+The Tracetest Cloud Agent allows you to run Tracetest tests against public facing endpoints without deploying the Tracetest Agent locally. This allows you to trigger tests against public endpoints and collect trace data from either public tracing backends or, alternatively, directly receive incoming OTLP data.

+Tracetest supports two types of tracing backend integrations.
+
+## Native Connection (Polling)
+
+When using a tracing backend integration that supports the native connection, Tracetest will pull telemetry data directly from your tracing backend for every test run.
+
+## OTLP Ingest Endpoint
+
+When using a tracing backend integration that does not support a native connection, or no tracing backend at all, you'll resort to using the Tracetest OTLP ingest endpoint. [Tracetest Agent](/configuration/agent) exposes an OTLP endpoint that listens for trace data on ports `4317` (gRPC) and `4318` (HTTP). As does [Tracetest Cloud Agent](/configuration/cloud-agent), but uses the same TLS port `443` for OTLP ingestion.
+
+## Supported Tracing Backends

+Currently, Tracetest supports the following data stores. Click on the respective data store to view configuration examples:

+- [SigNoz](/configuration/connecting-to-data-stores/signoz)
+- [Sumo Logic](/configuration/connecting-to-data-stores/sumologic)
+
+## Using Tracetest without a Tracing Backend (OTLP ingest endpoint)
+
+Another option is to send traces directly to Tracetest using the OpenTelemetry Collector. And, you don't have to change your existing pipelines to do so.
+
+View [configuration for OpenTelemetry Collector](/configuration/connecting-to-data-stores/opentelemetry-collector) for more details.
+
+## Tracing Backend Configuration Examples
+
+- View the [`examples` folder of the Tracetest GitHub repo](https://github.com/kubeshop/tracetest/tree/main/examples).
+- Follow the [**Recipes**](/examples-tutorials/recipes) for guided walkthroughs of sample use cases.
+
+We will be adding new data stores over the next couple of months - [let us know](https://github.com/kubeshop/tracetest/issues/new/choose) any additional data stores you would like to see us support.
