Virtualization Technology Will Re-shape it Infrastructure

In a fiercely competitive auto industry, Mazda North USA depends on IT to inject the same “Zoom-Zoom” that characterizes their automobiles into its business operations. As Mazda’s IT initiatives such as increasing field managers’ effectiveness grew, so did its server count – from 150 to nearly 300. “With a one-application-per-server approach and pressure to heighten system availability, all we could see was server sprawl. Complexity rose to the point where our IT staff was spending most of its time just maintaining those servers,” states Jim DiMarzo, CIO of North USA Operations. In addition, increasing energy costs were causing power and cooling expenses to overtake equipment costs. To help solve their problems, Mazda turned to virtualization technology.

As virtualization technology becomes increasingly inexpensive and more consistently provides measurable business value, more and more organizations are following in Mazda’s footsteps.

Virtual Machines (VMs) – the heart of Virtualization Technology

At the heart of virtualization solutions are virtual machines (VMs), which grant multiple instances of operating systems to run on the same physical server at the same time. The primary benefit of VMs is increasing the number of software applications you can run reliably on a single physical server. Historically, due to concerns over potential conflicts, applications such as email or timekeeping software have apiece been installed on their own physical server.

Server Consolidation – the Key to Cost Reduction

Virtualization techniques help contain server sprawl. For example, virtualization technology granted Mazda to consolidate 75 of their servers onto five powerful, energy efficient servers. It also enabled them to decrease the number of people required to manage nearly 300 virtual and physical machines from eight to five. In addition, VMs have granted Mazda to reduce the amount of power as well as data center and office space they require.

Additional Benefits – Cost-effective Business Continuity, Rapid Software Deployment, Improved Legacy Application Management

There are several additional benefits virtualization technology provides. For example, organizations can help ensure high availability for critical applications using virtualization solutions. These solutions enable them to act as if their application is supported by multiple machines without the cost, complexity and time required to support physical organisation clusters.

Virtualization technology enables organizations to implement a disaster recovery platform that grants them to make all their company information acquirable within hours in the event of hardware loss without investing in pricey one-to-one mapping of production hardware to disaster recovery hardware.

Virtualization solutions also enable organizations to move or implement new applications within hours rather than days because virtualization technology helps shield software from hardware variability.

In addition, organizations can migrate legacy operating systems and software applications to VMs running on upgraded hardware for enhanced reliability and resource management.

Looking Forward – Virtualization Technology will Re-shape IT Infrastructure

Virtualization is becoming an increasingly cost-effective way, even for midsize organizations, to obtain more value from IT. We expect virtualization to be one of the most significant factors shaping IT infrastructure and operations over the next several of years. As a result, we have invested in becoming certified as a VMWare Partner. We expect incorporating virtualization techniques in 2008 as part of a program to reduce hardware costs and wage much more inexpensive disaster preparedness.

INFORMATION TECHNOLOGY INFRASTRUCTURE LIBRARY

INFORMATION TECHNOLOGY INFRASTRUCTURE LIBRARY –

GUIDE TOWARDS PROGRESSIVE INFORMATION TECHNOLOGY BUSINESS

 

SUMMARY

 

The Information Technology Infrastructure Library is a set of concepts and policies for managing information technology (IT) infrastructure, development and operations. ITIL is the most widely accepted approach to IT Service Management in the world. It promotes a calibre approach to achieving business effectiveness, economy and efficiency in the use of information systems. The ethos behind the development of ITIL is the recognition that organizations are becoming increasingly dependent on IT in order to satisfy their corporate aims and meet their business needs. ITIL is a cohesive ideal practice framework, drawn from the public and private sectors internationally. It describes the organisation of IT resources to deliver business value, and documents processes, functions and roles in ITSM. ITIL is to be adopted and built upon by an organisation as per its purposes and needs. ITIL is supported by a comprehensive qualifications scheme, accredited training organisations, and implementation and assessment tools. In today’s competitive market, being ITIL complaint is a definitive edge over the competitors.

 

The latest generation of the ITIL is titled “ITIL v3“. This version represents an important evolutionary step in ITIL’s life. ITIL has transformed the guidance from providing a great service to being the most innovative and ideal in class. In general, ITIL v3 makes the link between ITIL’s ideal practice and business benefits both clearer and stronger. The main development is that ITIL v3 guidance takes a lifecycle approach, as opposed to organising according to IT delivery sectors.

 

This article focuses on giving readers a brief understanding of the ITIL.

 

INTRODUCTION

 

Information Technology Infrastructure Library (ITIL) is a series of books that are used to aid the implementation of a framework for IT Service Management (ITSM). Being a framework, it is absolutely customisable for application within any type of business or organisation that has a reliance on IT infrastructure. The ITIL originated as a collection of books apiece covering a specific practice within ITSM. ITIL books are developed by Office of Government Commerce, U. K. (OGC). It is the world’s de-facto standard ideal practice framework for ITSM. OGC also has qualification certification program for ITIL followers.

 

ITIL is cornerstone of good calibre ITSM and a necessity for calibre assurance. It provides a systematic, process-based approach, supported by procedures for key IT service management processes. ITIL is Technology independent. ITIL gives a detailed description of a number of important IT practices with comprehensive checklists, tasks and procedures that can be plain to any IT organization.

 

The ITIL series consists of several books providing guidance on the planning, delivery and management of calibre IT services to support business needs comprising issues pertaining to Service Support, Service Delivery, IT Infrastructure Management, Application Management, Business Perspective, Security Management. ITIL has clear definition of various terms used in ITSM in a concise yet comprehensive manner.

 

 

 

 

UTIILTY OF ITIL

 

ITIL provides a comprehensive set of guidance to link the technical implementation, operations guidelines and stipulations with the strategic management, operations management and financial management of a modern business. Among the benefits associated with adopting the ITIL which have been identified by the users are improved customer satisfaction with IT services, superior communications and information flows between IT staff and customers, superior management control over ITSM and reduced costs in developing and implementing procedures and practices within an enterprise.  ITIL improves the performance of processes which are being followed in an organization leading to high calibre output.

 

It goes into great detail regarding the process, implementation and the content of the key deliverable of the Service Level Agreement (SLA) and Service Level Stipulations (SLRs).

 

ITIL contains tried and tested processes. It has a quick-start approach to help in making the ideal use of time and resources acquirable and see swift results. It led to improved productivity of the organisation itself and also of delivery of third celebration services through the specification of ITIL. The well defined ITIL processes also minimizes duplication of efforts, dropped hand-offs and unapproved work. Additionally, individuals acquire a superior understanding of roles and responsibilities and how they apiece contribute to the success of IT and the business. It separates administrative tasks and technical tasks to help in assigning the most appropriate resources.

 

In short, ITIL improves efficiency, effectiveness and economy of the ITSM.

 

ITIL – ITSM

 

ITIL describes the management of IT Services in the context of the lifecycle of those services. The focus of ITIL this day is integration of IT into the business, assuring the delivery of business value and the treatment of services as business assets. ITIL describes the life of a service from conception to retirement, within a Service Portfolio detailing aspects of planning and development as well as objects, specification, description and stipulations of the services in use or being offered for use through means of the processes. Each process has a home in the lifecycle stage book where it is most active. The lifecycle approach gives an improved, holistic structure within which to describe all the functions, processes, roles and responsibilities that constitute ITSM Ideal Practice.

The two basic stipulations of ITSM are:

 

(a)               Service Delivery: ITIL’s Service Delivery component includes tactical processes necessary for planning and delivering calibre IT services, which is defined in SLA. Service Delivery ideal practices address Availability Management, Capacity Management, Service Level Management, Service Continuity Management (contingency planning) and Financial Management for IT Services.

 

(b)               Service Support: ITIL’s Service Support component focuses on the operational processes that enable companies to wage IT Support and maintenance activities on a day-to-day, around-the-clock basis. Service Support disciplines include Change Management, Configuration Management, Problem Management, Incident Management and Release Management (including software and hardware control and distribution). This includes service desk artefact as single point of contact and disaster recovery mechanism. The neutral is to minimize disruption to the business by proactive finding and analysis of the cause of service incidents and by managing problems to closure.

CMDB

One of the primary elements of ITIL is Configuration Management Database (CMDB). CMDB is a database, which contains all relevant details of apiece Configuration Item (CI) and details of the important relationships between CI’s. CI is a part of an IT infrastructure or an item associated therewith which is under control of configuration management for ITIL implementation.

 

The ITIL goal of Configuration Management is to keep records of all IT data, IT processes and IT policies and to wage information to the other processes. Critical steps are the population of the CMDB and building the relationships between all the populated elements. The captured data can be used for decision support, for change impact analysis, release management verification identifying rogue changes and any number of other information processing and analysis purposes. CMDB helps in keeping track of all ITIL processes.

 

Deming Circle

 

For calibre improvement W. Edwards Deming proposed the Deming Cycle (or Circle). The four key stages are Plan, Do, Check and Act after which a phase of consolidation prevents the ‘Circle’ from ‘rolling downs the hill’ as illustrated:-

 

 

 

 

ITIL is built around a process-model based view of controlling and managing operations often credited to Mr. Deming. ITIL helps in achieving the Deming Circle. ITIL is a process led approach. Quality management for IT Services is a systematic way of ensuring that all the activities necessary to design, develop and implement IT services which satisfy the stipulations of the organization and of Users take place as planned.

 

Implementing the change

 

Besides having human resource having knowledge and experience of ITIL, business needs a Change Advisory Board (CAB) so that ITIL is implemented with commitment and efficiency. CAB approves and controls the required changes within the acceptable level of risk.

SLA

 

One of the important components of service delivery is the service level agreement. A SLA is fundamental to service provision, from the appearance of both the supplier and the recipient. It documents and defines the parameters of the relationship itself.   The calibre of the SLA is therefore a critical matter.

 

SLA is a legal document which ensures that the proper elements, understanding, commitments and deliverables are in place to wage consistent service support and delivery as per SLR. SLR indicates the expected customer specifications, stipulations and characteristics of the service delivery. The intent of SLA is to specify the detailed levels of services to refrain future differences on deliverables. Typical SLA sections include: Introduction, Scope of Work, Performance, Tracking and Reporting, Problem Management, Compensation, Customer Duties and Responsibilities, Warranties and Remedies, Security, Intellectual Property Rights and Confidential Information, Legal Compliance and Resolution of Disputes, Termination and Signatures.

 

ITSM warrants that SLAs are drafted, negotiated and contracted as per the underpinning contracts and management’s expectation of acquirable IT resources and mapping resources to customer services. SLM ensures that management can deliver the required level of service before any agreement is signed. This is done in discussion with the internal IT departments and the external IT suppliers.

 

The primary task of SLM is to ensure continuous identification, monitoring and reviewing of the optimally concurred levels of IT service as required by the business, in close co-operation between IT services providers and customers. The goal of SLM is to maintain and improve IT Service quality, through a constant cycle of agreeing, monitoring and reporting upon IT Service accomplishments and instigation of actions to eradicate poor service in line with business or cost justification. During the course of business, SLM ensures building sufficient capacity for meeting SLRs.

 

ITIL v3

 

Recently, OGC has introduced new version of ITIL called as ITIL v3. ITIL v3 is a part of a process to enhance and improve the ITIL ideal practices. This is the essence of “Current ideal practice” – defining the frontiers and industry practices, which continuously shift as organisations compete to meet the evolving demands of customers. ITIL v3 is written with a broader context and scope of thinking for ideal practices. The input for the books, reviews and changes comes from a collective global community of IT Service Management professionals and stakeholders during a three-year period. The new approach is termed the ‘lifecycle’ approach, much the same as an IT service in reality.

 

Significant portion of ITIL v2 (earlier version of ITIL) content has been refined and included in ITIL v3. Besides the overall new structure of ITIL ITSM Practices, there are new topics covered in ITIL v3, that haven’t been a part of ITIL in past like strategic aspects, service design aspects, supplier management, outsourcing, service knowledge management system, application design and management, technology structure design and management, service measurement, event management, request fulfilment, access management.

 

ITIL Books

 

ITIL v3 comprises five distinct volumes: ITIL Service Strategy; ITIL Service Design; ITIL Service Transition; ITIL Service Operation; and ITIL Continual Service Improvement. The contents of two most commonly used sets within the previous release, Service Delivery and Service Support, are broadly still present. These were as follows: Incident Management; Problem Management; Configuration Management; Change Management; Release Management; Service Desk; Service Level Management; IT Financial Management; Capacity Management; Availability Management; IT Service Continuity Management; IT Security Management.

 

A sound service strategy is essential in the creation of high calibre IT services. It provides a base upon which to build a successful service management function and ensures that ideal value is delivered to business customers. Service Strategy is a major strength of the new ITIL library. It introduces the service lifecycle and encourages the development of a business perspective. Whether you are a service bourgeois or a business customer, this book guides you through the choices that you need to make to achieve service excellence. It helps focus upon understanding, and upon translating business strategy into IT strategy, as well as selection of the ideal practices for the particular industry in question. It encompasses a framework to build ideal practice in developing a long term service strategy. It covers many topics including: general strategy, competition and market space, service bourgeois types, service management as a strategic asset, organization design and development, key process activities, financial management, service portfolio management, demand management, and key roles and responsibilities of staff engaging in service strategy.

 

Well-designed services play a vital role in realizing a sound service strategy. Effective design contributes towards the delivery of calibre services that meet or exceed customer expectations. Service Design shows how to create valuable IT service assets for your organisation, but within business constraints, such as time and money. It provides a framework for service design that thinks about customer requirements, both now and in the future, while keeping the business view firmly in sight. Service Design provides guidance on the creation and maintenance of IT policies and architectures for the design of IT service solutions. The design of IT services conforming to ideal practice, and including design of architecture, processes, policies, documentation, and allowing for future business requirements. This also encompasses topics such as Service Design Package, service service level management, designing for capacity management, IT service continuity, Information Security, supplier management, and key roles and responsibilities for staff engaging in service design. This also embraces outsourcing, insourcing and co-sourcing.

 

Successfully bringing a well-designed service into the live environment takes efficient planning. It is necessary to deliver new or changed services with the appropriate equilibrise of speed, cost and country while ensuring minimum disruption to operations. Service Transition provides and supports the ‘business as usual’ delivery of the organisation’s stipulations from IT. Service Transition provides guidance on managing the many aspects of service changes, preventing undesired consequences while allowing for innovation. It is essential reading for anyone seeking to deliver IT change with the ideal doable benefit to the business. Service Transition volume covers the longer term change management and release practices. It provides guidance for the transition of IT services into the business environment. Fundamentally, it covers how to create a transition strategy from service design and transfer it to the production (business) environment.

 

Once services have been successfully delivered into the live environment they need to be managed effectively on a day-to-day basis. It is here, at the customer interface, that perceptions about your performance as a service bourgeois are created, and your success will be judged. Service Operation introduces and explains delivery and control activities that support high calibre service operation. Use of the guidance will help to ensure a balanced and flexible approach, setting you firmly on the road to achieving excellence as a service provider. Service Operation covers delivery and control processes with a view to ensuring service stability. Also the monitoring of problems and equilibrise between service reliability and cost etc are considered. It embraces the familiar basics of how to manage services in the production environment, including day to day issues and fire fighting. Ideal practice for achieving the delivery of concurred levels of services both to end-users and the customers are provided herein. This book guides through balancing conflicting goals (e. g. reliability v. cost), event management, incident management, problem management, request fulfilment, calibre management, service desk, technical and application management, as well as key roles and responsibilities for staff engaging in Service Operation.

 

Even with a successful service operation in place, there is still a need to think about improvements at apiece opportunity. This will help protect against losing your competitive edge and will ensure that the ideal doable outcomes are being achieved. Continual Service Improvement focuses on the process elements involved in identifying and introducing a cycle of service management improvements. It provides structure for your approach to assessing and measuring services and helps you to refrain short-terms repairs in favour of a continual improvement in calibre that truly benefits your business customers. Continual Service Improvement covers the processes involved in improving service management within the business, in addition to the issues related to service closure or retirement. It basically describes how to improve a service after it is deployed. The goal of Continual Service Improvement is to align and realign IT Services to changing business needs by identifying and implementing improvements to the IT services that support the business processes.

CONCLUSION

ITIL defines the organisational structure and skill stipulations of an information technology organisation and a set of standard operational management procedures and practices to grant the organisation to manage an IT operation and associated infrastructure. The operational procedures and practices are supplier independent and apply to all aspects within the IT Infrastructure.

ITIL is finally concerned with aligning IT with the business through the whole planning to support lifecycle – that means that the business is finally the driver, not IT. ITIL is a calibre process that is based on continual improvement based on Business needs.

Implementing ITIL is not a swift fix nor will it be simple to implement. It takes a lot of thought, commitment and hard work to successfully change the way the IT organization does business. There needs to be upfront planning, training and awareness, ongoing scheduling, roles created, ownership assigned, and activities identified in order to be successful. Implementation and credentialing the ITIL in ITSM requires knowledge and training. ITIL is intended to be non-prescriptive, anticipating that organizations will have to engage ITIL processes with their existing overall process model.
