+title: Agent Server
+---
+
+LangSmith Deployment's **Agent Server** offers an API for creating and managing agent-based applications. It is built on the concept of [assistants](/langsmith/assistants), which are agents configured for specific tasks, and includes built-in [persistence](/oss/langgraph/persistence#memory-store) and a **task queue**. This versatile API supports a wide range of agentic application use cases, from background processing to real-time interactions.
+
+Use Agent Server to create and manage [assistants](/langsmith/assistants), [threads](/oss/langgraph/persistence#threads), [runs](/langsmith/assistants#execution), [cron jobs](/langsmith/cron-jobs), [webhooks](/langsmith/use-webhooks), and more.
+
+<Tip>
+**API reference**<br></br>
+For detailed information on the API endpoints and data models, refer to the [API reference docs](https://langchain-ai.github.io/langgraph/cloud/reference/api/api_ref.html).
+</Tip>
+
+To use the Enterprise version of the Agent Server, you must acquire a license key that you will need to specify when running the Docker image. To acquire a license key, [contact our sales team](https://www.langchain.com/contact-sales).
+
+You can run the Enterprise version of the Agent Server on the following LangSmith [platform](/langsmith/platform-setup) options:
+
+- [Cloud](/langsmith/cloud)
+- [Hybrid](/langsmith/hybrid)
+- [Self-hosted](/langsmith/self-hosted)
+
+## Application structure
+
+To deploy an Agent Server application, you need to specify the graph(s) you want to deploy, as well as any relevant configuration settings, such as dependencies and environment variables.
+
+Read the [application structure](/langsmith/application-structure) guide to learn how to structure your LangGraph application for deployment.
+
+## Parts of a deployment
+
+When you deploy Agent Server, you are deploying one or more [graphs](#graphs), a database for [persistence](/oss/langgraph/persistence), and a task queue.
+
+### Graphs
+
+When you deploy a graph with Agent Server, you are deploying a "blueprint" for an [Assistant](/langsmith/assistants).
+
+An [Assistant](/langsmith/assistants) is a graph paired with specific configuration settings. You can create multiple assistants per graph, each with unique settings to accommodate different use cases
+that can be served by the same graph.
+
+Upon deployment, Agent Server will automatically create a default assistant for each graph using the graph's default configuration settings.
+
+<Note>
+We often think of a graph as implementing an [agent](/oss/langgraph/workflows-agents), but a graph does not necessarily need to implement an agent. For example, a graph could implement a simple
+chatbot that only supports back-and-forth conversation, without the ability to influence any application control flow. In reality, as applications get more complex, a graph will often implement a more complex flow that may use [multiple agents](/oss/langchain/multi-agent) working in tandem.
+</Note>
+
+### Persistence and task queue
+
+Agent Server leverages a database for [persistence](/oss/langgraph/persistence) and a task queue.
+
+[PostgreSQL](https://www.postgresql.org/) is supported as a database for Agent Server and [Redis](https://redis.io/) as the task queue.
+
+If you're deploying using [LangSmith cloud](/langsmith/cloud), these components are managed for you. If you're deploying Agent Server on your [own infrastructure](/langsmith/self-hosted), you'll need to set up and manage these components yourself.
+
+For more information on how these components are set up and managed, review the [hosting options](/langsmith/platform-setup) guide.
