Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 481 discussion

A company's web application has reliability issues. The application serves customers globally. The application runs on a single Amazon EC2 instance and performs read-intensive operations on an Amazon RDS for MySQL database.

During high load, the application becomes unresponsive and requires a manual restart of the EC2 instance. A solutions architect must improve the application's reliability.

Which solution will meet this requirement with the LEAST development effort?

  • A. Create an Amazon CloudFront distribution. Specify the EC2 instance as the distribution’s origin. Configure a Multi-AZ deployment for the RDS for MySQL database. Use the standby DB instance for the read-intensive operations.
  • B. Run the application on EC2 instances that are in an Auto Scaling group. Place the EC2 instances behind an Elastic Load Balancing (ELB) load balancer. Replace the database service with Amazon Aurora. Use Aurora Replicas for the read-intensive operations.
  • C. Deploy AWS Global Accelerator. Configure a Multi-AZ deployment for the RDS for MySQL database. Use the standby DB instance for the read-intensive operations.
  • D. Migrate the application to AWS Lambda functions. Create read replicas for the RDS for MySQL database. Use the read replicas for the read-intensive operations.

D. Migrate the application to AWS Lambda functions. Create read replicas for the RDS for MySQL database. Use the read replicas for the read-intensive operations. Here's why the other options require more development effort: A. CloudFront with Multi-AZ RDS: This requires setting up CloudFront and configuring it to point to the EC2 instance. It also requires switching to a Multi-AZ RDS deployment, which might involve downtime. B. Auto Scaling with ELB and Aurora: This requires the most effort. You need to migrate the application to run on multiple EC2 instances managed by Auto Scaling, set up an ELB to distribute traffic, migrate the database to Aurora, and configure Aurora Replicas. C. Global Accelerator with Multi-AZ RDS: Similar to option A, this involves setting up Global Accelerator and requires a Multi-AZ RDS deployment.

Customers globally sounds good Global Accelerator More Work develope migrate app to Lambda Amazon Relational Database Service (Amazon RDS) for PostgreSQL and for MySQL now support a new Amazon RDS Multi-AZ deployment option with one primary and two readable STANDBY database (DB) instances across three Availability Zones (AZs). https://pages.awscloud.com/Deep-dive-on-Amazon-RDS-Multi-AZ-with-two-readable-standbys_2022_0408-DAT_OD.html For a standard accelerator, you can add one or more regional resources, such as load balancers or EC2 instances endpoints, https://docs.aws.amazon.com/global-accelerator/latest/dg/introduction-get-started.html
