    # Summary

    The university has decided to invest in a revamp of their library’s digital service, moving it from a legacy system that’s hosted on premise, to a modern, cloud-native system that’s built atop a Platform as a Service like AWS.

    Create a searchable system for storing the library’s catalogue, that library members can use to find and check out books.
