Multi-region load balancer on GCP

What Is A Multi-Region Load Balancer?

A multi region load balancer is a load balancer that distributes the incoming network traffic across multiple regions to reduce latency and optimize resource utilization for the application. This helps in ensuring high availability and reliability of the application.

What Is Health Check And Why Is It Necessary?

A health check is a regular test to ensure that instances are healthy and will be able to handle incoming traffic. That’s why it is a good practice to perform health check up before load balancer distributes traffic.

How To Create A Global Load Balancer?

To create a global load balancer, in your GCP Console, go to network services, then into Load balancing. Click on create load balancer and select HTTPS Load balancing or TCP/UDP Load balancing and then do the configurations with frontend and backends.

What Is Timeout In Load Balancer?

If the backend service doesn’t return a successful response, the load balancer closes the connection after waiting for 30 sec(generally) . This is known as Load balancer time-out. The timeout depends on the configurations made with the backend.

How Many Rules Can A Load Balancer Have?

The number of rules a load balancer can have depends on the load balancing service and it’s configuration. In GCP the maximum number of rules for a URL Map in the HTTPS Load balancing service is 1000.

Load balancing is necessary in case of any production-ready application. The load balancer is used for load balancing. The main goal here is to distribute the incoming traffic across multiple regions to ensure the high availability and high reliability of an application. Google Cloud Platform provides us with services to configure load balancers for managing traffic on the hosted application. In this article, we will be learning about global load balancers and how we can configure a multi-regional or Global load balancer using Google Cloud Platform.
