Getting Started with Databricks: Your First Steps

Okay, ready to jump in? Let's take some baby steps. Since we're trying to keep things W3Schools-style simple, we'll focus on the basics of getting set up and running your first notebook. This will provide you with a hands-on experience.

Sign Up for a Databricks Account: If you don't already have one, you'll need to create a Databricks account. You can sign up for a free trial or choose a paid plan depending on your needs. The free trial is a great way to get familiar with the platform without any initial financial commitment. During the signup process, you may be asked to provide some basic information and select the cloud provider you'll be using (AWS, Azure, or GCP). Once your account is set up, you'll gain access to the Databricks workspace.
Navigate to the Databricks Workspace: After logging in, you'll be taken to the Databricks workspace. This is the central hub where you'll create and manage your notebooks, clusters, and data. The workspace provides a user-friendly interface. The interface allows you to organize your projects and access various resources within the platform.
