1 itsmf Annual Conference 2012 Applying ITIL to Cloud Computing Mr. HP Suen Director itsmf International Executive Board

2 Agenda Definition of Cloud Computing On-demand self service Pool of resources Pre-production activities ITIL lifecycle

3 On a sunny day in February 2009 CIO to Heads of Department, When can we have Cloud?

4

5 Definition of Cloud Computing A model for enabling convenient, ondemand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications, and service) that can be rapidly provisioned and released with minimal management effort or service provider interaction. (National Institute of Standards and Technology)

6 Definition of Cloud Computing This cloud model is composed of 3 service models 4 deployment models 5 essential characteristics

7 Service Model Software as a Service Platform as a Service Infrastructure as a Service

8 DeploymnetModel Private cloud Public cloud Community cloud Hybrid cloud

9 Essential Characteristics On-demand self service Broad network access Resource pooling Measured service Rapid elasticity

10 Scope of Cloud Computing in this presentation A model for enabling convenient, on-demand network access to a shared pool of configurable computing resources(e.g. networks, servers, storage, applications, and service) that can be rapidly provisioned and released with minimal management effort or service provider interaction. In-house application of Cloud Private Cloud

11 On demand self service Request handling Scope of service CPU, Operating System, Storage, backup Available options/quantity GB storage Daily, weekly backup Availability Monday -Saturday Monday Friday Sunday and Public Holiday subject to approval

12 On demand self service Supporting process and function Account management Authority Security Metering of usage Billing and payment

13 Resource Pooling shared pool of configurable computing resources (e.g. networks, servers, storage, applications, and service) Storage

14 Resource Pooling Storage

15 Resource Pooling Specification / requirements Relationship Ownership location Storage

16 Resource Pooling How does it affect Provisioning Service desk Incident handling Planning and forecast Capacity management

17 Resource Pooling Problem management Change management license and billing Data backup and restore Network connectivity Need an up-dated and easily available 4 configuration information to support

18 Resource Pooling Monitor and event management End-to-end, from server to end-point Bandwidth Firewall, load balancer Utilization of CPU, memory,storage Threshold Auto-recovery Off-line analysis and forecast

19 Pre-production Activities

20 Testing before production Integration of supporting technologies End-to-end connectivity, dependencies Monitor and event management Verify procedures and event threshold values Capacity and performance Load test, stress test, etc; Storage, memory, bandwidth Documentation Accuracy and completeness

21 Change Management Integration of supporting technologies Relationship between local and remote components Release and deployment Version control Execution Procedures and the best date / time Training

22 Cloud Computing and the ITIL Lifecycle

23 ITIL Life Cycle Process Service Strategy Service Design Portfolio Availability Demand Capacity Financial IT Service Continuity Information Security Supplier Service Catalog Service Level Service Transition Change Service asset and configuration Release and deployment Service validation and testing Evaluation Knowledge Service Operation Service Desk Incident Problem Request fulfillment Access Event Technical IT Operations Application

24 ITIL Life Cycle Process Service Strategy Portfolio Service Design Availability Demand Capacity Financial IT Service Continuity Information Security Supplier Service Catalog Service Level Service Transition Change Service asset & configuration Release and deployment Service validation & testing Evaluation Service Operation Service Desk Incident Problem Request fulfillment Access Event Technical IT Operations Application

25 3 take-away Blending of the New and Old Pay attention to Service Transition & Service Operation Apply the proven methodology to Cloud Computing Projects.
