Format: Video demo + knowledge check. No hands-on in module.
Key Concepts Takeaways:
- EC2 = Virtual servers. t2.micro = Free Tier eligible
- Pricing models: On-Demand for unknown traffic, Spot for batch jobs 90% off, Savings Plans 72% off for 1-3yr commit
- Auto Scaling + ELB = elasticity + high availability
- Exam traps: "Critical" never uses Spot. "Unsure/flexible" = On-Demand
Extra Credit: Found "Builder Labs: Introduction to AWS Cloud" for hands-on EC2. Completed pricing knowledge checks on Savings Plans vs Spot.
Next: Builder Lab 1 for actual EC2 hands-on. Assessment Result: https://github.com/selfman01-cloud/Cloud-Parctitioner-Notes/blob/main/IMG_2089.jpeg?raw=true

What is VPC? A logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network you define.
Key Components:
- Subnet: Range of IP addresses in your VPC. Split into Public and Private.
- Internet Gateway (IGW): Allows communication between your VPC and the internet.
- Route Table: Controls where network traffic is directed.
- Security Group: Acts as a firewall for EC2 instances. Stateful.
- Network ACL: Acts as a firewall for subnets. Stateless.
- NAT Gateway: Allows private subnet instances to access the internet outbound.
Key for CLF-C02 Exam:
- VPC = your virtual data center in AWS
- Public subnet has a route to IGW, Private subnet does not
- Security Groups vs NACLs is a common exam question
