Use Case Pattern #1: IaaS and PaaS
Use Case Pattern #1: IaaS and PaaS
The general uses of infrastructure-as-a-service (IaaS) and platform-as-a-service (PaaS) service models, 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 IaaS and PaaS are discussed: computing; web hosting; storage; backup and recovery; database services; application development; application testing and application integration.
