Let us begin with understanding of Azure what it is all about before moving to our Azure Databricks plugin and how it benefits our workload automation users.
“Azure is an open and flexible cloud platform that enables you to quickly build, deploy and manage applications across a global network of Microsoft-managed datacentres. You can build applications using any language, tool, or framework. And you can integrate your public cloud applications with your existing IT environment.”
Azure is incredibly flexible, and allows you to use multiple languages, frameworks, and tools to create the customised applications that you need. As a platform, it also allows you to scale applications up with unlimited servers and storage.
What is an Azure Databricks?
Azure Databricks provides the latest versions of Apache Spark and allows you to seamlessly integrate with open-source libraries. Spin up clusters and build quickly in a fully managed Apache Spark environment with the global scale and availability of Azure.
Azure Databricks is a data analytics platform optimized for the Microsoft Azure cloud services platform. Azure Databricks offers three environments for developing data intensive applications: Databricks SQL, Databricks Data Science & Engineering, and Databricks Machine Learning.
