Cloud computing is believed to be another big wave of Internet technology after World Wide Web and mobile computing. The Open Group has identified cloud computing as a major driver to develop global GDP. In Hong Kong, the Office of Government CIO (OGCIO) has established the Expert Group on Cloud Computing Services and Standards (EGCCSS) to drive cloud computing adoption and deployment. Various cloud technical committees, including the two groups mentioned above, have identified the interoperability and portability of cloud services as a key principle for stimulating and driving economic benefits. EGCCSS has formed a Working Group Cloud Computing Interoperability Standards (WGCCIS) specifically to address this challenge.
In this talk, Dr Thomas Lee shares his experience in working in WGCCIS as a co-opt member and introduces the Open Group Guide on Cloud Computing Portability and Interoperability. He explains the fundamental concepts of cloud interoperability and portability and the reference architecture to design interoperable interfaces between on-premise and cloud application components. He also discusses the architectural principles for supporting cloud service providers to develop interoperable cloud services. From the enterprise user perspective, he also summarizes some good practices from the Open Group Guide that help cloud consumers to formulate their cloud strategy to manage vendor lock-in when selecting cloud services.
