# TIR Load Balancer

A TIR Load Balancer takes the web traffic sent to one address and spreads it across the backends you
choose, after checking that they are healthy. You decide which requests go to which backends with
rules, and you can send a small share of traffic to a new version before you move everything to it.
The Load Balancer is available in two regions, Delhi and Chennai.

## Where to find it

In TIR, open your project. In the side menu, under **Compute**, select **Load Balancer**. Every Load
Balancer in the project is listed there, and **Create Load Balancer** starts a new one.

## What you can do

### Create

- [Create a Load Balancer](/tir/tir-load-balancer/how-to/create-a-load-balancer/) of the web
  (HTTP/HTTPS) type, with a plan, the protocols it accepts, and its timeouts.
- [Create a backend group](/tir/tir-load-balancer/how-to/create-a-backend-group/) of VMs, inference
  endpoints, or an [Auto Scaling Group](/tir/tir-auto-scaling/), with its own port, health check, and balancing method.

### Route traffic

- [Add a rule](/tir/tir-load-balancer/how-to/add-a-rule/) to send the requests that match a path,
  method, header, or query parameter to a backend group, or to split them between two groups.

### Secure

- [Use a custom domain and certificate](/tir/tir-load-balancer/how-to/use-a-custom-domain-and-certificate/)
  to serve your own domain over HTTPS, with a free certificate or one you upload.
- [Manage security groups](/tir/tir-load-balancer/how-to/manage-security-groups/) to decide which
  traffic can reach the Load Balancer.

### Operate

- [Edit a Load Balancer](/tir/tir-load-balancer/how-to/edit-a-load-balancer/) to rename it.
- [Change the plan](/tir/tir-load-balancer/how-to/change-the-plan/) to change its capacity
  and turn **High availability** on or off.
- [Monitor a Load Balancer](/tir/tir-load-balancer/how-to/monitor-a-load-balancer/) with charts of
  requests, latency, errors, and healthy backends.
- [View logs](/tir/tir-load-balancer/how-to/view-logs/) of the Load Balancer's output.
- [Set up alerts](/tir/tir-load-balancer/how-to/set-up-alerts/) so your monitoring integrations hear
  about a problem.
- [Delete a Load Balancer](/tir/tir-load-balancer/how-to/delete-a-load-balancer/) when you have finished with it.

### Connect

- [Connect an Auto Scaling Group](/tir/tir-load-balancer/how-to/connect-an-auto-scaling-group/) so
  the Load Balancer sends traffic to the group's VMs.

## Learn how it works

Read [How a load balancer works](/tir/tir-load-balancer/concepts/how-a-load-balancer-works/) for
how a request travels from the Load Balancer to a backend, and
[Billing for TIR Load Balancer](/tir/tir-load-balancer/concepts/billing-options/) for how a Load
Balancer is charged.

## Where to start

Start with [Get started with TIR Load Balancer](/tir/tir-load-balancer/get-started/), which puts a VM
behind a Load Balancer and shows it answering a request. For help with a message, see
[Troubleshooting TIR Load Balancer](/tir/tir-load-balancer/troubleshooting/tir-load-balancer/). The
[TIR Load Balancer FAQ](/tir/tir-load-balancer/faq/) has short answers to common questions. To
create and manage Load Balancers from code, see the [API reference](/api/tir/network/).
