Easily configure which feature flags are enabled for which users. Unleash has built-in default strategies like Progress Rollout that make getting started easy. Custom constraints allow targeting feature rollouts based on any attribute you can imagine like geo, customer type, or arbitrary telemetry.
Feature flag use cases: Canary releases
Why Feature Flags Are Important for Canary Releases
Canary Releases are a foundational approach for deploying new software versions with high confidence and low risk by exposing the new version to a limited audience. Canary releases are a way to test and release code in different environments for a subset of your audience, which determines which features or versions of the platform people have access to. Often, canary deployments are managed at the load balancer level while feature flags act at the application level. In some instances, rolling out groups of features together behind a feature flag can serve the purpose of a canary deployment.
Gradual rollouts
Roll out the change to a small subset of users before rolling it out to the entire infrastructure and enabling to everyone.
Focused on privacy
Unleash targets attributes locally in the SDK, so private data never changes hands.
Advanced segmentation
Segmented rollouts based on any parameter available in your application context (including tentantID, infrastructure or geo-location).

Challenges and best practices for progressive rollouts
Challenges:
Accurate targeting: Ensuring the right subset of users receives the canary release can be difficult.
Performance Monitoring: Continuously tracking and evaluating the performance of the canary release.
Rollback Management: Efficiently rolling back changes if the canary release encounters issues.
Best Practices:
Advanced Targeting: Use sophisticated targeting tools to accurately identify and release features to a specific subset of users, ensuring that the right users receive the canary release.
Integrated Analytics: Implement robust monitoring and analytics tools to continuously track the performance and stability of the canary release, enabling prompt detection of issues.
Automated Rollback: Develop automated rollback procedures to quickly revert to the previous stable version if the canary release shows adverse effects, minimizing downtime and impact on users.

"We flipped the most important flag we could when we went from our in-house system to Unleash. Right away we found that it was scalable, highly performant, resilient out of the box. And Unleash ended up being 1/3 the cost of our homegrown feature flag solution, while also improving the reliability and scalability of our platform."
