AWS Cloud practice
Core AWS services — IAM, EC2, S3, VPC, Lambda
Build real fluency in Amazon Web Services — the cloud fundamentals and the core services, explained by what they do and when to reach for them. Start with the fundamentals: how the cloud works, Regions and Availability Zones, the shared-responsibility model, and pay-as-you-go pricing. Master identity with IAM (users, groups, roles, and policies, and least privilege), then the core building blocks: compute (EC2, serverless Lambda, containers, Auto Scaling, load balancers), storage (S3 object storage, EBS block volumes, EFS file storage, Glacier), networking (VPCs, public vs private subnets, security groups vs network ACLs, Route 53 DNS, CloudFront CDN), and databases (managed relational RDS vs NoSQL DynamoDB). Finish with operations: monitoring with CloudWatch and auditing with CloudTrail. Every question teaches the concept and names the classic mix-up (security group vs NACL, S3 vs EBS, IAM role vs user, EC2 vs Lambda). Grounded in the official AWS docs and aligned to the concepts in the Cloud Practitioner and Solutions Architect Associate certifications — using original questions, never real exam items. Part of the Developer track. Educational only — general cloud concepts, not architecture or security advice for a specific system.
