# Support Load-Balanced Instances

## Description

The Deployment Manager provides customers with tools to manage small- and large-scale installations. This functionality includes the ability to use load balancers to redirect traffic to a particular server when updating or performing maintenance on a server.

## Details

Load balancers sit between the internet and a target group of servers, and the cloud load balancer passes incoming traffic to one of the healthy target instances. A cloud-based target group in AWS can contain one or more target instances, and the target group monitors the health status of each target instance.

From the Deployment Manager, you can bring a target online or offline. The target group marks the offline targets as unhealthy, and the load balancer will not direct traffic to this target. The instance itself is still running and can still receive direct traffic, allowing you to perform maintenance and make updates through the direct URL.

## Supported Application Types

Configuring session affinity ensures that different requests in the same session are not sent to different target instances. When a target is unhealthy the load balancer redirects all session requests to healthy targets, which could cause a broken session. Therefore, the functionality only supports stateless applications, like APIs, having multiple target groups with multiple targets. In the future, this function will also support stateful applications.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://community-test.logicnets.com/release-9/platform-documentation/system-administration/deployment-manager/support-load-balanced-instances.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
