The latest ARN Roundtable, held at Sydney's Bentley restaurant, saw representatives of businesses in the channel discuss issues surrounding the Cloud, Big Data and datacentres. They spoke about the need for transparent cost models, the purpose of having a consulting world in these industries, as well as the need for companies to alter their offerings to meet each individual customers' needs. The attendees also discussed data sovereignty, the growth of applications, and the quality of Australia's telco infrastructure. This roundtable was sponsored by Cisco, IBM and Ingram Micro.
