Hosting a Static Website on Amazon S3

Today, we'll start by discussing how to host a static website using Amazon S3. Does anyone know what S3 stands for?
I think it stands for Simple Storage Service.
That's right! S3 is a storage service optimized for affordability and scalability. Now, could anyone list the steps involved in hosting a static website?
You need to prepare your website files first, like creating an index.html.
Excellent! After that, we must create a unique bucket in the S3 Dashboard. Can anyone tell me why the bucket name must be globally unique?
So that there are no conflicts with other S3 users?
Correct! Once the bucket is created, weβve got to upload our files and enable static website hosting. Remember, we also have to set a Bucket Policy to allow public access. Can anyone repeat the JSON structure for the policy?
It allows public read access for all objects in the bucket.
Very good! Finally, we access our website using the S3 endpoint. To sum up, we learned how to prepare website files, create an S3 bucket, upload files, enable hosting, set permissions, and access the endpoint.
Deploying a Web Application Using EC2 and RDS

Next, we will discuss how to deploy a web application using EC2 and RDS. Who can explain what EC2 is?
EC2 stands for Elastic Compute Cloud, which provides scalable virtual servers.
Exactly! Now, can anyone summarize the first few steps we take when setting up an RDS instance?
You choose MySQL as the database engine and make sure it's publicly accessible for testing.
Well done! And what about launching an EC2 instance?
You select Amazon Linux 2 and configure security groups to open specific ports.
Exactly! You'll then SSH into your EC2 instance and deploy your web application code. Don't forget the database connection! After testing, why do you think this hands-on experience is vital?
It helps us understand how to link our server and database together to create a functional application.
Precisely! Connecting these components is essential for full-stack development. Hence, we see the critical interplay of these AWS services.
Implementing a Serverless Function with AWS Lambda

Now, let's look at serverless architecture using AWS Lambda. Does anyone know what serverless means?
It means we don't manage the server; AWS handles it for us.
Great! Can someone outline how we will store form input using DynamoDB in this project?
We create a DynamoDB table called FormSubmissions with an id as the primary key.
Exactly! After that, we create a Lambda function. What programming languages can we choose for writing our Lambda function?
We can use Node.js or Python.
Yes! And, it's essential to attach the correct IAM role for permissions. Let's review how to write the Lambda function code. Does anyone want to explain the flow?
We load the incoming data, save it in DynamoDB, and return a success response.
Exactly! This allows us to process input forms dynamically without needing servers!
Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
The objective of this section is to bridge the gap between theory and practice by engaging in hands-on AWS projects, including hosting websites, deploying applications, implementing serverless functions, and setting up CI/CD pipelines, thereby building confidence in using AWS services.
Detailed
Objective
Overview
The objective of this section is to provide learners with the opportunity to apply theoretical concepts learned from previous chapters to practical, hands-on AWS (Amazon Web Services) projects. These projects are curated to help you build confidence in utilizing AWS services as you tackle real-world problems and deploy functional applications and infrastructure.
Significance
By engaging in these projects, learners will gain valuable experience that serves as the foundation for managing scalable and maintainable applications on AWS. Starting with simple tasks such as hosting static websites, learners can progressively advance to more complex challenges like deploying web applications, implementing serverless architectures with AWS Lambda, and establishing CI/CD (Continuous Integration/Continuous Deployment) pipelines.
Learning Outcomes
Each project is designed to solidify your understanding of key AWS services, giving you practical skills to address common challenges faced in cloud environments. By the end of these projects, you should feel empowered to confidently deploy and manage applications in the cloud.

Chapter Content
To apply theoretical knowledge from previous chapters into practical, hands-on AWS projects.
Detailed Explanation
The primary aim of this objective is to take the concepts and theories learned in the previous chapters and put them into practice through real AWS projects. This allows students to understand how to use AWS services effectively in real-world scenarios, reinforcing their learning through hands-on experience.
Examples & Analogies
Think of it like learning to ride a bike. First, you learn about balance and steering (theory), but itβs only when you actually hop on the bike and start pedaling that you truly understand how to ride.

These step-by-step projects are designed to help you become confident in using AWS services by solving real-world problems and deploying actual applications and infrastructure.
Detailed Explanation
This chunk emphasizes the importance of engaging in practical projects, which are structured in a step-by-step manner. By following these projects, students will gain confidence in utilizing AWS services to address real-world challenges, thereby acquiring the skills needed to deploy applications and manage infrastructure effectively.
Examples & Analogies
Imagine you are in a cooking class. Watching a chef demonstrate a dish is helpful, but when you step into the kitchen and cook it yourself, you learn how to handle the tools, the ingredients, and perfect the recipe, just as these projects guide you in applying AWS.
