AWS provides EBS Block Public Access at the AWS Organizations level, which, when enabled, prevents EBS snapshots from being shared publicly across all member accounts. This is an organization-wide control that requires minimal configuration and no ongoing monitoring to prevent public sharing.

This directly satisfies the requirement:

Covers all accounts managed by Organizations.

Explicitly prevents public snapshot sharing.

Has the least operational overhead because it is a single centralized control.

AWS Config (Option A) only monitors and alerts, but does not prevent public sharing.

An IAM policy in the root account (Option C) is harder to enforce consistently across all accounts and may not cover all permission paths.

CloudTrail (Option D) only logs events and does not prevent public access.

For a MySQL database experiencing high write operations, using Amazon RDS with Provisioned IOPS (io1 or io2) SSD storage is recommended to achieve consistent and low-latency performance. Provisioned IOPS allows you to specify a desired IOPS rate, which is crucial for write-intensive workloads.

Monitoring write operation metrics through Amazon CloudWatch enables you to observe performance and adjust the provisioned IOPS as needed to meet application demands.

Amazon Kinesis Data Streams provides a highly scalable and durable service for ingesting real-time streaming data. By decoupling ingestion and processing, Kinesis can handle large spikes in traffic without service disruption. Lambda functions (or other consumers) can then process the data as it arrives, scaling automatically. This pattern avoids 503 errors due to compute saturation and delivers a resilient, serverless, and highly scalable architecture.
