Monitoring Overview in AWS¶

Why is monitoring important¶

• We know how to deploy applications
  • Safely
  • Automatically
  • Using IaC
  • Leveraging best AWS components
• Our applications are deployed, and our users don't care how we did it.
• Our users only care that the application is working
  • Application latency: will it increase over time?
  • Application outages: customer experience should not be degraded
  • Users contacting the IT department or complaining is not a good outcome
  • Troubleshooting and remediation
• Internal monitoring
  • Can we prevent issues before they happen?
  • Performance and cost
  • Trends (scalling patterns)
  • Learning and improvement
