All About GCP Load Balancer Rate Limiting

GCP offers two primary types of load balancers:

• Global Load Balancer
• HTTP(S) Load Balancer

According to our experts, both these load balancers can be configured to implement rate limiting, but they are often used for different purposes.

Furthermore, rate limiting restricts the number of requests or connections that a client or a group of clients can make within a time period.

This control helps prevent clients from overwhelming a service, protect against distributed denial of service (DDoS) attacks, and ensure fair use of resources.

Rate limiting can be beneficial in different cases:

• Protecting our application from abusive or excessive usage by specific clients or IP addresses.
• Preventing DDoS attacks by limiting the number of incoming requests.
• Ensuring fair usage of resources among different clients or tenants.
• Managing API usage quotas.

Configuration of GCP Load Balancer

In GCP, rate limiting for load balancers can be configured via policies, rules, or settings in the load balancer’s configuration.

We can define rate limits based on criteria like the number of requests per second (RPS), and requests per minute, etc.

Furthermore, we can apply rate limiting to specific routes, services, or backend instances. This allows us to control traffic to specific parts of our application.

When a client exceeds the defined rate limits, GCP load balancers can take actions such as:

• Sending an error response to the client.
• Queuing excess requests.
• Redirecting the traffic to a different service or endpoint.
• Logging to monitor and analyze excessive requests.

Additionally, GCP load balancers offer dynamic rate limiting capabilities. This allows us to adjust rate limits based on real-time traffic conditions.

Furthermore, GCP offers monitoring and reporting features that let us track and analyze rate limiting events.
