4thSG13 Regional Workshop for Africa on Future Networks for a better Africa: IMT-2020, Trust, Cloud Computing and Big Data (Accra, Ghana, 14-15 March 2016) Cloud Manager Approach ABDALLAH AJLANI Ph.D Principal Consultant, ERICSSON Email : abdallah.ajlani@ericsson.com Byline
Cloud Computing Definition Cloud computing is Paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand. Source: ISO/IEC 17788 | Recommendation ITU-T Y.3500 Information technology - Cloud computing - Overview and vocabulary
SDN, Cloud and NFV Management & Orchestration Cross Domain Control, Orchestration & Management SDN CLOUD NFV Virtualize Scale Control
Change Drivers voices from the industry Innovation Providing cloud services to enterprise Kris Rinne, Senior VP of Technology, AT&T Speed Bring products to market much quicker Mike Wright, Executive Director, Telstra Efficiency Radically simplified network Bruno Jacobfeuerborn, CTO DT
Operator drivers for cloud Transformation 1. 2. Separation of SW/HW to avoid current vendor-lock in and increase flexibility To address new services with reduced TTM Easier to launch new services Expected OPEX reductions Automation of processes Improvements for SW validation and upgrade processes Pooling of HW, energy consumption, HW maintenance Expected CAPEX reductions Expectations in HW cost reductions Site strategy aspects, leveraging existing sites versus centralization 3. 4.
