EC2 instances are billed based on their instance type, and selecting the right size can significantly reduce your cloud infrastructure costs. Oversized instances waste resources and result in higher expenses, while undersized instances may lead to performance issues.

As your application or workload evolves, you may need to scale your infrastructure up or down. Rightsizing makes it easier to adapt your environment, ensuring that you can meet changing demands without incurring excessive costs. This solution helps dynamically rightsize your environment to reduce costs and maximize your cost-performance ratio on a regular basis.
