enterprise Infrastructure, reducing time to market, and improving quality. I'm also working on Belenix (www.belenix.org), an Illumos based distro. Belenix used to be the foundation of the now-defunct OpenSolaris distro. My current interests are OpenStack, Release Engineering for the Belenix/Illumos platform, and DTrace

Phil Wills

Phil is senior software architect at the Guardian. He has worked on just about every part of the Guardian’s site and the tools which support it; building features, optimising performance and increasing resilience.

Anna Shipman

Anna Shipman is a senior developer at the Government Digital Service. She works on the infrastructure team that supports the GOV.UK website, doing development and web operations. Currently she is working on open source tooling to provision VMware vCloud Director environments: https://github.com/alphagov/vcloud-tools. She works mainly in Ruby and Puppet at the moment, though her past includes Python, Perl, Java and the JEE stack. She blogs at www.annashipman.co.uk, tweets at @annashipman and is always up for a game of pool.

Rachel Laycock

Rachel Laycock works for ThoughtWorks as a Market Technical Principal with over 10 years of experience in systems development. She has worked on a wide range of technologies and the integration of many disparate systems. Since working at ThoughtWorks, Rachel has coached teams on Agile and Continuous Delivery technical practices and has played the role of coach, trainer, technical lead, architect, and developer. She is now a member of the Technical Advisory Board to the CTO, which regularly produces the ThoughtWorks Technology Radar. Rachel is fascinated by problem solving and has discovered that people problems are often more difficult to solve than software ones.

Code Club

https://www.codeclub.org.uk

A nationwide network of volunteer-led after school coding clubs for children aged 9-11.

We create projects for our volunteers to teach at after school coding clubs or at non-school venues such as libraries. The projects we make teach children how to program by showing them how to make computer games, animations and websites. Our volunteers go to their local club for an hour a week and teach one project a week. Each term the students will progress and learn more whilst at the same time using their imaginations and making creative projects. Terms 1 & 2 use Scratch to teach the basics of programming. Term 3 teaches the basics of web development using HTML and CSS. Term 4 teaches Python and so on. We’d like to put a Code Club in every single primary school in the country. There are over 21,000 primary schools in the UK, it’s a big task but we think we can do it!
