Reserved Instance (RI) Recommendations

RI (Reserved Instances) Recommendations

This RI Utilisation Dashboard is available as part of the Cost Module. Reserved Instances in AWS, Azure provides excellent cost saving benefit when you commit for certain level of usage for specific products such as instance types or databases.

If you have instances and databases that you consistently use for the whole month and you have a projection for such usage for longer duration such as a year or 3 years, you must consider purchasing reserved instances. Production workloads are good candidates for RI since they will be running 24x7x365. You can also group the usage from multiple instances of a specific family and still get the RI discount benefit.


The summary section provides the consolidated numbers for the following

  • Azure – Total Potential Cost Savings (by purchasing RIs)
  • Azure – Total no. of RIs that are recommended to be purchased
  • AWS – Total Potential Cost Savings (by purchasing RIs)
  • AWS – Total no. of RIs that are recommended to be purchased
