(Choose 2 answers)
A hospital is migrating from another cloud provider to AWS and wants to modernize as they migrate. The hospital has containerized applications that run on tablets. During spikes caused by increases in patient visits,the communications from the applications to the central database occasionally fail. As a result, the hospital currently has the applications try to write to the central database once. If that write fails, the application writes to a dedicated application PostgreSQL database run by the hospital IT team on premises. Each of the PostgreSQL databases then sends batch information to the central database. The hospital is asking for recommendations on migrating or refactoring the database write process to lower operational overhead. What should the solutions architect recommend? (Select TWO.)
A. Migrate the containerized applications to AWS Fargate.
B. Migrate the local databases to Amazon Aurora Serverless PostgreSQL-Compatible Edition.
C. Migrate the PostgreSQL databases to an Amazon RDS instance with a read replica that replaces each of the local databases.
D. Refactor the applications to use Amazon Simple Queue Service (Amazon SQS) and eliminate the local PostgreSQL databases.
E. Refactor the central database to add an Amazon ElastiCache lazy loading cache in front of the database.
