AWS Reserved Instances are often the most effective way to reduce your AWS infrastructure costs. But it can take hours to calculate how many reservations you need— and if you buy the wrong quantity or types of Reserved Instances, you could end up spending more money than you save.
That’s why Cloudability is pleased to announce the beta release of our new Reserved Instance Planner tool. Now you can get accurate Reserved Instance purchasing recommendations instantly and without the risk of spreadsheet errors. Say “hello” to the Cloudability Reserved Instance Planner.
Cloudability’s Reserved Instance Planner instantly shows you the total number of recommended RI purchases for each instance type and availability zone, the upfront cost of those purchases, and the estimated savings that will result from those purchases if you maintain your usage patterns.
Behind the scenes Cloudability is using a sophisticated algorithm to calculate the number of instances of each type, OS and availability zone that are running each hour of the reporting period. The tool then uses that data to determine the frequency that each hourly instance count meets the break even points for every reserved instance type—including Lights, Mediums, and Heavies.
The rationale and break even points for each recommendation are then compared to your existing reserved instance portfolio. You get an easy to understand list of what you should buy more of, and which reservations you may have over-provisioned. To make things even clearer, you’re presented with an easy to understand hourly frequency distribution histogram that give you confidence in the recommendation by visualizing the underlying data for each one.
No other RI tool can give you this level of detail.
Figuring out how to cover the volatile peaks of usage with Light and Medium reservations is a huge challenge, which causes many customers to avoid using Light and Medium RIs altogether— losing out on potential savings. The Cloudability Reserved Instance Planner can itemize recommendations for each reservation type so that you are always purchasing the optimum blend of reservation types.
Because Cloudability warehouses your utilization data over time, recommendations are based on rich historical usage patterns. You can select any date range in the last 90 days to make more informed decisions and exclude historical usage spikes from your recommendations. This provides much deeper levels of confidence and control than the two weeks of data provided by AWS directly.
Once you have your Reserved Instance recommendations, use Cloudability’s EC2 Usage Analytics to understand the utilization and future plans for the instances used in the recommendation before you purchase.
When chosen correctly, Reserved Instances are an invaluable—and now easy— cost savings tool. With Cloudability, you can buy Reserved Instances with confidence and without spending days in a spreadsheet. Whether you’re one of the 70% of Cloudability customers who use RIs or are simply ready to try them for the first time, Cloudability Reserved Instance Recommendations can ensure that you get the most out of your RIs.
