AWS Reserved Instances (RIs) might be commonplace for an average “everyday AWS user”. RIs are a great way to save on your cloud budgets while you work towards optimizing your cloud performance. In case you’re not in the loop, Reserved Instances (RIs) are a pricing model offered by AWS that offers users discounts in return for their long-term commitment to using cloud resources, usually for a period of one or three years. RIs offer better rates as compared to on-demand prices which makes it a highly effective way to cut down costs on the cloud.
Despite the apparent benefits, many AWS users may overlook specific details when leveraging Reserved Instances. One of which is the need for manual intervention at various levels, from turning resources on and off to even tagging resources appropriately enabling you to allocate costs more efficiently. Such repetitive tasks can be automated using a variety of RI management tools designed to optimize the usage of AWS Reserved Instances.
Among these tools are AWS services such as AWS Cost Explorer, AWS Budgets, AWS Trusted Advisor, AWS Instance Scheduler, and more. Additionally, there exist many third-party tools provided by cloud cost optimization service providers like CloudKeeper, which offer enhanced automation features and detailed insights, enabling you to derive maximum business value from your cloud spending.
By harnessing such AWS RI management tools and implementing best practices, you can achieve the following benefits:
-
Cost Optimization:
AWS Reserved Instance management tools can empower you to make the most out of your RI portfolio.

Automating such processes will enable your business to enjoy the best prices on your cloud resources, resulting in significant cloud cost savings over time.
-
Streamlined Operations:
Manually managing RIs on a large scale could be overwhelming even for veteran experts. AWS Reserved Instance management tools can help you streamline these operations by providing a centralized dashboard to monitor, analyze, and even make changes to your RIs.

-
Capacity Reservation for Spot Instances:
AWS Reserved Instance management tools can go beyond RI management. These tools can even assist you in optimizing the usage of Spot Instances. You can take advantage of the cost savings associated with balancing Spot Instances with levels of reserved capacity for critical workloads. RI management tools will help you scale resources automatically during periods of variable demand.
-
Customized RI Notifications:
You can use AWS Reserved Instance management tools to set up custom notifications for approaching RI expirations or even consumption limits. Doing so will help you prevent unintentional renewals, lapses overconsumption of resources for low-priority workloads. By receiving timely notifications, you can make informed decisions about renewing, modifying, or retiring RIs based on your needs.
-
Budgeting & Forecasting:
AWS Reserved Instance management tools offer insights into future cost projections based on your historical usage data, empowering you to plan and allocate resources efficiently. This predictability is essential for financial planning and ensuring that your cloud expenditures align with overall budgetary constraints. Such insights will enable you to make informed decisions about purchasing new RIs, modifying your consumption or even retiring RIs in the future.
