A city finance team currently runs PostgreSQL on EC2 and spends staff time on backups and database engine patching. They want AWS to handle those operational tasks. What should they choose?
Select an answer to reveal the explanation.
Short Explanation
Running Postgres on EC2 is like owning the whole restaurant kitchen—you cook and you fix the dishwasher. RDS is closer to a managed kitchen where the vendor handles backups and patching so your team can focus on the recipes (the data). Glacier is cold archives, CloudFront is a CDN—neither is your online SQL database.
Full Explanation
Amazon RDS is a managed relational database service that automates operational tasks such as backups and database engine patching. Self-managing PostgreSQL on EC2 leaves those duties with the customer. Amazon S3 Glacier Deep Archive is for long-term archival storage, and Amazon CloudFront is a content delivery network—neither replaces a managed transactional PostgreSQL service.
