1. Scalability: Google Cloud Load Balancing is designed to handle high traffic loads and scale with demand. It can distribute traffic across multiple regions and auto-scales backend instances based on demand. On the other hand, Traefik is more suitable for smaller deployments and may require additional configuration for high scalability.

2. Load Balancing Algorithms: Google Cloud Load Balancing supports a variety of load balancing algorithms, including round robin, least connection, and IP hash. It provides flexibility in choosing the most appropriate algorithm for specific requirements. Traefik, on the other hand, primarily uses a round robin algorithm by default and may require additional configuration to use other load balancing algorithms.

3. Health Checks: Google Cloud Load Balancing has built-in health checking capabilities to ensure that traffic is only sent to healthy backend instances. It can perform periodic health checks and automatically remove unhealthy instances from the load balancing pool. Traefik also supports health checks, but the configuration and customization options may be different.

4. Proxy Protocol: Google Cloud Load Balancing supports Proxy Protocol, which allows passing client connection information to the backend instances. This can be useful in scenarios where backend applications need to know the original client IP address. Traefik also supports Proxy Protocol, but the configuration may require additional steps.

5. Service Discovery Integration: Traefik has built-in integrations with popular service discovery platforms like Consul, Etcd, and Kubernetes. It can automatically discover and configure routing rules based on the dynamic changes in the service infrastructure. Google Cloud Load Balancing can integrate with service discovery platforms, but it may require additional configuration and setup.

6. Pricing: Google Cloud Load Balancing has a pricing structure based on usage, which includes factors like traffic volume and number of forwarding rules. Traefik, being open-source software, does not have any direct pricing but may involve additional costs for infrastructure and maintenance requirements.

In Summary, Google Cloud Load Balancing provides high scalability, flexible load balancing algorithms, built-in health checks, Proxy Protocol support, and integrations with service discovery platforms. Traefik is more suitable for smaller deployments, primarily uses round robin load balancing, has health check support, and can integrate with service discovery platforms but may require more configuration and setup.
