A developer is planning a migration to Azure Cosmos DB. They have a workload that performs 100 point reads per second. Each point read is expected to consume 2 RUs. The developer wants to provision enough throughput to handle the workload with a 10% buffer. What is the minimum provisioned throughput (in RU/s) required?

A developer is designing a new application that will perform a mix of point reads and queries. The developer has estimated that point reads will consume 2 RUs each and queries will consume 10 RUs each. The application will perform 50 point reads and 10 queries per second. The developer wants to provision throughput with a 20% buffer. What is the minimum provisioned throughput (in RU/s) required?

A team is designing an Azure Cosmos DB for NoSQL container for a social media application. They need to estimate the RU cost for a point read operation that retrieves a single item by its `id` and partition key. The item size is 5 KB. The container has a default indexing policy. What is the best way to estimate the RU cost for this point read?
