Adopt Late Binding Secrets Injection

Site reliability engineers (SREs) can leverage the use of feature flags to enhance their work. Although SREs may not be responsible for creating feature flags, they should collaborate with developers to ensure that the applications they manage include feature flags.

Feature flags offer granular control to enable/disable specific features, and from an SRE's viewpoint, the ability to turn off a feature for troubleshooting without impacting the entire system is highly beneficial.

Converging configuration complexity into a single location simplifies configuration consumption (via dynamic injection). Config sprawl occurs when the complexity is pushed out to the nodes. 

Systems become hard to manage when each configuration consumer needs to know all the logic. 

Dynamic config injection using a late binding design pattern allows a system to defer the resolution of a configuration secret or parameter until runtime.

This pattern is particularly useful when injecting secrets into a continuous deployment process.
