Question
A company wants to move its environment from on premises to the cloud without vendor lock-in. Which of the following would BEST meet this requirement?
Options
- ADBaaS
- BSaaS
- CIaaS
- DPaaS
Explanation
IaaS provides standardized infrastructure resources that can be replicated across providers, offering the greatest portability and the least vendor lock-in.
Common mistakes.
- A. DBaaS uses provider-specific managed database engines, connection APIs, and backup mechanisms that tie the organization tightly to a single vendor's implementation.
- B. SaaS is fully managed by the vendor and hosted entirely on their infrastructure, giving the customer no control over portability or migration paths.
- D. PaaS abstracts the underlying infrastructure but relies on vendor-specific runtimes, deployment pipelines, and APIs, making it significantly harder to migrate to a different provider.
