As corporations merge and grow, often legacy systems need to be integrated and maintained. Over time this can lead to hundreds of separate applications, with a few key personnel kept from each merger in order to run those systems. These services could be in any language, following any protocol, and having them all work together is very difficult.
An ideal organization of IT departments involves having small teams of people ready to challenge any issue, a flexible workforce. However, to do this around hundreds of apps would need an IT department in the thousands, assuming that every single employee could code in every single language. This is clearly not feasible.
TRELLIS offers a simpler solution; an entity synchronisation layer which every service and system will communicate to and through. This eliminates many of the problems of updating or changing any particular system; rather than needing to hunt for every reference point throughout every app, users can simply update the link between the service and the synchronisation layer in complete confidence that no other services will be affected.
Having an entity sync layer can also help to impose language standards across your applications, freeing up employees to work on multiple apps with a reasonable degree of confidence. Old applications that do not meet the new standards can be neatly phased out, as their only contact with other systems is through the synchronisation layer. Clear documentation will also increase workforce flexibility, as it gives a starting point for any new team coming in to fix a problem to understand the application they are working in.
