Hosting a Static Website on S3
Unlock Audio Lesson

Today, we'll be starting with hosting a static website on Amazon S3. Can anyone tell me what S3 stands for?
Isnβt it Simple Storage Service?
Exactly! It's a simple storage service provided by AWS. To host a static website, we first prepare our HTML, CSS, and JS files. What do you think the first step is?
We need to create the index.html and error.html files, right?
Correct! We need those two files as part of our website structure. Once thatβs done, whatβs the next step?
We log in to the AWS Console and go to the S3 Dashboard?
Right again! After that, we create a new bucket. What's important about the bucket name?
It has to be globally unique.
Correct! Lastly, weβll set the bucket policy to make our files public. Thatβs crucial for accessing the static website. Letβs summarize what we learned: First, prepare files, then create the bucket, upload files, enable static hosting, and set public access.
Deploying a Web Application Using EC2 and RDS

Next, let's delve into deploying a web application. Who can explain what EC2 stands for?
Elastic Compute Cloud!
Thatβs right! Weβll use EC2 for hosting a web application. First, we need to create an RDS instance. What type of database do we usually choose?
MySQL is commonly used.
Correct! Make sure to set the instance to be publicly accessible if you're testing. After creating the RDS instance, what comes next?
We launch an EC2 instance!
Precisely! When launching, we should choose Amazon Linux. Remember to open the necessary ports. What ports do we need to open?
Ports 22 for SSH and 80 for HTTP.
Well done! That's critical for connectivity. Lastly, we can deploy our web app code. Summarizing, create an RDS instance, launch an EC2 instance, install the required software, and deploy our application.
Implementing AWS Lambda with API Gateway

Now, letβs explore serverless functions using AWS Lambda. So, what exactly do we do with Lambda?
It allows us to run code without provisioning servers!
Exactly! Letβs say we want to process form submissions. Whatβs the first step we take?
We need to create a DynamoDB table for submissions?
Good! We create a table called FormSubmissions with a primary ID key. Now, can anyone explain how we create the Lambda function?
We choose a programming language, like Node.js or Python and set the IAM role to allow Lambda write access to our DynamoDB table.
Exactly! Finally, we can set up an API Gateway to trigger our Lambda function. What should we enable for our API?
We enable CORS for better integration!
Perfect! To recap: We create a DynamoDB table, develop a Lambda function, and set up an API Gateway.
Setting Up a CI/CD Pipeline
Unlock Audio Lesson

Lastly, letβs cover CI/CD pipelines. Who can tell me why CI/CD is important?
It automates code deployments and improves efficiency!
Exactly! To start, we need a code repository. What do we use to host our code?
GitHub is a popular choice.
Right! After pushing code to GitHub, we create a CodePipeline. What are the components of a CodePipeline?
Source, build, and deploy stages!
Exactly! And what do we configure for deployments?
We can deploy to S3 for static sites or CodeDeploy for EC2 instances.
Correct! Letβs summarize: we set up a GitHub repository, create a CodePipeline with source, build, and deploy stages.
Introduction & Overview
Read a summary of the section's main ideas. Choose from Basic, Medium, or Detailed.
Quick Overview
Standard
This section focuses on real-world projects in AWS, guiding learners through hosting a static website, deploying a web application, implementing serverless functions, and setting up automated CI/CD pipelines. These practical applications aim to ensure students gain confidence while using AWS services.
Detailed
Detailed Summary
This section serves as the foundational goal for the upcoming AWS projects detailed in Chapter 9. It emphasizes applying previously acquired theoretical knowledge into a hands-on, practical learning environment. The projects are structured to help learners build confidence while using various AWS services by solving actual challenges related to web hosting and application deployment.
The projects include:
- Hosting a Static Website on S3: Step-by-step guidance on creating and managing a static website using Amazon S3. Learners will understand how to prepare website files, create a unique S3 bucket, enable public access, and set up a static website hosting configuration.
- Deploying a Dynamic Web Application Using EC2 and RDS: This segment teaches the deployment of a full-stack PHP and MySQL application, covering RDS instance creation, EC2 setup, and connecting the application to a database.
- Implementing a Serverless Function with AWS Lambda: Students will learn to create a Lambda function for processing and storing data in DynamoDB, coupled with API Gateway setup.
- Setting Up a CI/CD Pipeline: Finally, the section covers creating an automated deployment pipeline from GitHub to AWS services, reinforcing students' ability to set up a complete deployment environment.
Through these projects, students will gain hands-on experience with essential AWS services like S3, EC2, RDS, Lambda, and CodePipeline, which is crucial for managing real-world applications in the cloud.

Introduction to the Goal
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Host a fully functional static website (HTML/CSS/JS) on S3 with public access.
Detailed Explanation
The goal here is to create a static website using HTML, CSS, and JavaScript and host it on Amazon S3, which stands for Simple Storage Service. This allows users to access the website publicly over the internet. Static websites are ideal for displaying content that does not change frequently and do not require server-side processing.
Examples & Analogies
Think of Amazon S3 like a digital file cabinet. Just as you store documents and photos in a cabinet for easy access, you can store your website files in S3. When someone wants to view your website, they simply open the cabinet (your S3 bucket) and access the files inside.
Specific Steps to Achieve the Goal

β
Steps:
1. Prepare your website files:
β Create an index.html and error.html page.
2. Login to AWS Console and go to the S3 Dashboard.
3. Create a new bucket:
β Bucket name must be globally unique.
β Disable "Block all public access" under Permissions.
4. Upload website files to the bucket.
5. Enable static website hosting:
β Go to the bucket's Properties tab.
β Enable Static website hosting and set index/error documents.
6. Set Bucket Policy to make files public:
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "PublicReadGetObject",
"Effect": "Allow",
"Principal": "",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::your-bucket-name/"
}
]
}
7. Access your website using the S3 website endpoint.
Detailed Explanation
Each step outlines what you need to do to successfully host your static website:
1. First, you need to prepare your website files. Create essential HTML files like index.html (the main page) and error.html (for handling errors).
2. Log in to your AWS Console, which is the web interface for managing your AWS services, and navigate to the S3 dashboard, where you will manage your buckets.
3. You will create a new S3 bucket (a container for your files). Remember, the name must be unique across all AWS users.
4. After creating the bucket, upload your website files to it.
5. To make the files accessible as a website, enable static website hosting in the bucket settings and specify which files to use as the index and error documents.
6. Set the proper permissions using a bucket policy to ensure your files are publicly readable. This policy snippet allows anyone to access your files.
7. Finally, you will be able to access your website using the S3 endpoint provided by AWS, basically a URL pointing to your hosted files.
Examples & Analogies
Imagine you're setting up your own shop. You need to prepare the items you want to display (your HTML pages), sign a lease for the shop location (create the S3 bucket), make sure the shop is open to customers (enable public access), decorate the shop (upload files), and put a sign outside to guide customers (enable website hosting). Once everything is done, people can come in and buy β or in this case, view your website!
