Where do I start with a Cloud install?

When starting out with the installation of a Cloud Service it is recommended that you download and install the Cloud Service files and connect to a simple, non-ODBC Firebird repository. This is to ensure that the Cloud Service is operating before introducing other complexity involved with a DBMS connection.

This initial setup is demonstrated in our Introduction to Sparx Systems Cloud Services Webinar.

For more details on the process refer to the Cloud Based Repositories Help topic.

To access the Cloud Service do I need to alter the firewall on the server?

Yes, you need to set the server firewall to allow traffic on the port(s) that you set up in the Cloud Service. 

See the Firewall settings section of the Cloud Server Configuration Help topic.

Can I use Windows Active Directory on a Cloud Service?

Window Active Directory can be used with a Cloud Service via IIS if the machine hosting the IIS and the Cloud Service is registered in the Windows Domain.

See the Cloud Server using IIS (optional) Help topic, and the Import User IDs From Active Directory Help topic, in particular the Notes section.

Can the Cloud Service be hosted on the likes of Azure or Amazon Web Services?

The Sparx Systems Cloud Service can be installed on a web service provider such as AWS or Azure. It does require the platform to support a DBMS for the Model Repository, as well as a background Service.

Repository Overview

How do I transfer a repository to a Cloud Server DBMS?

For a standard migration of the content of one repository to another repository, where the repositories are a file or a DBMS repository, you should use Enterprise Architect's Project Data Transfer.

This will not operate when the connection to a repository is a Cloud Service HTTP connection. So, to perform a Project Transfer, you must set up a direct ODBC connection to the DBMS on the Cloud Server. This can be done on another workstation connected via ODBC to the Cloud DBMS, or you can temporarily install Enterprise Architect on the Cloud Server and run the Project Transfer process locally.

Can the Sparx Systems Cloud Service be run on Linux?

The Sparx Systems Cloud Service can be run on Linux.

For more details see standalone under Using Multiple Configurations in the Cloud Server Configuration Help topic.

What are the System Specifications for Cloud and Pro Cloud Services?

Both the Cloud Service and the Pro Cloud Service are very lean on CPU and RAM usage, so we do not provide any direct specification except that they are installed on a Windows or a Linux machine.

With the Cloud Service, for up to 50 concurrent users, we do recommend that you install it on the same server as the DBMS for efficiency.

For the Pro Cloud Service, as this is a Web based service, 500 users is not a large volume for handling the intermittent short requests. So we suggest you start with a single machine with the requirements to suit the DBMS.

In short, it is purely the DBMS machine specifications that you need to assess.  For that you will need to review the DBMS vendor's system requirements.

WebEA returns "Diagram Image not Found" - what does this mean?

This error indicates that the diagram exists in the model, but the image of the diagram has not been generated.

You can correct this by opening the model with Enterprise Architect (Build 1350 or later), and selecting the 'Batch create diagrams and/or Linked Documents cache' option.

You should also select the 'Auto create Diagram Image and Image Map (each time a Diagram is saved)' option to ensure the image is updated when you modify a diagram in Enterprise Architect.

For details, see the Configure Enterprise Architect model options section of the WebEA Installation and Configuration Help topic.

You can also run the EA Worker application on the Pro Cloud Service server to ensure that diagram images in WebEA are kept up to date (even if the 'Auto create Diagram Image' option is not used in Enterprise Architect).

For details, see the How to configure automatic viewable components Help topic.

Can I use Windows Active Directory with WebEA?

WebEA works through a web browser, hence it cannot support Windows Active Directory.

In the WebEA.config file there are a number of access options ranging from no required password through to requiring the username password in the repositories' security.

For details see the How to configure WebEA models Help topic.

What happens if my Pro Cloud license expires?

If the Pro Cloud license expires you will no longer be able to use WebEA to access your repository, nor will you be able to manage Visibility Levels within your model.  However, the Pro Cloud server will continue to operate as the standard Cloud server, so you will still be able to access your Cloud repositories via your licensed workstation installations.
