Description: Application Load Balancer Health Checks are critical processes that monitor the availability and performance of application servers. Their primary function is to ensure that these servers can efficiently handle incoming traffic without interruptions. These checks are performed by executing periodic tests that evaluate the servers’ responsiveness, the workload they can support, and their overall status. If a server fails to meet established criteria, the load balancer can redirect traffic to other operational servers, thus ensuring a smooth and continuous user experience. This mechanism is essential in high-availability environments, where service disruption can lead to significant losses. Additionally, health checks allow system administrators to identify and resolve issues before they impact end users, contributing to the stability and reliability of applications. In the context of cloud computing, these checks are even more relevant, as they enable dynamic scaling of resources based on demand, optimizing performance and reducing operational costs.
