Over the past couple of years, we have collaborated with numerous customers to tackle performance, scaling, and cost issues that arise when transitioning their Azure Cosmos DB for NoSQL API based applications to production. In many cases, these challenges stem from a lack of understanding of key Azure Cosmos DB concepts. To address this, We teamed up to create a scenario-based learning video series.

We are thrilled to present three informative YouTube videos that delve deep into the workings of Azure Cosmos DB. These videos cover a variety of crucial topics essential for successfully transitioning your prototype to production.

Who Should Watch?

This series of videos are intended to provide an understanding of Azure Cosmos DB’s features and best practices. Whether you’re a novice just starting with Azure Cosmos DB or a seasoned developer looking to enhance your skills, these videos are an invaluable resource.

What You’ll Learn

Each of the three episodes covers a distinct aspect of Azure Cosmos DB and highlights common mistakes made by customers.

  • Episode 1
    • Choosing the Ideal Partition Key: Discover how to select an optimal partition key for superior data distribution and enhanced query performance.
    • Monitoring and Troubleshooting: Learn best practices for monitoring and troubleshooting your Azure Cosmos DB application using Metrics and Telemetry.
