My company develops technology for visitor management. We currently have 2 solutions, one that is in the field, running on on-site hardware. The other is cloud, running on the cloud and processing all visitor related thing remotely.

Management wants us now to build a 3rd product to retire the two previous products and roll them into one. A web service to handle all the data either on site (for robustness) or in the cloud (for simplicity).

In my mind, what I need is a web service to handle the data processing, and it just just be spun up on a local machine or in the cloud, depending on need.

Could anyone suggest some architectures to learn or read more about?

Answer 1

Obviously, you'd need at least an application service layer to encapsulate and expose the API corresponding to the domain logic of your visitor management API. This will structure your architecture using a coarse granularity tha is appropriate for remote services (be it a local webserver or a cloud server).

It's difficult to advise you further, because you let no clue if the visitor management is a very complex functionality, or if it's just some basic features.

Eventually, you could be tempted to package your application as a microservice if it is very focused. In this case, it could help to also using a general API gateway to give you further flexibility for interoperating the service with presentation logic (e.g. server based, client based, etc...) or local services o fthe customer.
