Which of the following is an AWS value proposition that describes a user's ability to scale infrastructure based on demand?

Resource elasticity is a core value proposition of AWS and cloud computing. It refers to the ability to acquire resources as you need them and release resources when you no longer need them. This allows you to automatically scale your infrastructure up (scale-out) to meet increasing demand and scale it down (scale-in) during quieter periods. This eliminates the need for guessing capacity upfront, ensuring you only pay for the resources you actually consume, thereby optimizing both performance and cost.

A. Speed of innovation: This value proposition relates to the agility and reduced time-to-market for developing and deploying new applications, not the scaling of infrastructure capacity.

C. Decoupled architecture: This is a system design principle where components are loosely coupled. While it facilitates scalability, it is an architectural pattern, not the value proposition of scaling itself.

D. Global deployment: This refers to the ability to easily deploy applications in multiple geographic regions around the world, which is about reach and latency reduction, not scaling based on demand.

1. AWS Whitepaper

"Overview of Amazon Web Services" (August 2023): In the section "The Benefits of AWS

" the document states

"Instead of waiting weeks or months for hardware

you can instantly deploy new applications

instantly scale up as your workload grows

and instantly scale down based on demand." This directly describes elasticity. (p. 4)

2. AWS Documentation

"What is Cloud Computing?": Under the section "Six Advantages of Cloud Computing

" the principle "Stop guessing capacity" is explained: "With cloud computing

you can access as much or as little capacity as you need

and scale up and down as required with only a few minutes’ notice." This is the definition of elasticity.

3. AWS Whitepaper

"AWS Cloud Adoption Framework: An Actionable Guide to Cloud Transformation" (July 2021): The "Platform Perspective" of the CAF focuses on principles for implementing new solutions and migrating workloads. It emphasizes the capability to "scale IT resources up and down based on business or workload demands

" which is a direct reference to resource elasticity. (p. 13)
