The general uses of the software-as-a-service (SaaS) service model, together with their pros and cons, are discussed in this chapter using a SWOT analysis. The general uses are described as uses cases; a use case defines the requirements and the sequence of interactions in order to effect a solution. When commonality is detected between use cases that implement a distinct solution, then it is called a use case pattern. These use case patterns can generally be implemented using micro-services. When standardized and implemented in the cloud, such micro-services are referred to as cloud cells. Thus cloud cells implement use case patterns. The following use case patterns for SaaS are discussed: customer relationship management; billing and invoicing; collaboration, instant messaging and email; Bring-Your-Own-Device; office productivity and image rendering.

Keywords:   Cloud patterns, SaaS use case, Use case patterns, Cloud cells, Cloud SWOT analysis
