In a containerized environment, the use of a software load balancer (ELB) offers multiple advantages. First, it simplifies the process of external access to container workloads by enabling seamless integration with ELB through associated Ingress, thereby enhancing overall efficiency by allowing direct access to container workloads. In disaster recovery scenarios, the ELB acts as the traffic entry point, ensuring even distribution of traffic across multiple container instances, which further enhances system stability. Additionally, it meets the isolation requirements of project teams by providing each team with a dedicated load balancer, allowing for independent configuration and management of resources.
