But increasingly, after some leading cloud providers such as Google Cloud having gained more traction and technology maturity, the terminology is becoming representative of sets of architecture, managed services, and highly scalable environments that define how we build solutions. For data engineering, that means building data products using collections of services, APIs, and trusting the underlying infrastructure of the cloud provider one hundred percent.

The difference between the cloud and non-cloud era

If we want to compare the cloud with the non-cloud era from a data engineering perspective, we will find that almost all the data engineering principles are the same. But from a technology...
