ArcGIS Server is a back-end server software component of ArcGIS Enterprise that makes your geographic information available to others in your organization and, optionally, anyone with an internet connection. This is accomplished through GIS services, which allow a server computer to receive and process requests for information sent by other devices.
To get started with ArcGIS Server, you’ll need to prepare your hardware, software, and data before you can begin publishing services. Then, you can use various types of applications to consume your services.
Configurations for ArcGIS Server
ArcGIS Server can be used in two ways. The primary way is as part of an ArcGIS Enterprise deployment in which ArcGIS Server is federated with an ArcGIS Enterprise portal. This is the deployment that most users should use. In this deployment, your geographic data is made available through layers and web maps in the portal. Those items can then be consumed in a variety of apps, including browser-based web apps and native apps on mobile devices, with little to no custom development required.
The other way is as a stand-alone deployment in which ArcGIS Server is not federated with an ArcGIS Enterprise portal. This was a common deployment in previous releases. This type of deployment should now only be used in limited circumstances. Stand-alone sites commonly use ArcGIS Server to provide foundational content and services as a data provider, with little to no security controls on the services. This allows users to provide their own apps to interact with the content. Users will typically have ArcGIS Enterprise or ArcGIS Online to use the data in the various applications.
ArcGIS Server sites using the stand-alone deployment can migrate to a federated ArcGIS Enterprise deployment. For complete information, see Migrating standalone ArcGIS Server to ArcGIS Enterprise.
Prepare hardware, software, and data
ArcGIS Server requires a machine capable of running a 64-bit operating system. The ArcGIS Server architecture is scalable, so you can add multiple machines if additional processing power is needed.
Depending on organizational requirements, you may need the help of your IT staff to allow your server to be accessed over the internet. When planning your hardware and environment, remember that ArcGIS Server can also be deployed on virtual machines or commercial cloud platforms such as Microsoft Azure and Amazon Web Services (AWS).
Once you install ArcGIS Server, you can use it right away, or you can integrate it with your organization’s existing web server by installing ArcGIS Web Adaptor. You also need to have ArcGIS Pro or ArcGIS Desktop installed on at least one computer in your organization to publish GIS services. This computer does not have to be the server.
The principal function of ArcGIS Pro is to publish and host GIS services. Services can be published to ArcGIS Enterprise in three ways:
- You share a web map, web layer, or other item from ArcGIS Pro to your ArcGIS Enterprise portal. As part of the sharing process, one or more GIS services are published to a federated ArcGIS Server site.
- You publish a GIS service directly from ArcGIS Pro to a stand-alone ArcGIS Server site (one that isn't federated with a portal).
- You upload a file, such as a CSV file or a zipped shapefile, into your portal and choose to publish a hosted feature layer.
When you share an item, such as a web map, mosaic dataset, or geoprocessing tool, from ArcGIS Pro to ArcGIS Enterprise, a wizard walks you through the process. The program alerts you to potential performance issues in the resource you are publishing. It also searches its list of registered data locations to find paths that need to be fixed after your resource is moved to the server.
During the publishing process, you'll enable capabilities that define the various ways your audience can use the service. For example, Feature Access is a capability that allows web users to edit vector features in a map service. Another example of a capability is WMS, which exposes your service through the Open Geospatial Consortium (OGC) Web Map Service (WMS) specifications.
Migrate services to the ArcGIS Pro service runtime
ArcGIS Enterprise 10.9.x, part of the ArcGIS 2021 releases, will be the last release of ArcGIS Enterprise to support services published from ArcMap. Beginning with the ArcGIS 2022 releases, it will no longer be possible to publish services from ArcMap (including ArcPy based in ArcMap) to ArcGIS Server sites. Esri highly recommends that all customers transition all publishing workflows to ArcGIS Pro at this time.
ArcGIS Enterprise 10.9.x will also be the last release series that will support running certain types of existing services originally published from ArcMap. Beginning with the ArcGIS 2022 releases, some services published from ArcMap will no longer be able to run if present during an upgrade. While many services that were originally published from ArcMap will continue to run on future releases, some specific service types must be reauthored and republished. This includes geoprocessing services and services that make use of SOEs or SOIs.
To prepare for this change, Esri recommends that customers consider migrating all existing services to using ArcGIS Pro.
Extend a service
If you find that your map or image service does not offer the functionality or business logic that you need, you can extend its base functionality with server object extensions (SOEs), or build custom operating logic with server object interceptors (SOIs).
These are advanced options and require custom development, but they can be deployed to the server or shared. No additional software is required to run an SOE or an SOI on ArcGIS Server.
SOEs and SOIs can be developed using Esri SDKs. Each offers tools, documentation, and samples for both .NET and Java.
To learn more about developing SOEs and SOIs, see Introduction to extending services.
Once you have GIS services running, you can use them in any app, device, or API that can communicate through HTTP. The following are examples:
- In ArcGIS Online and ArcGIS Enterprise, you can create and save maps and apps that display your services. You can use services that you publish, or add services from the web.
- When you share a map from ArcGIS Pro to your ArcGIS Enterprise portal as a web map, each layer in the map will be published to a federated ArcGIS Server site as a service.
- ArcGIS Pro can use GIS services published by ArcGIS Server. To begin, click the Add Data button in ArcGIS Pro.
- Any other app that can make a REST API service request can connect to ArcGIS Server. Supported clients range from smartphone and tablet apps that find the nearest grocery store to enterprise desktop applications for customer management or resource planning.
Maintain your server
As you work with your server over time, you’ll need to adjust settings, add and remove services, and set up security rules. ArcGIS Server Manager is a web application included with ArcGIS Server that provides an intuitive point-and-click interface for administering the server. You can use Manager to view the server logs, stop and start services, publish service definitions, define users and roles for security, and perform other similar tasks.
You may also want to perform server administration tasks automatically through scripting. ArcGIS Server has a REST administrator API that allows you to automate server management tasks using the scripting language of your choice. For example, you can write a Python script that checks the health of your services periodically and sends you an email if a service is detected to be down. This help system contains various server administration scripting examples.
