Cloud-based data warehouses offer unlimited scalability and combine the best features of traditional data warehouses and data lakes. They provide top-notch support for structured, relational data and semi-structured data like JSON and XML. Combining a data lake and data warehouse into a single system reduces complexity, latency, and storage costs while improving data governance and searchability. Modernizing your data warehouse by incorporating the key features of data lakes can result in a simpler system with lower end-to-end latency for less money.
