Introduction to Static Website Hosting
Unlock Audio Lesson
Signup and Enroll to the course for listening the Audio Lesson
Today, we will explore how to host a static website using Amazon S3. Can anyone summarize what S3 is and its main purpose?
S3 stands for Simple Storage Service, used for storing and retrieving any amount of data at any time.
Exactly! So what are the first steps in hosting our website on S3?
We need to prepare our website files first, like creating index.html and error.html.
Correct! Remember the acronym ICE - 'Index, Create, Enable' for steps: Index file preparation, Create a new bucket, and Enable static website hosting. What comes next?
We should log in to the AWS Console and create a new S3 bucket.
Yes! Also, remember to disable public access settings to make the site accessible to everyone. Let's summarize: Preparing files, creating a bucket, enabling hosting. What do we set after creating the bucket?
We upload our website files and create a bucket policy to allow public access!
Deploying a Web Application with EC2 and RDS

Next, letβs discuss deploying a dynamic web application. What are the first steps to set this up using EC2 and RDS?
We start by creating an RDS instance, likely using MySQL.
Correct! Organize this step with the acronym R.E.A.D - RDS, EC2, Application deployment, and Database connection. What settings do we need on RDS?
Use Free Tier settings, set a username, and make it publicly accessible for testing.
Well done! Next, we need to launch our EC2 instance. What specifications should we follow?
We should choose the Amazon Linux 2, using Free Tier t2.micro and open ports 22 for SSH and 80 for HTTP.
Excellent! And once we have our EC2 instance ready, what follows?
We connect to the EC2 instance and install the web server and MySQL client, and then deploy our web app code.
Working with Serverless Functions in AWS Lambda

Let's talk about serverless functions using Lambda. What do we need to set up our DynamoDB table first?
We need to create a DynamoDB table named 'FormSubmissions' with an 'id' as the primary key.
Great! Remember the acronym F.L.O.W - Form, Lambda, Output, Write. Whatβs next after our table is ready?
Then we create the Lambda function, selecting either Node.js or Python.
Exactly! Itβs also important to attach an IAM role with DynamoDB write access. How do we write our function code?
By importing libraries, creating a handler to store the data from the form into DynamoDB.
Spot on! Then we create an API Gateway for a POST endpoint to trigger our Lambda function. Can anyone tell me how we test this?
By using Postman or a frontend form to send requests!
Setting Up a CI/CD Pipeline
Unlock Audio Lesson
Signup and Enroll to the course for listening the Audio Lesson
Now, letβs discuss CI/CD pipelines. Whatβs the first step in setting this up?
We need to prepare our code repository and push our code to GitHub.
Exactly! Let's remember the acronym C.I.P - Code integration and Pipeline. What follows next?
We create a CodePipeline, integrating GitHub OAuth and optionally using AWS CodeBuild.
Yes! After creating the CodePipeline, what do we need to set up for deployments?
We can either deploy it to S3 for static sites or use CodeDeploy for EC2 instances.
Right! Finally, how do we test our pipeline?
By pushing a new commit to GitHub and observing the deployment process.
Introduction & Overview
Read a summary of the section's main ideas. Choose from Basic, Medium, or Detailed.
Quick Overview
Standard
This section details the objectives for various AWS projects aimed at consolidating the learner's understanding of AWS services through real-world application, focusing on tasks such as hosting websites, deploying web applications, creating serverless functions, and setting up CI/CD pipelines.
Detailed
Goal
This section articulates the goals of practical application of AWS services through four distinct projects. Each project aims to enhance understanding and competence in using AWS in solving real-world problems and deploying functional applications. The projects range from hosting static websites on S3 to deploying dynamic web applications on EC2 and RDS, implementing serverless architecture with Lambda, and establishing CI/CD pipelines for automated deployments. The overarching goal is to equip learners with the confidence to build, secure, and manage applications in the cloud effectively.

Project 1: Hosting a Static Website on Amazon S3
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Goal:
Host a fully functional static website (HTML/CSS/JS) on S3 with public access.
Detailed Explanation
This chunk outlines the main objective of the first project under the broader goal of using AWS services. The goal is to host a static website using S3, a storage service provided by AWS which allows you to store and retrieve any amount of data, at any time, from anywhere on the web. A static website consists of fixed content like HTML, CSS, and JavaScript files, which are served as they are stored without any server-side processing.
Examples & Analogies
Think of S3 as a digital filing cabinet where each drawer can hold various folders (your website files). When someone wants to view your website, they simply open the drawer and grab the folder containing your HTML, CSS, and JS files.
Project 2: Deploying a Web Application Using EC2 and RDS

Goal:
Deploy a dynamic web app (e.g., PHP + MySQL) using Amazon EC2 and Amazon RDS.
Detailed Explanation
In this chunk, the objective is to deploy a dynamic web application. Unlike static websites, dynamic web apps often require a backend server (like EC2) to process input and interact with a database (like RDS) to manage data. This allows for more complex functionalities, such as user logins, data submission through forms, and real-time updates.
Examples & Analogies
Imagine setting up a restaurant where a server (EC2) takes orders and retrieves them from the kitchen (RDS) to serve customers. The server can also add new menu items or update them based on customer feedback.
Project 3: Implementing a Serverless Function with AWS Lambda
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Goal:
Create a simple AWS Lambda function that processes form input (e.g., a contact form) and stores it in DynamoDB.
Detailed Explanation
This chunk introduces the goal of implementing a serverless architecture using AWS Lambda. Serverless computing allows developers to write code without provisioning or managing servers. In this case, AWS Lambda will handle incoming form data and store it in DynamoDB, a NoSQL database service. This improves efficiency and scalability, as users only pay for the compute time they consume.
Examples & Analogies
Consider a digital assembly line where items are processed as they arrive without needing a dedicated workspace. AWS Lambda acts like a smart worker who starts processing forms as soon as they arrive, storing each form input in its respective location (DynamoDB).
Project 4: Setting Up a CI/CD Pipeline for Automated Deployments
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
Goal:
Set up a pipeline to automatically deploy code changes from GitHub to EC2 or S3.
Detailed Explanation
This chunk describes setting up a Continuous Integration/Continuous Deployment (CI/CD) pipeline. The goal is to automate the process of deploying code whenever changes are made in the GitHub repository. This reduces manual errors and speeds up the deployment process, allowing developers to focus on building better code rather than worrying about how to deploy it.
Examples & Analogies
Imagine an assembly line in a factory that automatically picks up new parts (code changes) and assembles them into a final product (website/application) without any manual intervention. This pipeline ensures that every new part goes through quality checks before being assembled, resulting in a better final product.
