IT Service Management Lifecycle

� IT Infrastructure Library (ITIL) is the most widely accepted approach to IT Service Sanagement. It provides a best-practice framework for identifying, planning, delivering and supporting IT services to the business.


ITIL V3 Components

Definition of Service Operation

� IT InfrastructureAll of the hardware, software, networks, facilities, etc., that are required to Develop, Test, deliver, Monitor, Control or support IT Services. The term IT Infrastructure includes all of the Information Technology but not the associated people, Processes and documentation.


� Service OperationService Operation is the phase in the IT Service Management Lifecycle that is responsible for ‘business-as-usual’ activities.

Service Operation is where the value is actually delivered.

Source: ITIL V36

Main Goals of Service Operation

� achieving effectiveness and efficiency in the delivery and support of services

� ensure value for the customer and the service provider

� maintain stability in Service Operations, therefore allowing for changes in design, scale, scope and service levels

� providing methods and tools for use in the two major control


� providing methods and tools for use in the two major control perspectives:� reactive� proactive

� providing knowledge to make better decisions in areas such as managing the availability of services, controlling demand, optimizing capacity utilization, scheduling of operations and fixing problems

Q & A6


Definition

� A service is a collection of applications and capabilities that provides value to a customer� Typically involves a number of individual servers, each supporting one or more

applications� Services are complex systems, often the needs of the system is greater than

the sum of the need of individual servers


Challenges and Cost Factors in Today´s Enterprises

� Slow service delivery� Bringing a new service to life involves multiple teams� Poor coordination can mean service delivery times of 90+ days

� Lack of transparency� Poor visibility into the operations of business services makes it hard to

guarantee service levels and correctly interpret anomalies

� Too little automation


� Expensive and error prone manual workflows can lead to business service disruptions

The Service Oriented Data Center


Standardize Infrastructure Delivery

� Return cost visibility to the system by delivering standardized infrastructure components

� Infrastructure specification + Service-level agreement� Account for the cost of providing the requested level of service� Clearly differentiate between service levels and server capabilities by exposing

cost� Provide an array of different options via catalog

� Standard components and standard SLA´s made available to the business


� Standard components and standard SLA´s made available to the business with visible cost structure� Simplify planning on both sides of the transaction

Q & A6


Virtualization Technology Overview

� Old Model / Traditional x86 Architecture� Single OS image per machine� Software and hardware tightly coupled� Multiple applications often conflict


� Multiple applications often conflict� Underutilized resources

State of Infrastructure Today – Physical

Server Sprawl55 m physical servers by 2012 - 700% increase in 15 years$140 bn in excess server capacity - a 3-year supply

Power & Cooling

50c for every $1 spent on servers$29 bn in power and cooling industry wide


Operating Cost

$8 in maintenance for every $1 spent on new infrastructure20-30 : 1 server-to-admin ratio

Space Crunch

$1,000 /sqft$2,400 / server$40,000 / rack

What is Virtualization?

Hardware

Application

Operating System

Without Virtualization


� Provides hardware virtualization that presents a complete x86 platform to the virtual machine

� Allows multiple applications to run in isolation within virtual machines on the same physical machine

� Virtualization provides direct access to the hardware resources to give you much greater performance than software emulation

Virtualization Increases Hardware Utilization

Before Virtualization After Virtualization


Virtualization enables consolidation of workloads from underutilized servers onto a single server

to safely achieve higher utilization
