A company is running a traditional web application on Amazon EC2 instances.The company needs to refactor the application as microservices that run on containers.Separate versions of the application exist in two distinct environments: production and testing.Load for the application is variable, but the minimum load and the maximum load are known.A solutions architect needs to design the updated application with a serverless architecture that minimizes operational complexity.Which solution will meet these requirements MOST cost-effectively?Read More →

A company has a multi-tier web application that runs on a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB).The instances are in an Auto Scaling group.The ALB and the Auto Scaling group are replicated in a backup AWS Region.The minimum value and the maximum value for the Auto Scaling group are set to zero.An Amazon RDS Multi-AZ DB instance stores the application’s data.The DB instance has a read replica in the backup Region.The application presents an endpoint to end users by using an Amazon Route 53 record.The company needs to reduce its RTO to less than 15 minutes by giving the application the ability to automatically fail over to the backup Region.The company does not have a large enough budget for an active-active strategy.What should a solutions architect recommend to meet these requirements?Read More →

A company is hosting a critical application on a single Amazon EC2 instance.The application uses an Amazon ElastiCache for Redis single-node cluster for an in-memory data store.The application uses an Amazon RDS for MariaDB DB instance for a relational database.For the application to function, each piece of the infrastructure must be healthy and must be in an active state.A solutions architect needs to improve the application’s architecture so that the infrastructure can automatically recover from failure with the least possible downtime.Which combination of steps will meet these requirements?
