Eleven modules
Each module explains what is covered, why it matters, and ends with a five-question quiz drawn at random from that module’s question bank. Nothing here is isolated — networking explains VPC, Linux explains EC2, IAM explains everything.
🌐 Networking & the OSI Model
How data actually travels: seven layers, cables and radio waves, MAC and IP, hubs, switches, routers and WAN links.
🔢 IP Addressing & Subnetting
Binary, dotted decimal, subnet masks, CIDR, and how to cut one network into many using fixed and variable length masks.
🐧 Linux Fundamentals
The operating system every cloud server runs. Commands, the file tree, pipes and filters, and the permission model.
☁ Cloud Concepts & AWS Billing
What the cloud actually changes, the six advantages, how AWS charges you, and how to keep a bill under control.
🔒 Global Infrastructure, IAM & Security
Regions, Availability Zones and edge locations; who secures what; and how identity and access management works.
🗺 Amazon VPC & Networking
Your own private network inside AWS: subnets, route tables, gateways, security groups and network ACLs.
🗃 DynamoDB, Redshift, CloudFront & Route 53
A NoSQL database, a data warehouse, a content delivery network and DNS — four services, four different jobs.
🏛 Well-Architected Framework & Trusted Advisor
The six pillars AWS uses to judge an architecture, and the tool that checks your account against them.
📈 CloudWatch & SNS
Monitoring that tells you something is wrong, and notifications that make sure a human finds out.
🛡 Security Components, GuardDuty, Inspector & WAF
Preventive, detective and responsive controls — and the three services that do the detecting and the blocking.
🎓 Project, Labs & Interview Preparation
Turning eleven modules into something you can show an interviewer — including the course project website itself.
Labs and reference pages
🖩 S3 Static Website Lab
Host a website on Amazon S3 with the AWS CLI, line by line — including what each bucket policy field means and how to troubleshoot a 403.
🦅 OSI Encapsulation Walkthrough
One HTTPS request followed all the way down through all seven OSI layers and back up again.
⚡ AWS Services Cheat Sheet
Every AWS service in the course on a single page, plus the port numbers and key figures worth remembering.
📖 Glossary
150+ terms from across the whole course, each explained in one plain sentence.

Engineers new to cloud
Developers, DBAs and sysadmins who need the fundamentals under the AWS services rather than a list of product names.
Students and career changers
Anyone working toward an entry-level cloud role who wants something buildable to show an interviewer at the end.
Teams preparing for certification
Useful groundwork ahead of AWS Certified Cloud Practitioner or Solutions Architect – Associate study.
