Suggested Answer:

Box 1: Provisioned throughput -
Provisioned throughput is best suited for workloads with sustained traffic requiring predictable performance.
Billing model: Billing is done on a per-hour basis for the RU/s provisioned, regardless of how many RUs were consumed.
Scenario: Ensure that Azure Cosmos DB costs for IoT-related processing are predictable.
Note: Azure Cosmos DB is available in two different capacity modes: provisioned throughput and serverless. You can perform the exact same database operations in both modes, but the way you get billed for these operations is radically different.
Box 2: Autoscale throughput on iotdb and throughput sharing across the containers
You can enable autoscale on a single container, or provision autoscale throughput on a database and share it among all the containers in the database.
Cost-effective: Autoscale helps optimize your RU/s usage and cost usage by scaling down when not in use. You only pay for the resources that your workloads need on a per-hour basis.
Incorrect: cannot autoscale on two containers.
Note: Autoscale provisioned throughput in Azure Cosmos DB allows you to scale the throughput (RU/s) of your database or container automatically and instantly.

Manual Scale seems most appropriate: Workloads with steady or predictable traffic ( 5k telemetry per second is predictable) https://docs.microsoft.com/en-us/azure/cosmos-db/how-to-choose-offer#:~:text=You%20have%20high%2C%20consistent%20utilization%20of%20provisioned%20RU/s.

Capacity Mode : Provisioned Scale config : Manual Reason - telemetry data is coming in at a constant rate with no spikes or unpredictable changes - we have an exact number of devices that are sending telemetry data of exact size with non-changeable frequency.
