This document discusses key considerations for advanced load balancing and traffic insights for Kubernetes deployments. It introduces A10's Secure Service Mesh solution for Kubernetes, which provides comprehensive traffic management, security, and visibility for microservices applications. The solution includes A10 Lightning ADC for load balancing and security, the Harmony Controller for centralized management and automation, and an Ingress Controller that integrates these components with Kubernetes. It automates the deployment and configuration of Lightning ADC instances as nodes scale up and down, and provides analytics and insights into application performance and security across the Kubernetes cluster.
