“Release Engineering from the Beginning”

slide-13
SLIDE 13

Release Engineering from the Beginning

  • Cheaper to put good practices in place early
  • Releng, developers, testers and SRES work together
  • Releng must understand the intent of how the code should

be built and deployed (and then help define the processes)

  • No “Build and Pray”

  • Hermetic build process
slide-23
SLIDE 23

Hermetic (Dictionary.com)

  • 1. made airtight by fusion or sealing.
  • 2. not affected by outward influence or power;

isolated.

  • 3. of, pertaining to, or characteristic of occult

science, especially alchemy.
