Question

Difficulty: MediumIdentify design principles of the AWS Cloud

A financial research firm needs to run a complex risk analysis simulation once a week. The simulation requires a large cluster of compute instances for six hours. The firm uses infrastructure as code to automatically provision the instances, run the simulation, and then immediately terminate the entire cluster. Which AWS Cloud design principle is directly demonstrated by this operational workflow?

  1. A
    Elasticity
  2. B
    Monolithic design
  3. Disposable resources instead of fixed serversAnswer
  4. D
    Scalability

Answer

Disposable resources instead of fixed servers
The principle of using disposable resources instead of fixed servers dictates that infrastructure should be treated as temporary and easily replaceable. By programmatically launching a compute cluster for a weekly simulation and terminating it immediately after completion, the firm optimizes cost and resource utilization, avoiding the expense of maintaining idle, permanent servers.

Step-by-Step Solution

1
Analyze the operational workflow described in the scenario.
The firm spins up resources on demand for a short-lived task (six hours) and completely tears them down afterward.
This establishes that the infrastructure is temporary and not a permanent fixture.
2
Identify the AWS design principle that relates to treating infrastructure as temporary, programmatically defined assets.
The principle is 'Disposable resources instead of fixed servers'.
This principle leverages cloud automation to provision and terminate environments dynamically, eliminating the need for fixed, continuous infrastructure.
