## Introducing WaveRadar

### Introduction

There aren't really any great tools for understanding the historical Spot EC2 price for the 600+ instances available on AWS, especially not across regions and availability zones. To solve this, we have created **WaveRadar**, an interactive dashboard. WaveRadar can assist you in making informed decisions when selecting AWS EC2 instances and regions for product description = Linux/UNIX. Using WaveRadar, you can lookup EC2 spot price history and compare today's spot/on-demand prices for different instances across all regions and availability zones.
