A company's sustainability team wants to reduce the environmental impact of the AWS workloads it runs.

It is reviewing the Sustainability pillar of the AWS Well-Architected Framework to decide which actions fall to the company, and which are handled by AWS in its data centers.

Which action is the company's responsibility?

Choose one answer.

  1. A. Optimizing workloads and resource use so that fewer resources need to be deployed
  2. B. Sourcing renewable power for the data centers that run AWS services
  3. C. Practicing water stewardship at the facilities that host AWS infrastructure
  4. D. Designing efficient shared infrastructure inside AWS data centers
Show the answer and explanation

Answer: A

  • A. Right: Correct. The Sustainability pillar makes customers responsible for sustainability in the cloud, which means optimizing their workloads and resource use so they deploy as few resources as needed. Learn more: The shared responsibility model: Sustainability Pillar (opens in a new tab)
  • B. Wrong: Incorrect. Sourcing renewable power is part of sustainability of the cloud, which AWS is responsible for across its data centers. Customers do not choose the energy supply for AWS facilities.
  • C. Wrong: Incorrect. Water stewardship at AWS facilities is part of sustainability of the cloud, and AWS is responsible for it. A customer does not manage water use at those sites.
  • D. Wrong: Incorrect. Efficient shared infrastructure inside AWS data centers is AWS's responsibility. Customers can still design their own workloads to use that infrastructure efficiently.

Explanation

The Sustainability pillar splits responsibility. AWS is responsible for sustainability of the cloud, including renewable power, water stewardship and efficient shared infrastructure. Customers are responsible for sustainability in the cloud, which means optimizing their own workloads and resource use.
