- 3. Introduction to Azure Data Engineering • Azure Data Engineering refers to the set of services and tools provided by Microsoft Azure for designing, implementing, and managing data solutions in the cloud. It encompasses various technologies and capabilities that allow organizations to process, store, and analyze large volumes of data efficiently. Whether dealing with structured or unstructured data, Azure Data Engineering provides a comprehensive suite of services to meet diverse business needs. • As an Azure data engineer, you help stakeholders understand the data through exploration, and build and maintain secure and compliant data processing pipelines by using different tools and techniques. You use various Azure data services and frameworks to store and produce cleansed and enhanced datasets for analysis.

It allows data engineers and data scientists to work together on large-scale dataprocessingandmachine learningtasks. 8. Azure HDInsight: A fullymanagedcloudservice thatmakesiteasytoprocesslarge amountsof datausingpopularopen-source frameworkssuchasHadoop, Spark, Hive, HBase, andmore. 9. Azure Stream Analytics: A real-time analytics service that ingests, processes, and analyzes streaming data from various sources. It provides insights into trends and patterns as data is generated. 10. Azure Data Explorer:A fast andhighly scalable service designedforanalyzinglarge volumesof datainreal-time.Itisparticularly well-suitedforlogandtelemetry data. 11. Azure Cache for Redis: A fully managed, open-source, and in-memory data store service that provides sub-millisecond response times. It is commonly used for caching and accelerating data access. 12. Azure Data Box: A family of devices designed to facilitate the secure and efficient transfer of large amounts of data to and from Azure. This is particularly useful for organizations dealing with massive datasets. 13. Azure Data Share: A service that enables organizations to securely share data with other organizations in a governed and compliant manner. It simplifies the process of sharing data across Azure subscriptions andwithexternal partners. 14. Azure Data Catalog: A fully managed service that serves as a centralized repository for discovering, understanding, and managing data assets across an organization. It helps in maintaining a data catalogfor betterdatagovernance
- 5. Azure Data Factory • Azure Data Factory (ADF) is a cloud-based data integration service provided by Microsoft Azure. It allows organizations to create, schedule, and manage data pipelines that can move data between supported on- premises and cloud-based data stores. Azure Data Factory simplifies the process of orchestrating and automating the movement and transformation of data, making it a fundamental component in modern data engineering workflows. • Azure Data Factory is Azure's cloud ETL service for scale-out serverless data integration and data transformation. It offers a code-free UI for intuitive authoring and single-pane-of-glass monitoring and management. You can also lift and shift existing SSIS packages to Azure and run them with full compatibility in ADF. • Azure Data Factory is a cloud-based data integration service provided by Microsoft. It allows you to create, schedule, and manage data pipelines that can move and transform data from various sources to different destinations.
- 6. Azure Databricks • Azure Databricks is a cloud-based big data analytics platform provided by Microsoft in collaboration with Databricks. It is built on Apache Spark and designed for data engineering, data science, and machine learning. Azure Databricks simplifies the process of building and managing Apache Spark- based big data and machine learning solutions by providing an integrated, collaborative environment for data scientists, data engineers, and business analysts. • Azure Databricks is a fully managed first-party service that enables an open data lakehouse in Azure. With a lakehouse built on top of an open data lake, quickly light up a variety of analytical workloads while allowing for common governance across your entire data estate. • Databricks is an industry-leading, cloud-based data engineering tool used for processing and transforming massive quantities of data and exploring the data through machine learning models. Recently added to Azure, it's the latest big data tool for the Microsoft cloud
- 7. Azure Synapse Analytics: Azure Synapse Analytics, formerly known as Azure SQL Data Warehouse, is a cloud-based analytics service provided by Microsoft Azure. It is designed to enable organizations to analyze and query large volumes of data with high performance and scalability. Azure Synapse Analytics integrates both data warehousing and big data analytics capabilities, providing a unified platform for processing and analyzing diverse datasets. Azure Data Lake Storage: Azure Data Lake Storage (ADLS) is a scalable and secure cloud-based data lake solution provided by Microsoft Azure. It is designed to handle large volumes of data for big data analytics and data science applications. Azure Data Lake Storage is built to support both structured and unstructured data, allowing organizations to store and analyze diverse datasets with high throughput and low-latency access. Real-time Data Processing with Azure Stream Analytics: Azure Stream Analytics is a real-time analytics service provided by Microsoft Azure that allows organizations to process and analyze streaming data in real-time. It enables the extraction of insights and actionable information from continuous streams of data generated by various sources, such as IoT devices, social media, applications, and more. Azure Stream Analytics supports a wide range of scenarios, including real-time monitoring, anomaly detection, and event-driven applications
- 8. Integration with Power BI 1.ConfigurePower BI Output inAzure StreamAnalytics: In theAzure StreamAnalytics job definition, users can configure Power BI as an outputsink. This is done by specifying the Power BI outputsettings, includingthe Power BI workspace, dataset, and table to which the streaming data will be sent. 2.Define Query Logic: Users define the query logic in Azure StreamAnalytics using the SQL-like query language. This query defines how the incoming streaming data is processed, filtered, and transformed before being sent to Power BI. The query can includevarious operationsto extract meaningful information from the data. 3.Specify Output Schema: Users need to specify the output schema that aligns with the structure expected by the Power BI dataset. This includesdefining the data types and structureof the fields that will be sent to Power BI. 4.EstablishAuthentication: To enableAzure StreamAnalytics to push data to Power BI, users need to establish authentication.This typicallyinvolves providing the necessary credentialsor using AzureActive Directory authenticationto ensure secure communication between Azure Stream Analytics and Power BI. 5.Start the StreamAnalytics Job: Once the configuration is complete, users start theAzure Stream Analytics job. This initiates the real-time processing of streaming data based on the defined query logic. As the data is processed, the results are continuouslysent to the specified Power BI workspace and dataset. 6.VisualizeReal-TimeData in PowerBI: In Power BI, users can connect to the configured dataset and create real-time dashboardsand reports. The streaming data from Azure StreamAnalytics is visualized in Power BI, providing users with up-to-the-moment insights into their data.
