Helm is the package manager for Kubernetes. It uses a packaging format called charts to streamline the installation and management of Kubernetes applications, making it the correct tool for deploying the solution.

KubeCtl is the standard command-line interface for interacting with Kubernetes clusters. You use kubectl commands like kubectl get services to view the status of cluster resources, including the external IP addresses assigned to services.

An Ingress Controller is a specialized component that manages external access to the services in a cluster. It provides a single entry point and handles reverse proxying, traffic routing, and TLS/SSL termination for multiple backend microservices, matching the requirement perfectly.

Azure Kubernetes Service (AKS) Documentation:

Helm: "Quickstart: Develop on Azure Kubernetes Service (AKS) with Helm" describes Helm as an open-source packaging tool that helps you install and manage the lifecycle of Kubernetes applications.

KubeCtl: The "Access and identity options for Azure Kubernetes Service (AKS)" page details using kubectl to manage and view resources within the cluster.

Ingress Controller: The section "Create an ingress controller in Azure Kubernetes Service (AKS)" explicitly states that an ingress controller provides advanced features like reverse proxy, configurable traffic routing, and TLS termination.

Official Kubernetes Documentation:

Helm: The official Helm documentation (helm.sh) introduces it as "The package manager for Kubernetes."

KubeCtl: The "Overview of kubectl" page defines it as the command line tool for Kubernetes, used to deploy applications and manage cluster resources.

Ingress Controller: The "Ingress Controllers" documentation explains that an ingress controller is responsible for fulfilling the Ingress resource, which manages external access to services, typically HTTP, and can provide load balancing, SSL termination, and name-based virtual hosting.
