AWS Storage GatewayYour company has uploaded large amounts of aerial image data (S3). You used Rabbit MQ, an Open Source messaging system, to send job information to the servers. Once the data was processed, it would be taped and shipped offsite. Your manager advised you to stick with the current design and to use AWS archival storage to reduce costs. Which is correct? [PROFESSIONAL] Use SQS to pass job messages. Cloud Watch alarms can be used to terminate EC2 worker instances if they become inactive. After data has been processed, change the storage category of the S3 objects into Reduced Redundancy Storage.
Install Auto-Scaled workers that are triggered by queue depth and use spot instances to process messages within SQS. After data has been processed, change the storage category of the S3 objects so that they have Reduced Redundancy Storage.
Install Auto-Scaled workers that are triggered by queue depth and use spot instances to process messages within SQS. After data has been processed, change the storage type of the S3 objects from Glacier to Glacier.
SNS can be used to send job messages. Cloud Watch alarms can be used to terminate spot worker instances if they are idle. After data has been processed, change the storage type of the S3 object Glacier. You are developing a mobile application and want to store user preferences in AWS. This would allow users to have a consistent experience across devices. The preference data for each user will be approximately 50KB. The application is expected to be used by 5 million customers on a regular basis. How can you design a solution that meets these requirements?
