-- The [communication protocol](https://go-kratos.dev/docs/component/api) is based on the HTTP/gRPC through the definition of Protobuf.
-- Abstract [transport](https://go-kratos.dev/en/docs/component/transport/overview) layer are support: [HTTP](https://go-kratos.dev/docs/component/transport/http) / [gRPC](https://go-kratos.dev/docs/component/transport/grpc).
-- Powerful [middleware](https://go-kratos.dev/en/docs/component/middleware/overview) design, support: [Tracing (OpenTelemetry)](https://go-kratos.dev/docs/component/middleware/tracing)、[Metrics (Prometheus is default)](https://go-kratos.dev/docs/component/middleware/metrics)、[Recovery](https://go-kratos.dev/en/docs/component/middleware/recovery) and more.

 - [Registry](https://go-kratos.dev/en/docs/component/registry) interface able to be connected with various other centralized registries through plug-ins.
 - The [standard log interfaces](https://go-kratos.dev/en/docs/component/log) ease the integration of the third-party log libs and logs are collected through the *Fluentd*.
 - The selection of the content [encoding](https://go-kratos.dev/en/docs/component/encoding) is automatically supported by Accept and Content-Type.
 - Multiple data sources are supported for [configurations](https://go-kratos.dev/en/docs/component/config) and dynamic configurations (use atomic operations).
 - In the protocol of HTTP/gRPC, use uniform [metadata](https://go-kratos.dev/en/docs/component/metadata) transfer method.
 - You can define [errors](https://go-kratos.dev/en/docs/component/errors/) in protos and generate enums with protoc-gen-go.
-- You can define [verification rules]([examples/validate](https://go-kratos.dev/docs/component/middleware/validate)) in Protobuf which is supported by HTTP/gRPC service.
-- [Swagger API](https://go-kratos.dev/docs/guide/openapi) generated Automatically and embed Swagger UI endpoint can be started by adding [Swagger plugin](https://github.com/go-kratos/swagger-api).
