Corepoint

• We have not had any issues with stability. 99.9% up time with production. We run assured availability with multiple servers. Only downtime is for upgrades (usually less than an hour).
• In the eight years we’ve depended on the Corepoint interface Engine, I can only remember failing over to our Backup Engine on two occasions. Both were handled gracefully by the Corepoint Assured Availability solution (A2). Neither incident was due to a problem with the engine itself, but were network interruptions due to external factors.
• Without an unlimited option, there’s always the question…should we be using the interface engine or stick with point-to-point in order to save on a connection license.

Cloverleaf

• I’ve never seen systems as solid as these.
• Incredibly stable. In 10 years I have never filled-out a TIR (Technical Incident Report) that was Cloverleaf-related. Not once. That’s a pretty big endorsement. Scalability is second to none as well.
• Alerting could be better
• Important: stability and reliability are excellent.
  Improvement: fully support more than two nodes in any interface path.

Rhapsody

• The last two upgrade versions have memory leaks.
• Orion, InterSysems, and CorePoint all said that we could run our entire enterprise on one server … we now have 10 production instances and are processing over 21 million transactions per day …
• Uptime rates, and configuration management are very good. Single file exports/backups allow for very light effort to replicate environments or to upgrade servers or Engine software.

Mirth

• We are adding interfaces on a weekly basis, very scalable.
• Does not scale well
• We only have to tweak or adjust interfaces a few times per year. This seems acceptable.

Ensemble

• It is very stable and scaling up is very easy. Creating a mirror for disaster recovery is very easy and requires very little work.
• We routinely re-start the engine, but otherwise it has never shut down. So far the engine itself is indestructible.
• After 7 years we had to increase the CPU processing and the RAM to accommodate scaling up of the numbers of interfaces. Otherwise the engine has been stable and reliable.
• It works, I feel confident in its stability.
