What it covers

Security & Identity

Learn IAM and the shared responsibility model to enforce least privilege across accounts. Identity is the primary security perimeter in the cloud.

IAM users, roles, and policiesPolicy evaluation and least privilegeRoles for cross-account and service accessMFA and credential rotationEncryption with KMS and Secrets Manager

Data Protection

Protect data at rest and in transit, and plan for recovery before something goes wrong. Losing a key or an unrecoverable backup is often worse than the outage that caused it.

Resilience & HA

Design systems that keep running when an instance, an AZ, or a whole region fails. Availability is an architecture decision made up front, not a fix applied after an outage.

Well-Architected reliability pillarMulti-AZ deployments and automated failoverMulti-region architectures, RTO, and RPORoute 53 health checks and DNS failoverAuto Scaling and self-healing infrastructure

Decoupling & Integration

Connect services with queues, events, and workflows instead of direct calls. Loosely coupled systems scale independently and keep working when one part slows down or fails.

SQS queues for asynchronous processingSNS pub/sub and fan-out patternsEventBridge for event-driven architecturesStep Functions for workflow orchestrationAPI Gateway for service-to-service integration

Compute

Understand AWS compute options from VMs to serverless so you can pick the right runtime for each workload. Compute choice drives cost, scaling, and operational burden.

EC2 instance types and lifecycleAuto Scaling Groups and load balancersLambda and event-driven computeContainers: ECS vs. EKS vs. FargateSpot, Reserved, and On-Demand pricing

Storage

Learn the AWS storage services and when to use object, block, or file storage. Matching storage to access patterns optimizes durability, latency, and cost.

S3 storage classes and lifecycle policiesEBS volume types and snapshotsEFS shared file storageS3 durability, versioning, and encryptionGlacier and archival tradeoffs

Databases

Understand the managed database options so you can match data models to the right engine. Picking the correct database avoids costly re-architecture later.

RDS engines and Multi-AZ failoverAurora architecture and read replicasDynamoDB partition keys and capacity modesCaching with ElastiCacheBackups, snapshots, and point-in-time recovery

Networking & Content Delivery

Master VPC design and connectivity so resources are isolated, routable, and secure. Networking is the foundation every AWS architecture is built on.

VPC, subnets, and CIDR planningRoute tables, IGW, and NAT gatewaysSecurity groups vs. NACLsVPC peering and Transit GatewayRoute 53 DNS and load balancers
