Welcome to Day 8 of our End to End LLMOps Pipeline series! In the last part, we used kube-score to ensure that our Kubernetes manifests were following best practices. Now that our manifests are validated, it's time to deploy them. For this deployment, we'll be using AWS Elastic Kubernetes Service (EKS), a managed Kubernetes service provided by AWS.

What is AWS EKS?
AWS EKS is a fully managed Kubernetes service that simplifies the process of running Kubernetes clusters in the cloud. It handles the Kubernetes control plane, node management, patching, and upgrades, allowing businesses to focus on their applications rather than managing Kubernetes infrastructure. EKS integrates seamlessly with AWS services, providing a secure and scalable environment for your Kubernetes workloads.

Key Features of AWS EKS
Scalability and Reliability: EKS integrates with AWS security and services, ensuring robust scalability and reliability. It automates load balancing, logging, monitoring, and HTTPS routing, giving you a fully compatible Kubernetes environment curated by AWS.
Security Configuration: AWS EKS integrates tightly with IAM for VPC isolation, ensuring least-privilege access. It also works seamlessly with AWS KMS for encryption, providing a secure Kubernetes environment.

Use Cases
EKS is ideal for a variety of workloads, including microservices architecture, batch processing, and scalable applications. It is particularly well-suited for businesses needing managed clusters at scale, with integrated security and compliance support.
Cost Management
Amazon EKS charges for each deployed cluster, in addition to the resources your applications consume. To optimize costs, you should monitor resource usage and scale your applications effectively to avoid unnecessary expenses.

Getting Started with AWS EKS
You can start with AWS EKS by using the AWS Management Console, CLI, or SDKs. AWS provides extensive documentation and tutorials to help you set up and configure clusters quickly. Below is an overview of the steps involved in setting up an EKS cluster:
Create an EKS Cluster: Use the AWS Management Console, AWS CLI, or AWS CloudFormation to create an EKS cluster.
Configure kubectl: Ensure that kubectl is configured to interact with your EKS cluster.
Deploy Kubernetes Resources: Use kubectl to deploy your Kubernetes resources to the EKS cluster.

Example Command to Configure kubectl
Once your EKS cluster is set up, you need to configure kubectl to connect to it. Use the following command:

aws eks update-kubeconfig --region $AWS_REGION --name $EKS_CLUSTER_NAME

Command Explanation:

aws eks update-kubeconfig: This command updates your local kubeconfig file with the necessary configuration to connect to your EKS cluster.
--region $AWS_REGION: Specifies the AWS region where your EKS cluster is running.
--name $EKS_CLUSTER_NAME: The name of the EKS cluster you want to connect to. Replace $EKS_CLUSTER_NAME with the actual name of your cluster.

AWS EKS simplifies Kubernetes management, allowing you to focus on your application rather than the infrastructure. By leveraging EKS, you gain the benefits of a fully managed service with the scalability, security, and integration that AWS provides.
