As an early proponent of internet technologies, he held executive-level positions at Sun Microsystems, Salesforce.com, and Cisco Systems contributing to the advancement of the Java programming language and platform, the AppExchange on-demand application marketplace, and the OpenStack cloud computing platform. 
Early life and education.
Tucker grew up near Asbury Park, New Jersey, the son of big band Leader Tommy Tucker. He attended The Peddie School high school in Hightstown, New Jersey, and graduated from Cornell University with a B.A. in Biology. 
Career.
Having interests in neurobiology and computer science, in 1976 Tucker started as a laboratory technician at the Laboratory of Neurobiology at Cornell University Medical College. He later become an assistant research scientist bringing computing to medical imaging and contributing to several research papers on neurogenic control of hypertension. He completed a Masters and Ph.D. in computer science from Polytechnic Institute of New York in 1984. His dissertation spanned both computer vision and parallel machine architectures for biomedical image analysis.
Upon completing his Ph.D., Tucker joined a new startup, Thinking Machines, in Cambridge, MA. Thinking Machines was founded by Daniel Hillis to develop technology for artificial intelligence using parallel computing. As research director for computer vision, Tucker contributed to the software and architecture of the Connection Machine, an early commercial massively parallel machine containing over 65,000 processors that was used by national laboratories working on supercomputing grand challenges.
In 1994 Thinking Machines was acquired by Sun Microsystems. Tucker joined Sun to lead an engineering team brought in from Thinking Machines in Chelmsford, MA. A year later, he moved to California as part of an initial team of developers and executives behind Java, a new programming language and platform designed for the emerging web. Tucker became Director of ISV Relations, evangelizing the use of Java technology by large corporations and startups alike. He was a frequent speaker on how the growing internet would become a force in the industry and was featured alongside other internet pioneers in "Digerati: encounters with the cyber elite". In 2000, at Sun Microsystems, Tucker became VP of Internet Services responsible for www.sun.com and java.sun.com. 
In 2004, Tucker left Sun to join Salesforce.com where he created the AppExchange, one of the first online marketplaces for software-as-a-service applications. He left Salesforce.com to join Radar Networks, to advance a new semantic web platform, Twine.com, based on RDF.
With the emergence of Amazon’s Web Services (AWS) cloud platform, Tucker returned to Sun Microsystems in 2008 as Vice President and CTO to develop Sun’s platform for cloud computing. Just prior to launching Sun Cloud, the company was acquired by Oracle in 2010 shutting down the effort. 
Tucker left to join Cisco Systems, Inc., as the company’s first VP and Chief Technology Officer for cloud computing. As Cloud CTO, Tucker moved Cisco into becoming a major contributor to the open source developer community being built around OpenStack. He served as vice-chairman of the OpenStack Foundation, and board member of the Cloud Native Computing Foundation, and Cloud Foundry Foundation.
