A company’s engineering department is conducting a month-long test on the scalability of an in-house-developed software that requires a cluster of 100 or more servers. Which of the following models is the best to use?
The correct answer is:
✅ D. IaaS (Infrastructure as a Service)
⸻
Explanation:
The company is testing scalability of their own in-house-developed software, which:
• Requires control over 100+ servers
• Is likely not a pre-packaged or platform-native application
• Needs full control over the infrastructure (e.g., OS, networking, scaling behavior)
IaaS provides the most flexibility, allowing the team to:
• Provision virtual machines or bare-metal servers
• Customize the environment
• Scale the infrastructure as needed
• Test performance under various loads
This one is pretty tricky and not really worded well.
PaaS solutions typically give you some level of scalability control, however isn't as granular as IaaS. I feel like the question needs to give us more context in terms of how in-depth or how much control the engineering team needs for scaling their software.
I'd probably lean toward PaaS since it's only a "test" and configuring an IaaS would be much more of an effort.
On second thought, the testing is purely on the scalability.. The engineering team may need a high level of control over that to properly test it..
I can totally see the answer being IaaS as well.
Agree with BrannyBran, PaaS is best for developers and focusing on configuring and maintaining your own software without worrying about the OS or hardware.
PaaS (Platform as a Service) is generally considered the best cloud model for servers as it allows developers to focus on coding and application logic without managing underlying infrastructure, leading to faster development cycles and reduced operational overhead.
