ArcGIS Image Server vs ArcSDE - Comparison of managed raster datasets

Given the response to our last raster post and the interest in image server, I talked with the Raster team to see if we could do a follow up post which compared storing rasters in a geodatabase to using image server. Melanie Harlow, a product engineer on the raster team, directed me to an in-house paper which does exactly that. We were thinking about turning this information into a white paper, but given the amount of interest I thought I’d post it up here first so people can get a look at it.  

Hopefully this information can answer some questions about managing your raster data, and guide you as to which technology is best suited to your workflow.

# re: ArcGIS Image Server vs ArcSDE - Comparison of managed raster datasets

Hi Jon, this article set straight for me the differences between ArcSDE raster storage vs AGS Image Server & worthy of a whitepaper in the future.  

I do however have a couple of queries w.r.t performance (i'm pushing aside the pros/cons associated with each storage format - i think the paper does that relatively well), what i'm interested in is some statistics (or real-world experience) on performance w.r.t. ArcSDE raster catalogs/mosiacs vs AGS Image Services (both cached & uncached) both as separate services & as combined (e.g. using AGS Images services based upon both flat-file, data stored in ArcSDE gdb etc).  Moreover, is there published info or even knowlege that you or users can share w.r.t. what is the reccomended solution for maximum performance as i'm yet to see that presented.

I know there are a lot of influences when it comes to performance, however i'm sure there is real-world experience/guidelines or even formal inhouse test scenarios when it comes to architecturing a solution (re perf) rather than having to proof-of-concept the scenario's individually.  Look forward to hearing from you or others on what experience you can share.  brad
