Also known as: Hub-Spoke Topology
An integration pattern where a central hub mediates and governs connections to multiple spokes, simplifying connectivity and control.
DESCRIPTION
Hub and spoke centralizes integration through a core platform that connects to systems on the periphery. It reduces the number of direct connections, simplifying routing, transformation, and governance. The hub often provides mediation, monitoring, security, and policy enforcement. It eases scalability and change management compared to point-to-point webs, though it risks central bottlenecks. Implementations include ESBs, iPaaS, and shared data platforms. The model is common for data distribution, analytics hubs, and network architectures. Modern adaptations introduce domain boundaries and self-service while maintaining centralized controls.
ALTERNATIVE DEFINITIONS
Wikipedia
The hub and spoke model is a system of connections arranged like a wheel, in which all traffic moves along spokes connected to a central hub.
Uses an intuitive wheel metaphor emphasizing centralized connectivity.
Microsoft Azure Architecture Center
The hub-spoke topology is a network topology that uses a central hub to manage connectivity to multiple spokes.
Focuses on cloud network topology and centralized management.

TOP QUESTIONS
Why choose Hub and Spoke over Point to Point Integration?
It reduces integration complexity, centralizes governance, and simplifies scaling by avoiding n-squared connections among systems.
Category: Alternatives
What risks does Hub and Spoke introduce?
The hub can become a bottleneck or single point of failure. Proper redundancy, autoscaling, and operational monitoring are essential.
Category: Risks
How does Hub and Spoke relate to an ESB?
An ESB is a common technology to implement hub-and-spoke, providing routing, transformation, and policy enforcement.
Category: Example
Is Hub and Spoke compatible with Data Mesh?
Yes, a central platform can offer shared capabilities while domains own data products, balancing autonomy with standards.
Category: Opinion
What is a hot topic around Hub and Spoke today?
Cloud-native hub designs using API gateways, event brokers, and iPaaS to reduce operational overhead are popular.
Category: Topic
How is a Hub and Spoke architecture governed?
Central teams define policies, security, and observability in the hub, while spokes integrate through standardized interfaces and contracts.
Category: Management
What are alternatives to Hub and Spoke?
Point-to-point, mesh topologies, or a bus architecture can be suitable depending on autonomy and scale requirements.
Category: Alternatives
Where should I start with Hub and Spoke in the cloud?
Use vendor reference architectures, establish network segmentation, and deploy a central hub with shared services and governance controls.
Category: Learning
What is the biggest misunderstanding about Hub and Spoke?
That it always centralizes ownership; in practice, it centralizes capabilities while allowing domain ownership of data and services.
