What is Databricks?
Let us start by answering this main question of What is Databricks. Databricks, developed by the creators of Apache Spark, is a Web-based platform, which is also a one-stop product for all Data requirements, like Storage and Analysis. It can derive insights using SparkSQL, provide active connections to visualization tools such as Power BI, Qlikview, and Tableau, and build Predictive Models using SparkML. Databricks also can create interactive displays, text, and code tangibly. Databricks is an alternative to the MapReduce system.
Databricks is integrated with Microsoft Azure, Amazon Web Services, and Google Cloud Platform, making it easy for businesses to manage a colossal amount of data and carry out Machine Learning tasks.
It deciphers the complexities of processing data for data scientists and engineers, which allows them to develop ML applications using R, Scala, Python, or SQL interfaces in Apache Spark. Organizations collect large amounts of data either in data warehouses or data lakes. According to requirements, data is often moved between them at a high frequency which is complicated, expensive, and non-collaborative.
However, Databricks simplifies Big Data Analytics by incorporating a LakeHouse architecture that provides data warehousing capabilities to a data lake. As a result, it eliminates unwanted data silos created while pushing data into data lakes or multiple data warehouses. It also provides data teams with a single source of the data by leveraging LakeHouse architecture.

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.

Step 2: After starting the trial subscription, you will receive a link from the Databricks menu item in Google Cloud Platform. This is to manage setup on the Databricks hosted account management page.
Step 3: After this step, you must create a Workspace which is the environment in Databricks to access your assets. For this, you need an external Databricks Web Application (Control plane).
It is required to ensure this distinction as your data always resides in your cloud account in the data plane and in your own data sources, not the control plane — so you maintain control and ownership of your data.
Step 5: Next to create a table in the Delta Lake, you can either upload a file, or connect to supported data sources, or use a partner integration.
Step 6: Then to analyze your data you must create a ‘Cluster‘. A Databricks Cluster is a combination of computation resources and configurations on which you can run jobs and notebooks. Some of the workloads that you can run on a Databricks Cluster include Streaming Analytics, ETL Pipelines, Machine Learning, and Ad-hoc analytics.
Step 7: In these Databricks, the runtime of the cluster is based on Apache Spark. Most of the tools in Databricks are based on open source technologies and libraries such as Delta Lake and MLflow.

Role-based Databricks adoption
In this context of understanding what is databricks, it is also really important to identify the role-based databricks adoption.
Data Analyst/Business analyst
For a Business analyst, visualization plays a pivotal role. So it requires a BI integration and also Databricks SQL is required.
Data Scientists are mainly responsible for sourcing data, a skill grossly neglected in the face of modern ML algorithms. They must also build predictive models, manage model deployment, and model lifecycle.
Data Engineers are mainly responsible for building ETL’s and managing the constant flow of data. They have to process, clean, and quality checks the data before pushing it to operational tables. Model deployment and platform support are other responsibilities entrusted to data engineers.
Databricks have to be combined either with Azure/AWS/GCP and due to its relatively higher costs, adoption of it in small/medium startups is quite low in India.
