Building a Serverless Employee Management App on AWS: Lambda, DynamoDB, API Gateway, and S3
Serverless does not mean there are no servers. It means you do not manage any servers. AWS handles the infrastructure, the scaling, and the patching. You write code, wire up services, and ship. We are going to build a real working Employee Data application from scratch using a fully serverless architecture on AWS. A user opens a webpage hosted on S3, fills in employee details, hits save, and the data lands in DynamoDB.

Host a Static Website on a Private S3 Bucket Using CloudFront and OAC
Most tutorials on S3 static website hosting tell you to do two things: make the bucket public and enable static website hosting. That gets your site live in five minutes.

If you have worked with Linux workloads on AWS, you already know EFS. It is the go-to shared file system for Linux EC2 instances. But what about Windows? That is where FSx for Windows File Server comes in. Here is the catch though. FSx for Windows does not work in isolation. It has one hard requirement before you can even create it: Active Directory. Without Active Directory, FSx will not let you proceed. That is why this project is not just about FSx. It is a combination of three services working together: AWS Managed Active Directory, FSx for Windows File Server, and Windows EC2 instances. Let us start from the very beginning, understand the problem that Active Directory solves, and then walk through the complete project setup step by step.

Elastic Beanstalk: Deploy Applications Without Worrying About Infrastructure
We have been doing everything manually. We launched EC2 instances, we configured security groups, we deployed applications step by step. But here is the honest question: do you always want to do all of that yourself? What if there was a service that handled all of that for you and you only had to worry about your application?? That is exactly what Elastic Beanstalk is for.
