On Wednesday, the Cloud Foundry Foundation announced news of a certification program that aims to ensure inter-operability and portability within the multi-vendor environment that leverages the open source Cloud Foundry Platform as a Service (PaaS). IBM Bluemix, Pivotal Cloud Foundry, CenturyLink AppFog and SAP HANA Cloud Platform represent some of the vendors that received the first seal of approval and certification from the newly launched program. The certification program constitutes a huge leap forward toward ensuring the portability of applications across vendors that offer PaaS platforms based on Cloud Foundry. By reducing vendor lock-in amongst users of the Cloud Foundry platform, the certification program signals the emergence of standards and recognized units of measure within the cloud computing space. The program promises to usher in a new era of certification and standards for inter-operability across cloud environments and thereby pave the way for greater collaboration between vendors and enhanced operational agility for cloud computing customers.
