Choose the description that is incorrect regarding serverless architecture.
Show answer & explanation
Option C is incorrect because serverless architectures do NOT have zero-second initialization. Cold starts are a well-known limitation where newly provisioned instances introduce latency (typically 100ms to several seconds) before the application can process requests. Options A, B, and D are all accurate descriptions of serverless characteristics: on-demand scaling with cost reduction (A), pay-per-use billing (B), and reduced low-level infrastructure control compared to IaaS (D).
Step-by-step Derivation:
Analyze each statement against serverless architecture properties:
A) TRUE - Serverless functions scale automatically based on demand and incur no charges during idle periods.
B) TRUE - Billing is based on execution metrics (invocations, memory, duration) with no cost when not in use.
C) FALSE - Cold starts are a significant limitation. When new instances are initialized, there is initialization latency (not zero-seconds). Warm instances may respond quickly, but scaling up introduces delays.
D) TRUE - Serverless abstracts away server management but limits OS-level tuning; IaaS (like VMs) offers more granular control.
The question asks for the INCORRECT statement, making C the answer.
