 The best way to distribute large scientific datasets is via the Cloud, in [Cloud-Optimized formats](https://guide.cloudnativegeo.org/) [^1]. But often this data is stuck in legacy pre-Cloud file formats such as netCDF.

 ### VirtualiZarr vs Kerchunk?
 
-VirtualiZarr (pronounced like "virtualizer" but more piratey) grew out of [discussions](https://github.com/fsspec/kerchunk/issues/377) on the [kerchunk repository](https://github.com/fsspec/kerchunk), and is an attempt to provide the game-changing power of kerchunk in a zarr-native way, and with a familiar array-like API.

 You now have a choice between using VirtualiZarr and Kerchunk: VirtualiZarr provides [almost all the same features](https://virtualizarr.readthedocs.io/en/latest/faq.html#how-do-virtualizarr-and-kerchunk-compare) as Kerchunk.
