Question

Difficulty: EasyIdentify design principles of the AWS Cloud

An application administrator notices that one of the virtual servers in their fleet is experiencing performance degradation. Instead of spending time troubleshooting the server, the administrator terminates it and lets the system automatically launch a new instance from a pre-defined template. Which AWS Cloud design principle does this practice demonstrate?

  1. A
    Tightly coupled components
  2. Disposable resources instead of fixed serversAnswer
  3. C
    Monolithic application design
  4. D
    Static over-provisioning

Answer

Disposable resources instead of fixed servers
The correct answer is correct because treating resources as disposable means that instead of spending resources to troubleshoot, patch, and maintain a failing or degraded virtual server, you terminate the instance and launch a clean one from a standard template. This ensures consistency, reduces downtime, and aligns with the AWS design principle of using disposable resources instead of fixed servers.

Step-by-Step Solution

1
Analyze the administrator's action of terminating a degraded server and replacing it automatically with a clean template, rather than repairing it.
Identify that the server is treated as temporary and replaceable (disposable) rather than a fixed asset that must be maintained and repaired.
To determine how this operational approach relates to standard cloud infrastructure design principles.
2
Map the identified behavior to the standard AWS Cloud design principles.
The practice matches the principle of 'Disposable resources instead of fixed servers' because the instance is terminated and replaced dynamically.
To select the correct design principle that matches this dynamic replacement pattern.

Key Concept

Treating servers as disposable resources instead of fixed, long-lived assets is a core AWS design principle that simplifies operations and improves reliability.
