For this situation, how can we save the bandwidth cost ("Outbound data transfer")?

Also, can apply Azure CDN save the cost?

    The ability of Azure CDN to cache static objects closer to users reduces the amount of data that must be transferred from your application's main server. This can assist in lowering bandwidth costs. However, CDNs are only useful for caching static content and will not assist with dynamic content or file uploads. If you're using Azure VMs and know you'll need a certain amount of bandwidth for a long time, consider Reserved Instances, which offer discounted rates in exchange for a one- or three-year commitment. Also, to avoid inter-region data transfer costs, try to keep your resources in the same region. Transfers between your VM and storage account, for example, are free if they are in the same region.
