Q188. An ecommerce company hosts its analytics application in the AWS Cloud. The application generates about 300 MB of data each month. The data is stored in JSON format. The company is evaluating a disaster recovery solution to back up the data. The data must be accessible in milliseconds if it is needed, and the data must be kept for 30 days.Which solution meets these requirements MOST cost-effectively?
- A. Amazon OpenSearch Service (Amazon Elasticsearch Service)
- B. Amazon S3 Glacier
- C. Amazon S3 Standard ✓
- D. Amazon RDS for PostgreSQL
Correct Answer: C. Amazon S3 Standard
Explanation
C. Amazon S3 StandardAmazon S3 Standard is the most cost-effective solution for storing data that needs to be accessed quickly and frequently. The analytics data generated by the ecommerce company is only 300 MB per month, which is well within the limits of the S3 Standard storage class. Additionally, S3 Standard provides 99.99% availability and is designed to be highly durable for long-term storage of data. With S3's versioning feature, the company can keep multiple versions of the same data for the same cost as storing a single copy.Amazon OpenSearch Service and Amazon RDS for PostgreSQL are database services and not intended for simple file storage. They are intended for more complex data storage needs and are more expensive to operate than S3 Standard. Amazon S3 Glacier is designed for long-term storage and data archival purposes. While it is a low-cost storage solution, it is not ideal for data that needs to be accessed in milliseconds, as data retrieval times range from minutes to hours.
