+# Introduction
+
+OpenDC is a free and open-source platform for cloud datacenter simulation aimed at both research and education.

+Users can construct new datacenter designs and define portfolios of scenarios (experiments) to explore how their designs
+perform under different workloads, schedulers, and phenomena (e.g., failures or performance interference).
+
+OpenDC is accessible both as a ready-to-use platform hosted by us online at [app.opendc.org](https://app.opendc.org), and as
+source code that users can run locally on their own machine or via Docker.
