This was another chapter on handling big data. This chapter dealt with the Azure Data Factory service, which is responsible for providing ETL services on Azure. Since it is a PaaS, it provides unlimited scalability, high availability, and easy-to-configure pipelines. Its integration with Azure DevOps and GitHub is also seamless. We also saw the features and benefits of using Azure Data Lake Gen2 storage for storing any kind of big data. It is a cost-effective, highly scalable, hierarchical data store for handling big data, with compatibility with Azure HDInsight, Databricks, and the Hadoop ecosystem.
