Running head: PUA 421 FINAL Lee 1 PUA 421 Final In cloud computing, there are three types of services offered: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS).

As mentioned previously, PaaS providers also give customers the tools needed to create their own applications. However, the process can be further delved into. According to Holubek and Floyd (2013), PaaS vendors provide a platform that customers can develop with “a collection of application infrastructure (middleware) services,” such as testing, database services, programming languages, and interface design tools (p. 47). These middleware services allow customers to specifically develop their apps however they like, as long as the PaaS provider’s middleware services satisfy their needs.
