COST 10. How do you manage and/or consider the adoption of new services?
At AWS, our goal is to help you architect as optimally and cost effectively as possible. New services and features might directly reduce your costs. A good example of this is Amazon Glacier, which offers a low-cost, “cold” storage solution for data that is infrequently accessed, yet must be retained for business or legal reasons. Another example is Reduced Redundancy Storage for Amazon S3, which allows you to elect to have fewer copies of your Amazon S3 objects (lower levels of redundancy) for a reduced price. There are implications to consider when making these decisions, for example: “What does it mean to have fewer copies of my data?” or “Will I need to access this data more than I realize?”
Best practices:
 Meet regularly with your AWS Solutions Architect, Consultant, or Account Team, and consider which new services or features you could adopt to save money.
