The hub-and-spoke method is superior to point-to-point data synchronization because it scales more easily, synchronizes data more accurately, is easier to maintain, more secure, and more affordable. The hub-and-spoke system allows for only one connection per app, reducing the number of connections required as the business grows, making it less prone to errors and inconsistencies. It also provides a central point of truth, ensuring accurate and consistent data across all apps. Additionally, the hub-and-spoke model is easier to maintain and clean up, reduces exposure to security breaches, and can be more cost-effective in the long run despite potentially higher upfront costs.
