In our last blog post<\/a>, we talked about running ArcGIS Enterprise in the cloud. Now, let\u2019s take a look at a specific example of using cloud-native functionality to improve an existing workflow: tile caching.<\/p>\n

Caching map and image services is a time-honored approach to improving performance for basemaps and other map layers where the underlying data changes infrequently. We have multiple options today for how to cache our data. Raster tile caches are the traditional option, going back for over a decade; more recently, we introduced the vector tile cache option.<\/p>\n

We recommend that when possible, you should cache vector data (point, line and polygons) using vector tiles and cache raster data (imagery or hillshades) using raster tiles. However, you cannot migrate your vector data-based services and apps to vector tiles overnight, so let\u2019s focus on the traditional raster tile cache, which can be used with both map and image services.<\/p>\n"},{"acf_fc_layout":"content","content":"

By creating a raster tile cache, you pre-generate or \u201cpre-cook\u201d all of the images for a given area (extent) and scale. Map caches that cover large areas at large scales (zoomed in very close to the ground) can become big very quickly, easily going into tens or hundreds of gigabytes. For organizations with several global cached basemaps, it\u2019s not uncommon to have terabytes worth of map caches.<\/p>\n

So, how do we store all this data? Traditionally, data like this would be stored on a file server or a dedicated NAS device. But NAS devices can often be expensive to purchase and require ongoing maintenance. By comparison, cloud-native storage often costs less than USD $0.02 \u2013 $0.03 per gigabyte per month, and the underlying storage is fully managed with no need for scaling out hardware or tuning as storage demands increase or fluctuate.<\/p>\n"},{"acf_fc_layout":"content","content":"

Cloud storage support in ArcGIS Enterprise<\/h2>\n

ArcGIS Enterprise has supported cloud storage for map and image caches for several releases:<\/p>\n
