Altura Software employs 12 developers who want to build and deploy a customer portal quickly. They do not want to manage servers, operating systems or runtime patching, but they want full control of the application code and data they create. Which model best fits, and what does it imply?

PaaS fits best. The provider manages servers, operating systems and runtime, which removes the patching burden, while Altura's developers keep control of the application code and data they build. SaaS would supply a finished product, and IaaS would leave Altura managing the operating system.

  1. ASaaS, because the provider supplies the finished portal and Altura only configures it
  2. BPaaS, because the provider manages the underlying infrastructure and runtime while Altura controls its applications and dataCorrect
  3. CIaaS, because Altura must manage the operating system and runtime to retain control of its code
  4. DA private cloud, because only that model allows control of application code

Explanation

PaaS gives a managed development and deployment environment: the provider handles infrastructure, operating system and runtime, and the customer controls its own applications and data. SaaS would not let Altura build its own portal, and IaaS would leave the patching burden Altura wants to avoid.
