# Backend and UI
|
|
|
|
SkyWalking backend distribution package includes following parts
|
|
1. **bin/cmd scripts**, in `/bin` folder. Include startup linux shell and Windows cmd scripts for Backend
|
|
server and UI startup.
|
|
1. **Backend config**, in `/config` folder. Include setting files of backend, which are `application.yml`,
|
|
`log4j.xml` and `alarm-settings.yml`. Most open settings are in these files.
|
|
1. **Libraries of backend**, in `/oap-libs` folder. All jar files of backend are in it.
|
|
1. **Webapp env**, in `webapp` folder. UI frontend jar file is in here and its `webapp.yml` setting file.
|
|
|
|
## Quick start
|
|
Requirement: **JDK8 to JDK12 are tested**, other versions are not tested and may or may not work.
|
|
|
|
Before you do quick start, you should know, quick start is to run skywalking backend and UI for preview
|
|
or demonstration. In here, performance and long-term running are not our goals.
|
|
|
|
Want to deploy to product/test env? Go to [Backend and UI deployment documents](#deploy-backend-and-ui)
|
|
|
|
You can use `bin/startup.sh`(or cmd) to startup backend and UI in default settings, which include the following
|
|
things you need to know.
|
|
- Storage, use H2 by default, in order to make sure, don't need further deployment.
|
|
- Backend listens `0.0.0.0/11800` for gRPC APIs and `0.0.0.0/12800` for http rest APIs.
|
|
In Java, .NetCore, Node.js, Istio agents/probe, set the gRPC service address to `ip/host:11800`.
|
|
(ip/host is where the backend at)
|
|
- UI listens `8080` port and request `127.0.0.1/12800` to do GraphQL query.
|
|
|
|
## Deploy Backend and UI
|
|
After the quick start, you should want to deploy the backend and UI in the distributed env.
|
|
Before that, you should know how agent/probe, backend, UI communicate with each other.

|
|
|
|
- All native agents and probes, either language based or mesh probe, are using gRPC service(`core/default/gRPC*` in `application.yml`) to report
|
|
data to backend. Also, jetty service supported in JSON format.
|
|
- UI uses GraphQL(HTTP) query to access backend also in Jetty service(`core/default/rest*` in `application.yml`).
|
|
|
|
Now, let's continue with the backend and UI setting documents.
