In today's world, cloud computing is not new; however, the sheer quantity and diversity of available data sources make it strikingly different from previous eras. The current glut in data requires a new set of tools to manage and analyze this unprecedented amount of information effectively. A modern data stack (MDS) is a set of cloud-native technologies for managing enormous and heterogeneous data sets, which can help CDOs demonstrate results quickly. Key components of an MDS include a fully managed ELT data pipeline, a data warehouse or lakehouse, data transformation tools, and data visualization platforms. By using an MDS, companies can uncover insights buried in large datasets and share them across different business units to drive growth and innovation.
