1. Introduction & Overview
What is DataOps?
DataOps is a collaborative data management practice that applies Agile, DevOps, and lean manufacturing principles to the end-to-end data lifecycle. Its goal is to improve the speed, quality, and security of data analytics by fostering better communication, automation, and governance between data engineers, scientists, analysts, and operations teams.
History or Background
- 2014: Coined by Lenny Liebmann at the IBM Big Data and Analytics Hub.
- 2017–2019: Gained traction due to rising demand for real-time analytics, regulatory compliance (e.g., GDPR), and the adoption of cloud data platforms.
- Modern Era: Integrates with cloud-native architectures, CI/CD pipelines, and DevSecOps workflows.
Why is it Relevant in DevSecOps?
DataOps plays a critical role in DevSecOps by:
- Ensuring secure and compliant data handling across the software development lifecycle.
- Supporting automated testing, validation, and deployment of data pipelines.
- Enabling continuous monitoring and auditing of data access and usage.
- Aligning data governance policies with CI/CD and security controls.
2. Core Concepts & Terminology
Key Terms and Definitions
| Term | Definition |
|---|---|
| Data Pipeline | A series of processes that move and transform data from source to destination. |
| DataOps | A set of practices that combines DevOps, Agile, and data management. |
| Orchestration | Automated scheduling and coordination of data tasks. |
| Data Drift | Unexpected changes in data distribution or schema. |
| Data Observability | The ability to monitor the health, accuracy, and lineage of data pipelines. |
How It Fits into the DevSecOps Lifecycle
| DevSecOps Stage | DataOps Integration |
|---|---|
| Plan | Define data models, privacy policies, and risk assessments. |
| Develop | Use version control for data pipelines and transformations. |
| Build | Integrate tests for data quality and schema validation. |
| Test | Automate security, compliance, and unit testing of data flows. |
| Release | Use CI/CD to deploy pipelines with audit trails. |
| Operate | Monitor data SLAs, errors, and lineage. |
| Monitor | Trigger alerts on anomalies, unauthorized access, or breaches. |
3. Architecture & How It Works
Components of a DataOps Architecture
- Data Sources: Databases, APIs, IoT, logs, etc.
- Ingestion Layer: Tools like Apache NiFi, Kafka, or Fivetran.
- Storage & Lakehouse: AWS S3, Google BigQuery, Snowflake, Delta Lake.
- Transformation Layer: dbt, Apache Spark, Airflow.
- Testing & Validation: Great Expectations, Soda Core.
- Orchestration: Apache Airflow, Prefect, Dagster.
- CI/CD Integration: GitHub Actions, GitLab CI, Jenkins.
- Monitoring & Observability: Monte Carlo, Databand, Prometheus.
- Security & Compliance: Vault, Ranger, IAM policies, encryption.
Internal Workflow
- Code/Data commit triggers pipeline.
- CI/CD tools test and validate transformations.
- Pipelines deploy to staging → production.
- Monitoring agents track data quality and performance.
- Alerts/logs integrated into SIEM or DevSecOps dashboards.

| Secrets Mgmt | HashiCorp Vault | Secure API keys and credentials |
| Cloud | AWS/GCP/Azure | Scalable, serverless data ops |
| Containerization | Docker, Kubernetes | Deploy pipelines as microservices |
4. Installation & Getting Started
Basic Setup & Prerequisites
- Git, Python 3.x, Docker
- Cloud access (AWS/GCP preferred)
- DataOps stack tools (e.g., dbt, Airflow, Great Expectations)
Step-by-Step: DataOps with Airflow + dbt + Great Expectations
# Step 1: Clone starter repo
git clone https://github.com/example/dataops-starter-kit.git
cd dataops-starter-kit
# Step 2: Start Docker containers (Airflow + Postgres + DBT + GE)
docker-compose up -d
# Step 3: Run dbt transformation
cd dbt/
dbt run
# Step 4: Validate with Great Expectations
cd ../great_expectations/
great_expectations checkpoint run my_checkpoint
