Quick Overview

This section outlines the practical steps required for several real-world AWS projects.

Standard

In this section, we explore practical and detailed steps to successfully deploy various AWS projects, including hosting static websites and deploying web apps, while illustrating the use of various AWS services.

Detailed

Steps

This section details the hands-on procedures for several real-world AWS projects that help transition theoretical knowledge into practical skills. Each project focuses on different AWS services and culminates in real-world applications:

1. Hosting a Static Website on Amazon S3:
- The steps include preparing website files, creating an S3 bucket, uploading files, enabling static website hosting, setting permissions, and accessing the website.

2. Deploying a Web Application Using EC2 and RDS:
- This project covers creating an RDS instance for MySQL, launching an EC2 instance, installing necessary software, deploying an application code, and testing the setup.

3. Implementing a Serverless Function with AWS Lambda:
- Steps include creating a DynamoDB table, developing a Lambda function to process submissions, and setting up an API Gateway for triggering the Lambda function.

4. Setting Up a CI/CD Pipeline for Automated Deployments:
- The final project involves preparing a GitHub code repository, creating a CodePipeline, deploying it to S3 or EC2, and testing the setup.

These projects build confidence and skill in using AWS services, preparing users to manage real-world applications in the cloud.

Chunk 1: Prepare Your Website Files

Unlock Audio Book

Signup and Enroll to the course for listening the Audio Book

  1. Prepare your website files:
  2. Create an index.html and error.html page.

Detailed Explanation

The first step in hosting a static website on Amazon S3 is to prepare your files. This involves creating two essential HTML files called index.html and error.html. The index.html file is the main page that users will see when they access the website, while the error.html file will be displayed if there are any issues, such as a broken link.

Examples & Analogies

Think of your website as a book. The index.html is like the cover page that introduces readers to the content, while the error.html acts as a 'sorry, this page is not available' message, similar to having a warning sign in a library.

Chunk 2: Log in and Go to S3 Dashboard

Unlock Audio Book

  1. Login to AWS Console and go to the S3 Dashboard.

Detailed Explanation

Once your website files are prepared, the next step is to access the AWS Management Console. You will log in to your AWS account and navigate to the S3 (Simple Storage Service) Dashboard, where you will manage your storage buckets and uploaded files.

Examples & Analogies

Imagine entering a large warehouse where you store all your items (your website files). The S3 Dashboard acts as your control room, where you can see and manage everything you have stored.

Chunk 3: Create a New Bucket

Unlock Audio Book

Signup and Enroll to the course for listening the Audio Book

  1. Create a new bucket:
  2. Bucket name must be globally unique.
  3. Disable 'Block all public access' under Permissions.

Detailed Explanation

Creating a new bucket is crucial for storing your files. A bucket in S3 is like a folder in your file cabinet. When creating it, you must give it a name that is unique across all AWS users. Additionally, to make your website accessible to everyone, you must disable the 'Block all public access' setting, allowing public visibility of the files in that bucket.

Examples & Analogies

Think of your bucket as a public library. You need a unique name for the library that does not exist anywhere else, and to let people in, you need to take down any 'no entry' signs.

Chunk 4: Upload Website Files

Unlock Audio Book

  1. Upload website files to the bucket.

Detailed Explanation

Now that your bucket is created, the next step is to upload your prepared website files (index.html and error.html) into the bucket. This step brings your website content into the storage space you just created.

Examples & Analogies

This can be compared to filling your library with books. You gather your carefully prepared books (website files) and place them onto the shelves of your library (the bucket).

Chunk 5: Enable Static Website Hosting

Unlock Audio Book

Signup and Enroll to the course for listening the Audio Book

  1. Enable static website hosting:
  2. Go to the bucket's Properties tab.
  3. Enable Static website hosting and set index/error documents.

Detailed Explanation

With your files uploaded, you need to enable static website hosting in the bucket's settings. This involves navigating to the Properties tab of your bucket and selecting the static website hosting option. Here, you’ll specify which files to use for index and error documents so that S3 knows how to handle incoming requests.

Examples & Analogies

Imagine you set up a website like opening the front door of your library for visitors. By enabling static website hosting, you are essentially creating a front desk that tells visitors what to look for (index.html) and what to do if they can’t find it (error.html).

Chunk 6: Set Bucket Policy for Public Access

Unlock Audio Book

Signup and Enroll to the course for listening the Audio Book

  1. 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 ensure that everyone can access your website, you need to set a bucket policy that allows public access. This involves editing the bucket policy JSON to permit 'GetObject' actions for all users so they can read the files in your bucket.

Examples & Analogies

It’s as if you decided to keep your library open to everyone. By providing an open-door policy (bucket policy), you let anyone walk in and read the books (files) without restriction.

Chunk 7: Access Your Website

Unlock Audio Book

Signup and Enroll to the course for listening the Audio Book

  1. Access your website using the S3 website endpoint.

Detailed Explanation

Finally, with everything set up, you can access your website. S3 provides a unique URL called the website endpoint where users can reach your site and view your content online.

Examples & Analogies

This step is like opening the library to the public with a sign outside that tells them where to enter and find the books. The endpoint serves as the library's address, leading people straight to your online resources.
