Here are some important criteria for ISVs to consider in evaluating PaaS provider:

It becomes more relevant when a vendor is able to support cross sets of platform and languages (e.g VM Cloud foundry support open source code) in its PaaS offering.
- Integration: The integration with other services available from the vendor, provides the enterprises an option of building complex applications with ready to consume standard cross cutting services like email, search, content management, BI soutions and more.
- Development and Testing Environments: Development of application in PaaS delivery model asks for offline development tools. Also, as part of the release cycles the deployment process Smart PaaS providers will have the capability of providing a staging environment which is close to the production.
