The total cost for using {{site.data.keyword.cos_short}} for {{site.data.keyword.satelliteshort}} is a combination of:

2. Base {{site.data.keyword.satelliteshort}} charge
3. {{site.data.keyword.cos_short}} fixed capacity pricing

Choosing capacity

{: #billing-satellite-sizing}

The storage instance capacity is set during the provisioning process. You will need to work with your {{site.data.keyword.satelliteshort}} administrator to ensure that enough raw capacity exists in the underlying {{site.data.keyword.satelliteshort}} infrastructure.

As each application has unique storage needs, it is not possible to provide much in the way of generic guidance for choosing a capacity. Take into account the nature of the application (for example, processing high-resolution satellite imagery or 4K video will require a greater capacity than a simple document repository) and the expected scaling of storage needs, and consult IBM Cloud support as needed.

Adding capacity

{: #billing-satellite-adding}

At this point, it is not possible to extend capacity once an instance is provisioned. Instead, you will need to provision an additional instance and create a new bucket for the overflow.
