What is Cloud Computing?
Cloud computing, exemplified by Amazon Web Services (AWS), provides scalable, on-demand computing resources over the internet. This article introduces AWS and guides you through launching a simple web server on EC2.
1. Setting Up an AWS Account
Create an AWS account and access the AWS Management Console. Set up billing and IAM roles for secure access.
2. Launching an EC2 Instance
In the EC2 dashboard, launch an instance using the Amazon Linux AMI. Configure instance type (e.g., t2.micro) and a key pair for SSH access.
3. Installing a Web Server
SSH into your instance and install Apache:
sudo yum update -y sudo yum install httpd -y sudo systemctl start httpd
Create a simple HTML file in /var/www/html and access it via the instance’s public IP.
4. Configuring Security Groups
Update security groups to allow HTTP (port 80) and SSH (port 22) traffic, ensuring your web server is accessible.
Conclusion
AWS offers powerful tools like EC2, S3, and RDS for building scalable applications. Start with free-tier services, monitor usage to manage costs, and explore AWS documentation to leverage services like Lambda or ECS for advanced deployments.
