Questions & Answers


For an enterprise, more than the initial setup cost, it is the ongoing maintenance cost that is minimized by offloading to a Cloud setup. The database or server maintenance is handled by the Cloud service vendors, and if one is using a hosted solution (likely to be offered by partner companies) even the Enterprise Architect repository maintenance and scheduled tasks can be offloaded.

More information on Enterprise Architect Cloud services can be found on the following page:

Yes. Here it is.

No. Version control in Enterprise Architect is entirely different to DB versions; you can configure AWS to take automated backups of the database, but this is not related to the version control settings of Enterprise Architect.

Server Software, Platform and Setup

This varies, but for the purposes of the demonstration, using the RDS and EC2 instance, the time involved is essentially that required to install the software (such as the Cloud service and MySQL ODBC connection).

Yes. Sparx Systems' Cloud services can be set up in other Cloud environments. This could be a publicly available Cloud environment such as Rackspace or Microsoft Azure, or an internal, private Cloud setup.

The approach of hosting the database should not be any different when compared to Windows or Linux servers, but the Sparx Systems' Cloud software is available only for a Windows based setup and thus might need some crossovers in Linux to make it work.

RDSs are dedicated, optimized DB nodes, where you do not have to worry about installing and maintaining a database engine. An EC2 instance, on the other hand, requires users to set up and maintain the databases as is done for a local server.

Enterprise Architect expects a 32-bit ODBC connection to the remote database. Even a 64-bit machine should have an ODBCAD32 in the SysWow64 folder.

Server Sizing and Performance

There is no simple answer to this question, as it depends on the individual needs of an organization. However, AWS offers a range of performance optimized / memory optimized nodes, with different configurations. The cost of use might also vary according to the selected setup. The storage space can also be paid for as per the use.

Enterprise Architect's repository performance for local servers will be better than the Cloud hosted repository. The Cloud repository is a value addition for users who connect to a remote database repository over WAN. Performance tests indicate that the Cloud connection is faster than remote WAN access.


Yes. The EC2 instance is like any other normal windows machine, and hence can be used to host the floating license server.

Yes, an RDS setup gives you access to a database and you can create any number of repositories on it, depending on the memory available.

There is a free use tier in AWS that can be used to try such a setup, but be aware that the free servers compromise on performance.

Yes. For AWS or any other Cloud services supplier.
