SAP-C02 Question 153
Single answerA company is planning to deploy a new application across multiple AWS Regions to ensure high availability and low latency for its global user base. The application is stateful, and the data needs to be synchronized across regions with minimal latency. The business also requires the ability to perform blue/green deployments to ensure a seamless user experience during application updates. Which deployment strategy satisfies these requirements?
- A
Use AWS Global Accelerator for routing traffic across regions, Amazon S3 for data synchronization, and CodeDeploy for managing blue/green deployments.
- B
Use Amazon Route 53 with weighted routing for traffic distribution, Amazon DynamoDB Global Tables for data synchronization, and AWS Elastic Beanstalk for managing blue/green deployments.
- C
Use Amazon Route 53 with failover routing for traffic distribution, Amazon Aurora Global Database for data synchronization, and AWS CodeDeploy for managing blue/green deployments.
- D
Use AWS Global Accelerator for routing traffic across regions, Amazon RDS with cross-Region read replicas for data synchronization, and AWS CodePipeline with CodeDeploy for managing blue/green deployments.
Show answer and explanation
Correct answer: C
Explanation
Option 3 is correct because it combines Amazon Route 53 with failover routing for high availability, Amazon Aurora Global Database for low-latency cross-region data synchronization, and AWS CodeDeploy for blue/green deployments. This solution meets all the business requirements, including global availability, stateful data synchronization, and seamless application updates.
- A. Incorrect.
AWS Global Accelerator is a good choice for routing traffic across regions, but Amazon S3 is not suitable for synchronizing stateful data with minimal latency. CodeDeploy can manage blue/green deployments, but the overall solution does not meet the requirements for stateful data synchronization.
- B. Incorrect.
Amazon Route 53 with weighted routing allows traffic distribution, and DynamoDB Global Tables can synchronize data across regions with minimal latency. However, Elastic Beanstalk does not natively support blue/green deployments for complex, stateful applications.
- C. Correct.
Amazon Route 53 with failover routing ensures high availability by routing traffic away from unhealthy regions. Amazon Aurora Global Database provides low-latency, cross-region data synchronization, and AWS CodeDeploy supports blue/green deployments, making this option the most suitable.
- D. Incorrect.
AWS Global Accelerator provides efficient routing, and RDS cross-Region read replicas can help with data synchronization. However, RDS cross-Region read replicas are less suitable for low-latency synchronization of highly dynamic, stateful data. CodePipeline and CodeDeploy can manage blue/green deployments, but this approach has limitations compared to Aurora Global Database.
