This is a world of more possibilities, more innovation, more openness, and the sky is the limit thinking in a cloud-enabled world.Microsoft's Azure Data engineering team is leading the transformation of analytics in the world of data with products like databases, data integration, big data analytics, messaging & real-time analytics, and business intelligence. The products our portfolio include Microsoft Fabric, Azure SQL DB, Azure Cosmos DB, Azure PostgreSQL, Azure Data Factory, Azure Synapse Analytics, Azure Service Bus, Azure Event Grid, and Power BI. Our mission is to build the data platform for the age of AI, powering a new class of data-first applications and driving a data culture. Within Azure Data, the databases team builds and maintains Microsoft's operational Database systems. We store and manage data in a structured way to enable multitude of applications across various industries. We are on a journey to enable developer friendly, mission-critical, AI enabled operational Databases across relational, non-relational and OSS offerings. We are the Azure SQL DatabaseStorage/IO resource governance team, part of the Microsoft Azure's C+ AI organization. Our team is responsible to ensure high efficiency of operations while interacting with storage which persists with the data. We govern the IO resources available to our customers ensuring we optimize the performance of their workload while also ensuring equitable and fair distribution of these resources across different customers, hardware, offerings, etc. In addition to maintaining an efficient Quality of Service (QoS) with respectto latency and bandwidth, the team is also responsible for ensuring the customer gets the right kind of storage medium based on their need and historical usage pattern. Based on the customer needs, the team is responsible for putting them on the right tier of storage, moving them across to a different storage medium if desired with minimal downtime, analyze and rectify customer workload for efficient storage utilization. Azure SQL has more than 100 million databases under its belt, and for its efficient operation has an even higher number of storage resources allocated. The team is responsible for efficient functioning of storage on all parameters and for all services.
