Abstract
In this chapter, we will present the general cloud workflow system architecture. System architecture in general decides how the system components are organised in different layers and how they communicate with each other. In Sect. 2.1, we will first introduce the general cloud software architecture. Afterwards, Sect. 2.2 will present the general architecture of cloud workflow system. Meanwhile, for each of the general architecture, the concrete architecture of a commercial system is also demonstrated.

Notes
- 1.
A cloud workflow system can be encapsulated as a platform service, i.e. PaaS (platform as a service). In such a case, the platform layer is maintained by external cloud service providers.
- 2.
The fabric layer can also be a virtual collection of local computing infrastructure (i.e. private cloud) and the commercial computing infrastructure (i.e. public cloud), i.e. hybrid cloud.
