or organizations that op-erate beyond four walls, remote servers are a way of life. Data center man-agers tasked with keep-

ing remote servers humming know that offering far-flung users reliable performance without busting the IT budget is the goal.

The good news is that remote serv-ers can be managed today using a variety of hardware-based tools that meet the unique needs of each orga-nization. Many blade systems offer remote management features that give remote administrators Web-based access to diagnostics and nearly total control over the physical boxes. Learn what other technologies get the job done in “Exploring Remote Server Management Options” by Stephen J. Bigelow.

If you’re moving to the cloud in 2011, you’re in luck—new services to help buyers search for independent information on the true costs and benefits of cloud computing are now available. For example, CloudSleuth is a real-time performance monitoring map for cloud services that offers a greater level of detail and interaction.

Other services include SpotCloud, a commodity brokerage service for cloud providers. SpotCloud works by allowing would-be cloud service buy-ers to look for the price they want, while cloud sellers sign up to compete to provide the capacity.

And there’s more where that came from. Check out “New Services Offer Data on Cloud Performance” written by Carl Brooks for help on making the best choices about the cloud.

Virtualization technology may have already saved your organiza-tion money, but how can you get even more out of it? Using management tools as part of your virtual server in-frastructure can definitely boost your return on investment. Find out which features offer the biggest bang for the buck in Frank J. Ohlhorst’s “How to Reduce Virtualization Costs.”

here is no doubt that organizations are embracing server con-solidation to improve efficiency and save

money. But although the footprint of the primary data center may be shrinking, getting essential services and applications to branches and partners usually means deploying re-mote servers. In turn, this means that IT administrators will have to manage and maintain those remote servers quickly and efficiently.

The need for remote servers is driven by the need for business soft-ware performance and practicality. It is at least theoretically possible for a server to provide services for a global user base, but achieving an accept-able user experience at an economi-cal price point can be a considerable challenge.

It’s important to note that remote server management doesn’t auto-

matically imply that an organization deploys distributed servers. An orga-nization may successfully consolidate its servers into a single location, and chances are those servers will be managed remotely on a routine basis.

For example, a complete “lights-out” data center may exist in one place and may be managed entirely from a remote or even a mobile loca-tion. This is exactly the case for Ian Parker, senior Web services adminis-trator for Thomson-Reuters, a busi-ness intelligence company based in Ann Arbor, Mich. The move to shift distributed servers to a central loca-tion and central management started long before virtualization. “For at least five years now, I haven’t touched one of my servers unless I take a road trip out there,” he said.

Remote servers can be managed using a variety of technologies, each dictated by the unique needs of a spe-cific organization. For simple manage-

ment tasks such as software mainte-nance upgrades and status checks, a tool like Windows Remote Desktop is often adequate. But software tools work only as long as the server being managed is operating normally. When an application hangs or the server ex-periences a hardware problem, soft-ware tools can be ineffective.

cards are a bit more foolproof, allow-ing a remote administrator to moni-tor, configure and control more of the server’s hardware elements over a network as if the administrator were actually sitting at the local console.

the promise of mobile devices may seem intriguing. experts already see basic management tools available for some mobile devices, but they also point to sev-eral hurdles that might slow down adoption.

the first concern is the way that mobile devices are integrated into enter-prises. poor control can open up the door to support and security vulnerabilities that might prove disastrous for a remote data center. a second concern is the lim-ited user experience possible with tiny displays. it’s often impossible to replicate the sophisticated gUis used on desktop or laptop systems. this forces mobile application developers to fundamentally rethink the interface for mobile remote management tools. otherwise, users get stuck with a gUi that’s practically im-possible to use.

experts say that mobile devices will probably turn into more of an alert or ba-sic health-monitoring platform for remote server management, leaving laptops and tablets with larger, better displays to handle the detailed server management tasks. p

that server from an administrator’s location over an Ethernet network. An increasing number of UPS systems also include remote management ca-pabilities so that an administrator can cycle power to the server if necessary.

Server virtualization has little di-rect impact on remote server man-agement. “I’m doing that the same, whether that server is 50 feet or 500

miles from me, whether it’s a physical box or a virtualized box,” Parker said.

But the addition of virtualization does provide more control and op-tions than traditional nonvirtualized boxes. One example is live migration of virtual machines (VMs). A remote administrator can move VMs among remote physical servers for mainte-nance or to minimize the impact of a

altHougH tHe contInued evolution of remote management products is reducing the need for human interaction, there are times when you really just need someone’s eyes, hands and technical savvy on-site. here are a few choices to consider:

• Have a staff member travel to the remote data center. this is probably the most inefficient solution because it may take many hours for a person to reach the remote data center before work can even begin. Downtime can be extremely costly for an organization, so this may also wind up being the most expensive solution for human interaction.

• Hire a service provider. when distances and response time requirements make it impractical to put a technician in a car or on a plane, it is often possible to con-tract a local service provider to respond when service is needed. a cost-effective option, the service contract defines response times and can usually reduce down-time significantly. Still, the provider will need access to the remote facility, which can complicate security issues for your organization.

• Talk through less technical on-site staff. this might be a reasonable solution for basic tasks. the local office manager might be able to cycle power to a server rack or perform other rudimentary procedures with telephone instructions from the remote it administrator. this can vastly reduce the need for staff road trips or third-party service calls.

• Reduce the need for human interaction by developing a comprehensive remote management architecture. evaluate the capabilities and limitations of your remote management tools and consider adding or replacing tools to expand on needed features. weigh the costs of managing product deployment against the benefits and savings of adding those capabilities to the remote data center. p

remote server reboot. Similarly, new VMs can be provisioned remotely with the same speed and ease that is experienced locally. Ultimately, virtu-alization adds important flexibility to remote management, but the underly-ing goals of remote server manage-ment remain unchanged.

ReInIng In Remote seRveRsLatency remains a significant issue, and any connectivity problems be-tween the servers and administra-tor can make remote management slow or even impossible. Yet experts generally agree that the various tech-nologies used for remote server man-agement are relatively mature and robust today. Tools can often provide warnings and alerts that allow ad-ministrators to take action before a server failure actually occurs. But con-fidence in the overall state of remote server management tools is where the agreement ends. The actual choice of tools can be contentious.

For example, some experts prefer software tools like Remote Desktop Protocol in Windows for basic server maintenance tasks. Other experts say that integrated solutions like DRAC and iLO may be better because they’re bundled with their respective servers and covered under the serv-ers’ warranty. Still others opt for third-party remote server management tools because of their ability to gather and present a broader perspective of the remote environment. Similarly, KVM over IP can be a powerful man-agement platform regardless of the

operating system or data center envi-ronment, but it may not be appropri-ate for every situation.

The choice of management tools is really minor. The bigger problems with remote server management are actually attributed to people and their response times rather than technol-ogy. “Anytime you’re dealing with something that you can’t walk up

to and touch, you’re at the mercy of other people,” Parker said, adding that other people’s schedules, differing work priorities and lapses in inter-personal communication can make delays in response time seem more painful than they might actually be.

In many cases, sound policies and measurable procedures can help mini-mize skewed perceptions and ensure that on-site personnel address server issues in a timely manner. If a third party provides the remote service, chances are that the service contract or service-level agreement already incorporates a well defined escalation path and measurable response time windows.

Perhaps the biggest gap in remote server management technologies is in automation. For example, Parker said that many of his remote servers expe-rience extended idle time during off-peak hours. Better automation sup-port from remote management tools might allow organizations to migrate more idle VMs onto fewer physical hosts, power down the additional physical servers during idle hours and then power up those servers and reallocate the VMs in preparation of peak demand hours. Parker said the idea is there, but more development is needed in that aspect of remote server management products.

tHe futuRe of Remote seRveR managementRemote servers are not going away any time soon. The simple fact is that server densities are increasing at a faster pace than the power and cooling resources available to handle them. With power and cooling hit-ting hard limits, organizations cannot deploy new equipment as quickly and effectively as they might like. So the move to multiple data center loca-tions provides growth potential that might be impossible with a single cen-tralized production data center.

“It’s easier to deal with 10 10,000-square-foot data centers than one 100,000-square-foot [data center] because you’re probably not going to fill up those smaller spaces,”

Parker said, adding that smaller spaces are generally allotted to com-pany divisions or departments with limited computing needs. And new deployments at one location will not affect power and cooling demands at other locations—reducing the impact of changes in production environ-ments.

Virtualization is not required for remote server management, but it is playing an important role in the future. Server consolidation reduces the number of physical boxes, which eases the time and effort spent man-aging them. Companies can select larger and more powerful servers capable of hosting more VMs than a large number of basic “commodity” boxes, usually resulting in more effi-cient spending. The biggest challenge is managing computing resources and data protection processes as new VMs proliferate across data centers.

Remote server management tools are remarkably well developed, but expect to see continued refinement and added capabilities such as report-ing and automation. “Increasingly, the hypervisor doesn’t matter so much. What matters when you’re looking at a virtualization vendor is what kind of management tools are they offering you,” Parker said. “The vendors them-selves are talking more about their management tools, and the options they give you to do things with your virtual servers are going to be pretty important,” he said. p

New Services Offer Data on Cloud Performancea new wave of useful services is helping buyers search for inDepenDent anD realistic information on what clouD computing actually Does anD what it costs. By CaRl BROOkS

ublic cloud computing services like Amazon Web Services (AWS) have definitely arrived for some market seg-

ments, most notably Web operations and Web applications. In their wake, interesting developments are now cropping up, like CloudSleuth, a real-time performance monitoring map for cloud services, and SpotCloud, a new stab at cloud brokerage.

This new crop of supporting char-acters is starting to grow as buyers search for more valuable, indepen-dent and realistic information on what cloud computing actually does and what it costs. Cloud benchmarks are already available from sites like CloudHarmony and others.

Now CloudSleuth, which launched late last year, uses Compuware’s ap-plication performance monitoring tool Gomez to analyze publically available data from the Internet.

“The fact that they’re doing this as an open platform is really encourag-ing,” said James Staten, Forrester Research Inc. vice president and in-frastructure expert. Cloud monitoring sites aren’t really new—there are sev-eral networking monitoring sites that track cloud availability—but Cloud-Sleuth offers a greater level of detail and interaction.

The site not only shows a dizzying array of performance statistics, but it also allows users to test-fly applica-tions and see how performance might be affected around the world. There are forums for discussion and quite a few tools that just about anyone de-veloping a Web service or looking for detail on what cloud can do for them will find interesting.

For instance, CloudSleuth makes it so performance can be monitored at many different providers around the world. It’s sort of a stock ticker show-ing where a given application might

work best. Users could use the site to route around areas that have traffic holdups, and vendors can tailor their deployments to where there is more demand—all in almost real time.

compuwaRe’s plan foR cloudsleutHSo what does Compuware Corp., a venerable mainframe solutions firm that most people wouldn’t associate with cloud computing, get out of it?

It’s good old-fashioned boosterism, said Doug Willoughby, Compuware’s director of cloud strategy. Compu-ware and the other companies that partnered on CloudSleuth—including Cisco, Japanese firm Internet Initia-tive Japan Inc., a network solutions provider, and OpSource—all have a vested interest in encouraging aware-ness, visibility, transparency and growth in cloud services.

“[Cloud computing providers] are competing against non-consump-tion—not each other,” Willoughby said. Compuware’s own custom-ers are turning to cloud in increas-ing numbers, which doesn’t hurt its bottom line too much. Compuware doesn’t care if customers run its prod-ucts on Amazon or anywhere else. But cloud is a major growth opportu-nity, Willoughby said, and launching CloudSleuth eases user confusion about what’s out there.

CloudSleuth is the only company that can provide this kind of visibility in the cloud, Willoughby said. Gomez shows users exactly where and how most website transactions go—a vir-

tual traffic map for the world’s Inter-net consumption.

“If we go through the 50,000 transacts we monitor on an hourly basis and break it down, 32% of sites have at least one call that ends up at Amazon or [Elastic Compute Cloud]. Essentially, one in three applications has at least one service that starts in AWS,” he said.

That makes it important for Com-puware users to be able to keep track of what’s happening and where—and Amazon certainly doesn’t care to broadcast information—so Cloud-Sleuth fills the gap. It costs Compu-ware little, relatively speaking, and gives users peace of mind about dip-ping into the cloud, Willoughby said. The site is hosted on GoGrid.

brokerage service for cloud providers. Cloud users sign up on the buy side to look for the price they want, and cloud sellers sign up on the sell side to com-pete to provide that capacity.

The brokerage is modeled on Ama-zon’s Spot Instances, where AWS us-ers bid for instances that go up and down in price, but SpotCloud aggre-gates multiple service providers into its marketplace. There’s one major limitation at the moment, however: This is Enomaly’s cloud only. Cloud providers using other technologies need not apply.

“I think when [Enomaly] supports at least one more implementation, it’ll be interesting,” Staten said. He ap-plauded the idea of an autonomous clearinghouse for cloud but said Spot-Cloud will wither if Enomaly can’t bring more providers into the fold.The real technical feat will be to make cloud delivery seamless across differ-ent technology platforms, but that will be a long-term proposition.

wHeRe to get moRe cloud bang foR youR buckAnother thing that’s changing rapidly is the era of price exclusivity or the abil-ity to charge whatever feels right rather than facing external pressures. This lack of competitive price pressure, some observers say, has kept costs for cloud services high.

Web development shop GoCipher said it has a rudimentary answer: Its new Cloud Price Calculator uses what the company calls a Cloud Price Nor-malization (CPN) index to show the

kind of cloud resources users will get for their money. GoCipher President Daniel Berninger said on his blog that there are giant, unjustifiable differ-ences between what should be essen-tially equal services, such as compute, memory, storage and bandwidth. To show this, his calculator looked at five providers and their service offerings.

It quantified the parts of each offer-ing, added them up and divided that into the monthly price. That num-ber—monthly fee divided by cloud re-sources delivered—was then divided into $1,000, returning the CPN index that can show how much cloud you’ll get for $1,000 per month.

GoGrid fared poorly, with one of its smaller cloud services costing $721.90 per month but receiving a CPN of just 5.54. On the other hand, SoftLayer Technologies scored a 58.57 for its four-core Public Cloud CloudLayer service, which costs $309 per month. Berninger thinks some of the lack of value is because of the hid-den—or at least underemphasized—costs of bandwidth in cloud usage.

To prove the point about value and price, GoCipher resells three offerings from DomainGurus that match up with three different AWS offerings and significantly undercut Amazon’s prices on each. It’s important to note that it’s a monthly charge, not hourly, and runs just two images—Windows and Cen-tOS—so it’s not exactly a true cloud offering. Nor is it on par with the range of features that AWS now offers, but the point is made. There’s less and less room to hide, cloud providers—the market is coming to get you. p

irtualization got its foothold in data cen-ters based upon one simple idea—doing more with less. With

fewer physical servers to manage, vir-tualized data centers are simply more efficient. That efficiency can deliver measurable savings because fewer servers mean a reduction in power usage, physical hardware support, square footage and cooling.

But the savings shouldn’t end there. A number of options, enhancements and capabilities are available today that can help data center managers increase virtualization’s return on investment (ROI) while reducing its total cost of ownership.

Virtualization is touted as the tech-nology that offers significant savings, but it is actually server consolidation that really reduces costs. Virtualiza-tion is just the technology that makes consolidation viable. So if consolida-

tion has already saved your organi-zation money, how can you squeeze even more out of the technology?

sHIftIng tHe focusThink of it like this: If you shift the fo-cus to overall data center operations and consider how virtualization has become part of the actual infrastruc-ture, then it becomes much easier to identify elements ripe for improve-ment. It’s those areas that may be able to offer greater savings.

Virtualized servers and the related infrastructure pose a significant man-agement burden, which does not end with implementation. Data center staff has to worry about other issues, such as provisioning, backup, resil-iency, availability and failover. To date, many have relied on a combination of bundled tools, third-party applications and gut instincts to keep data centers with virtual servers up and running,

which is not an ideal approach. These management areas are prime

targets for savings. Ideally, manage-ment of virtual servers should be inte-grated into the overall management of the data center, eliminating the vari-ous silos of nonintegrated manage-ment tools.

To make management a little easier, vendors that provide management tools have enhanced their offerings to address the unique requirements of today’s virtual servers.

There are some critical capabilities that a virtualization platform manage-ment tool should offer—most impor-tant is the ability to monitor the per-formance of virtual machines (VMs) in real time.

keepIng tabs on peRfoRmancePerformance monitoring can reduce costs in several ways—administra-tors can use it to determine the load of a particular physical machine, which allows them to decide if more servers can be consolidated onto the hardware. Monitoring performance can also indicate if there are avail-ability problems, so administrators can address them before they be-come detrimental to data center ef-ficiency.

One of the more critical aspects of performance monitoring comes from the ability to auto-spool or provision additional resources under times of high demand. Here, third-party VM monitoring tools, such as those avail-able from SolarWinds and Manage- Engine, can launch additional virtual

resources to meet load-balancing needs. That capability allows admin-istrators to further reduce a physical server footprint by allocating shared re-sources on a demand basis, which can

reduce capital expenses even more.Management tools that offer a sin-

gular dashboard view of virtual op-erations can be valuable time savers. With a quick glance, administrators can check the status of virtual serv-ers and other devices, allowing them to plan resources more effectively or respond to problems quickly.

Dashboards should also incorporate drill-down capabilities, which help re-duce the time it takes to troubleshoot a problem. Saving time on problem-solving helps to improve ROI on many levels—not the least of which is staff-ing costs.

Management tools can lead to other savings related to maintenance tasks. Many of the management tools on the market integrate with the APIs from the leading virtualization platform vendors.

That integration helps administrators automate backups, apply patches and perform settings changes to reduce ser-vice interruptions.

What’s more, the integrated nature

seveRal fRee tools are available that can give data center administrators a quick start for exploring potential areas for savings under a virtual infrastructure:

• VM Monitor is a utility from network management vendor Solarwinds inc. VM Monitor is designed to work with VMware infrastructures, and it offers monitoring capabilities as well as analysis and reporting.

• ManageEngine’s VM Health Monitor offers real-time monitoring of VMware eSX and eSXi servers and includes the ability to monitor guest oS resources as well as network bandwidth usage. those managing virtual servers will find the in-formation provided valuable—at a price that can’t be beat.

• Virtual Server Discovery Tool from Spiceworks inc. offers a quick and easy way to find hardware and run hypervisors across the data center. the utility is an effective way to build an inventory of virtual servers, which includes configura-tion information of the hardware and detailed information on each virtual machine (VM).

• Veeam Monitor Free Edition is another example of a free utility that brings some basic management to the virtual server market. the product offers busi-ness-centric monitoring capabilities, which translate to performance monitoring, alerting and reporting for VM groups based on criteria such as business unit, de-partment, location, purpose, service-level agreement or any other defined criteria. this ability to perform business-centric monitoring helps to identify the business impact of a virtual infrastructure’s performance and respond accordingly.

these free tools should be a good starting point for data center managers looking to explore management and administrative capabilities for virtual server environments. with that knowledge, picking the tools and techniques needed to improve the return on investment of consolidation and virtualization should prove to be a straightforward process. p

of management tools helps to ease change management tasks. Acciden-tal changes are avoided, thanks to comprehensive logs, reporting and assigned roles. Recovery from failed patches is simplified, and administra-tors are able to keep better tabs on operations.

capabIlItIes tHat Reduce costsUsing management tools as part of a virtual server infrastructure can defi-nitely boost ROI, but it’s important to choose a management platform with specific capabilities that can help gen-erate savings. Look for the following features:

pp end-to-end mapping: This feature has the ability to map applications and includes logical connections to the physical infrastructure.

capacity planning:pp Pick a man-agement platform that can iden-tify underused hosts and systems to prevent wasteful physical ma-chine and VM sprawl.

performance monitoring and pp

reporting: Real-time dashboards should identify performance bottle-necks, trigger scripts, provide alerts

and present historical information.

Data classification:pp This feature shows how space is being used and automates the management of unused space.

Server consolidation reporting:pp Use this to simplify the identifica-tion of virtualization candidates and promote additional consolidation.

Server capacity planning:pp This can decrease costs for support and utilities by reducing server sprawl and by providing insight into future needs.

Server monitoring and reporting:pp Real-time monitoring of physical and virtual servers offers alerts when usage and status thresholds are exceeded.

Using these features as a guide, deploy management tools that are integrated with network manage-ment utilities. With a reliable set of management tools as part of a virtual server infrastructure, data center ad-ministrators will be able to get a jump on possible problems, reduce down-time and plan for the future while re-ducing operation costs.p
