designing the infrastructure for a queuing system

Hi everyone! We're currently in the process of developing a queuing system for a fintech company to enhance their customer service experience at branches. However, we've reached a crucial stage where we need to make a decision regarding the infrastructure design.

I have two scenarios, and I'm seeking recommendations and suggestions:

1- Under this scenario, all branches would operate directly over the internet, utilizing cloud-based infrastructure. This approach would necessitate reliable internet connections both at the branches and for customers, as they would need access to a web page to create tickets and join the queue.

2- Alternatively, each branch would have a web server operating locally, with synchronization capabilities with a remote server.

Any insights or suggestions you can provide would be incredibly valuable to us as we navigate this decision-making process.
