How Hulu Seamlessly Launched a Major UI update to 39 Million Customers Using LaunchDarkly

The blog post discusses the importance of feature management in launching major features without compromising customer experience. It highlights how Hulu, a streaming service, outgrew its homebuilt feature flag system and moved to a more scalable and safe release process using LaunchDarkly Custom Attributes at their Galaxy conference. The talk by Senior Software Engineer Matthieu Labbe and Client Architect Dominic Hopton delves into the challenges faced with Hulu's previous feature flag solution, which was stashed in its device config service. They explain how they set up LaunchDarkly users to represent devices rather than people, using custom attributes to identify customers without personal identifiable information (PII). The post concludes by emphasizing that LaunchDarkly users don't have to be people and can be whatever you want them to be, as demonstrated in Hulu's successful launch of their new UI with just a few clicks.
