Web GIS | How to get a portal
ArcGIS for Server ArcGIS Online
• Software - Portal for ArcGIS as part of
ArcGIS for Server- Releases 1-2 times per year- Upgraded manually (by organization)
- Organization controls SLA
• Core Web GIS functionality (visualization, smart mapping, analysis…)
• Enterprise Integration- Web SSO via SAML- Web-tier Authentication via Web
Adaptor- Enterprise Groups- ArcGIS Server Integration…
• Advanced GIS functionality
• SaaS- www.arcgis.com- Releases 3-4 times per year- Upgraded automatically (by Esri)
- Esri controls SLA
• Core Web GIS functionality (visualization, smart mapping, analysis…)
• Enterprise Integration- Web SSO via SAML
• Esri-provided content and services- Basemaps- Living Atlas- GeoEnrichment, Routing, …
