A company runs a multi-tier web application on premises. The web application is containerized and runs on Linux hosts connected to a PostgreSQL database that contains user records. Operational overhead of maintaining infrastructure and capacity planning limits growth. A solutions architect must improve the application's infrastructure. Which combination of actions should the solutions architect take? (Choose two.)

Migrating the PostgreSQL database to Amazon Aurora reduces operational overhead because Aurora is a fully managed, highly scalable, and fault-tolerant relational database service. It handles patching, backups, and replication automatically. Migrating the web application to AWS Fargate with Amazon ECS eliminates the need to provision, configure, or scale EC2 instances for containers, significantly reducing infrastructure management and capacity planning concerns. Fargate is a serverless compute engine for containers, allowing you to focus on your application rather than the underlying infrastructure. Migrating to Amazon EC2 instances alone would still require managing the underlying servers, negating the benefit of reduced operational overhead. Setting up Amazon CloudFront is beneficial for content delivery but doesn't address the core infrastructure management or capacity planning issues of the application or database. Amazon ElastiCache improves performance by caching data but doesn't replace the need for a managed database or container orchestration.
