Load balancers are critical components in modern web infrastructure. They distribute incoming network traffic across multiple servers to ensure no single server becomes overwhelmed, thereby improving responsiveness and availability of applications. Load balancers can be hardware-based or software-based, and they play a crucial role in scaling applications and maintaining performance.
The LoadBalancerRequestRateLimitExceeded alert indicates that the request rate to the load balancer has surpassed the configured limits. This can lead to dropped requests and degraded performance for end-users.
This alert is triggered when the number of requests per second (RPS) exceeds the threshold set in the load balancer's configuration. This threshold is designed to protect backend resources from being overwhelmed by too many requests at once. When this limit is breached, it can result in throttling or rejection of incoming requests, leading to potential downtime or slow response times for users.
There are several reasons why this alert might be triggered:
Addressing this alert involves both immediate and long-term solutions to ensure your load balancer can handle the traffic effectively.
By understanding the root cause of the LoadBalancerRequestRateLimitExceeded alert and implementing both immediate and long-term solutions, you can ensure that your load balancer effectively manages traffic and maintains application performance. Regular monitoring and adjustments are key to preventing future occurrences of this alert.
