Tutorial: Building Secure Data Pipelines with SDLC/DevSecOps on AWS, Azure, and Google Cloud
In this tutorial, we'll explore how to build secure data pipelines on AWS, Microsoft Azure, and Google Cloud using principles of Secure Development Lifecycle (SDLC) and DevSecOps. We'll discuss the architecture and tools available on each cloud platform, and how to integrate security into every stage of your data pipeline.
1. Understanding the Data Pipeline Components
A data pipeline typically consists of several key stages:
