**What is Load Balancing?**\
\
Load balancing in Google Cloud Platform (GCP) is a service that distributes incoming network traffic across multiple servers or instances. It ensures high availability and reliability by distributing the workload to prevent any single server from becoming overwhelmed. GCP offers several types of load balancing, including HTTP(S), TCP/SSL, and UDP, to handle different types of traffic. This helps improve application performance and provides seamless scaling to meet varying levels of demand.

**Load balancing** wizard will open, click on the **CREATE LOAD BALANCER** button on the left side

**What is Frontend configuration?**\
\
In GCP, the frontend configuration in load balancing involves setting the IP address and port for incoming traffic, choosing the appropriate protocol (such as HTTP, HTTPS, or TCP), configuring SSL certificates for secure HTTPS connections if needed, and defining host rules to route traffic based on hostnames and paths. This setup ensures that incoming traffic is properly directed to the load balancer.

**What is Backend Configuration?**\
\
In GCP, backend configuration in load balancing involves defining backend services or buckets, specifying instance groups, setting up health checks to monitor backend health, choosing between internal and external load balancing, configuring session affinity, and setting capacity limits for traffic management. This setup ensures efficient distribution and handling of incoming traffic by the backend resources.

**What are the Routing rules?**\
\
In GCP, routing rules for load balancing direct traffic based on hostname and URL path, priority, weighted traffic distribution, and specific HTTP headers or query parameters. These rules ensure efficient and accurate traffic routing to backend services.

Review and finalize all the configurations for the Load Balancer!
