Mid-size scenario: modeled observability spend

For our mid-size SaaS reference (12 hosts, 45 GB/day logs), observability estimates range from $209/mo to $4,986/mo. Against $80k cloud spend, that is 0.3%–6.2%.

Mid-size SaaS

Growth-stage SaaS: 10 VMs, 1 Kubernetes cluster (50 pods), 15 services, 30-day retention, 25 users.

Result: Elastic Serverless from $209/mo to AWS CloudWatch at $4,986/mo — up to 96% ($4,777/mo) between cheapest and most expensive. Self-hosted AWS stacks include $2,500/mo SRE overhead.

Frequently asked questions

What percentage of cloud spend should observability be?
FinOps practitioners commonly target 5–10% of total cloud infrastructure for observability. Log-heavy platforms, full-fidelity APM, and long retention can push 15–25%. If observability exceeds 20% without matching reliability gains, audit telemetry volume before adding vendors.
How do I calculate observability as a percent of cloud spend?
Divide total monthly observability invoices (Datadog, Grafana, Splunk, etc. plus self-hosted infra attributed to monitoring) by total cloud compute + storage + network spend. Exclude unrelated SaaS. SignalCost helps model the observability numerator from telemetry inputs.
Why does observability grow faster than compute?
Log and trace volumes often scale super-linearly with microservices. Custom metrics accumulate with each deployment. Retention policies rarely keep pace with ingestion growth — a pattern FinOps teams call 'telemetry sprawl.'
What is a healthy observability budget for a mid-size SaaS?
If cloud infra is ~$80k/month, a 10% observability target is ~$8k/month. Our mid-size reference scenario models managed vendors from roughly $3k–$20k/month depending on vendor choice — use the table below to see where you land.
