AWS Virtual Private Clouds (VPCs) provide isolated, secure networking environments within AWS, ensuring customer resources are isolated from others and allowing full control over IP addressing, routing, and security. 1:11
Key Takeaways:
• VPCs isolate resources from other customers and allow customers to create multiple VPCs for segmentation (e.g., dev, staging, production) 2:35
• Each VPC is tied to a specific region and includes a CIDR block defining its IP address range, which must be between /16 and /28 8:30
• Subnets are IP ranges within a VPC, reside in a single availability zone, and can be configured as public or private 6:00
• Public subnets have internet access via an internet gateway; private subnets require a NAT gateway (for outbound only) or VPN for secure access 12:00
• VPN gateways provide encrypted internet access to private resources; Direct Connect offers a high-speed, low-latency physical connection to AWS 14:30
VPCs are essential for secure, flexible AWS networking, enabling organizations to design isolated, scalable, and controlled cloud environments.

[Music] Hey there, I'm Michael from CodeCloud. Welcome to this lesson from our AWS cloud practitioner certification course. In this video, we'll help you build a strong foundation in cloud computing with AWS. So, if you want to learn more or go deeper, check out the full course details below and let's get started. In this lecture, we're going to talk about networking within AWS. So, when we went over the basics of AWS, we learned that when we deploy our application onto AWS, it's going to be running on the same exact infrastructure that all of the other customer applications are running on. So, our application is running on the same exact infrastructure that everyone else's applications are running on. Now, does that mean that all of the other customers that use AWS could potentially commu…
