There were other restrictions also. Here, customers can exchange their Convertible Reserved Instances during its term for other Convertible RIs with a new instance family, instance type, tenancy type, or platform. None of the other instances are from the r5 family, and besides, they are already running with purchased capacity. A market research firm needs to run a major polling campaign for three months.
The workload will be intensive, and the engineers believe this will require a cluster running two c4. The nodes will be removed once the campaign is over. In the first case, the AWS customer could save its costs by selling the extra capacity. In the second scenario, the market research firm could bypass a long-term contract if it found six c4. Other organizations looking for similar capacity could purchase the whole or part of these RIs.
From here, you can choose the OS, instance type, tenancy, the term of the RI, and the payment option. This is the same interface customers use to buy standard or convertible RIs, except it now allows choosing any term between 1 month to 36 months. In the image below, we are searching for t2.

The registration page has to be accessed by the root user of your AWS account. The image below shows the first screen:. After that, a screen appears where you can click on a button to complete your tax-related information:.
Finally, through extensive experiments based on workload data collected from real-world applications, we validate the effectiveness of our online instance selling algorithms by showing that it can bring significant cost savings to cloud users compared with always keeping their reservations in Amazon EC2 reserved instance marketplace. Article :. DOI: Well, in novation and speed to market come first and chances are that those reservations you bought and paid for will go unused, never breaking — even let alone saving any money.
And what is worse, is that you will then go a nd pay on-demand rates for the new instance type. Another common scenario is that despite the best assessment and planning, the projects that the reserved instances were purchased for end early due to some unforeseen circumstance.
You might think th ese are exaggerated , but things like these play out all the time. While AWS does offer convertible reservations and Savings Plans which allow for some flexibility, there are always trade-offs read more about that here. So, is there a way to use reserved capacity in a more risk-free way?
