  • The past year has witnessed a remarkable change in the IT marketplace with many new entrants, a significant uptick in the number of mergers and acquisitions, growing investment by the venture capital community in enterprise focused companies, and an increasingly competitive and dynamic ecosystem. The technology drivers of social, mobile, cloud, Big Data, and analytics have led to the identification of four mega trends in the 2013 GTO.Growing Scale / Lower Barrier of Entry – Massive expansion in the number of users, sensors and smart devices, channels, relationships, transactions, computations, and the amount of structured and unstructured data is occurring. In 2013, the total of all digital data created is forecast to reach four zettabytes, or 4 x 1021, nearly four times 2010 volumes. A growing number of easy-to-consume application programming interfaces (APIs) for integration with applications, platforms, and infrastructure is lowering the barrier to entry. Increasing Complexity / Yet More Consumable – The volume, variety, velocity, and veracity of data is contributing to the increasing complexity of data management, workloads, and advanced analytics needed to discover insights. For example, novel algorithms to analyze large graphs are resource intensive and new kinds of data management for these graph structures will be needed in the future. Users are becoming more sophisticated and demanding interactive tools for business and scientific visual analytics. The mobile phone has evolved from a simple voice device to a multimedia communications tool capable of uploading and downloading data, text, audio, and video while also functioning as a global positioning system, wallet, FM radio, television, alarm clock, thermometer, address book, newspaper, camera, and more.Fast Pace – Disruptive new models for development and consumption are emerging and increasingly penetrating the enterprise ecosystem resulting in rapid innovation and decreased time to value. Componentized hardware and software is available off the cloud. New web front-end pay-per-use service models are experiencing rapid growth. Social media is influencing how developer and open source communities are engaging in this global ecosystem. Massive open online courses are experiencing exponential growth making education and training more accessible. Contextual Overload – The proliferation of sensors and devices and the explosive growth in structured and unstructured data are causing information and contextual overload. With the increasing affordability and sophistication of smart devices, new opportunities exist to provide contextually aware and personalized services based on user views, desires, preferences, and location delivered just-in-time.
  • Initially funded by an IBM STG University Alliance Faculty Grant which was received in the fourth quarter of 2011.This joint study initiative compliments IBM’s internal research and development in the area of software-defined networking.The initial objectives for this project were to: - establish an SDN development lab with IBM G8264 OpenFlow capable switches - to contribute to the open source community by making contributions to the openflowdistro and open source community - to establish first use cases for OpenFlow - to share our knowledge by writing research papers and presenting at conferences - help students gain knowledge around SDN and OpenFlow - provide the students exposure to professional activities such as conferences and presenting at the IBM Academic of Technology - and to form partnerships with other organizations, companies and clients.Marist has been truly honored and blessed to work with IBM on our Joint Study initiatives. IBM first approached Marist in 1988 to help build a collaborative environment that would provide leadership, guidance, and support to the IBM Academic Initiative through course development, faculty training, and faculty research which allows faculty and students alike access to IBM hardware and software worldwide. This helps Marist and IBM move forward with advances in technology.One of the more recent joint study projects that we’ve been working on is our Software-Defined Networking Lab which was originally funded through a faculty award that I received from IBM which to-date is close to $200,000 dollars.
  • And won’t it be nice when we demonstrate all of this running on anopenflow network.
