🚀 Key AWS Services

Compute

  • EC2 - Virtual machines in the cloud
  • Lambda - Serverless computing
  • Elastic Beanstalk - Managed application hosting

Storage

  • S3 - Object storage
  • EBS - Block storage for EC2
  • EFS - Shared file system
  • Glacier - Long-term archival

Networking

  • VPC - Virtual private network
  • ALB/ELB - Load balancers
  • CloudFront - Content delivery network
  • Route 53 - DNS service

Databases

  • RDS - Relational databases
  • DynamoDB - NoSQL database
  • ElastiCache - Caching

Monitoring & Management

  • CloudWatch - Monitoring and logging
  • CloudTrail - Audit logging
  • Systems Manager - Resource management

💡 Key Concepts

Architecture Patterns

  1. Tier Architecture
    • Single-tier: All on one server
    • Two-tier: Presentation + Database
    • Three-tier: Front + App + Database
    • N-tier: Microservices

Deployment Strategies

  1. Blue-Green Deployment - Swap between versions
  2. Canary Deployment - Gradual rollout
  3. Rolling Deployment - Incrementally replace instances

Auto-Scaling

Metrics:
  - CPU Usage
  - Network Traffic
  - Custom Metrics

Actions:
  - Scale Up: Add more instances
  - Scale Down: Remove instances

Security

  • Security Groups - Firewall rules
  • IAM Roles - Permission management
  • VPC - Network isolation
  • Encryption - Data protection
