Which solution will meet these requirements?
Migrate both applications to AWS Lambda. Create an Amazon S3 bucket to exchange data between the applications.
Migrate both applications to Amazon Elastic Container Service (Amazon ECS). Configure Amazon FSx File Gateway for storage.
Migrate the simulation application to Linux Amazon EC2 instances. Migrate the visualization application to Windows EC2 instances. Configure Amazon Simple Queue Service (Amazon SQS) to exchange data between the applications.
Migrate the simulation application to Linux Amazon EC2 instances. Migrate the visualization application to Windows EC2 instances. Configure Amazon FSx for NetApp ONTAP for storage.
Explanations:
AWS Lambda is not suitable for applications that require persistent storage for output data and regular access to that data, as it is designed for event-driven compute services. Additionally, the requirement for SMB file system access by the visualization application cannot be fulfilled with Amazon S3.
While Amazon ECS could host both applications, it does not address the requirement for file system compatibility. Amazon FSx File Gateway provides a way to access Amazon S3 but does not support SMB, which is required for the Windows visualization application.
This option migrates the applications to EC2, which is appropriate, but using Amazon SQS for data exchange does not meet the requirement for file system access. Both applications require file-based access rather than message queuing for data exchange, leading to incompatibility.
This option correctly migrates both applications to EC2 instances that match their operating system requirements. Additionally, Amazon FSx for NetApp ONTAP provides an SMB-compatible file system that the Windows visualization application can use, enabling direct access to the simulation output without data duplication.
In my experience, the answer is:
Migrate the simulation application to Linux Amazon EC2 instances. Migrate the visualization application to Windows EC2 instances. Configure Amazon FSx for NetApp ONTAP for storage.
