Going From Data Lakes to Oceans

Data lakes are a popular solution for uniting insights from ALL the organization’s data sources. Federated Sources approach generates the same output with a fraction of the effort and cost. The main resource of the organization — data — is distributed, duplicated, and cannot be aggregated for global insights in a clean, unified manner. Google is investing in the direction of federated sources, with a caveat — only three-only services like BigQuery and Amazon's BigQuery. The data lake solution is to build a data lake, where it can be queried using a single query engine.
