1 An Evolving Cloud Service Delivery Model from Network Operator s Perspectives by Alan Chan, Hutchison Global Communications 1

2 An Evolving Cloud Service Delivery Model from Network Operator s Perspectives Agenda Network infrastructure Data center facilities & computing resources Security Billing & operation support systems Opportunities 2

3 Definition Definition of Cloud Computing By National Institute of Standards and Technology (NIST) v15 A model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction Three services models Cloud Infrastructure as a Service (IaaS); e.g., Virtual server instance with CPU(s) Storage blocks Cloud Platform as a Service (PaaS); e.g., A set of software and product development tools Cloud Software as a Service (SaaS); e.g., Software, application and database 3

4 Network Infrastructure Key enabler of Cloud Broadband accessing technology Global data transmission speed Access Reliable Real-time or near-real-time performance, comparing to localized storage HSPA and soon LTE allow users to use cloud services anytime, anywhere without geographical limitation High penetration of mobile computing devices further drive the use of cloud Backbone Complemented by metro-ethernet, global-ethernet and revived subsea cable industry 4

5 Network Infrastructure (cont d) Backbone (cont d) Single wavelength increased from 10Gbps to 40Gbps and soon 100Gbps Metro network speed moving from GE to 10GE More cable built in the recent years Latency, total capacity and network reliability thru highly direct-routing and better cable diversity Adoption of intelligent re-routing technology (ASON) further improves the cable restoration performance Local and int l IP infrastructure has to be more dynamic and scalable to support various cloud services with pay-as-you-use basis Network operator to provide SLA Short latency real-time performance High service availability minimal services interruption 5

6 Data Center facilities and computing resources Well-built, secured and cost-efficient data center Abundant power supply and cooling facilities Compartment design Advancement in server capability (high density servers) Scattered locations of smaller data centers Abundant network connectivity and diversity Footprint Within a few hops away from major Ixs or gateway Spread over a wide footprint and perhaps even globally 6

7 Security Large enterprises are more cautious Consumer market and SMB usually prefer save up capex for core biz Growing concern in data and network security in cloud Most organizations are not strong in security skill and mechanism Cost effective security package itegrated in the cloud Capitalize on credibility and experience in managed service to offer cloud Built on trust? Industrial Compliance Visibility of security measures for auditing purpose Personnel in compliance development 7

8 Security (cont d) More resources are needed in network protection Design approach event can be easily identified, isolated & mitigated Security expertise in O&M Involve VPN solutions to minimize unnecessary public exposure Internal and public access layered in different zones (hybrid approach) 8

9 Billing & Operations Support Systems Capable to realize the virtualized resource utilization and bill On-demand provisioning Standardized product Flexible and easy to use Allow service provisioning anywhere and anytime Dynamic and automated billing Pay-as-you-use Pre-paid Coupon or pre-paid account (e.g., Gift card) Buffet plus tier cost Up to a fixed amount of resources per month (e.g., CDN) Full payment upon subscription (e.g., Application store) Capable in measuring application performance SLA SLA no longer restricted to network infrastructure 9

10 Opportunities More than just a dumb pipe biz Poses an opportunity for network operators to move up in the value chain in the cloud and thus the future telecom eco-system Forward linkage Determine the focus in particular domestic sectors Industry sectors that can create demand for cloud-based services Move on-premise applications into the cloud Backward linkage - Related to the strength to deliver services On its own ; OR Partners with ingredients that offer development of the cloud industry SaaS & PaaS - Software firm, apps developer, content provider, user device manufacturer, BOSS IaaS Alliance with interstate or global IaaS providers 10
