Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 851 discussion

(A,B,D) eliminated. Aurora instances & Amazon RDS use On-Demand or Reserved INSTANCES. These are more expensive than a serverless solution. (C) is correct. Amazon Aurora Serverless automatically starts up, shuts down & scales capacity up or down based on your application's needs; you pay only for capacity consumed.

Yes but its asking for the most cost effective. B would cause frustration for developers if it was terminated unexpectedly. The answer should be C so developers can easily access when they are needed and auto scales based on demand

A - Aurora = Overkill and expensive. B - Just like A. C - Aurora Serverless scales based on usage and can automatically scale down to zero when the database is not in use. This is ideal for a development environment where databases are only needed during active work hours. D - Money is not an issue here I think. The real problem is - there’s no guarantee that the database would be automatically available when the developers need it. The need for a manual process to monitor and terminate idle databases introduces operational overhead and the potential for human error.

when i see "managed PostgreSQL databases", i immediately look for serverless

I think the answer correct is B as the database should be managed by the developer and Each developer needs a separate DB.

Requirement: Each developer needs a separate DB. In a cluster, DB is shared among developers.

Guys, listen to the question, each developer -> a separate managed PostgreSQL DB. this is the task. Then Most cost-effective comes. If you get a cheaper thing that does not fulfull the task, you are wrong. Question: Can each developer get a separate DB for himself from the cluster?

Answer C: We know we require Service Catalog. This option provides workflow no how it works

AnswerC Using Aurora Serverless solution + AWS Service Catalog features seems to be a good idea https://aws.amazon.com/rds/aurora/serverless/ https://aws.amazon.com/servicecatalog/features/

Only option B can have limited size database

Aurora Serverless = inicia, encerra e escala a capacidade automaticamente de acordo com as necessidades. AWS Service Catalog = catalogo de serviços que usuarios podem utilizar, dentro das configurações permitidas. https://aws.amazon.com/pt/rds/aurora/serverless/ https://aws.amazon.com/pt/servicecatalog/

I thin is c

With AWS Service Catalog, you can meet your compliance requirements while making sure your customers can quickly deploy the cloud resources they need.
