Amazon EC2 Reservation Instances (RIs), also known as Amazon Elastic Compute Cloud Reserved Instances, are a great way for companies to lower their cloud computing costs. They do this by committing to using Amazon Elastic Compute Cloud instances over a period of one or three years. Reserved Instances are a great alternative to On-Demand instances, which charge users for computing power by the second or hour without requiring a long-term contract. AWS Course in Mumbai

Instead, users can pay an upfront fee to reserve the capacity, and receive a substantial discount off the hourly rate. This model is especially beneficial for organizations that have predictable workloads and require constant computing power over long periods.

There are three types: Standard, Scheduled, and Convertible. Standard Reserved instances offer the greatest discount, but they are also less flexible when it comes to modification. Convertible Reserved instances offer slightly lower discounts, but users can change the instance type or operating system during the term. Scheduled Reserved instances are for workloads which only run in specific time frames. Users can reserve capacity for these times ahead of time.

Reserved Instances provide capacity reservations in specific Availability zones, ensuring the availability of computing resources when required. This is particularly useful for applications that can't tolerate interruptions or delays. The Reserved Instance Marketplace also allows users to resell their Reserved Instances in the event that their needs change before the end term. This provides additional flexibility.
