Traditionally, much of the logic handled by Istio has been built directly into applications. Across a fleet of services, managing updates to this communications logic can be a large burden. Istio provides an infrastructure-level solution to managing service communications.

*Application developers*: With Istio managing how traffic flows across their services, developers can focus exclusively on business logic and iterate quickly on new features.

*Service operators*: Istio enables policy enforcement and mesh monitoring from a single centralized control point, independent of application evolution. As a result, operators can ensure continuous policy compliance through a simplified management plane.
