Creating a K8S Cluster The AWS Way

I created a lot of Kubernetes clusters using Terraform and Rancher. However, I prefer to use EKSCTL to create and manage K8S Clusters on AWS. EKSCTL is the official CLI for Amazon EKS and simplifies many things. On the other hand, it is pretty easy to upgrade the clusters, integrate with others features as ClusterAutoescaler, or configure secrets with KMS.

EKSCTL

EKSCTL it is written in Go and makes use of CloudFormation under the hood. Also, it allows us to specify a manifest to replicate if we want to, and we can add it to our codebase just as almost any other IAC does.

Serverless Framework CICD on AWS

I love to use Terraform for creating and managing infrastructure on the cloud. However, there are cases in which I prefer Serverless Framework for creating and deploying resources on AWS, those involve services such as Lambda function and API Gateway. Besides the process can be also automated using Gitlab CICD. I believe Terraform plus Serverless Framework is a perfect combination for Infrastructure as Code and Function as a Service on Amazon Web Services.

Serverless

A serverless architecture is a way to build and run applications and services without having to manage infrastructure. On AWS we can create Lambda, API Gateway, DynamoDB and other resources that are “Serverless”. Some tools can help us to create and deploy our Lambda functions and other infrastructure resources such Serverless Framework, SAM, Terraform, Cloudformation and others.
