Sample Real-Time Web Applications
Demo
• If you have downloaded these slides and are viewing them on your own
computer, please view the slides in “Slide Show” mode. There are animations in
the slides that replicate demo-like workflows.
• Also, if you don’t view in slide show mode, many slides will appear cluttered an
unintuitive because all graphics will appear at once.
Agenda
• Learn how to
- make real-time data available to web applications
- configure web applications to use real-time data

Applying real-time analyticsGeoEvent Services
• A GeoEvent Service configures the flow of GeoEvents,
- The Filtering and GeoEvent Processing steps to perform,
- what input(s) to apply them to,
- and what output(s) to send the results to.
Applying real-time analyticsProcessing
You can create
your own
processors.
• You can perform continuous analytics on GeoEvents as they are received using a
processor.

Stream Services
Getting Real-Time data into Web Apps
• Feature layers pull from feature services
- Web apps poll to get periodic updates
- Must be backed by an enterprise geodatabase (EGDB)
• Stream layers subscribe to stream services
- Web apps subscribe to immediately receive data
- Low latency and high throughput
Send Features to a Stream Service
• Are discoverable via services directory
- http://<your server>/arcgis/rest/services/iss-stream/StreamServer
• Can be secured just like any other ArcGIS Server service using
- ArcGIS internal user store
- Active Directory/LDAP
- PKI
• Can be scaled using clustering
The foundation for real-time web apps
Stream Services
Enabling real-time web apps
Stream Layers
• Part of the ArcGIS API for JavaScript
• Subscribe to stream services
- immediately receive data
- low latency and high throughput
• Can filter on
- an area of interest
- field values
• Stream service communicate over a web socket
- Web socket protocol must be allowed on network
- Client must have a browser that supports web sockets

Publishing real-time data via stream services
Stream Services
• Created in GeoEvent Manager
GeoEvent Output
Stream Services
• Stream services are published from GeoEvent Manager
Publishing
Stream Services
• Can store latest event in
geodatabase
- One per track
• Provides operational
context for new
connections
• Requires a companion
feature service
Store Latest
Stream Services
• Stream service in ArcGIS Server Manager and services directory
• Just like map, geocode, GP, etc.
Discovery and Details
Stream Services
• Just like map, geocode, GP, etc.
