Point-to-Point
- Each system is connected to every system through a direct integration
- Easy to implement with only a few systems
- Difficult to scale
Hub & Spoke
- Hub & Spoke can overcome the drawback of Point-to-Point architecture
- Every system connects to the hub.
- All data transfer will be done through the hub.
- Easy to design and implement
- Inability to support large transaction volume
Enterprise Service Bus
- This is much more scalable than Hub-Spoke architecture
- Distributed service architecture
- Employs distributed adaptors
