The solutions architect should configure an Auto Scaling solution using both scheduled scaling and dynamic scaling techniques. For predictable capacity needs such as regular usage peaks during weekdays, implement scheduled scaling actions to increase the number of instances shortly before expected demand rises and decrease them during lower activity periods, like overnight hours . Additionally, to handle unexpected traffic spikes, configure dynamic scaling with target tracking based on metrics such as average CPU utilization, maintaining performance during unpredicted load increases while opti

Storing images in Amazon S3 buckets while using Amazon DynamoDB to store geographic codes and image S3 URLs is highly cost-effective and meets the scalability and availability needs .

The best solution is to create an S3 Lifecycle configuration to transition the objects from S3 Standard to S3 Glacier Deep Archive after 1 month, as this addresses both the need for frequent access initially and cost-effective long-term storage .
