Building a Scalable AIOps Platform from Zero: A Guide for Small Teams

1. Overview: How Far Are We From the Ideal AIOps Kingdom?

We discuss the gap between current practices and the ideal AIOps state, focusing on three goals: eliminating blame, avoiding midnight incidents, and removing 24/7 on‑call duties.

We apply a 5W‑1H analysis to clarify what we do, where, when, and who is responsible for AIOps.

The path to the ideal involves coding: operations engineers must adopt development practices to build AIOps.

We reference the Kondratiev wave theory, suggesting a 50‑year cycle and positioning AI as the current driving force.

2. Preparation: Start with the End in Mind

Operations roles evolve from traditional ops to SRE, DevOps, and finally AI engineering. We define the three “horse‑power” components of AIOps: monitoring, alerting, and CI/CD platforms.

We compare first‑tier (BAT) and second‑tier (mid‑size) enterprises, emphasizing open‑source tools and the need for reliability and availability.

Availability depends on extending mean time between failures and reducing mean time to repair, achievable through automation and intelligence.

3. Launch: Building the AIOps Stage from Scratch

3.1 Data Ownership

Data is the foundation; without it, modeling and analysis are impossible.

3.2 Data Collection

We use open‑source and self‑developed collectors that ensure lossless, controllable ingestion and preprocessing, including log standardization.

3.3 Data Storage

Different storage strategies are applied for hot and time‑series data, supporting real‑time aggregation and accurate computation.

3.4 Alerting System

Alerting is integrated with the monitoring platform, allowing configurable thresholds and correlation.

3.5 CI/CD System

A robust CI/CD pipeline runs automated QA tests to ensure safe, high‑quality releases.

3.6 Online System

Collected data flows through real‑time queues, is processed, stored, queried, cached, and visualized, feeding back into alerting and automated remediation.

4. Explosion: Intelligent Decision‑Making

4.1 Modeling Algorithms

Statistical, proximity, and density‑based methods are used for anomaly detection; isolation forest achieves >90% accuracy.

4.2 Alert Aggregation

Aggregating related alerts reduces noise, allowing a single notification for cascading failures.

4.3 Root‑Cause Analysis

Decision‑tree and hierarchical analysis trace issues from symptoms back to underlying causes.

4.4 Prediction

Simple averaging, weighted moving averages, exponential smoothing, ARIMA, and LSTM models are employed for time‑series forecasting, with LSTM achieving the lowest error rates.
