--- title: Service --- A `Service` is an abstraction of an API (which can also be understood as a set of Route abstractions). It usually corresponds to the upstream service abstraction. Between `Route` and `Service`, usually the relationship of N:1, please see the following image. ![service-example](../../../assets/images/service-example.png) Different Route rules are bound to a Service at the same time. These Routes will have the same upstream and plugin configuration, reducing redundant configuration. The following example creates a Service that enables the current-limit plugin, and then binds the Route with the id of `100` and `101` to the Service. ```shell # create new Service $ curl http://127.0.0.1:9080/apisix/admin/services/200 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' { "plugins": { "limit-count": { "count": 2, "time_window": 60, "rejected_code": 503, "key": "remote_addr" } }, "upstream": { "type": "roundrobin", "nodes": { "39.97.63.215:80": 1 } } }' # create new Route and reference the service by id `200` curl http://127.0.0.1:9080/apisix/admin/routes/100 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' { "methods": ["GET"], "uri": "/index.html", "service_id": "200" }' curl http://127.0.0.1:9080/apisix/admin/routes/101 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' { "methods": ["GET"], "uri": "/foo/index.html", "service_id": "200" }' ``` Of course, we can also specify different plugin parameters or upstream for Route. Some of the following Routes have different current-limit parameters. Other parts (such as upstream) continue to use the configuration parameters in Service. ```shell curl http://127.0.0.1:9080/apisix/admin/routes/102 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' { "uri": "/bar/index.html", "id": "102", "service_id": "200", "plugins": { "limit-count": { "count": 2000, "time_window": 60, "rejected_code": 503, "key": "remote_addr" } } }' ``` Note: When both Route and Service enable the same plugin, the Route parameter has a higher priority than Service.
