AWS Certified Solution Architect an Overview - Part 1
summary
Overview of practical AWS patterns: DNS via Route 53 to VPCs with public/private subnets, ELB, CloudFront fronting S3 and origin servers, session caching in DynamoDB or ElastiCache, read replicas and multi‑AZ RDS, EBS vs EFS for storage, Lambda for event jobs, SQS for queuing, autoscaling and DB sharding for growth to millions. Gives concrete thresholds — 250 ms as responsiveness goal and 500 ms as user impatience cutoff — and recommends evolutionary architecture and cache + CDN patterns that scale from 100 users to 500k and beyond.
