what is IT Networking ? explained here .

IT networking is the practice of connecting multiple computing devices together so they can exchange data, share resources, and communicate with each other . It forms the invisible digital backbone of our world, powering everything from your home Wi-Fi to corporate cloud environments and the global internet. Core Components of a Network To understand how an IT network operates, it helps to look at its fundamental building blocks: Nodes (End Devices) : Any physical device connected to the network that sends or receives information. Examples include laptops, smartphones, servers, printers, and IoT devices like smart TVs. Links (Transmission Media) : The channels used to connect the nodes together. These can be wired (like Ethernet and copper cables or high-speed fiber optics) or wireless (like Wi-Fi, Bluetooth, and cellular signals). Network Devices : Specialized hardware that directs traffic across the network. Switches : Connect multiple devices together within the same local network....

How to setup host based routing in eks with ingress controller ?

Of course. To set up host-based routing in EKS, you define an Ingress resource with multiple rules. Each rule specifies a hostname (e.g., app1.example.com) and maps it to a corresponding backend Service. The AWS Load Balancer Controller reads this resource and provisions an Application Load Balancer (ALB) to route traffic based on the Host header of incoming requests. Here’s a complete guide. Prerequisites A running Amazon EKS cluster. kubectl configured to connect to your cluster. The AWS Load Balancer Controller installed in your cluster. This is the standard Ingress controller for EKS. A registered domain name (e.g., your-domain.com) that you can manage. Step 1: Deploy Sample Applications First, let's deploy two different applications to route traffic to: a "coffee" app ☕ and a "tea" app ЁЯН╡. Each application will have a Deployment and a Service. Save the following YAML as apps.yaml: # apps.yaml # --- Coffee App --- apiVersion: apps/v1 kind: Deployment metadat...
