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 of the web (HTTP/HTTPS) type, with a plan, the protocols it accepts, and its timeouts.
• Create a backend group of VMs, inference endpoints, or an Auto Scaling Group, with its own port, health check, and balancing method.

Route traffic

• 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 to serve your own domain over HTTPS, with a free certificate or one you upload.
• Manage security groups to decide which traffic can reach the Load Balancer.

Operate

• Edit a Load Balancer to rename it.
• Change the plan to change its capacity and turn High availability on or off.
• Monitor a Load Balancer with charts of requests, latency, errors, and healthy backends.
• View logs of the Load Balancer’s output.
• Set up alerts so your monitoring integrations hear about a problem.
• Delete a Load Balancer when you have finished with it.

Connect

• Connect an Auto Scaling Group so the Load Balancer sends traffic to the group’s VMs.

Where to start

Start with Get started with TIR Load Balancer, which puts a VM behind a Load Balancer and shows it answering a request. For help with a message, see Troubleshooting TIR Load Balancer. The TIR Load Balancer FAQ has short answers to common questions. To create and manage Load Balancers from code, see the API reference.
