The volume and complexity of data generated by modern organisations has led to an increasing need for flexible and reliable tools for data analysis and visualisation. Microsoft Power BI is a popular business intelligence application that allows users to create interactive dashboards, generate reports, and connect to multiple data sources. Businesses may process, store, and analyse data in real-time by utilising cloud computing platforms like Azure and AWS, which offer scalability, speed, and cost-effectiveness. This study looks at the benefits, challenges, and best practices of using Power BI in the cloud. Case studies of real-world deployments are also included.
