Which AWS service should the company use to meet these requirements?

Explanations:

AWS IoT Core is designed for connecting IoT devices to the cloud, but it relies on internet connectivity to send data to AWS. Since the scenario involves intermittent or no connectivity at sea, this option is not suitable for processing and moving data while offline.

Amazon Lightsail is a simplified cloud service for running applications and websites but does not provide the necessary capabilities for collecting and processing data from sensors on cargo ships at sea. It is not designed for offline data handling or the specific requirements mentioned in the scenario.

AWS Storage Gateway is primarily for hybrid cloud storage solutions that integrate on-premises environments with AWS storage. It does not cater specifically to the needs of collecting and processing data at sea, especially with the requirement of intermittent connectivity.

AWS Snowball Edge is designed for edge computing and data transfer in environments with limited or no connectivity. It allows data to be processed locally on the device and later transferred to AWS when connectivity is available, making it the ideal solution for collecting, formatting, and processing sensor data at sea.
