Premium Tier with a global load balancer is more expensive and unnecessary for an application that is regionally deployed and serves only regional users.

Premium Tier with a regional load balancer is more expensive than Standard Tier, as Premium Tier provides global routing capabilities that are not needed for a strictly regional service.

Standard Tier with a global load balancer is not a valid configuration; global load balancers on Google Cloud primarily leverage the Premium Tier network.

The Standard Network Tier is designed for regional traffic and offers a more cost-effective option than the Premium Tier, which is optimized for global reach. A regional load balancer is sufficient for an application that is deployed within a single region and exclusively serves users within that same region, avoiding the higher costs associated with global load balancers and the Premium Tier when not needed.
