Estimating Service Credits Usage for ArcGIS Online

Different user environments will use different amounts of service credits. For example, a public facing website that only uses ArcGIS Online services will use a different number of service credits than an internal website that uses a combination of ArcGIS for Server and ArcGIS Online services. Below are some specific scenarios to help you estimate service credit consumption for your environment.

Scenario 1—Public Facing Web Map Using Only ArcGIS Online Services

A web map has been embedded in a public facing website. The ArcGIS Online-based web map is composed of the following:

  • An ArcGIS Online basemap
  • An ArcGIS Online hosted point feature service. The point data is based on US cities data from Esri and is being used to label city names and configure pop-up menus within the web map.

The website is used anonymously by the public and is active everyday over the course of one month, 24 hours a day. The web map typically accesses one point feature per second.

Service Type Estimated Service Credits Used
ArcGIS Online basemap Doesn’t use service credits
ArcGIS Online hosted point feature service .23 GB of data transfer per month
Total estimated service credits used 17 per month
 

Scenario 2—Public Facing Web Map Using a Hybrid User Environment

A web map has been embedded in a public facing website. The ArcGIS Online-based web map is composed of the following:

  • An ArcGIS for Server supplied basemap deployed on-premises by the organization
  • An ArcGIS Online hosted line feature service. The feature service is based on US cities data from Esri and is being used to visualize, label, and configure pop-up menus for road closures.

The website is used anonymously by the public and is active everyday over the course of one month, 24 hours a day. Peak monthly usage occurs during events such as natural disasters, major construction, and hazardous road spills. During peak usage the web map typically accesses 10 features every .5 seconds. During normal usage the web map typically accesses one feature every 15 seconds.

Service Type Estimated Service Credit Used
ArcGIS for Server basemap Doesn’t use service credits
ArcGIS Online hosted line feature service peak usage 5.5 GB of data transfer per month
ArcGIS Online hosted line feature service normal usage .02 GB of data transfer per month
Total estimated service credits used 396 (peak usage)
1 (normal usage)
 

Scenario 3—Desktop Analysis with ArcGIS Online Data Export and Tiled Service

A group of 50 desktop GIS analysts are leveraging a hosted feature service for monthly reporting on sales territories. In this scenario the analyst exports county boundaries from an ArcGIS Online hosted feature service to perform analysis locally using their desktop GIS.

The analysts perform this type of work 8 hours a day during one week out of every month. The groups’ maximum download rate is about 100 counties per hour.

This workflow also leverages an ArcGIS Online hosted tile basemap, which is a custom basemap that consumes service credits (as opposed to an ArcGIS Online basemap hosted by Esri that doesn’t consume service credits). Each analyst uses this hosted tile basemap service within the desktop GIS for visualization of their analysis.

The ArcGIS Online tiled service is a street map (JPG format) that averages 40 KB per tile. Each analyst typically requests 3 tiles at a time with each pan. Users typically pan 120 times an hour.

As an organizational best practice they are also utilizing the local caching capability of the desktop GIS to minimize bandwidth consumption.

Service Type Estimated Service Credit Used
ArcGIS for Server basemap Doesn't consume service credits
ArcGIS Online hosted feature service 5.2 GB of data transfer per month
ArcGIS Online hosted tile service 27.5 GB of data transfer per month
(50 analysts x .55 GB)
Estimated service credits consumed 37 ( hosted feature service)
1,980 (hosted tile service)
Total estimated service credits used 2,017
 

Scenario 4—Parcel Publication Hosted Feature Service

A group of 50 desktop GIS users (editors) are using an on-premises geodatabase for land record management (parcel editing). The database administrator has synchronized an ArcGIS Online hosted feature service with the editing environment. The hosted feature service is used as a publishing environment and is leveraged by the organization’s public facing parcel viewer application. The parcel data is synchronized daily.

The website is used anonymously by the public and is active everyday over the course of one month, 24 hours a day. The web map typically accesses 100 parcels per minute.

Service Type Estimated Service Credit Used
ArcGIS Online hosted feature service 1.2 GB of data transfer per month
Total estimated service credits used 86
 

Notes

The above scenarios are based on these four datasets:

  • Cities (US national point data set) = .10 kb/feature
  • Highways (US national line data set) = .12 kb/feature
  • Counties (US national polygon data set) = 2.7 kb/feature
  • Maricopa County Parcels (County polygon data set) = .3 kb/feature

The following variables were used in simulating workflows:

  • How many hours per week is the feature/tile service being accessed 
  • How many days per week is the feature/tile service being accessed
  • How many weeks per month is the feature/tile service being accessed 
  • How often is a user accessing the feature/tile service
  • What is the average size of a feature accessed in the feature service
  • What is the average size and number of a tiles accessed in the tile service
