AWS Certified Solutions Architect Associate SAA-C03 Practice Question
An e-commerce application you are managing has varying peak times throughout the year, with significant spikes in user traffic and data storage requirements during holiday seasons. Considering the need for high availability and consistent performance, while also maintaining cost efficiency, which service would best manage the varying storage requirements?
Use Amazon S3 Intelligent-Tiering to automatically move data between different storage access tiers.
Create a large S3 bucket to handle potential spikes without enabling any auto scaling features.
Store all data in Amazon Glacier to achieve cost savings on storage during low-traffic periods.
Set up multiple EBS volumes with different sizes and manually switch between them based on expected traffic.
Amazon S3's Intelligent-Tiering storage class is designed to optimize cost by automatically moving objects between two access tiers when access patterns change, ideal for data with unknown or changing access patterns. Regular S3 buckets without Intelligent-Tiering would not automatically adjust to access patterns. EBS volumes and Glacier are not suitable for such use cases because EBS does not automatically scale, and Glacier is used for archival purposes with very slow retrieval times, not for immediate access needs.
