Dear Zibusiso,
as you are asking for a solution that process data on server side, I guess the best way is to use WPS.

Depending on what you want to do with your data, you may need to use GDAL, GRASS, SAGA-GIS, OTB or another library/engine. As you can see from here [1] all those engines are supported in the ZOO-Project.

In case you want to use raster processing without having to create your own web application but are willing to publish generated web applications providing raster processing. Then you may try the MapMint software [2] directly, this way you can process your raster data.

> Map algebra for raster is easy on desktop packages and through hardcoding through Python or R. I want to implement an online solution that takes base data (created on desktop) and does some raster algebra on  it in a web GIS server environment such as GeoServer or MapServer. 
> Basically what I want to achieve is to do simple things like dividing two images and generate a third, ratio image to be displayed in the webpage.
> Is this feasible? If yes... how can this be done and where can I get help or examples. (Preferred server choice is geoserver, if anyone has knowledge about this)
> You assistance/direction  will be greatly appreciated.
