WaveRadar: See and Understand EC2 Spot Price History Like Never Before

Introducing WaveRadar

There aren't really any great tools for understanding and comparing historical Spot EC2 prices for the 600+ instances available on AWS. To solve this, we created WaveRadar, an interactive dashboard for viewing Spot EC2 prices across all major AWS regions. WaveRadar lets you easily identify the regions offering the lowest $/hour for a given instance or instance family. It can also help you quickly compare the relative price performance $/core and $/memory of different EC2 instances at recent and historical Spot market prices. Use WaveRadar as a free FinOps tool to make more informed decisions around cost optimization, just sign up for a free account via the steps below.

To access WaveRadar, follow these simple steps:

1. Sign up for an MMCloud account (completely free) and sign in.
