Scenario: Your company wants to implement A/B testing for different versions of the website's homepage. How would you use Lambda@Edge to achieve this?
- Configure Lambda@Edge to intercept requests to the homepage and route them to different versions based on predefined rules, enabling A/B testing.
- Deploy Lambda@Edge to manage user sessions and track engagement metrics across different versions of the homepage, facilitating A/B testing analysis.
- Implement Lambda@Edge to generate personalized homepage content for each user based on historical interactions, enhancing A/B testing accuracy.
- Utilize Lambda@Edge to analyze user behavior and dynamically adjust the homepage content for A/B testing based on real-time feedback.
Configure Lambda@Edge to intercept requests to the homepage and route them to different versions based on predefined rules, enabling A/B testing.
Scenario: You need to restrict access to certain content based on the geographic location of the viewer. How can Lambda@Edge assist in implementing this functionality?
- Configure Lambda@Edge to compress content based on viewer location, optimizing delivery and reducing latency for restricted content.
- Deploy Lambda@Edge to authenticate viewers based on their geographic location and grant access to restricted content accordingly.
- Implement Lambda@Edge to evaluate viewer location using geolocation headers and block access to restricted content accordingly.
- Utilize Lambda@Edge to encrypt content based on viewer location, ensuring secure transmission of restricted data to authorized regions only.
Implement Lambda@Edge to evaluate viewer location using geolocation headers and block access to restricted content accordingly.
