Microsoft OneLake, a component of the tech company's Fabric platform, is a logical storage layer designed to streamline and optimise data analytics. The Fabric platform itself offers a comprehensive suite of technologies, established to deliver analytics-as-a-service.
OneLake acts as the singular storage layer within Microsoft Fabric, centralising data storage and reducing organisational complications such as data duplication. The promise behind OneLake is one storage place, even across different branches of a company - hence its name.
The concept driving OneLake is to have one reservoir for data and as part of the Fabric ecosystem, it plays a crucial role in mitigating data management issues. With the ever-expanding nature of data, OneLake has been designed to serve as a unified data lake for an entire organisation, regardless of the domains and units.
The physical storage underpinning OneLake is Azure Data Lake Storage Gen2 (ADLS Gen2), where Microsoft Fabric's data elements are stored. This type of storage supports the automatic storage of computing engines' data, stores data in a single common open standard format - Delta Parquet, and can store various Fabric artifacts.
The structure and governance of Fabric are based on principles similar to Power BI. Consequently, OneLake uses a similar structure for organising its objects. There are specific structural items like Workspaces and Domains for separating Fabric elements within this logical layer, with the foundational storage taking place in ADLS Gen2.
The overall aim of OneLake's design is to reduce data duplication. To this end, entities like Shortcuts and OneCopy make data available in other domains, under the same tenant, without the need for copying.
Accessing OneLake can be done in several ways. For instance, the OneLake Data hub in the Fabric Portal lets you find items stored in OneLake. Microsoft has also incorporated access directly via Windows Explorer with a downloadable OneLake file explorer. Another way to access OneLake is through the use of a URI or its API.
Beyond access, OneLake also provides security measures. In a model dubbed OneSecurity, security settings applied in OneLake will be followed by all workloads using its data - reducing the need to implement identical security protocols in each workload.
In summary, OneLake is Microsoft's initiative to provide a unified, singular data lake storage solution. It incorporates advanced features for managing, accessing, and securing data to facilitate optimised analytics.
In our current age of data-driven decisions and applications, Microsoft Fabric's OneLake component presents a significant turning point. The need for a comprehensive understanding of this technology is now more critical than ever, particularly so for those in the field of data analytics or usage.
There are various training courses available to gain a deeper understanding of OneLake in Microsoft Fabric. These include:
Keep in mind that learning is most effective with a hands-on approach. Engage in demos, labs, or practical exercises of the above courses to understand the inner workings in a real-world environment. These courses offer more than just theory; they should provide an opportunity to implement what one learns in practice.
