Databricks began as a research project at the University of California, Berkeley, with a simple goal: to help process large amounts of data more efficiently. The project was led by a team of researchers, including Matei Zaharia, Ali Ghodsi, Reynold Xin, Ion Stoica, and others at the AMPLab. They developed Apache Spark, a tool that drastically improved the speed and efficiency of big data processing. This focus on solving real data problems laid the foundation for what Databricks would eventually become.

As data volumes grew, so did the need for practical and scalable solutions. Recognizing this, the team officially launched Databricks as a company in 2013. They expanded its focus to include not just data processing but also data engineering and machine learning, making it an attractive option for businesses needing to manage, analyze, and derive insights from large datasets.

To further drive growth, Databricks strategically partnered with major cloud providers like AWS, Azure, and Google Cloud, simplifying integration for businesses. This move contributed to the company's rapid expansion. Today, Databricks is valued at over $43B billion, a testament to the founders’ vision of addressing real-world data challenges and their ability to adapt to the evolving needs of businesses.

Why Use Databricks?

Databricks is a powerful platform designed to help companies handle and analyze large amounts of data. From the start, its goal was to make it easier for organizations to process big data, whether for data engineering, machine learning, or analytics. By bringing all these tools together in one place, Databricks simplifies the process of cleaning, preparing, and analyzing data, allowing teams to work faster and make more informed decisions.

Core Components of Databricks

The Databricks platform is built around several core components that simplify and enhance data engineering, data science, and machine learning workflows:

1. Unified Data Analytics Platform It allows teams across data engineering, data science, and business analytics to collaborate in one platform. From digesting data to performing analysis and creating visualizations, this component simplifies workflows and enhances efficiency by bringing all necessary tools together in a single workspace.
2. Delta Lake Delta Lake ensures data reliability by supporting ACID transactions and scalable metadata management. It makes data lakes more dependable, allowing for consistent and accurate data processing even as datasets grow.
3. MLflow MLflow manages the entire machine learning process. It helps teams track experiments, organize models, and deploy them efficiently, streamlining the journey from model development to production.
4. Databricks SQL Databricks SQL enables users to run SQL queries on data stored in the data lake and create visualizations and dashboards. It provides an easy way to analyze data and generate insights that can be quickly shared across the organization.
5. Collaborative Notebooks Collaborative Notebooks support real-time collaboration by allowing team members to write and run code, visualize data, and work together in multiple programming languages within a single document. This feature helps streamline the development and refinement of data projects.
6. Security and Governance Security and Governance features protect data and ensure compliance with regulations. This includes user authentication, access control, data masking, and audit logging, all of which maintain the security and integrity of your data.

Databricks in action:

Databricks Architecture:

Databricks operates out of a control plane and a compute plane. The control plane includes the backend services that Databricks manages in your Databricks account. This includes the web application, compute orchestration, unity catalog, queries and code. The compute plane is where your data is processed, this can be a serverless compute resources running on databricks, or a classic compute resources running in the cloud provider.

Each Databricks workspace has an associated storage bucket known as the workspace storage bucket, which is inside your cloud provider for databricks.

Workspaces:

Workspaces in Databricks provide a collaborative environment for your teams to work together on data and analytics projects. Here’s how to manage them:

1. Workspace Organization: Organize your workspaces by project, team, or department. This makes it easier to manage resources and permissions effectively.
2. Shared Notebooks: Use shared notebooks for collaborative work allowing team members to collaborate on code, visualize data, and share insights in real time.
3. Version Control: Integrate your workspace with version control systems like Git to track changes, manage code versions, and collaborate more effectively. This is essential for maintaining the integrity of your projects and ensuring reproducibility.

Notebooks:

Notebooks are the primary tool in databricks for creating data science and machine learning workflows and collaborating with the team. Provide a real-time coauthoring in multiple language, versioning, and built-in data visualizations.

Cluster:

A Databricks cluster isa set of configurations and computation resources where you run data engineering, data science, and data analytics workloads.

You run these workloads as a set of commands in a notebook and databricks make a distinction between all-purpose clusters and job clusters. You use all-purpose clusters to analyze data collaboratively using interactive notebooks and job clusters to run fast and robust automated jobs.

Permissions:

Managing permissions is crucial for maintaining the security and integrity of your data. Here are some steps to consider:

1. Role-Based Access Control (RBAC): Implement RBAC to assign specific permissions to different roles within your organization. This ensures that users only have access to the necessary data and resources for their role.
2. Cluster Policies: Control the configurations and permissions of clusters to prevent unauthorized access and ensure that clusters are used efficiently.
3. Data Access Controls: Implement fine-grained access controls at the database, table, and column levels to protect sensitive data.
