Usually, yes — if downtime matters to customers or operations, you should have some alerting, and the choice is typically:
- Slack for visibility and collaboration
- PagerDuty for urgent, action-required incidents
Practical rule
-
Use Slack if:
- the service is internal or low-criticality
- downtime can wait until business hours
- you mainly want the team informed
-
Use PagerDuty if:
- the service is customer-facing or revenue-critical
- you need an on-call person to respond quickly
- you have an SLA/SLO, or outages need escalation and tracking
Common setup
A lot of teams do both:
- PagerDuty sends the urgent page to the on-call responder
- Slack posts incident updates to a channel for broader visibility
If you’re unsure
A good default is:
- Slack for all alerts
- PagerDuty only for high-severity downtime
If you want, I can help you choose based on your app type, team size, and how fast someone needs to respond.
