Hub-and-Spoke and Point-to-Point [Series#2: I am Data!]

Surely, these terms are new for you but as we will go into details you will be able to comfortably say that you knew these already ??.

Let’s decode these…..

Point-to-Point vs Hub-and-Spoke Data Synchronization Architecture

Point-to-Point model (PP) connects all applications with each other e.g., if there are 5 applications then there will be many connections as depicted in below picture.

Hub-and-Spoke model (SP) creates a new centralized connection points called as Hub and all applications will ONLY connect with centralized ONE Hub.

We can clearly see Hub-and-Spoke model is much better in access management, flexible, cheaper, secure etc. as compared to Point-to-Point model.

Examples of Hub-and-Spoke model are Data Warehouse (dimensional), Data Hub, Data Fabric etc. which serves as single point of truth for all enterprise users.

Key Items

• User Access: SP model can management user access matrix at centralized place as compared to PP model.
• Security: As all users will be connecting to one centralized Hub, risk of security breach will be less in SP model as compared to PP model
• Flexibility: In SP model, Hub is easy to incorporate those new requirements which doesn’t need to implement in source systems.
• Cheaper: In SP model, though Hub implementation requires initial investment but once it’s implemented all new requirements cost will have much cheaper impact as all changes will go in Hub as compared to each application in PP model.

Cheers.
