The Future of Feature Flags: Managing Dynamic Applications (opens in new tab)

Traditionally, software teams have used feature flags/toggles to control simple rollouts and enable kill switches. Boolean values were used for “on” or “off”, “true” or “false”. With the introduction of multivariate flags, developers have been experimenting with serving rich values via these flags: strings, numbers, JSON objects, and JSON arrays. This has opened up a whole new world of dynamic application management.
