Archaius

Archaius is a software library developed by Netflix that helps manage and adjust application settings dynamically. It allows programs to change their configuration values—like feature flags or connection details—without needing to restart or redeploy. This flexibility enables applications to adapt quickly to different environments, such as testing, production, or emergency updates, ensuring stability and responsiveness. Essentially, Archaius acts as a centralized, real-time configuration manager, simplifying how developers control and update application behaviors efficiently and safely.
