 Dapr addresses a large challenge inherent in modern distributed applications: **Complexity**.
 
-Through an architecture of pluggable components, Dapr greatly simplifies the plumbing behind distributed applications. It provides a **dynamic glue** that binds your application with infrastructure capabilities from the Dapr runtime. For example, your application may require a state store. You could write custom code to target Redis Cache and inject it into your service at runtime. However, Dapr simplifies your experience by providing a distributed cache capability out-of-the-box. Your service invokes a Dapr **building block** that dynamically binds to Redis Cache **component** via a Dapr **configuration**. With this model, your service delegates the call to Dapr, which calls Redis on your behalf. Your service has no SDK, library, or direct reference to Redis. You code against the common Dapr state management API, not the Redis Cache API.
