The short version

  • Only Docker has a free tier, so it costs nothing to try first.
  • Each has a real cost: Docker shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation; PagerDuty aIOps, status pages, and live call routing are expensive add-ons not included in base plans, significantly increasing total cost
  • They diverge on capability: Docker covers Container runtime, PagerDuty covers Incident response.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Docker

  • Shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation
  • Daemon socket exposure grants full root access to the host if compromised
  • Requires careful secrets management - credentials embedded in images or environment variables are easily harvested by attackers
  • Resource management complexity - misbehaving or compromised containers can consume all resources causing denial of service
  • Orchestration complexity - Docker Swarm is less capable than Kubernetes, requiring external tools for production deployments

PagerDuty

  • AIOps, status pages, and live call routing are expensive add-ons not included in base plans, significantly increasing total cost
  • Complex escalation policies require workarounds for scheduling patterns beyond basic weekly rotations
  • 5-user minimum requirement forces costs even for small teams, with forced Business tier upgrades adding $12,000+ annually for larger teams

PagerDuty integrates with 750+ monitoring, ticketing, and collaboration tools including Datadog, Slack, Jira, ServiceNow, New Relic, and Nagios.

Source
Docker: What are the main security concerns with Docker?

Key security risks include container breakout vulnerabilities through shared kernel exploits, daemon socket exposure that grants root access if compromised, weak isolation between containers, and credential leakage if secrets are embedded in images.

Source
PagerDuty: How much does AIOps cost in PagerDuty?

AIOps Intelligence is sold separately as an add-on starting at $699 per month, and is not included in any of the base plans.

Source
