Resilience beyond infrastructure
On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
show that resilience is about business processes, not only servers.
Planned topics
- Redundant servers do not help if the payment provider, ERP, or carrier API is down.
- Resilience means the business keeps doing its important things, possibly in a reduced way.
- Start from critical business processes (sell in store, take web orders, ship, refund) and ask what each depends on.
- Targets (recovery time, recovery point) come from the business impact, not from technology preference.

Check your understanding
