Today, we are excited to announce the public preview of the Cloud Partner Portal for publishing single virtual machine offers. The Cloud Partner Portal enables our publisher partners to create, define, publish and get insights for their single virtual machine offerings on the Azure Marketplace.
With this announcement, new and existing publisher partners who wish to publish virtual machines onto Azure will be able to use the new Cloud Partner Portal to perform any of the above actions. This new portal will soon support all other offer types and will replace the current publishing portal in time.
