Create a Highly Available VPC

You work for a managed service provider, and your team has just received a request from a new client. In the initial request, the client has asked you to create a highly available VPC that contains two public and two private subnets. The client has also requested a security group named PublicSG that will be used to permit HTTPS traffic, as well as a second security group named PrivateSG permitting all traffic from PublicSG. For additional security and monitoring, the client would also like to send VPC flow logs to S3 to monitor all incoming and outgoing traffic.
