AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A data analytics company processes daily logs that amount to 400 GB per day. The logs need to be stored for 30 days for compliance purposes and must be readily accessible for querying and analysis. The processing and analysis are performed on Amazon EC2 instances. The company seeks a cost-effective storage solution that provides quick access and minimal management overhead. As a Solutions Architect, which storage solution would you recommend for storing the logs?
Store the logs in Amazon S3 Standard storage class with Lifecycle policy to either adjust storage class or delete them after 30 days.
Set up an EBS Provisioned IOPS SSD (io2) volume for each EC2 instance to store the logs.
Attach multiple EBS General Purpose SSD (gp3) volumes to the EC2 instances for log storage.
Storing the logs in Amazon S3 Standard is the most cost-effective and scalable solution. Amazon S3 offers durable, highly available storage with low latency access, ideal for storing large amounts of data that need to be accessed quickly. It can automatically scale to store the required amount (400 GB per day × 30 days) without upfront capacity provisioning, reducing costs compared to block or file storage options. Amazon EFS is a managed file system ideal for shared access and persistent file storage, but it is more expensive than S3 for large-scale log storage and not optimized for high-volume data storage with lifecycle management. Amazon EBS is a block storage service primarily used for EC2 instance storage. It's not ideal for large-scale, long-term log storage due to its higher cost and manual management overhead compared to S3.
