Question
A company would like to move all its on-premises platforms to the cloud. The company has enough skilled Linux and web-server engineers but only a couple of skilled database administrators. It also has little expertise in managing email services. Which of the following solutions would best match the skill sets of available personnel?
Options

- BRun the web servers, databases, and email in SaaS.
- CRun the web servers in IaaS, the databases in PaaS, and the email in SaaS.
- DRun the web servers, databases, and email in IaaS.
Explanation
Matching cloud service models to available skills means using IaaS where staff are proficient, PaaS where expertise is limited, and SaaS where no in-house expertise exists.
Common mistakes.
- A. Running web servers in PaaS removes OS-level control that the skilled Linux and web engineers are qualified to manage and would use effectively in IaaS.
- B. Running everything in SaaS wastes the company's substantial Linux, web-server, and database administrator expertise by offloading work those staff are fully capable of handling.
- D. Running everything in IaaS would require the small DBA team to also manage database infrastructure at a level beyond their capacity, and would demand email expertise the company does not have.
