Topic 1, Litware, inc Requirements Planned Changes Litware plans to implement a new Azure Cosmos DB Core (SQL) API account named account2 that will contain a database named iotdb. The iotdb database will contain two containers named con-iot1 and con-iot2. Litware plans to make the following changes: Store the telemetry data in account2. Configure account1 to support multiple read-write regions. Implement referential integrity for the con-product container. Use Azure Functions to send notifications about product updates to different recipients. Develop an app named App1 that will run from all locations and query the data in account1. Develop an app named App2 that will run from the retail stores and query the data in account2. App2 must be limited to a single DNS endpoint when accessing account2. Requirements. Business Requirements Litware identifies the following business requirements: Whenever there are multiple solutions for a requirement, select the solution that provides the best performance, as long as there are no additional costs associated. Ensure that Azure Cosmos DB costs for IoT-related processing are predictable. Minimize the number of firewall changes in the retail stores. Requirements. Product Catalog Requirements Litware identifies the following requirements for the product catalog: Implement a custom conflict resolution policy for the product catalog data. Minimize the frequency of errors during updates of the con-product container. Once multi-region writes are configured, maximize the performance of App1 queries against the data in account1. Trigger the execution of two Azure functions following every update to any document in the con-product container.
