Question
A company has 10 Amazon EC2 instances that run web server software in a production VPC. The company also has 10 web servers that run in an on- premises data center. The company has a 10 Gbps AWS Direct Connect connection between the on-premises data center and the production VPC. The data center uses the 10.100.0.0/20 CIDR block. The company needs to implement a load balancing solution that receives HTTPS traffic from thousands of external users. The solution must distribute the traffic across the web servers on AWS and the web servers in the data center. Regardless of the location of the web servers, HTTPS requests must go to the same web server for the duration of the session. Which solution will meet these requirements?

Explanation
Application Load Balancer (ALB) is the best choice for handling HTTPS traffic because it operates at the application layer (Layer 7). It supports features such as sticky sessions, which are required to ensure that requests from the same user are routed to the same server for the duration of the session. IP as the Target Type: To load balance traffic between both EC2 instances and on-premises servers, the target type must be set to IP. This configuration allows the ALB to distribute traffic to servers identified by IP addresses, including those in the on-premises data center. Sticky Sessions: Application-based sticky sessions ensure that the load balancer uses cookies to route requests consistently to the same web server, meeting the requirement for session
