How To Use Criticality Tiers for Great Good
Every outage feels like a crisis. Managers see KPIs at risk, engineers scramble to fix the issue, and DevOps respond to alerts, even when the part of the system causing the outage has truly little impact on the business.

But in most companies, nobody can clearly say how critical that service really is to the business. Aleksandr will show how adopting criticality tiers provides a simple, structured way to prioritize, build the right SLAs and put effort where it matters most.
