The journey from writing code to deploying production-grade artificial intelligence has produced four distinct yet deeply connected engineering disciplines. DevOps gave the industry velocity. DevSecOps added security as a non-negotiable requirement. MLOps brought reproducibility to machine learning. DevMLOps—also called Secure MLOps—now combines all three into the only responsible way to ship AI systems under modern regulatory and threat landscapes.
This article presents a single, unified eight-stage model that reveals exactly what each evolution adds, followed by a comprehensive comparison and three production-ready horizontal diagrams.

DevOps to DevMLOps: A Summary and Comparison of Evolving Delivery Pipelines
In the fast-paced world of software and AI development, the way teams build, deploy, and maintain systems has undergone a profound transformation. What began as a push for speed with DevOps has evolved into more sophisticated paradigms like DevSecOps, MLOps, and now DevMLOps—each layering in critical elements of security, machine learning reproducibility, and governance. This article provides a concise summary of these technologies, detailing their stages, workflows, and practical implications. At its core, we'll compare their similarities and differences via a structured table, highlighting how they address modern challenges like rapid iteration, vulnerability management, and AI-specific risks such as model drift or adversarial attacks. Whether you're a developer transitioning to AI pipelines or a manager evaluating tools, this guide (expanded to ~1000 words) equips you with actionable insights for 2025 and beyond.
Summarizing the Technologies: From Speed to Secure Intelligence
DevOps: The Foundation of Automation
DevOps, coined around 2009, revolutionized software delivery by fostering collaboration between development (Dev) and operations (Ops) teams. Its core philosophy—"you build it, you run it"—eliminates silos through automation, enabling continuous integration/continuous delivery (CI/CD). Key stages include planning features, coding, building artifacts, testing, packaging (e.g., Docker images), releasing/deploying via strategies like blue-green deployments, operating in production, and monitoring for feedback loops. Tools like Jenkins, GitHub Actions, and Kubernetes power this, reducing deployment times from weeks to hours. However, traditional DevOps often overlooks security and scalability for non-traditional workloads like AI, leaving gaps in compliance and resilience. In 2025, it's the baseline for any digital transformation, but alone, it's insufficient for regulated or ML-heavy environments.
DevSecOps: Embedding Security from Day Zero
Building on DevOps, DevSecOps (Security added to the mix) emerged around 2016 as "Shift Left Security"—integrating security practices early to catch issues before they reach production. This proactive approach treats security as a shared responsibility, using automation to scan code, dependencies, and infrastructure. Stages mirror DevOps but infuse threat modeling in planning, static/dynamic application security testing (SAST/DAST) in code/build/test, software composition analysis (SCA) for vulnerabilities, and runtime protections like web application firewalls (WAF) or runtime application self-protection (RASP). Tools such as Snyk, Trivy, and Open Policy Agent (OPA) enforce policies via gates. The result? Faster, safer releases—critical in an era of rising cyber threats, where breaches cost enterprises an average of $4.45 million (per IBM's 2023 report, adjusted for inflation). DevSecOps shines in traditional apps but struggles with ML's unique artifacts like datasets and models.
MLOps: Operationalizing Machine Learning at Scale
MLOps adapts DevOps to the ML lifecycle, addressing the "last mile" problem where 87% of ML projects fail to reach production (Gartner, 2024). Introduced around 2018, it manages data, experiments, and models through reproducibility and automation. Stages extend DevOps: data ingestion/validation/versioning (e.g., with DVC), feature engineering, experiment tracking (MLflow or Weights & Biases), model training/evaluation, registry storage, deployment (e.g., shadow testing), serving/inference, and monitoring for data/concept drift—triggering retraining loops. Unlike code-centric DevOps, MLOps handles non-deterministic elements like hyperparameter tuning and A/B testing for models. Tools like Kubeflow and SageMaker enable this, making AI reliable for use cases like fraud detection. Yet, without security, MLOps risks poisoned data or stolen models, as seen in high-profile incidents like the 2024 Hugging Face breaches.
DevMLOps: The Secure, Governable Future of AI Operations
DevMLOps (or Secure MLOps) synthesizes DevSecOps and MLOps, emerging as the gold standard by 2025 for AI-driven enterprises. It ensures ML pipelines are not just fast and reproducible but also secure, compliant, and auditable—vital under regulations like the EU AI Act. Stages combine the above: threat modeling for data/models in planning, SAST/SCA on ML code/libraries, adversarial robustness/bias testing, model signing/SBOM generation, policy gates for compliance, and monitoring for attacks (e.g., prompt injection via tools like Lakera). Feedback loops include secure retraining with provenance tracking. This holistic approach mitigates AI-specific risks while scaling to agentic systems. Adoption is surging—McKinsey reports 60% of Fortune 500 firms piloting DevMLOps in 2025—driven by tools integrating all three (e.g., Vertex AI with built-in security).
These evolutions reflect a maturation: DevOps prioritizes velocity, DevSecOps adds guardrails, MLOps tackles ML chaos, and DevMLOps delivers trustworthy AI. Transitioning requires cultural shifts, tool investments, and metrics like deployment frequency or mean time to recovery (MTTR).
