+A single EC2 instance hosts both Kill Bill and Kaui servers in the VPC, running on an Ubuntu Linux server. AWS autoscaling is utilized to dynamically adjust the number of instances for each package based on demand, allowing for efficient scaling.
 
 Access to these instances is managed by an AWS *Elastic Load Balancer (ELB)*. The ELB routes each request to the correct package and distributes the requests across the available instances. The ELB accepts traffic securely using HTTPS by default.
