Deconstructing the Cloud

I. Global Infrastructure Regions: 32+ (big geographic areas, e.g., us-east-1) Availability Zones (AZs): 100+ (isolated data centers inside regions) Local Zones: Extend regions closer to users Wavelength Zones: 5G edge computing Outposts: AWS hardware in your data center Edge Locations: 400+ for CloudFront/Lambda@Edge Network Backbone: Private, redundant 100+ Gbps fiber; Direct Connect for private links II. Compute EC2: Virtual servers Instance families: General (M), Compute (C), Memory (R), GPU/Accelerated (P/Inf/Trn), Storage (I/D) Nitro System: Hardware-accelerated virtualization Placement groups: Cluster, Spread, Partition Spot, Reserved, On-Demand pricing Containers: EKS: Managed Kubernetes ECS: AWS-native container orchestration ECR: Container registry App Runner: Deploy containers easily Serverless: Lambda: Functions (10GB RAM, 15-min max) Step Functions: Workflows III. Storage Block: EBS (gp3, io2, snapshots), Instance Store (ephemeral) File: EFS (shared file system), FSx (Windows, Lustre, NetApp, ZFS) Object: S3 (Standard → Glacier Deep Archive, versioning, lifecycle, replication) Hybrid/Edge: Storage Gateway, Snowball/Snowmobile IV. Databases Relational: RDS (Aurora, MySQL, PostgreSQL, Oracle, SQL Server, MariaDB) Data Warehouse: Redshift NoSQL: DynamoDB (auto-scaling, global tables, streams) Specialized: ElastiCache (Redis/Memcached), Neptune (graph), Timestream (time-series), QLDB (ledger) V. Networking & Delivery VPC: CIDR, subnets, route tables, IGW, NAT, SGs (stateful), NACLs (stateless) Advanced: Transit Gateway, VPC Peering, PrivateLink, Direct Connect DNS: Route 53 (latency, geo, weighted routing) CDN: CloudFront (225+ PoPs, Lambda@Edge) VI. Security & Compliance IAM: Users, Roles, Policies, Permission Boundaries Advanced: Organizations, GuardDuty, Inspector, Macie, WAF/Shield Encryption: KMS, CloudHSM, Secrets Manager Compliance: 143+ certifications, Artifact, Config VII. Monitoring & Management CloudWatch: Metrics, Logs, Alarms, Dashboards X-Ray: Tracing OpenSearch: Log analytics CloudFormation/CDK: Infrastructure as Code Systems Manager: Parameters, Patch, Automation Control Tower: Multi-account governance VIII. Migration & Modernization Migration Hub: Track migrations DMS: Database migration SMS: Server migration DataSync: Data transfer Mainframe Modernization: Refactor legacy apps IX. AI/ML SageMaker: Build/train/deploy ML Bedrock: Foundation models (Claude, Llama, Titan) Rekognition: Image/video Comprehend: NLP Forecast/Personalize: Predictions & recommendations X. Integration & Messaging EventBridge: Event bus SNS: Pub/Sub SQS: Queues Kinesis: Streaming data API Gateway: REST/HTTP/WebSocket APIs AppSync: GraphQL APIs XI. Cost Optimization Pricing Models: On-Demand, Reserved, Savings Plans, Spot Tools: Cost Explorer, Budgets, Trusted Advisor, Compute Optimizer XII. Well-Architected Pillars Operational Excellence: Automation, CI/CD Security: Zero-trust Reliability: Multi-AZ, failover Performance Efficiency: Right-sizing, caching Cost Optimization: Rightsizing, pricing models Sustainability: Energy-efficient workloads XIII. Real-World Patterns Multi-Tier Apps: ALB → ECS/EKS → RDS Data Lakes: S3 + Glue + Athena Event-Driven Microservices: API Gateway → Lambda → DynamoDB → EventBridge Hybrid: Direct Connect + Transit Gateway XIV. Ops Best Practices DevOps: CodePipeline, CodeBuild, CodeDeploy IaC: CloudFormation/CDK/Terraform Disaster Recovery: Backup, Pilot Light, Warm Standby, Active/Active High Availability: Multi-AZ, Route 53 failover XV. Emerging Trends Generative AI (Bedrock, SageMaker JumpStart) Sustainability (Carbon Footprint tool) Industry solutions (HealthLake, FinSpace) Quantum (Braket) 5G Edge (Wavelength, Private 5G) XVI.
