Harness has introduced an SDK for Erlang and Elixir within its Feature Flags platform, aimed at helping developers create scalable and fault-tolerant distributed applications, particularly suitable for industries like fintech, IoT, and telecom. The SDK allows seamless integration and management of features, following established patterns to ensure smooth deployment. Recognized for its concurrency and reliability, Erlang is complemented by Elixir's modern syntax, making them a popular choice for building distributed systems. Existing users of Harness Feature Flags can expect consistent support and performance, with documentation available to guide new users through the setup process. The process involves using the SDK in code and creating flags within the Harness app to enable progressive delivery and faster deployment.
