Steps

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 that’s important?

It's essential for granting our Lambda function the permissions needed to write to DynamoDB.

Great point! Let’s 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! What’s 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.
