5 tasks

In this lab, you will learn how to configure a Virtual Private Cloud (VPC) with both public and private subnets. You will set up a NAT Gateway to enable instances in a private subnet to access the Internet securely. Additionally, you will configure security groups and network ACLs to enhance the security posture of your VPC. This exercise will reinforce best practices for network isolation and resource accessibility, vital for any associate-level AWS CloudOps professional. You will gain hands-on experience in configuring essential network components on AWS, helping you build a secure, compliant environment. The skills gained from this exercise are directly applicable to real-world scenarios where networking and security are paramount.
