Layers of Databricks Architecture

  • Delta Lake: Delta Lake is a Storage Layer that helps Data Lakes be more reliable. Delta Lake integrates streaming and batch data processing while providing ACID (Atomicity, Consistency, Isolation, and Durability) transactions and scalable metadata handling. Furthermore, it is fully compatible with Apache Spark APIs and runs on top of your existing data lake.
  • Delta Engine: The Delta Engine is a query engine that is optimized for efficiently processing data stored in the Delta Lake.
  • It also has other inbuilt tools that support Data Science, BI Reporting, and MLOps.

All these components are integrated as one and can be accessed from a single ‘Workspace’ user interface (UI). This UI can also be hosted on the cloud of your choice.

Why Databricks Platform is a Big Deal?

After getting to know What is Databricks, you must know why it is claimed to be something big. Databricks platform is basically a combination of four open-source tools that provides the necessary service on the cloud. All these are wrapped together for accessing via a single SaaS interface. This results in a wholesome platform with a wide range of data capabilities.

  • ‍Cloud-native: Works fine on any prominent cloud provider
  • Data storage: Stores a broad range of data including structured, unstructured, and streaming
  • Governance and management: In-built security controls and governance
  • Data science tools: Production-ready data tooling from engineering to BI, AI, and ML

All these layers make a unified technology platform for a data scientist to work in his best environment. Databricks is a cloud-native service wrapper around all these core tools. It pacifies one of the biggest challenges called fragmentation. The enterprise-level data includes a lot of moving parts like environments, tools, pipelines, databases, APIs, lakes, warehouses. It is not enough to keep one part alone running smoothly but to create a coherent web of all integrated data capabilities. This makes the environment of data loading in one end and providing business insights in the other end successful.

Databricks provides a SaaS layer in the cloud which helps the data scientists to autonomously provision the tools and environments that they require to provide valuable insights. Using Databricks, a Data scientist can provision clusters as needed, launch compute on-demand, easily define environments, and integrate insights into product development.
