To enable its customers to optimize their Cloud architecture to better control their budget, AWS now offers an optimization recommendation interface directly integrated with its Cloud Cost Management tool.
This tool identifies two main types of cloud instances with optimization potential: "useless" and "underutilized" resources. AWS presents as useless a resource used at less than 1% of its total capacity. The "under-utilised" category includes resources used between 1% and 40% of their total capacity.
This categorization of cloud resources allows AWS to provide separate recommendations. As part of an unnecessary resource, Amazon's Cost Explorer will simply advise you to turn off your instance to limit waste. As part of an underutilized resource, AWS will instead direct you towards a logic of resizing your product, to better match your real needs. This is generally referred to as "rightsizing" Cloud instances.
The AWS recommendation interface presents the information as follows:
- the number of opportunities detected
- an estimate of the achievable monthly savings
- a total percentage of the possible savings
