4th SG13 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 : [email protected] 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 techn ology - Cloud computing - Overview and vocabulary”

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 3. Expected OPEX reductions – Automation of processes – Improvements for SW validation and upgrade processes – Pooling of HW, energy consumption, HW maintenance 4. Expected CAPEX reductions – Expectations in HW cost reductions – Site strategy aspects, leveraging existing sites versus centralization
