🎉Introduction

Welcome back to the 90 Days of DevOps Challenge!🌟

Today, we are diving deep into Amazon Web Services (AWS) to test our knowledge and skills on various AWS services.

Whether you're a seasoned AWS pro or just starting your journey into cloud computing, these tasks will provide valuable hands-on experience and insights into AWS services.

📜Task-01: Deploy, Monitor, and Troubleshoot a Web Server on AWS EC2

Launching an EC2 Instance

  1. Accessing the AWS Management Console: The first step is to log in to your AWS Management Console.

  2. Navigating to EC2 Service: Go to the EC2 service within the console.

  3. Launching a New EC2 Instance: Similar to what we've discussed in our previous blogs, launch a new EC2 instance. Opt for the free tier t2 micro to stay within the free usage limits.

  4. Configuring Instance Details: Configure essential details, such as instance type, Virtual Private Cloud (VPC), subnet, and security group settings.

  5. Setting Up SSH Access: Create a new key pair or use an existing one to enable SSH access to the instance.

  6. Launching the Instance: Finally, launch the instance.

Connecting to the EC2 Instance

  1. Once the instance is up and running, connect to it using SSH from your local machine.

Installing a Web Server

  1. Updating Package Manager: On the EC2 instance, update the package manager using the command

     sudo apt update -y

  2. Installing Apache Web Server: Install the Apache Web Server on the EC2 instance with the command

     sudo apt install apache2 -y

Deploying a Simple Web Application

  1. Editing index.html: Use an editor like vi or nano to edit the index.html file.

  2. Inserting Web Page Code: Insert your basic HTML and CSS code to create the content of your web page.

Monitoring EC2 Instance with Amazon CloudWatch

  1. Accessing AWS CloudWatch: Go to the AWS CloudWatch service in the AWS Management Console.

  2. Creating an Alarm: Click on "Create alarm" and select the EC2 metric you want to monitor, e.g. CPU utilization

  3. Configuring Conditions: Set up alarm conditions and notification settings as needed.

  4. Creating the Alarm: Give your alarm a name and create the alarm. This will trigger alerts based on the conditions you've set.

📃Task-02: Auto Scaling and Monitoring with AWS Console and CLI

Creating an Auto Scaling Group (ASG)

  1. Log In and Navigate: Log in to your AWS Management Console and navigate to the Auto Scaling service.

  2. Create a New ASG: Create a new Auto Scaling group and configure the launch template or instance configuration.

  3. Set Scaling Policies: Define your scaling policies, specifying minimum and maximum instances.

  4. Desired Capacity: Set the desired capacity, minimum, and maximum capacity for your ASG.

  5. Review and Create: Review your configuration and create the Auto Scaling group.

Monitoring ASG and EC2 Instances with Amazon CloudWatch

You can monitor your ASG and EC2 instances by adding them to an AWS CloudWatch dashboard or setting up CloudWatch alarms to trigger notifications.

Verifying ASG State Using AWS CLI

  1. Install and Configure AWS CLI: Install and configure the AWS CLI on your local machine, providing your Access Key ID, Secret Access Key, Region Name, and Output Format.

  2. View ASG Information: Use AWS CLI commands to view information about the Auto Scaling group and its instances.
