Single Points of Failure to Eliminate
A single point of failure (SPOF) is any one component whose loss takes down the whole system. Resilient design is largely the work of finding these weak links and removing them before they cause an outage.
This article explains how we hunt down single points of failure in the systems we build and run.
Common Single Points of Failure
They hide in obvious and not-so-obvious places.
- A single server with no standby.
- One database with no replica.
- A sole administrator who holds all the access.
- One internet connection or power feed.
- A backup stored only in one place.
How We Remove Them
For each weak link we add redundancy, automation or documented alternatives, so no single failure can take the whole operation offline.
Frequently Asked Questions
Can every single point of failure be removed?
Not always economically, but we identify them all so you can decide which are worth the cost of eliminating.
