Over the past few modules, we have actually unpacked the core elements that make up a system– the “what’s what” of architecture. Now it’s time to flip the script and have a look at the susceptabilities that lurk underneath the surface area. We’re discussing architectural dangers — the kinds of flaws that do not just create missteps yet can bring the entire procedure to a halt if overlooked.
Allow’s begin by highlighting several of the greatest transgressors:
- Single Points of Failing
- Bypass Controls
- Race Problems
We’ll go through each of these, break down what makes them dangerous, and– extra importantly– exactly how to reduce them. Let’s kick things off with the classic troubler: The Single Point of Failing
Solitary Factor of Failing– The “One Alarm Clock for Your Flight” Problem
Image this: you have actually got an early trip, and you depend on one alarm to wake you up. It’s your only line of protection in between you and a missed plane. If that a person clock stops working– power blackout, battery dies, cat knocks it off the table– you’re done. Video game over.
That’s exactly what a solitary point of failure (SPOF) remains in a system: one device, procedure, or component that whatever else depends on If it falls short, the whole system goes down with it.
