Setting Up a Basic Web Server on AWS
introduction to AWS EC2
Amazon Elastic Compute Cloud (EC2) is a foundational service in AWS , providing virtual servers in the cloud. It allows you to run applications on a variety of operating systems , offering scalable computing capacity. Understanding EC2 is crucial for anyone looking to deploy applications in the cloud.
Step-by-Step Guide to Launching an EC2 Instance
1. Sign Up for AWS: If you don’t already have an AWS account , sign up at the AWS Management Console. You’ll need to offer a credit card , but you can use the complimentary tier for this project.
2. Navigate to EC2: Once logged in , go to the EC2 dashboard. This is where you’ll manage your virtual servers.
3. Launch an Instance: Click on “Launch Instance” to start the process of creating a new virtual server. You’ll be presented with a variety of Amazon Machine Images (AMIs) , which are pre-configured operating systems and software stacks.
4. select an AMI: select an AMI that suits your needs. For a basic web server , an Ubuntu or Amazon Linux AMI is a good choice. Make sure to select an AMI that is eligible for the complimentary tier if you want to avoid charges.
5. select Instance Type: select an instance type. The t2.micro instance is complimentary tier eligible and suitable for this project. Instance types determine the amount of CPU , memory , and network performance available to your instance.
6. Configure Instance Details: Configure the instance details , such as the number of instances , network settings , and IAM function. For a basic setup , you can leave most of these settings at their defaults.
7. Add Storage: Add storage to your instance. The default is usually 8GB , which is sufficient for a basic web server. You can boost this if you plan to host more text.
8. Add Tags: Add tags to your instance. Tags are key-value pairs that help you organize and manage your resources. For example , you can add a tag with the key “Name” and the value “MyWebServer”.
9. Configure Security Group: Configure a security group. Security groups act as virtual firewalls , controlling the traffic that is allowed to and from your instance. You’ll need to allow inbound traffic on port 80 (HTTP) and port 22 (SSH). Optionally , you can also allow inbound traffic on port 443 (HTTPS).
10. Review and Launch: Review your configuration and launch the instance. You’ll be prompted to create or select an existing key pair. A key pair is used to securely connect to your instance via SSH. Download the key pair and keep it in a safe place.
11. Connect to Your Instance: Once the instance is running , connect to it via SSH using the key pair you downloaded. You’ll need an SSH client , such as PuTTY on Windows or the built-in SSH client on macOS and Linux.
Installing and Configuring a Web Server (e.g. , Apache)
1. Update Package Lists: After connecting to your instance , update the package lists using the following command:
sudo apt update
2. Install Apache: Install the Apache web server using the following command:
sudo apt install apache2
3. Start Apache: Start the Apache web server using the following command:
sudo systemctl start apache2
4. Enable Apache: Enable Apache to start automatically on boot using the following command:
sudo systemctl enable apache2
5. Test Your Web Server: Open a web browser and navigate to the public IP address of your EC2 instance. You should see the default Apache welcome page.
Securing Your Web Server
1. Enable HTTPS: Enable HTTPS by installing an SSL certificate. You can use Let’s Encrypt , a complimentary and open-source certificate authority , to obtain a certificate.
2. Configure Firewall: Configure your firewall to only allow traffic on ports 80 and 443. You can use the ufw firewall on Ubuntu to do this.
3. Regular Updates: Keep your operating system and software up to date by installing security patches regularly.
Monitoring Your Web Server
1. AWS CloudWatch: Use AWS CloudWatch to monitor the performance of your web server. CloudWatch offers metrics , logs , and alarms to help you keep track of your resources.
2. Logging: Configure logging to track requests and errors. Analyze your logs regularly to determine potential issues.
Example: Hosting a Static Website
1. Create an HTML File: Create an HTML file with your website text. For example , you can create a file named index.html with the following text:
html
My Website
Welcome to my website!
This is a simple website hosted on AWS EC2.
2. Copy the File to the Web Server: Copy the HTML file to the web server’s document root , which is usually /var/www/html on Ubuntu. You can use the scp command to do this:
scp -i your-key-pair.pem index.html ubuntu@your-ec2-instance-public-ip:/var/www/html/
3. Test Your Website: Open a web browser and navigate to the public IP address of your EC2 instance. You should see your website text.
By following these steps , you can set up a basic web server on AWS and gain hands-on experience with cloud computing. This project offers a foundation for more advanced cloud deployments and helps you understand the core ideas of cloud infrastructure.

7. Integrate with Lambda: Integrate your API method with your Lambda function. This tells API Gateway to invoke your Lambda function when the API method is called.
Testing Your Serverless Application
1. Deploy Your API: Deploy your API to make it accessible to the public.
2. Test Your API Endpoint: Test your API endpoint by sending a request to it. You can use a tool like Postman to send requests to your API.
Example: Building a Simple API to Return a Greeting

python
import json def lambda_handler(event, context):
return {
'statusCode': 200,
'body': json.dumps('Hello from Lambda!')
}
2. Create an API Gateway Endpoint: Create an API Gateway endpoint that triggers the Lambda function.
3. Test the API: Test the API by sending a GET request to the endpoint. You should receive a response with the greeting.
benefits of Serverless Computing
1. Reduced Operational Overhead: Serverless computing eliminates the need to manage servers , reducing operational overhead.
2. Scalability: Serverless applications automatically scale to handle varying levels of traffic.
3. Cost Savings: You only pay for the compute time you consume , which can outcome in significant cost savings.
