In this paper, we propose a Software-as-a-Service (SaaS) infrastructure for industry logistics, which is normally constructed with the technology of SOA. We then propose a logistic cloud and design with service pools in it and discuss with some related works and references discussions. In the last section, we implement a SaaS-based global logistic tracking system (SGLTS) structure by abstract the web services in service pools in the Logistic Cloud designed in our research with explanations. Finally, we describe a typical system design and scenario in a normal logistic environment with design patterns of it. Logistic transportations in industries can equipped with different devices such as PCs, tablet PCs, laptops, personal digital assistants with Wireless LAN, 3G network and GPS facilities can be able to install the system with different platforms and can access the web services in the Logistic Cloud that we proposed in our research. Prototype systems that we implement in this paper can have better interoperability and reusability than former systems.
