iTAC Software


iTAC started using Oracle GlassFish 2.1 in 2008. In time, the company started experiencing problems in some areas of the application server (e.g., security updates), with customers of iTAC requesting fixes. Unfortunately, the fixes were not available in GlassFish Open Source Edition. Considering the critical nature of iTAC’s product, the company decided to address the increasing risks.

Migrating to Oracle Glassfish 4.x meant that iTAC would be losing the commercial support optionsince Oracle decided to discontinue their support starting with that version. That’s when the company decided to switch – since January 2016, iTAC is running its TAC.MES.Suite in production on Payara Server.


iTAC was keen to use an open source application server;however, they also needed an option to use professional support – this was no longer available from Oracle. When reviewing other application servers and comparing them to Payara Server Enterprise, iTAC saw a huge gap in terms of other products’ compatibility between their open source and commercially supported versions, which was not the case for Payara Server Enterprise.

As long-term GlassFish users, iTAC appreciated the many similarities between Payara Server and GlassFish, making the migration process more straightforward. On top of that, iTAC was very satisfied with Payara Engineers’ high-level of Java EE expertise. Many of iTAC’s customers use the iTAC.MES.Suite, which is running on Payara Server Enterprise in high volume production environments. To satisfy compliance requirements, often mandated by OEMs, production equipment is typically tightly integrated into the MES infrastructure. As a result, the complete MES infrastructure must guarantee high availability, robustness, and high performance. iTAC’s SLAs guarantee 2-hour reaction time in case of a software issue; those requirements can be achieved now that Payara Enterprise is in place.


With Payara Enterprise, iTAC can now offer the application server to its customers under the name iTAC.AppServer. The great advantage for iTAC’s customers is that they no longer have to buy support for their application server from a separate provider. Instead, they can simply call iTAC support regardless of the root cause of a failure. All application server-related issues are then transferred to and resolved by the Payara’s engineers through iTAC’s Payara Enterprise contract.

iTAC must have all its customers under the same level of support and this can now be achieved with Payara Enterprise.

The key benefits of using Payara Enterprise for iTAC are:

  • Swift reaction time for support tickets raised
  • All issues resolved quickly and smoothly
  • The Customer Hub support portal is easy to use
  • iTAC is confident that they can get a quick resolution for potential bugs and issues in their production environment from support included with Payara Enterprise
