Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 190 discussion

A company has a web application that is based on Java and PHP. The company plans to move the application from on premises to AWS. The company needs the ability to test new site features frequently. The company also needs a highly available and managed solution that requires minimum operational overhead.

Which solution will meet these requirements?

  • A. Create an Amazon S3 bucket. Enable static web hosting on the S3 bucket. Upload the static content to the S3 bucket. Use AWS Lambda to process all dynamic content.
  • B. Deploy the web application to an AWS Elastic Beanstalk environment. Use URL swapping to switch between multiple Elastic Beanstalk environments for feature testing.
  • C. Deploy the web application to Amazon EC2 instances that are configured with Java and PHP. Use Auto Scaling groups and an Application Load Balancer to manage the website‚Äôs availability.
  • D. Containerize the web application. Deploy the web application to Amazon EC2 instances. Use the AWS Load Balancer Controller to dynamically route traffic between containers that contain the new site features for testing.

The correct answer is D. AWS Elastic Beanstalk is a service that makes it easy to deploy and manage web applications in the AWS cloud. However, it is not a good solution for testing new site features frequently, as it can be difficult to switch between multiple Elastic Beanstalk environments.

Selected Answer: B
B. Provides a highly available and managed solution with minimum operational overhead. By deploying the web application to EBS, the infrastructure and platform management are abstracted, allowing easy deployment and scalability. With URL swapping, different environments can be created for testing new site features, and traffic can be routed between these environments without any downtime. A. Suggests using S3 for static content hosting and Lambda for dynamic content. While it offers simplicity for static content, it does not provide the necessary flexibility and dynamic functionality required by a Java and PHP-based web application. C. Involves manual management of EC2, ASG, and ELB, which requires more operational overhead and may not provide the desired level of availability and ease of testing. D. Introduces containerization, which adds complexity and operational overhead for managing containers and infrastructure, making it less suitable for a requirement of minimum operational overhead.

Containers allow you test your app in isolated environments, therefore D is the correct option.

B - Because AWS Elastic Beanstalk performs an in-place update when you update your application versions, your application might become unavailable to users for a short period of time. To avoid this, perform a blue/green deployment. To do this, deploy the new version to a separate environment, and then swap the CNAMEs of the two environments to redirect traffic to the new version instantly.

A and C are not allowing for feature testing. B and D allow feature testing. D requires overhead of containerisation as well as the LB controller to selectively chose containers for features (assuming on how this might be implemented). EBS allows switching between environment like A/B testing but on whole site. Expensive but cost is not a concern for this question.

Selected Answer: D
WS Elastic Beanstalk supports multiple environments, but each environment can only run one platform at a time. A platform is a combination of an operating system, runtime, and web server, and in this case, Java and PHP would be considered different platforms. So, if you want to use both Java and PHP, you would need to create two separate environments, one for each. You can then link these environments together using AWS services like Route 53 for routing traffic, or use an Application Load Balancer to distribute incoming traffic between the two environments.

Selected Answer: B
Option B (AWS Elastic Beanstalk): Elastic Beanstalk is a fully managed service that makes it easy to deploy and run applications in multiple languages (including Java and PHP) with MINIMAL OPERATION OVERHEAD. It abstracts the infrastructure management, allowing you to focus on your application. URL swapping in Elastic Beanstalk allows you to easily switch between different environments, making it convenient for testing new features.

Selected Answer: B
B is the correct answer. Using AWS Elastic Beanstalk provides a fully managed platform to deploy the web application. Elastic Beanstalk will handle provisioning EC2 instances, load balancing, auto scaling, and application health monitoring. Elastic Beanstalk's ability to support multiple environments and swap URLs allows easy testing of new features before swapping into production. This requires minimal overhead compared to managing infrastructure directly.

Frequent feature testing - - Multiple Elastic Beanstalk environments can be created easily for development, testing and production use cases. - Traffic can be routed between environments for A/B testing and feature iteration using simple URL swapping techniques. No complex routing rules or infrastructure changes required.
