Are bandwidth limits for APIM and Storage account impacted by number of connected clients?

Question

I have been reading network limits (e.g. RPS) for Azure APIM and Azure Storage Account and I wanted to ask if -by default- limits are lower if most of the data are sent from a single client.

That is, is there any default rate limiting if it is a single client executing most of the requests or it is actually a favorable condition to have the least number of clients executing operations as? Or simply, it has nothing to do with number of clients but strictly to number of requests.

Thanks!

The bandwidth limits for Azure API Management (APIM) and Azure Storage Accounts are primarily determined by the number of requests and the types of operations performed, rather than the number of connected clients.

In the case of Azure API Management, rate limits are typically configured to protect against spikes in traffic and can be applied based on specific keys (such as IP address or subscription ID). However, by default, these limits are not tied to the number of clients. Instead, they are enforced based on the total volume of requests.

For Azure Storage, performance targets and limits are also governed by factors like request rate, object size, and access patterns. These limits apply regardless of whether the requests are made by a single client or multiple clients.

Therefore, having a single client making most of the requests does not inherently reduce the service limits. The determining factors are the total number of operations and their nature, not the number of clients involved.
