 The Services Framework introduces a higher-level API for implementing services with NATS. NATS has always been a strong technology on which to build services, as they are easy to write, are location and DNS independent and can be scaled up or down by simply adding or removing instances of the service.
 
-The Services Framework further streamlines their development by providing observability and standardization. The Service Framework allows your services to be discovered, queried for status and schema information without additional work.
