Teradata is highly stable. The workload management and software maturity provide a reliable system, unlike some newer cloud software that can exhibit misbehavior.

I don't think there is another system in the world as stable as Teradata. They have a redundant hardware setup with double components for everything. If one component fails, another one takes over. This redundancy extends to the data side as well. The system runs on multiple disks, so if one disk fails, the data is still available on another disk, and the replacement process is seamless thanks to hot-swappable components. We don't have to shut down the entire system to replace most parts in the Teradata system. We can simply slide out the faulty component and slide in a new one. Unlike old technologies that required powering down the entire system, Teradata's architecture allows for most operations to remain functional even during maintenance. However, in certain cases, depending on the architecture, we might need to power down the systems.

The stability is excellent except for Unity. That time when Unity was installed, if it was running on passive routing, it was fine; however, if you're running on active, there was still some problem with the software. We've tried to put it on active routing every time we experience major problems with the software. When that happens, we must go back to passive routing again. When I spoke to someone the other day, they said there's a new app now. They're going to shut down Unity. There's some other application they're going to install now. They're not going to continue with Unity anymore, and that's not being sold to clients anywhere worldwide. However, there was definitely a bug in the software. As we were installing Unity, there were always coming new releases out, and we had to upgrade, and even with the upgrades, it still gave us problems. It became better, yet it wasn't ever 100% successful.

Otherwise, with the other systems, for all our other clients, the 12 years I worked for them, I had maybe eight or nine P1 calls, meaning that the system was down. The system is very stable, except when we started to fill Unity for the bank. Then we had a lot of P1 calls caused by Unity.

In terms of stability, Teradata is stable. All legacy systems are quite stable and do not have that much downtime, probably because no one would work with a system that is not stable.
