Introduction - Amazon EC2 Reserved Instances and Other AWS Reservation Models

Introduction

The cloud is well suited for variable workloads and rapid deployment, yet many cloud-based workloads follow a more predictable pattern. For such applications, your organization can achieve significant cost savings by using Amazon Elastic Compute Cloud (Amazon EC2) Reserved Instances. Amazon EC2 Reserved Instances enable your organization to commit to usage parameters at the time of purchase to achieve a lower hourly rate. Reservation models are also available for Amazon Relational Database Service (Amazon RDS), Amazon ElastiCache, Amazon Elasticsearch Service (Amazon ES), Amazon Redshift, and Amazon DynamoDB. This whitepaper discusses Amazon EC2 Reserved Instances and the reservation models for these other AWS services.
