Cloud computing has revolutionized how we deploy and scale applications. Here's a beginner-friendly guide to getting started with AWS.
Start with the basics: EC2 for compute, S3 for storage, and RDS for databases. These three services cover most common use cases and are well-documented.
Infrastructure as Code (IaC) is essential for reproducible deployments. Tools like Terraform or AWS CloudFormation let you define your infrastructure in version-controlled files.
Security is paramount. Use IAM roles and policies to implement the principle of least privilege. Never hardcode credentials in your application code.
Cost management is often overlooked. Set up billing alerts, use reserved instances for predictable workloads, and regularly review your resource usage.
