What is Site Reliability Intelligence?

Site Reliability Intelligence (SRI) is the next evolution of Site Reliability Engineering (SRE). It’s an AI-native approach to infrastructure reliability that combines autonomous agents, deep system understanding, and continuous learning to predict, prevent, and safely fix failures before they impact customers.
In Simple Terms: If traditional SRE is about having skilled engineers watch and fix your infrastructure, SRI is about having an AI-powered second brain that never sleeps, never forgets, and gets smarter with every incident.

​

  • Autonomous operations
  • Proactive prevention at scale
This documentation describes the complete SRI vision , including features under development.

​
The Problem with Traditional SRE

Traditional Site Reliability Engineering faces increasing challenges:

Alert Fatigue

SREs drown in thousands of alerts daily. Most are noise, a few are critical - but which ones?

Manual Toil

Repetitive troubleshooting and remediation tasks consume 40-60% of SRE time

Knowledge Loss

When engineers leave, their tribal knowledge disappears. New incidents repeat old patterns.

Scaling Limits

You can’t hire SREs fast enough to match infrastructure growth. The ratio is broken.

​
How SRI Solves This

Site Reliability Intelligence introduces autonomous, intelligent systems that work alongside your SRE team:

​
The OPEL Loop

RubixKube implements SRI through the OPEL loop - a continuous cycle that mimics and augments expert SRE thinking:

Observe

​
Continuous Infrastructure Mapping - Available Now

  • Maps your entire infrastructure (Kubernetes, cloud, code)
  • Integrates with existing tools (Prometheus, Loki, Grafana)
  • Understands context, not just metrics
  • Tracks changes (deploys, configs, scaling events)

Plan

​
AI Agent Mesh Reasoning - Available Now

  • Multiple specialized AI agents analyze the situation
  • Agents reason over live data AND historical patterns
  • Propose safe, auditable remediation actions
  • Calculate blast radius and risk

Execute

​
Controlled, Safe Remediation - **Coming Q1 2026 **

  • Execute fixes behind safety guardrails
  • Approve PRs or apply controlled changes
  • Policy checks before any action
  • Rollback capability built-in

Learn

​
Evolving Intelligence - Available Now

  • Every incident updates the Memory Engine
  • RCAs become institutional knowledge
  • Playbooks refine automatically
  • Pattern recognition improves over time
Beta Status: RubixKube currently excels at Observe, Plan, and Learn (detection, analysis, knowledge building). The Execute phase (autonomous remediation) is coming in the next release. You can manually apply suggested fixes today.

SRI doesn’t replace SREs - it amplifies them. Your engineers focus on high-value work while SRI handles repetitive toil.

​
Real-World Benefits

​
Time Savings

MTTR Reduction

Before: 45 minutes average time to recovery
With SRI: 8 minutes average time to recovery
Savings: 82% faster incident resolution

Toil Elimination

Before: 40% of SRE time on repetitive tasks
With SRI: 10% of time on toil
Result: 30% more time for strategic work

​
Business Impact

​
Downtime = Lost Revenue

For a service generating $1M/hour:
  • 1 hour outage = $1M lost
  • SRI catches issues in minutes, not hours
  • Average savings: $800K per prevented major incident

​
Reliability = Retention

  • 40% of users abandon apps after one crash
  • SRI prevents customer-visible failures
  • Maintains SLOs consistently (99.9%+ uptime)

​
Happy SREs = Better Results

  • Reduced on-call burden (50% fewer pages)
  • Less burnout, higher retention
  • Teams ship features faster with confidence

​
Who Needs SRI?

Site Reliability Intelligence is essential for:

E-commerce Platforms

Downtime directly impacts revenue. Every minute counts during peak sales.

Financial Services

Compliance requirements + zero downtime tolerance. SRI provides audit trails.

SaaS Companies

Customer retention depends on reliability. SRI maintains SLOs at scale.

Healthcare Tech

Lives depend on uptime. SRI ensures critical systems stay available.

Gaming Platforms

User experience degrades instantly. SRI prevents lag and crashes.

IoT & Edge

Distributed infrastructure at massive scale. SRI manages complexity.

​
Core Principles of SRI

​
1. Proactive, Not Reactive

Traditional SRE reacts to incidents.
SRI predicts and prevents them.
  • Detect risky deployments before they cause outages
  • Identify configuration drift early
  • Spot resource exhaustion trends
  • Flag anomalous patterns before they cascade

​
2. Evidence-Based Decisions

Every action is backed by:
  • Logs - What the system said
  • Metrics - What the numbers show
  • Traces - How requests flowed
  • Events - What changed and when
  • History - Similar incidents in the past
No guesswork. No hunches. Just evidence.

​
3. Safe Autonomy

Autonomous doesn’t mean reckless:

Blast Radius Limits

Actions are scoped - never cluster-wide unless approved

Human-in-the-Loop

High-risk actions require explicit approval

Dry-Run First

Simulate changes before applying them

Instant Rollback

Every change is reversible

​
4. Continuous Learning

The system gets smarter every day: 
Incident Happens → RCA Generated → Fix Applied → 
Memory Updated → Future Incidents Faster → Patterns Recognized → 
Prevention Improves → Fewer Incidents Over Time
This is the virtuous cycle of SRI.

SRI in Action: A Real Scenario

​
Before SRI (Traditional):

  1. ⏰ ** 12:03 AM** - PagerDuty alert: “Checkout service down” 2.** 12:05 AM** - On-call engineer wakes up, logs in 3.** 12:10 AM** - Starts investigation (logs, metrics, traces) 4.** 12:25 AM** - Identifies issue: OOMKilled pod 5.** 12:35 AM** - Increases memory limits, redeploys 6.** 12:45 AM** - Service recovered 7.Next day - Writes postmortem (if there’s time)
Total downtime: 42 minutes ** ** Total downtime: 42 minutes (for $100K/hour service)

​
Engineer sleep lost: Entire night

​
With SRI (RubixKube):

1.** 12:03 AM** - RubixKube detects anomaly (pod OOMKilled) 2.** 12:03:10 AM** - RCA Pipeline identifies root cause instantly 3.** 12:03:15 AM** - Proposes fix: increase memory 512Mi → 1Gi 4.** 12:03:20 AM** - Auto-applies fix (within guardrails) 5.** 12:04 AM** - Service recovered, customers unaffected 6.** 12:04 AM** - RCA report generated automatically 7.** 12:04 AM** - Pattern stored in Memory Engine 8.Engineer - Sleeps soundly, reviews RCA in morning

​
Total downtime: 1 minute Revenue saved: 68,000+∗∗∗∗Revenuesaved:68,000+** **Revenue saved: 68,000+ Revenue saved: $68,000+ Future similar incidents: Prevented entirely

Observe → Plan → Execute → Learn creates a virtuous cycle where the system gets better over time.
Autonomous doesn’t mean uncontrolled. Guardrails, approvals, and blast radius limits ensure safe operations.
Every decision is backed by logs, metrics, traces, and historical patterns - never speculation.
The Memory Engine ensures institutional knowledge grows continuously, even as team members change.
