AWS DATA ENGINEER - 101

Data: It is an oil of the Machine Learning models. Everything that we do, such as large language models, or generative models, relies on a lot of good data.

What is a Data Engineer?

A data engineer plays a vital role in the data lifecycle. Data engineering is designing and building systems to collect, store, and analyze data at scale[1].

Data engineers do more than just gather, prepare, and transform data. Their responsibilities also include:

  • Security: Protecting data and ensuring compliance.
  • Management: Overseeing data workflows and processes.
  • Orchestration: Coordinating how data moves and is processed across different systems.
  • Architecture: Designing data systems and infrastructure.
  • Software Engineering: Creating and maintaining software solutions for data processing.
  • Operators: Managing operations to ensure reliability.
  • Methods, Tools, and Services: Using various technologies to improve data processes.
