My team inherited a cluster of 4 Windows Server 2012 R2 machines running a legacy finance application. At a time only one instance of the application should be up and running as the active\/primary instance.<\/p>\n

The application is cluster-unaware<\/a> so we set it up with the Generic Application<\/a> type. Most days it works fine but about once or twice per month the EXE stops responding and no failover happens. Someone has to log in and kill it to trigger failover, which is just plain silly.<\/p>\n

I see that your AlwaysUp may be able to better manage the program. My question is, can your product work to control and maintain the supervision of these instances?<\/p>\n

Hi Andrei. <\/p>\n

Several of our corporate customers have deployed AlwaysUp in Windows clusters. They tell us that, despite having no specific features that target cluster management, AlwaysUp works very well in that context.<\/p>\n

In situations like yours where 100% uptime of a particular application is important, AlwaysUp adds an efficient line of defense — one that complements traditional multi-machine failover. Here’s how that works.<\/p>\n

Application resilience: AlwaysUp protects against application failures<\/h2>\n

AlwaysUp’s job is to ensure that your application is always running. If your application crashes, AlwaysUp will automatically restart it.<\/p>\n

But AlwaysUp provides much more than basic crash protection. It can operate proactively, rooting out problematic situations before they metastasize into full blown failures.<\/p>\n

For example, you can have AlwaysUp quickly recycle your application if it:<\/p>\n
