Which SLIs/SLOs are relevant for AWS CloudWatch?

AWS CloudWatch is a powerful monitoring tool that helps teams ensure their applications and infrastructure are performing optimally. When implementing Service Level Indicators (SLIs) and Service Level Objectives (SLOs), it's crucial to track relevant metrics for maintaining service health and performance.

Relevant SLIs for AWS CloudWatch

  • Latency: Measuring the time taken to respond to requests.
  • Availability: The percentage of time the service is operational and accessible.
  • Error Rate: The percentage of requests that result in an error.
  • Throughput: The number of requests processed over a period of time.
  • Resource Utilization: Metrics on CPU, memory, and other resource usage.

Example of SLO Implementation

For instance, an organization might set an SLO of 99.9% availability for their web application. Using CloudWatch, they can monitor the uptime and alert if availability drops below this threshold.

// Example SLO Monitor if ($availability < 99.9) { alert("SLO breached: Availability below 99.9%"); }
