- Professionals pursuing AWS certifications (SAA/SAP)
- Teams planning migrations from on-premises to the cloud
Prerequisites
- Basic Linux operations
- Networking fundamentals (TCP/IP, DNS, HTTP)
- Basic container knowledge (Docker)

Quick Reference
AWS Service Selection Chart:
Compute:
Containers → ECS Fargate (recommended) or EKS
Serverless → Lambda + API Gateway
VMs → EC2 + Auto Scaling
PaaS → Elastic Beanstalk
Database:
Relational → Aurora (recommended) or RDS
NoSQL → DynamoDB
Cache → ElastiCache Redis
Full-text search → OpenSearch
Storage:
Object → S3
File → EFS
Block → EBS
Networking:
DNS → Route 53
CDN → CloudFront
Load Balancer → ALB
Cost Reduction:
✓ Savings Plans / Reserved Instances
✓ Spot Instances (for fault-tolerant workloads)
✓ S3 Lifecycle policies (transition to Glacier)
✓ Lambda (for low-traffic periods)
