  B) Eliminated - You need a second load balancer, which increases both costs and maintenance overhead. Testers must switch between different URLs to test the beta version, which is less seamless. C/D) Eliminated - Lambda@Edge increases complexity unnecessarily

  A ) New Beta Group: You create a new "group of servers" (Auto Scaling group + target group) for the beta version of your app. These servers will run the updated beta code. Routing with Cookies: The existing load balancer is updated to check incoming requests for a specific cookie in the browser. If the cookie says something like version=beta, the load balancer will route the request to the beta servers. If there’s no cookie, the load balancer routes the request to the normal servers (current version). Test System’s Role: The test system (used by testers) adds the special cookie (version=beta) to its requests. This ensures only the testers access the beta version. Regular users don’t have this cookie, so they continue to see the normal version.
