Since version 2.0, Proxmox VE offers a high availability option for clusters based on the Corosync communication stack. Starting from the PVE v.6.0 Corosync v.3.x is in use (not compatible with the earlier PVE versions). Individual virtual servers can be configured for high availability, using the built-in ha-manager.
Rocket Software Universe and Unidata have limited ability to create web-based front-ends to Universe/UniData content. Since Rocket Software provides SQL access to its database products, a SQL-based product can be used to build a web-based UI to the databases; regardless of using Files or Tables in U2.
In 2004, 4D 2004 was the first version of 4D to allow developers to create standalone, client/server, web and Service Oriented Applications (SOA) without changing any code.

The two products have coexisted since then; however, SQL/DS was rebranded as "DB2 for VM and VSE" in the late 1990s. [5]
Azure SQL Database is built on the foundation of the SQL server database and therefore, kept in sync with the latest version [2] of it by using the common code base. Since the cloud version of the database technology strives to decouple it from the underlying computing infrastructure, it doesn't support some of the context specific T-SQL ...
