Sadly I didn't attend the tech talk, but just going through the slides gave me a pretty good impression of how they went about scaling the company. Particularly near to my heart are the key principles that Mark mentions as characterizing the philosophy by which Instagram operates:
- Simplicity
- Optimize for minimal operational burden
- Instrument everything
Smart companies minimize their operational burden by using best of breed services for non core tasks such as chat, project management, customer relationship management, bug tracking, etc. With Metrics we now provide the same possibility for instrumenting all aspects of a company’s operation and we’re seeing some great examples of companies using it just in this manner, such as Travis-ci.org. If you haven't already, give us a try!
