WTF is Cloud Native: Enabling Engineering Productivity at the Financial Times

The Financial Times has embraced autonomy in our development teams, and as a result we move pretty fast - over 30,000 releases in a year from a development team of around 250. Because we have a wide variety of technical architectures, processes and team structures, we need to make sure that all those autonomous teams build in security, fault detection, and cost efficiency.

This is the responsibility of the Engineering Enablement group at the FT: teams who provide tooling and services for common capabilities like DNS, content delivery, cloud provisioning, observability, etc.; manage relationships with vendors; and provide insights and oversight to all our development teams.

To do this effectively, we have adopted principles and practices that centre on making sure teams don’t need to wait for us to do things, and we have stayed constantly focused on what our customer teams need from us.

In these slides, I discuss our approach and share what you can learn from our experiences working in this area for the last three years.

  5. @sarahjwells Owned and supported It won’t disappear under people Transparent

    usage and cost insights It’s clear who is using it and how much their bill would be Can people rely on it?
  6. @sarahjwells Discoverable Engineers can find out it exists Documented Step

    by step guides, explainers, reference docs all exist Self service You can solve your problem yourself Can people use this without costly co-ordination?

  8. @sarahjwells • Automatically approve simple stuff • Send DMARC/DKIM/MX changes

    to Cyber Security team for approval • Check for common mistakes • Look for modifications that are benign and auto-approve • Use biz-ops to find a suitable team member that can peer review
  9. @sarahjwells Easy to use Documentation guides new users - an

    ‘on-ramp’ Consistent developer experience If you’ve used other capabilities, this should be recognisably similar Will people get stuck?
  10. @sarahjwells Independent yet composable You can use it on its

    own or combine it with other capabilities Automation friendly APIs, SDKs, CLIs Can people use it in ways we didn’t expect?
  11. @sarahjwells Safe to use Sensible defaults, small blast radius Secure

    and compliant Security issues are fixed for you, capabilities comply with our policies Reliable Suitable levels of availability, scalability and performance Does it guide people to do the right thing?
  12. @sarahjwells Valuable Owned and supported Transparent usage and cost insights

    Discoverable Documented Self service Easy to use Consistent developer experience Independent yet composable Automation friendly Safe to use Secure and compliant Reliable
