Mastering Cloud Architecture with AWS

Cloud architecture is the backbone of modern applications. In this guide, we'll explore best practices for building scalable systems on AWS.

Core Principles

1. Design for Failure

Everything fails eventually. Design your systems to handle failures gracefully:

• Use multiple Availability Zones
• Implement health checks
• Set up auto-scaling groups

2. Decouple Components

Loose coupling allows components to scale independently:

// Use message queues for async communication
import { SQS } from 'aws-sdk';

const sqs = new SQS();
await sqs.sendMessage({
  QueueUrl: process.env.QUEUE_URL,
  MessageBody: JSON.stringify(data)
}).promise();

Key AWS Services

• EC2: Virtual servers
• Lambda: Serverless compute
• S3: Object storage
• RDS: Managed databases
• CloudFront: CDN

Conclusion

Building resilient cloud architecture requires careful planning and understanding of cloud-native patterns. Start small and iterate.
