Today, AWS Marketplace released new feature enhancements to the Seller Self-Service Listings feature, a web-based interface that lets AWS Marketplace software vendors manage their product listings through the AWS Marketplace Management Portal (AMMP). Starting today, software vendors that have product listings in AWS Marketplace can use Self-Service Listings to make changes to their Amazon Machine Image (AMI)-based product listings, including updating product metadata, uploading new versions, making changes to instance types and pricing, and more. In addition, Self-Service Listings allows vendors to create new AMI-based or SaaS Subscriptions product listings.
