About Bitfield Consulting

John Arundel, principal consultant, author, and devops expert, has been writing software for 35 years, managing Unix systems for two decades, and hacking on infrastructure from nuclear power stations to Netflix since he was knee-high to a login prompt. He has been using Puppet in commercial web operations for over 10 years and has deployed Puppet solutions for dozens of companies from Singapore to Seattle, and at fairly large scales (many thousands of servers in a single site). He is also the author of The Puppet Cookbook and The Puppet Beginner’s Guide, which have sold more than 15,000 copies, and regularly provides coaching and training on Puppet from beginner to enterprise level.

John also regularly regales his 100,000+ Twitter followers with deep thoughts about computing, configuration management, and software development at @bitfield. Even though no-one can agree what ‘devops’ means, it seems to be a partial description of what he does.

He works closely with selected clients worldwide, consulting, coaching, and training on:

  • Building devops and operations teams
  • Building a friendly, collegial, supportive, diverse, and effective team culture
  • Building scalable, reliable, and high-performance infrastructure
  • Automating systems with Puppet
  • Development workflow with Git
  • Deploying apps and services with Docker
  • Virtualization, cloud infrastructure, and containerization
