Every app on the Azure marketplace is "certified". Every single one.
Here is the list of requirements, which is totally basic for any software company, large and small:
"Business requirements
Your company (or its subsidiary) must be located in a sell-from country supported by Azure Marketplace.
You must sell your application or service in a country where Azure Marketplace is available.
Your application or service must support the English language.
Your licencing model must be compatible with the billing models supported by Azure Marketplace.
Customers with Azure subscriptions must be able to purchase your application or service from Azure Marketplace through their Enterprise Agreement or with a pay-as-you-go subscription.
For your application to be listed on azure.microsoft.com and on the Azure portal, you must provide marketing materials that meet Microsoft criteria.
You must provide customers with a Service Level Agreement, a privacy policy, and phone and online support.
You must make technical support available to customers in a commercially reasonable manner, whether it’s free, paid, or through community support.
Also, you must agree to and comply with the terms and conditions listed in the Azure Marketplace Publisher Agreement and Microsoft Azure Marketplace Participation Policies.
Technical requirements
Virtual machines:
You must test and prepare your application to run well in Azure virtual machines.
Your application must be packaged in a VHD, as described in the Azure documentation for Windows Server and Linux.
Your application’s licensing system must work with the Azure Marketplace hourly billing model or BYOL model, as applicable.
Your application or service must pass validation tests confirming that it runs well in the Azure environment and delivers a high-quality customer experience.
Developer services:
You must confirm that your application service can be provisioned programmatically.
You must be able to manage and track customer usage and provide us with this information in an automated way.
Your billing model must work with and be compatible with the Azure Marketplace billing models.
Your application or service must pass validation tests confirming it is compatible with Azure and delivers a high-quality customer experience.
The whole notion of Microsoft ripping apart the code and "validating" product over and above the requirements shown, and validating a business model before allowing it into the app store is absurd.
IMHO
