Overview
This document architectural background, links, and resources for building loosely coupled and reliable
applications, creating distributed systems, and integrating software systems with NServiceBus.
What is SOA 2.0?
In classic SOA, applications exposed their business methods to other applications via web services. This opened
communication, but led to un-maintainable fine-grained integration points, temporal coupling (both systems
have to be up at the same time for either to work), and performance bottlenecks. SOA 2.0 combines
SOA with event-driven architectures (EDA), in which applications (services) publish events to which
other applications can subscribe without being tied together in time. Read this excellent MSDN article for details:
Event-Driven Architecture: SOA Through the Looking Glass.
What is NServiceBus?
A service bus is by nature decentralized, not to be confused with a centralized broker that does ETL and routing,
like BizTalk. NServiceBus can be thought of as the ethernet that enables applications to communicate with each
other organically. NServiceBus provides:
- Publish/subscribe communication
- Reliable messaging with automatic re-tries of failed messages
- Second-level retries for minimizing support effort
- Decentralized workflow/orchestration via Sagas
- Message tracking and failed-message re-submission with ServiceInsight
- Performance monitoring with ServicePulse
