Episode notes
Diverse Early Career
- David Flanagan's early career involved diverse technologies like Perl, C#, PHP, and C, driven by a passion for reverse-engineering and experimentation.
- He learned by doing, modifying kernel code for custom boot images and building e-POS systems.
Team Rock Scaling Challenges
- At Team Rock, Flanagan faced scaling challenges due to unpredictable traffic spikes from news events like album releases or celebrity deaths.
- Initial scaling attempts involved golden images and VMs, but these proved insufficient.
Early Docker Adoption

- This allowed them to handle unprecedented traffic, though AWS's ELB provisioning based on previous scale remained a bottleneck.
