What Is Critical Service
A critical service is any system or application essential for business operations. If it fails, it causes major disruption or financial loss.
Why Is Critical Service Important
Identifying critical services helps teams focus monitoring and response efforts where downtime would hurt most. This protects revenue and reputation.
Example Of Critical Service
A payment gateway for an e-commerce site is a critical service. If it goes down, customers can't buy products.

- List all services and map their dependencies
- Assess the business impact if each service fails
- Tag critical services in monitoring and alerting tools
