<p dir="ltr">So, my need is to process EO data closest possible where they are stored.<br>
Imagine a huge object storage or bucket or the like which is surrounded by cloud compute instances. Given the data size between some Terabytes up to Petabytes (e.g. Sentinel) I need to minimize whatever data transfer or extra (format) conversion.</p>
<p dir="ltr">Even's suggestion to use FUSE to mount<br>
buckets in the file system will be something to try.</p>
<p dir="ltr">However, the location concept is also causing some friction here: Sentinel data are stored in many different zones i.e. would result in many different locations. I have no solution to that yet but this issue plus the need to minimize bandwidth usage is the key for a successful cloud storage based processing.</p>
<p dir="ltr">So I started with thinking about how to connect to current EO storages.</p>
<p dir="ltr">Best.<br>
