# Collect application data
<note>
  **For Observability Serverless projects**, the **Admin** role or higher is required to send APM data to Elastic. To learn more, refer to [Assign user roles and privileges](/elastic/docs-content/pull/4271/deploy-manage/users-roles/cloud-organization/user-roles#general-assign-user-roles).
</note>


## Language-specific options

Use Elastic APM agents or an OpenTelemetry language SDK to instrument a service in the language its written in:
- [**OpenTelemetry**](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4271/solutions/observability/apm/opentelemetry): OpenTelemetry is an open source set of APIs, SDKs, tooling, and integrations that enable the capture and management of telemetry data from your services and applications. Elastic offers [Elastic Distributions of OpenTelemetry (EDOT)](https://docs-v3-preview.elastic.dev/elastic/opentelemetry/tree/main/reference/edot-sdks), which are customized versions of [OpenTelemetry language SDKs](https://opentelemetry.io/docs/languages/) that are optimized to work with an Elastic backend.
- [**Elastic APM agents**](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4271/solutions/observability/apm/apm-agents): Elastic APM agents are instrumentation libraries written in the same language as your service.

## Service-specific options

Elastic also offers several tools to help you collect data from specific services:
- **Kubernetes**: The Elastic APM attacher for Kubernetes simplifies the instrumentation and configuration of your application pods. Read more in the [APM attacher for Kubernetes docs](https://docs-v3-preview.elastic.dev/elastic/apm-k8s-attacher/tree/main/reference).
- **AWS Lambda Functions**: Helps you monitor your AWS Lambda functions. Read more in the [APM Architecture for AWS Lambda docs](https://docs-v3-preview.elastic.dev/elastic/apm-aws-lambda/tree/main/reference).
- **Jaeger (deprecated)**: Helps you to switch an existing Jaeger setup from the default Jaeger backend to the Elastic Stack. Read more in [Integrate with Jaeger](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4271/solutions/observability/apm/ingest/jaeger).
