For the past several years, customers have made use of a capability in Vista that allowed them to use a single app server to point to multiple Vista databases, either on the same database server, or on separate servers. This was useful as a low cost way, in certain, specific scenarios, to perform development and testing of Vista customizations.
Since that time, however, a number of architectural advancements needed to be made in Vista; advancements that would have created security issues if we were to continue allowing this option. Overall, we are in the process of modernizing our Vista codebase to split the Vista architecture from a monolithic setup, to a three-tier model with a client, app server, and database: client for data presentation and editing, app server for business logic, and database for storage only. As part of this process we need to use improved authentication between the app server and the database. As a result, only one database can be linked to a Vista installation, rather than multiple.
This means that customers need to stand up a complete, separate app server and database instance for each Vista environment they need. We realize that this has been an impact to our customer's long-held processes, and if it had been possible to securely modernize Vista without eliminating this option, we would have done so.
In our cloud, this means that each separate Vista database needs a separate environment in our cloud. To make this shift as minimally impactful as possible, we have created a more affordable "test only" pricing tier for customers to purchase test environment hosting in our cloud.
This architectural modernization in Vista has had a number of positive results, results that speak for themselves:
Over 50% aggregate increase in Vista workflow processing speed over the past 5 years
Single sign-on architecture and near-instantaneous document searching for the cloud (Coming Soon)
File System API (first REST-based web services API in Vista)
more to come!
64 bit architecture for client and server
Vista Remote Link (VRL) for improved access both on-premise and in our cloud
Much, much more
