-Serverless is the fastest and easiest way to start data streaming. With Serverless clusters, you host your data in Redpanda's VPC, and Redpanda handles automatic scaling, provisioning, operations, and maintenance. This is a production-ready deployment option with a cluster available instantly, and with pay-as-you-go billing, you only pay for what you consume. You can view detailed billing activity for each cluster and edit payment methods on the *Billing* page.

+A Serverless cluster's *Overview* page provides a quick way to get started with a xref:develop:connect/about.adoc[Redpanda Connect] pipeline. Pipelines help you stream data into and out of Redpanda without writing producer/consumer code. If you skip the wizard, you can come back to it here later, or you can create a pipeline anytime on the *Connect* page. The get started wizard helps you:
 
-Create a Kafka client to interact with your cluster. The *Overview* page lists your bootstrap server URL and security settings in the *How to connect - Kafka API* tab. 
+1. Select your data sources: Pick an input data source (to send data into Redpanda) or an output data source (to send data in Redpanda to an external system).
+2. Configure minimal settings. You can fine-tune the pipeline later.
+3. Verify data flow: Open the Redpanda glossterm:topic[] to see messages streaming.
 
-Or, Redpanda can generate a sample application to interact with your cluster. Run xref:reference:rpk/rpk-generate/rpk-generate-app.adoc[`rpk generate app`], and select your preferred programming language. Follow the commands in the terminal to run the application, create a demo topic, produce to the topic, and consume the data back.

 NOTE: Redpanda Serverless is opinionated about Kafka configurations. For example, automatic topic creation is disabled.

 == Supported features
 
 * Redpanda Serverless supports the Kafka API. Serverless clusters work with all Kafka clients. See xref:develop:kafka-clients.adoc[].
 * Serverless clusters support all major Apache Kafka messages for managing topics, producing/consuming data (including transactions), managing groups, managing offsets, and managing ACLs. (User management is available in the Redpanda Cloud UI or with `rpk security acl`.)
