Please note, recently we have launched Aspose.Words Cloud Docker Container, a self hosting solution. We are in the process of launching Docker Container of the other Aspose Cloud APIs in the near future as well. So currently now, you can deploy Aspose.Words Cloud API at your own premises for Word document processing solution without depending on the api.aspose.cloud. Please check the documentation for details to run Aspose.Words Docker Container and this forum post for details.
Furthermore, please note the pricing plan is the same as our cloud based service with the exception that storage methods are not charged. To purchase and receive a Cloud Metered License key please contact the Aspose Cloud sales team and feel free to contact us for any further assistance.
