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

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
