Ozri Update: ArcGIS 10.1 – Understanding new concepts for Server

Ozri 2012 Update

ArcGIS for Server has been re-architected at 10.1 to work in 64-bit architectures and use a more cloud-friendly, web services-oriented design.

In our presentation this afternoon, Erik and I covered a few key highlights of new functionality in ArcGIS for Server at 10.1:


At 10.1, the following changes have been made in the ArcGIS for Server architecture:ArcGIS 10.1 for Server architecture

  • ArcGIS for Server runs exclusively as a native 64-bit application.
  • The SOM and SOC have been replaced with a single component, the GIS server.
  • ArcGIS for Server local (DCOM) connections are no longer supported. All communication with GIS services is through HTTP using SOAP or REST.
  • ArcGIS for Server can host services out of the box and does not require a web server on installation. You can optionally connect it to your own web server using a new component called Web Adapter.
  • The new REST-based ArcGIS Server Administrator API allows you to administer your ArcGIS Server site through scripting. With this API you can automate tasks such as creating a site, adding machines, publishing services, querying the logs, and starting and stopping services.

ArcGIS Server on Amazon Web Services

ArcGIS Server on Amazon Web ServicesAmazon Machine Images (AMI) that can be used to deploy ArcGIS for Server on Amazon Elastic Compute Cloud (EC2) are now available with the following operating systems and database management systems: for the Linux computing platform in addition to Windows. The new ArcGIS for Server architecture allows better support for cache creation and geoprocessing on Amazon EC2.

  • ArcGIS Server on Ubuntu Linux with PostgreSQL
  • ArcGIS Server on Windows with SQL Server Standard
  • ArcGIS Server on Windows with SQL Server Express

There is also a new application – ArcGIS Server Cloud Builder on Amazon Web Services—to deploy your ArcGIS Server on Amazon Web Services site, create templates, make backups of your sites, or delete sites.


You can publish services directly from ArcGIS for Desktop, and you now have the option to copy the relevant data to the server at the time you publish. This is especially helpful for distributed deployments or cloud deployments where you may not have permissions to directly log in to the server.

A new service definition file type (.sd) helps with this effort. It contains the complete definition of a GIS service. An SD file can be saved and copied between machines.

All map services are now required to use the optimised drawing engine for ArcGIS Server that was introduced as an option at 9.3.1.


ArcGIS 10.1 for Server is the last release to support ArcGIS Server Web ADF for Microsoft .NET and Java. As a result, the Web ADF Applications Manager has been moved to a separate installation. New web applications should be written as JavaScript, Flex, or Silverlight applications.

Additionally, ArcGIS for Server local (DCOM) connections to Web ADF applications are no longer supported, and Web ADF applications using non-pooled services are no longer supported. Exceptions are connections to pre-10.1 services.

Don’t forget that if you weren’t able to make today’s presentation, we’ll be presenting on ArcGIS for Server at 10.1 tomorrow afternoon at 2pm in the Hyde Park Room.
