see also [https://github.com/Azure/Azure-Spring-Apps/issues/5](https://github.com/Azure/Azure-Spring-Apps/issues/5)

**Describe the solution you'd like**

In the Java space and specifically in the Enterprise Corp. environment, customers use mainly those 2 Artifact Management solutions:
[JFrog Artifactory](https://jfrog.com/artifactory)
[SonaType Nexus](https://www.sonatype.com/products/nexus-repository)

Priority to JFrog who is already available on the [Azure marketplace](https://azuremarketplace.microsoft.com/en-us/marketplace/apps/aad.jfrogartifactory?tab=Overview)

Please add in the roadmap the ability to deploy Artifcats from Azure BLOB storage or an Artifact Management solution with this priority order :

1. [JFrog Artifactory](https://jfrog.com/artifactory)
2. [SonaType Nexus](https://www.sonatype.com/products/nexus-repository)
3. Azure BLOB storage
4. [GitHub Packages](https://github.com/features/packages)

see also [https://github.com/Azure/spring-apps-deploy/issues/17](https://github.com/Azure/spring-apps-deploy/issues/17)

The experience should be consistent for the developpers when deploying an App whatever the way used :

- Azure Portal
- GitHub Action
- [JFrog Artifactory](https://jfrog.com/artifactory)
- [SonaType Nexus](https://www.sonatype.com/products/nexus-repository)
- Azure CLI
- IaC / ARM / Bicep
- IDE / VSCode extension
