Unlock Audio Lesson
Signup and Enroll to the course for listening the Audio Lesson
Today, we will learn how to host a static website on Amazon S3. Can anyone tell me what a static website is?
A static website serves the same content to all users and doesn't require server-side processing.
Exactly! Now, the first step is to prepare your website files. What do we need to create?
We need an index.html and error.html page.
Great! After preparing your files, you need to log in to the AWS Console and go to the S3 Dashboard. What do we do next?
We create a new bucket and ensure the name is globally unique.
Exactly! And remember to disable 'Block all public access' for permissions. Can someone summarize the steps we just discussed?
We create the bucket, upload the website files, enable static website hosting, and set the bucket policy to make the files public.
Well done! In summary, hosting a static website on S3 involves these essential steps: preparing files, creating a bucket, uploading, enabling hosting, and setting permissions.

Next, let's discuss deploying a dynamic web application. What two key AWS services will we be using?
Amazon EC2 for hosting the application and Amazon RDS for the database.
Correct! The first step is to create an RDS instance. What should we select for the database type?
We should choose MySQL.
Yes! Ensure we're using Free Tier settings. After that, what is the next step involving the EC2 instance?
We launch an EC2 instance, selecting Amazon Linux 2 and using t2.micro.
Exactly! After launching EC2, what commands do we need to run to set up our web server and PHP?
We use 'sudo yum update -y' followed by installing httpd and PHP packages.
Great job! Finally, how do we test our connection to RDS?
We upload our web app code and check the connection using the EC2 public IP.
Exactly! We've covered hosting applications on EC2 and managing databases with RDS. Let's summarize the key steps.

Now we will learn about AWS Lambda for serverless applications. What do we need to initially set up?
We need a DynamoDB table for storing our form submissions.
Absolutely! The next step involves creating the Lambda function. Which programming languages can we choose from?
We can choose either Node.js or Python.
Exactly! After that, we must attach IAM roles. Can anyone explain why thatβs important?
It's essential for granting our Lambda function the permissions needed to write to DynamoDB.
Great point! Letβs talk about the function code briefly. What does the Lambda function do with the input data?
It processes the input and saves it to the DynamoDB table.
Exactly! Lastly, we create an API Gateway. What is its main function?
It creates an endpoint to trigger the Lambda function when data is submitted.
Correct! In summary, creating a serverless function involves establishing a DynamoDB table, creating a Lambda function, writing the code, and setting up an API Gateway.

Finally, we will discuss CI/CD pipelines. Who can tell me what CI/CD stands for?
Continuous Integration and Continuous Deployment.
Exactly! The first step in setting this up is to prepare our code repository. What should we do?
We need to push our website or app code to a GitHub repository.
Correct! Next, how do we create the CodePipeline?
We select GitHub as the source and use AWS CodeBuild for building.
Good! And when we deploy, what are the options for deployment?
We can deploy to S3 for static sites or use CodeDeploy for EC2 applications.
Exactly! Whatβs the role of the appspec.yml file in CodeDeploy?
It specifies how to deploy our application, including the source and destination directories.
Well done! In summary, setting up a CI/CD pipeline involves preparing your code, creating a pipeline with source and build settings, and configuring CodeDeploy.

- Prepare your website files:
β Create an index.html and error.html page.
Detailed Explanation
The first step involves preparing the files necessary for your static website. You need to create two essential HTML files: 'index.html' serves as the main page of your website, while 'error.html' provides a custom error page for instances when a user tries to access a non-existent page. This ensures a good user experience even when errors occur.
Examples & Analogies
Think of 'index.html' like the front door of your store that welcomes customers, while 'error.html' is a sign you put up to guide lost customers back to the right path, keeping them informed and reducing their frustration.
Setting Up an Amazon S3 Bucket

Signup and Enroll to the course for listening the Audio Book
- Login to AWS Console and go to the S3 Dashboard.
- Create a new bucket:
β Bucket name must be globally unique.
β Disable "Block all public access" under Permissions.
Detailed Explanation
In this step, you log into the AWS management console, navigate to the Amazon S3 section, and create a new storage bucket. Make sure to choose a unique name, as no two buckets can share the same name globally. Additionally, you'll need to adjust the permissions by disabling the 'Block all public access' option, which allows your website to be accessed by anyone on the internet.
Examples & Analogies
Creating an S3 bucket is similar to getting your storefront ready. You have to choose a unique name for your storefront that no one else has, and then ensure the doors are unlocked so that customers can freely enter and browse your offerings.
Uploading Website Files

- Upload website files to the bucket.
Detailed Explanation
Once your bucket is ready, the next step is to upload the HTML files (index.html and error.html) you prepared earlier. This can typically be done using the AWS Management Console's simple drag-and-drop feature or through a file upload option provided in the S3 interface.
Examples & Analogies
Think of uploading your files like stocking your store with products. Once your storefront is built, you need to fill it with items (in this case, website files) that customers can browse and purchase (or in web terms, view).
Enabling Static Website Hosting

- Enable static website hosting:
β Go to the bucket's Properties tab.
β Enable Static website hosting and set index/error documents.
Detailed Explanation
To make your bucket serve as a static website, you need to enable the static website hosting feature in the bucket properties. When doing this, specify which documents to use for your index page (index.html) and error page (error.html). This tells AWS how to handle requests for your website.
Examples & Analogies
Enabling static website hosting is like turning on the lights in your store. When the lights are on, customers can enter and see your products; by enabling this feature, you're making your website accessible to visitors.
Setting Bucket Policy for Public Access

- 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/"
}
]
}
Detailed Explanation
To allow users to access your uploaded files, you need to set a bucket policy that makes them publicly readable. This JSON structure defines permissions for who can access your bucket and includes 'Allow' for everyone ('Principal':'*') to read the objects stored, which is fundamental for a public website.
Examples & Analogies
This step is akin to putting up a sign on your storefront that says 'Everyone Welcome!' By setting up a public access policy, you're inviting anyone to visit and view your content.
Accessing Your Website

- Access your website using the S3 website endpoint.
Detailed Explanation
The final step involves accessing your static website through the S3 website endpoint. This is a special URL provided by AWS that directs users to your website. Simply enter that URL into any web browser to view your site live.
Examples & Analogies
Accessing your website is like giving your customers the address of your store. Once they have the address (the S3 endpoint), they can easily find and visit your shop at any time.
