A startup software company has several application teams that develop API services for its business. Each application team is responsible for services separated on different AWS accounts. The VPC of each AWS account was initially provisioned with a 192.168.0.0/24 CIDR block. The services are deployed on Amazon EC2 instances accessed on a secure HTTPS public endpoint of an Application Load Balancer. Integration between the services routes externally to the public internet. As part of security audit, there is a recommendation from the security team to re-architect the integration between services to communicate on HTTPS on the private network only. A solutions architect is asked to suggest a long-term solution considering the possibility of adding more VPCs in the future. What should the solutions architect recommend?
