I've developed an application involving a GeoServer (2.17) instance deployed on an on-premise web server. The data consists of mosaics of GeoTIFF images stored on the web server file system.

Now I need to port the architecture on Azure platform. I need to persist my raster files on an Azure Data Lake Gen2 instance. I know that there are many possible solutions for the GeoServer deployment on Azure (VM, container, AppService, etc), but I can't find a way to connect GeoServer to the storage.

I think I can set up a virtual machine using Azure services to deploy GeoServer and duplicate raster files on the VM's file system but I'd like to connect Geoserver to Azure Data Lake directly.

I found that it is possible to read files from Amazon S3 buckets, but I didn't find a similar solution for Azure. I also found this solution but it works with Azure Blob Storage that is different from Azure Data Lake.

This plugin supports the use of the Azure Blob storage as storage medium for GeoWebCache settings. Azure Datalake Gen 2 is built on top of Azure Blob so this should work. I haven't done any Geoserver work since 2014...

  • Thanks for the answer. I've never used GeoWebCache or BlobStores in my application but I think I need to use Azure Data Lake as the Geoserver data directory. Are the two concepts related?

  • GeoWebCache is a tiling service but I imagine it can host your raster files.

There is currently (May 2020) any GeoServer plugin to allow access to data stored on Azure, either in the blob store or the lake. Such a plugin could be written based on either the older S3 code or the newer COG plugin.

If you are unable to develop the code with your own resources there are commercial companies that can. (Disclaimer, I work for one of those companies.)

  • Thanks for the answer. The S3 plugin works only with single raster files or with ImageMosaics too?
