Executive summaryThe ability to lower costs while improving agilityand speed of service delivery was once somethinga CIO could only dream of. But the advent of cloudcomputing is making it a reality. However, along withthe benefits have come drawbacks. Virtualizationand cloud computing (private, public, and hybrid)add a much higher level of complexity, and this is

exacerbated by a lack of visibility.This white paper provides an overview of cloudcomputing, including a standard definition, theevolution of cloud models, and the driving factorsbehind cloud adoption. It also explores the challengesthat cloud computing have introduced. Next, itdefines the configuration management system (CMS),looks at the way the CMS and the cloud are related,and discusses the belief that many share: clouddeployments depend on a CMS to be successful. Andfinally, it explains how discovery and dependencymapping is a key contributor to successfully enabling

end-to-end visibility into the cloud, necessary to makethe right decisions for IT and the business.

What is cloud computing?Cloud computing is a delivery model for technologyenabled services that provides on-demand accessto an elastic pool of shared computing assets. Theseassets include applications, servers, storage, andnetworksall of which can be rapidly provisionedwith minimal service provider interaction. The entirepool can be scaled up or down as needed on apay-per-use basis. In other words, these assets cannow be consumed as a service.

Independent research firm, Forrester Research,Inc defines cloud computing as: A standardizedIT capability (services, software, or infrastructure)delivered via Internet technologies in a pay-per-use,self-service way, and breaks down this definition tobetter understand its implications to infrastructure andoperations as follows:

Standardized capability means highlyrepeatable, consistent service delivery. A cloudservice is an easily consumable service, application,

software component, or infrastructure element thatis delivered the same way every single time. Its notcustomized or configured uniquely for each clientthat breaks the economics of the model.

Pay-per-use means paying for resources onlyif you use them. A second core tenet of the cloudcomputing business model is that you pay for theservice based only on your consumption pattern,not on the number of capital assets you will be

dedicating to this service. Nearly all cloud servileverage this model to provide cost elasticity as consumption changes.

Self-service means highly automated. The thimajor differentiation is in how these solutions arprovisioned. Its easy to set up a webpage throuwhich consumers can request services from you.However, thats not how cloud computing works

With cloud, services require provisioning uponrequestusually within five to 15 minutes. Thismeans that to operate a cloud service you haveto automate the provisioning operations so thatthey happen like clockwork, following highlystandardized procedures to ensure that deploymis predictable and done cost-effectively.1

The evolution of cloud modelsTo achieve success in todays fast-paced andconstantly changing IT environments, companies mkeep pace. CIOs grapple with driving IT efficienci

to enhance service delivery and performance, whsimultaneously controlling costs.

While virtualization has enabled IT to maximizeresource allocation and application agility throughconsolidation of applications onto a single physicaserver, it has also added a new layer of complexi

As virtualization has matured, it has necessitated development of virtualized network architecturesknown as cloudsin which physical resources aleveraged to provide on-demand access to variouIT resources. Virtualization software automatically

manages dynamic server provisioning across netwto manage fluctuations in demand for IT resources

Cloud models or architectures today are most oftecategorized based on the way they are used, bason ownership:

External/Public clouds: Cloud assets are shareand service is provided on a pay-per-use basis multiple entities. All assets are owned and operby the provider. Typically hosting of pay-per-usevirtualized servers by third-party cloud vendorsand/or service providers. This model shifts thecapital expenditure (CAPEX) of infrastructure

expansion into scalable operating expenditure(OPEX) managed by a third party.

Internal/Private clouds: Cloud assets are operatedsolely for single entity and may be located on oroff premises. They may be owned and managedby that entity or by a third party. A virtualized ITinfrastructure that hosts services for employees andis managed by an organizations IT staff, shiftingthe IT departments primary role from service andmaintenance to service provider. In a private cloud,all data remains under the full control of the hostorganization, mitigating many potential risks intrinsic

to public cloud deployments. For many enterprises,internal clouds are the most cost effective approachto cloud computing adoption.

Hybrid clouds: The hybrid cloud is a blendedsolution that utilizes parts of both the public andprivate clouds. The integration of on-premises ITinfrastructures and internal cloud applications withapplications and information deployed to a serviceprovider either on a temporary or permanent basis.This model enables an enterprise to serve as its owncloud provider and to leverage an external cloudprovider simultaneously.

Factors driving cloud adoptionThere are many factors driving cloud adoption butmost industry experts agree that its all about servicedelivery. You need to provide technology-enabledservices to your people whenever and wherever theyneed themand you need to do it cost-effectively,securely, and quickly. This is one of the driving forcesbehind the rise in cloud computing.

Cloud computing can provide new levels ofcollaboration, agility, speed, and cost savings forenterprises of any size and type. There is the desire tofind alignment between decreasing or flat IT budgetsand the increasing demand for business-critical ITservices. From a business perspective, the ability toscale infrastructure resources to support rapid growthwithout compromising business efficiency is critical.

Ease of maintenance is another attractivecharacteristic. Because cloud models require lesshardware than comparable distributed computingdeployments, fewer dedicated IT staff members arnecessary to maintain the integrity of the cloudsinfrastructureparticularly during peak hours.

A 2010 research report from Enterprise ManageAssociates (EMA) examined both the benefits andchallenges of cloud computing, drawing from mothan 150 global respondents, 65 percent of who

already had cloud computing deployments, and35 percent of whom had defined and committedplans for cloud adoption within 12 months.2 Ingeneral, the survey respondents were stronglypositive about cloud-computing related benefits,with 76 percent of those in deployment claimingreal or measurable financial benefits from cloud.Figure 1 highlights the most critical drivers for clocomputing adoption.

From an IT perspective, support for rapid provisionand deployment is another attractive characteristicthat appeals to growing enterprises. Because

cloud computing architectures offer nearly infiniteon-demand capacity, new applications can bedeployed immediately without extensive provisionspeeding time-to-market.

Industry analysts agree cloud adoption will continto grow. Recent IDC cloud research shows thatworldwide revenue from public IT cloud servicesexceeded $16 billion USD in 2009 and is forecasto reach $55.5 billion USD in 2014, representing compound annual growth rate of 27.4%. This rapigrowth rate is over five times the projected growth

traditional IT products (5%).3

Challenges introduced by the cloudTypical challenges that enterprises face when movingto cloud solutions. In working with enterpriseslike yours to design and deploy cloud solutions,weve learned quite a bit about the challenges thatcan hinder the success of cloud delivery. Typicalchallenges that you may encounter include thefollowing:

Limitations of a virtual infrastructure: A defining

characteristic of a cloud platform is the ability todeliver applications and all the resources requiredto support them. Many businesses have applicationsrunning on virtual machines, but these are typicallybacked by a database running on a physical server.Todays virtual-only environments, which automatevirtual machine provisioning and monitoring, addressonly a fraction of whats needed to provision acomplete application. They are a stepping-stoneto the next phaseevolving to the cloud. Virtualinfrastructure investments must be extended toautomate provisioning and monitoring of applicationand physical infrastructure, providing end-to-endlifecycle service management and security acrossapplicationsboth virtual and physical.

Closed environments: Other approachesproclaimed as cloud-in-a-box are siloed solutionsthat are isolated and simply cant scale beyondthe box. They limit your choice of applications,operating systems, databases, and hypervisors. Inthis proprietary cloud approach, clients are lockedinto one vendor solution from top to bottom. Oncecapacity limits are reached, such an approach lacksthe flexibility to scale up and down or to incorporate

additional services and resources beyond thedata center. Because of this, you lose one of thebiggest advantages of cloud computing: elasticity.Enterprises require a unified architecture thatbrings legacy investments forward, is open to anyapplication, and can scale resources elastically fromthe best sourceinside or outside the data center.

Cloud sprawl: With multiple types of internal andexternal cloud platforms supporting the enterprise,CIOs face cloud sprawlwith no way to unifycontrol of services, monitor service levels, or achievecompliance. Multiple cloud types, each with different

(siloed) management tools and processes, introducerisks to the business and can quickly consumeresources needed for innovation. CIOs need astandard way to guarantee security, governance,and compliance to protect data, reduce risk, andensure service quality at the right levels for variousbusiness functions.

These challenges underscore the fact that the triedtrue disciplines of IT management are more imporgiven the level of complexity the cloud introduces.The services users access shouldnt be different whorganizations move to the cloud. Although the clomay change how services are delivered to users itshouldnt change what is being delivered to users.

Cloud implications for theConfiguration Management System

As organizations continue to migrate to the cloud,level of usage of automated activities will continueincrease. Once a service is deployed to the cloud,its management within the cloud must be automatiBeneath every cloud there is infrastructure that conof physical servers, network, and storage equipmethat have been the responsibility of the operationsteam and will continue to be. If a cloud is privatethen the operations team has the responsibility formanaging its underlying infrastructure and if a clopublic then the responsibility will fall to the managservice provider (MSP). In any case, both virtual an

physical servers, networks and storage still have tobe mapped and managed and the expected rateof response makes standardized service deliveryand automation a must. At the end of the day, whsuch large and volatile environments are involved,operations teams must be able to make quick decibased on the most updated data. For those teams,the cloud means more virtualization and volatility ithe environments they manage. In addition, tools taccompany the Configuration Management System(CMS) should be autonomous, as much as is possi

Consistency of services is also an extremely imporfactor for successfully operating in cloud environmOrganizations will need to establish configurationstandards and policies for their environment and hthe ability to manage those standards in an automfashion to ensure services are consistently delivere

Defining a CMSInformation Technology Infrastructure Library (ITIL)v3 defines the CMS as tools for collecting, storing,managing, updating, and presenting data aboutall configuration items and their relationships. (See

Figure 2: CMS defined.) The definition can besimplified into collecting, managing, and presentindata about configuration items. A key function of aCMS is simply about collecting configuration datadata providers to supply configuration informatiodata consumers. Federation works behind the scto connect many different data sources.


6/86

Collecting configuration data is an important part ofthe CMS because there are many potential providersof configuration data across an enterprise. Companiesneed to ensure that they leverage reliable sources

of configuration data within their CMS. Effectivediscovery tools can help by automating the discoveryof configuration item data and their dependencies tohelp build a service dependency map. Organizationsneed to ensure automated discovery and dependencymapping approaches are capable of discovering adiverse set of configuration types and relationshipsincluding network, server, application, and storagerelated. A CMS also supports the configurationmanagement process by providing configurationvalidation as part of the configuration managementlifecycle. Finally, a CMS lets you use both serviceand element configurations to navigate the IT dataswamp in order to find the right data you need, in theright service context, to solve most IT problems.

Will cloud success ultimately dependon the CMS?

According to a recent Gartner report: Configurationmanagement is a key process for any IT endeavorincluding legacy IT systems, as well as privateand public clouds or any combination thereof.

Without visibili ty to the configuration of the relevantIT service, IT will not be able to manage the

multisourced cloud infrastructure and software.4

In the short term, the majority of organizationsenvironments will likely continue to be hybrid, ora combination of private and public cloud. Whenoperating in hybrid environments, there will be atendency toward multiple management stacks.

True visibility into the cloud depends on a CMS,especially as organizations move to and operatewithin hybrid cloud environments and multiple stacks.The key to this visibility will be integration to service

providers configuration management databases(CMDBs). Different IT management stacks for theprivate cloud may exist and the cloud CMDB mustintegrate with the integrated or Master CMDB a

depicted in figure 2. The CMS becomes crucial incloud for complete visibility.

According to a recent blog based on data collectfrom research from Enterprise Management

Associates vice president Dennis Drogseth, cloudcomputing seems to be surprisingly good forservice managementboth in terms of technologyadoption and in terms of political and process-reltransformation. This includes technologies likeCMDB/CMS, IT process automation, user experiemanagement and Service Level Management (SLMas well as integrated service desk and chargebac

accountingamong other bellwether technologieor technologies that reflect more advancedorganizational and process readiness. As evidenby figure 3, research data shows that two thirdsof survey respondents believe that a CMS inspiresconfidence when investing in a cloud provider.

The CMS provides end-to-endvisibility into the cloud: Discoveryand dependency mapping,integrations and federation are

key success factorsGartner recommends that IT organizations that abeginning private, public or hybrid cloud projectsshould understand the tools capability (and limitatfor discovering and tracking changes of applicatioand IT service configurations.5

Automated discovery and dependency mapping,integration and data federation are all criticalto providing this visibility. The CMS provides theinformation foundation that enables IT to make betterdecisions as an information broker between providersand consumers of data, and imparts a service context

to the information so that all decisions are madewith a business service in perspective. Integration isa critical aspect especially as organizations beginto integrate to their cloud service provider CMDB(s).Integrations and federation are both integralcomponents of the CMS.

Whether the goal is to virtualize a legacy data center,build a private or hybrid cloud, or consolidate multipledata centers, the key to success is to have a richunderstanding of all the infrastructure componentsinvolved and to be able to use this knowledge to createmove groups that support the effective execution ofthe transformation. Move groups are discrete groupingsof infrastructure that can be moved independentlywithout introducing network latency or other issues thatwill impact ongoing data center operations.

This understanding of the environment must becomprehensive, timely, and should take into accountthe complex web of interdependencies that makeup todays multi-tiered infrastructures. Historically,Data Center Transformation (DCT) projects haverelied on manual processes to create maps thatreflect the transformation target infrastructure and

its interdependencies. This approach has proven tobe insufficient given the size, complexity, and highfrequency of change associated with todays modern,distributed, and multi-tiered infrastructures.

This requires a discovery and dependency mappingsolution that works in complex physical environments,and is compatible with leading virtualization softwarethat provides real-time visibility into the dynamicrelationships between applications and the virtualand physical infrastructure. It automatically maintains

an up-to-date topology map that enables you tounderstand the business service context of virtualcomponents and to quickly identify IT issues that waffect the business.

HP Discovery and Dependency Mapping (DDMA)functions with virtualization software from leadingvendors. For instance, with VMware, HP DDMAworks across the ESX/ESXi, vSphere, vCenter, andvMotion product lines. It gives IT teams visibility inthe architecture of these products so that they canunderstand VMs by location and by hypervisor, atell whether hypervisors are managed or unmanag(See figure 4). It can also discover license serverfeatures and dependencies, virtual resources utilizby VMs, and shared virtual resource pools byhypervisor and virtual cluster.

HP DDMA delivers this insight in various ways. Itcommunicates directly with the operating systemrunning on a VM, or it indirectly discovers the

existence of VMs through direct communicationwith the hypervisorin near real time. It can alsocommunicate with the VMware vCenter (formerly

Virtual Center) management platform to discoverdetails unknown to infrastructure components: datacenter groups, cluster configurations, and licenseserver dependencies.

Event driven discovery functionality in DDMA softwareallows events, for example, movement of applicationsfrom one virtual machine to another, to trigger newdiscovery paths and population of UCMDB allowingalmost real-time visibility into the virtualized environment.

ConclusionTwo facts are indisputable. Cloud adoption is growingexponentially; and visibility into your environmentis at least as, but probably more important whenutilizing the cloud. When utilizing a cloud model,you are making more automated and faster decisionson configurations within your environment than everbefore and that means you need to understand it evenmore completely and fully. This requires visibility intothe cloud.

HP is embracing the cloud and is responding to thechallenges and opportunities the cloud introduces

with existing solutions today and solutions plannefor tomorrow. In fact, HP CMS, comprised ofHP Universal CMDB and HP DDMA addresses ma

of these issues today.

As discussed in the What is cloud computing? sectabove, highly repeatable, consistent service deliveis inherent to the cloud. When consuming the cloudas an abstraction, controlling the timing for whenoperations take place is essential. Change windowand SLAs are very relevant and potential disruptioare a risk. Every cloud has an infrastructure and it be managed either internally for private clouds or the MSP for public clouds. The move to event drivediscovery and the discovery of virtualized environmis critical to a successful cloud implementation.HP CMS is addressing each of these issues.

Make no mistakethe importance and role of theCMS will not be diminished with the proliferation the move to the cloud, it will only become more crto its success.
