What Does Cloud Application Portability Mean?
Cloud application portability is a concept in cloud computing that refers to the ability to move applications between cloud vendors with a minimum level of integration issues.
Cloud application portability deals with the cross-platform issues in a cloud computing solution platform, particularly software-as-a-service (SaaS) and platform-as-a-service (PaaS)-centered applications.
Techopedia Explains Cloud Application Portability
Cloud application portability is the degree of extent to which certain cloud solution providers design applications that can be ported on other providers and the implementation of standardized, non-proprietary back-end operating platform for enabling cross-vendor applications.
Cloud application portability mitigates the risk of vendor lock-in and ensures that the SaaS application is built over open standards and is portable on most cloud operating platforms. Whether in a traditional model, or a cloud model, vendors of software obviously want to lock-in clients. Given that a big part of the cloud computing model is about freeing an organization from proprietary infrastructure, it only makes sense that open standards are desirable. In practice however, portability is always more complex.
