Alation Delivers Governance for Insight in Data Lakes, Both On-Premises and in the Cloud

Alation has added new capabilities for cataloging data lakes deployed both on-premises and in the cloud, including data lakes built with Amazon Simple Storage Service (S3) and the Hadoop Distributed File System (HDFS).

The company’s latest release, Alation 5.0, delivers governed data within the data lake with greater transparency, enabling self-service analytics users to achieve more rapid return on investment through insight discovery.

As data lakes have become a standard, low-cost way to store data in the cloud and on-premises for many organizations, they have managed to push the cost of organizing data from the data creator to the data consumer, and along with this, navigating data lake complexity makes successful self-service analytics more difficult, said Venky Ganti, co-founder and chief technology officer, Alation. 

Alation addresses the complexity of working with data lakes with an enterprise data catalog designed to curate and share context throughout the enterprise.

Alation’s new native integration with file systems, including Amazon S3 and HDFS; integration with data processing engines such as Spark, Presto and Impala; and integration with data management products, such as the open source project Kylo and Trifacta Enterprise Wrangler, is aimed at providing a view into the full context of data stored in the data lake. This visibility into both the path the data traverses within the data lake and the data transformations made throughout the journey helps to consolidate technical and business context into a more easily digestible format for better insights.

According to Alation, by traversing the storage locations and lineage of data at every point of processing, it provides a single source of reference for data knowledge, no matter where data is physically stored whether in a file or database, on-premises or in the cloud, and Alation users get access to the critical relationships between raw data, transformed data and business context. This ability consolidates technical and business data knowledge in one place, and enables a more comprehensive, proactive approach to delivering trusted, governed data insights.
