Reliability and Resilience Reliability and resilience are the topics of this issue of LongEx Mainframe Quarterly. Often taken for granted in mainframe systems, the high standards of resilience and reliability required from mainframes don’t happen by accident
In our first management article, we take a step back, and look at the different levels of recovery that give us resilience in depth: how high reliability is achieved. By doing this, we see that offsite disaster recovery strategies are only one or many recovery layers.
In our opinion article, we argue that high availability and resilience come from solving not only the big problems, but all of them: big or small.
Finally in our second management article, we look at open source software. We revisit the arguments about whether open source software is a viable option, but from a mainframe perspective.
We hope you enjoy this issue.
