Why the Cloud Isn’t for Everyone

cloud

Moving infrastructure to the Internet is the right thing to do, particularly for companies starting from scratch and for those seeking lean, mobile operations, writes Elsa Wenzel in a blog featured on Computerworld. Yet, she maintains that the cloud isn’t the solution for every business. As an example, Wenzel holds up The Grand Opera House in Wilmington, Del., which suffers from frequent network and Internet outages. Without an Internet connection staff wouldn’t be able to process ticket orders if its business was run entirely on the cloud. READ MORE »

Switch Blade: Migrating to Blade Servers

our beautiful site

Small-scale blade servers can slash small business energy and cabling costs and dramatically lower your server footprint. And installation and management are fairly straightforward. But are these reasons enough for a small to midsize business to make the move to blades? Blades are self-contained servers designed for high density. A blade enclosure can hold multiple servers. These servers appeal to small-business demand to integrate data servers into a single chassis, says Scott Tease, IBM worldwide product manager for blade at IBM of Armonk, N.Y. The capability to integrate more functions onto blades makes for a smaller footprint while providing the same services as standard rack-mount servers, says Steve Gillaspy, group manager, blade system division, at HP of Palo Alto, Calif. The decision to migrate in all or part to blade servers depends on a variety of factors that must be weighed byindividual business owners, Tease says. Assessing blade applications and savings The small-scale servers are particularly useful for certain applications like Web hosting, server virtualization, and cluster computing, he adds. Small businesses that need those capabilities should definitely check out blades. But if the costs to migrate don’t make sense for your company, migration should be put off, he adds. To assess migration savings, first look at power and space needs, says Frances Lam, blade product manager at Sun Microsystems of Santa Clara, Calif. Luckily, most vendors provide online assessment tools and calculators that can help assess costs, space needs, and tools associated with the move to blades. Many blade providers have also partnered with third-parties who conduct on-site thermal and power analyses, he adds. The servers might reduce the amount of IT staff needed to manage them. Blades can be easy to install, he adds. A small business may not need specialized IT support. While a standard server needs power cords and network cables, the self-contained blades don’t have need for much wiring. But just because the blade enclosure can reside in a room the size of a closet doesn’t mean small businesses with limited real estate can simply open a closet door and slip the blade enclosure inside, Gillaspy says. “There is still the law of physics for every room,” he says. “Understand what your room is capable of in terms of heat and power because you’ll need to stay within those parameters.” The cost of blade servers Also, the cost of blades as compared to traditional servers can be pretty close. Savings come when energy costs are factored into the equation, Tease says. Prices for the blades range from $7,000 to around $10,000. An enclosure to hold the individual blades will need to be purchased. They run from around $15,000 to $20,000. Standard servers can cost from around $8,000 to around $10,000, though no enclosure is necessary. Small and mid-sized businesses that do opt for blades are luckier today than in years past. Vendors have been stepping up the marketplace with blade offerings catered to the small business. These blades are simple to install and runs on office power, Lam says. Sun has developed a range of blade products for the small and mid-sized business data center, Lam says. At IBM, the BladeCenter S is tailored to small and mid-sized businesses looking to consolidate and simplify their server infrastructure, Tease says. SIDEBAR: Blade Migration Assessment Tools Some blade vendors and industry analysts offer online assessment to tools to help you determine whether blade servers make sense for your business. Such tools can be found at: IBM Blade Center Assessment Tool

Tech Talk: IT Service Firm Upgrades Support

PlumChoice, a nationwide remote technical services firm headquartered in Billerica, Mass., helps troubleshoot IT problems for the home, home office, and small business customer. Rich Surace, senior vice president of operations, tells IncTechnology.com that by upgrading to an appliance-based virtual IT support technology the company is helping resolve a growing variety of problems with computers, PDAs, and other devices on a variety of platforms. Elizabeth Wasserman: What does PlumChoice do? Rich Surace: PlumChoice is the nationwide leader in providing trusted remote technical services for the home, home office, and small business on a 7/24/365 basis throughout the U.S. and Canada. We have comprehensive plans and service options, from simple one time service fixes to a complete protection plan that is charged monthly. We help our clients with computers, networks, cameras and CE devices, hardware and software needs. We also have multiple channels of distribution and we support a variety of channel partners, including telcos, ISPs, and others. Wasserman: What was wrong with your IT support that you needed to upgrade? Surace: It wasn’t what was wrong but what was missing. What was missing was being able to extend our platform to provide a broader range of tech services. We had some technical challenges that did not allow us to provide certain types of support beyond the basic Windows and Intel — or Wintel — systems. We wanted to be able to extend our support to Macs and PDAs but until about 12 months ago we only had the ability to provide services to more traditional types of machines.  This is a great competitive differentiator for us. Wasserman: So what did you do? Surace: We upgraded to something called the Bomgar Box. It’s an appliance-based software for virtual support that allows companies to connect to remote clients and co-workers via the Internet anywhere in the world in seconds. It’s a remote tool that has features such as collaboration and extension of services to devices where traditional remote tools haven’t gone yet — such as PDAs, digital cameras, and cell phones. We have two server-based units that reside in our co-location facilities through the U.S. We’ve now incorporated it into our support enterprise. It’s one of many tools we use. The nice thing about it is the appliance resides in your building. We have control of how we deploy it and where we use it. It’s now part of our overall service delivery platform, which we call SAFELink. Wasserman: What benefits have you realized? Surace: We can now get access to other devices that we didn’t have access to before, such as Macs, PDAs, consumer electronic devices, such as your camera or cell phone or other mobile device. And our Partners can begin to create really unique services for the market.  People use their cameras on their mobile phones all the time and they don’t necessarily know how to transfer pictures, or sync their schedule between PC and PDA. Many of them also have MP3 players in their phones. Consumers use these devices for data, pictures, e-mail, voice mail, etc. The PDA is the handheld computer of the future. When customers have a problem with their device, we now can extend remote service to those devices and platforms. 

How to Simplify IT and Unlock Resources

Businesses today are operating in some of the most challenging financial conditions — little access to credit, soaring energy costs, and record declines in consumer spending and confidence. And while some businesses are closing their doors, for those that stay open this is an opportunity to employ some survival techniques, whether they need it or not. Now is the time for businesses to reassess their landscape, particularly their information technology infrastructure, and determine what’s helping — or hurting — the bottom line. Trading spaces While servers often account for a large portion of a company’s IT budget, many companies are only utilizing 10 percent of the server space — not exactly the best return on investment. Furthermore, it’s estimated that for every dollar companies spend on server hardware, they also spend anywhere from $7-12 on maintenance. This includes software licenses and power to run the servers, air to cool the servers, and employees to manage the servers. It may also include maintenance fees to cover broken or damaged equipment. It’s easy to see how expensive unused server space can be. Therefore, it’s recommended that businesses move toward server consolidation, which not only decreases operating costs, but also aids in disaster recovery operations. By hypothetically reducing 50 servers to five, companies increase the storage usage while minimizing operational costs, and in the aftermath of a disaster, rather than duplicating 50 servers with minimal usage, companies only have to duplicate five at near full capacity. Less is more There are several options for managing a company’s servers, including physical and virtual consolidation. It’s not uncommon for a business to have multiple servers in remote locations. Some companies can opt to physically take all servers and move them to one central location, thereby reducing storage fees and costs to maintain data centers. Data center costs are compounded heavily by IT power costs, making it likely that power and cooling costs will overtake hardware fees in the next few years. So virtualization is often the next step beyond physical consolidation, unlocking untapped server storage and networking resources. Virtual reality Through virtualization, a company can take 50 servers running one application each, and consolidate to five servers with 10 applications on each. Such consolidation sets the stage for cost savings moving forward including reduced hardware expenditures and server management. However, not only have companies utilizing virtualization processes reported savings on operational expenses, they’ve also reported reduced manual errors, increased new application deliverables for business mobility, and less manual maintenance. Most importantly though, virtualization allows companies to reduce capital expenditures and focus on what they do best — encouraging robust competition, improving customer experience, and reducing risk. Multiple servers sprawled across multiple locations increases the difficulty of managing data and the accompanying large network connections that can compromise network security. Moving forward Whether a company seeks to physically consolidate its servers or establish a virtual network, the key is to partner with a vendor that works with companies that are the size of where they want to grow to, rather than the size they are. These vendors can aid in keeping costs down by charging for what you need today, while providing the ability to expand to where you will be in the future. While challenging economic conditions may complicate long-term planning, there are always ways for companies to add value, especially within the company’s IT infrastructure. The key is ensuring that the company’s infrastructure remains flexible enough to adjust to any potential change. Moving forward with effective IT simplification measures prepares companies to cut costs and improve efficiency. In addition, by effectively cutting costs, IT departments can now focus on leveraging emerging technologies that may previously have been unattainable because of budgetary restrictions. Now is the time for business leaders to take a good look at their business landscape and determine what’s helping — or hurting — the bottom line. Mike Gorsage is the National Technology Practice Leader for Tatum LLC. Tatum is the nation’s largest executive services firm, providing financial and technology leadership to businesses of any size.

Has the Greening of IT Gone Too Far?

Everyone seems to be jumping on the green bandwagon, which is great for our environment, but how do we know when buying green is overkill? “Green IT is an oxymoron,” says Simon Mingay, an analyst with Gartner Research. “There’s no such thing, but with more efficient tools available, you will more than pay back any incremental costs.” Studies show that businesses want to be energy efficient and that when it’s time to replace old equipment, whether it is a server or a desktop, IT managers make their replacement the energy efficient choice. However, most businesses do not replace a good system even if it is not energy efficient or if it still has many years left in its life cycle. Mingay agrees that you’re better off hanging on to the old equipment if it is reliable, and he says when it’s time to replace hardware “then making energy efficiency part of the buying criteria is absolutely critical.” Businesses need to look at achieving energy efficiency in both their desktop and data center environments without compromising budgets and shrinking their return on investment. Greening of the data centers In the data center, many companies choose a virtualization solution, which may include integrating a software solution like VMWare with existing servers or may require buying larger servers to give power to the virtual machines. Energy efficiency can be achieved depending on how many servers there are. Consolidating servers is another green solution which reduces loads and ultimately saves costs. BDNA Corporation in Mountain View, Calif., helps companies save energy by using their GreenScan technology to run a server inventory. When the scan is complete it reveals how much power each server consumes, which determines the new server configuration. If new servers are necessary, then the scan takes into account the company’s current footprint and monitors the migration of the new location’s future equipment purchase. Companies can deploy thin clients and use CPU power throttling for their high-end servers, where the servers throttle down during low use time and don’t waste power. Data center solutions do require purchasing additional hardware and they do require more time to implement. Steve Brasen, analyst at Enterprise Management Associates recently conducted a green IT study which revealed that some data centers can’t reduce their power consumption since they need to be up and running 24/7. In reference to virtualization and hardware upgrades, Brasen says, “You should upgrade hardware because it’s time for more efficient computing, and not for just having an energy efficient solution. Choosing virtualization in order to go more green shouldn’t be the primary reason for deployment.” Greening of the desktop area In the desktop area, using power management tools such as turning off the machines at night, using spin down drives or hibernation tools lowers costs so companies don’t need to purchase new equipment. Brasen in the same green IT study found that when power management techniques were implemented in the desktop area, there was an average of 19 percent reduction in power. He also found that using laptops cost $23.26 in power consumption per year, versus desktops costing $149.10 per year. “So for 10,000 deployed desktops, which would consume 1.5 million in energy costs, and laptops, which cost $232,600, you could save $1.3 million annually,” he concludes. ”Going green is the great umbrella of social responsibility and reducing company cost,” Avanish Sahai, vice president of BDNA marketing says. To achieve energy efficiency in the desktop area, “There’s simple stuff that can be done with dramatic effect. Get a policy with automated power management to turn off your computers and monitors and see a savings of 22 percent in IT costs.” Sahai adds that companies also need to educate their employees on how to use Windows’s hibernation controls and then set a policy and monitor it. Mingay suggests companies check out Electronic Product Environmental Assessment Tool at EPEAT.net to find out which monitors, desktops, and notebooks are the best green choice as rated by the Energy Star 4.0 rating system. Obstacles to green IT The largest obstacle to implementing a green IT initiative is the budget and responsibility split between the facilities department, which handles the power budgets and the IT department. Sometimes a good green policy gets stuck waiting for the right data and implementation to make it happen. Ultimately, the CEO needs to provide the overall vision of green IT by implementing green governance, or corporate social responsibility bodies to oversee multiple projects across departments. Mark L. Cavaliero, CEO of SyTec Business Solutions in Raleigh, N.C., a network integrations firm, says he makes his green IT decisions by listening to his vendors, his clients, and his team of engineers. He also considers his budget. “We don’t like to waste anything and there’s also an economic incentive to help clients save money and to make our employees more productive,” Cavaliero says. Regarding green IT, “It seems that the economic and benefits to society have lined up.” Where green IT is headed Brasen predicts virtualization will be the number one data center solution to achieve green IT over the next year and he also emphasized that the 19 percent average saved in the desktop area could be even greater. He states that opportunities do exist in both the data center and desktop area and that more companies will realize that you can reduce power consumption and produce ROI. Implementing a green IT policy is no different from any other networking or security implementation. Both involve a thorough inventory of all hardware and software assets and both require the CEO to communicate policy and goals by example and leadership. Companies shouldn’t rush to buy green equipment without first checking the equipment’s agility first just as they shouldn’t implement an ad hoc green policy that doesn’t reach all areas of their organization. But by adopting power management strategies and replacing equipment nearing the end of its lifecycle with a more energy efficient models, companies can reap the benefits of sustainability, social responsibility and cost savings.  

Before You Virtualize Servers: A Checklist

our beautiful site

In the Fall of 2007, the IT department at Campbell Clinic Orthopaedics faced a problem: several servers were due or overdue for replacement, so the clinic would have to purchase up to 10 new ones during the coming year. “We could have gone the traditional route and bought 10 servers,” says Justin Lauer, director of IT. Instead, the clinic bought three physical servers and installed virtualization software on both new and existing machines. Today, Campbell Clinic has 20 to 25 virtual servers running at any given time. The number varies because Lauer and his team create extra virtual servers as testing environments for new software, and then delete them when they’re through. Virtualization has worked out great, he says. “We did it because of an aging infrastructure, but we all got the benefits of consolidation and the flexibility to create new servers at will. And we didn’t realize until we did it how good it would be for our disaster recovery plan.” Since a virtual server is stored as a single file, it’s easy to reload that file on new hardware and get it up and running in case of need, he explains. But while virtualization brings major benefits, it also comes with a few challenges that should be addressed right from the start. Before you virtualize, make sure you have answered the following questions: 1. Will our servers need more RAM? The answer is almost certainly yes. “RAM is the key. I can’t stress that enough,” Lauer says. “RAM is the most used resource in a virtual environment, so don’t expect to get a server and throw a couple of gigabytes of RAM in it. You’re going to max out the RAM. It’s common for servers hosting virtualization to have 32 gigabytes.” 2. What about other resources? For x86-level servers (the low-end, desktop-computer-like servers most small companies use), virtualization can strain more than just RAM. “You have to plan for all the different hardware requirements,” Lauer says. In addition to RAM, these could include more processing power, network input/output (I/O) capacity, and bandwidth. “If you’re trying to run 10 virtual servers on a physical server with only two network cards, that will create a bottleneck,” he says. 3. Are we prepared to cool “hotspots”? One of the best arguments for virtualization is reduced power consumption: fewer physical servers will draw less power, and also require less cooling. While all this is true, your newly virtualized servers will be working much harder than your servers did before, and this can create isolated “hotspots” where temperatures can rise rapidly. “The amount of heat you need to dissipate can increase by factors of 10, especially if you’re putting in blade servers or high availability hardware,” says Bob Waldie, CEO of Opengear, which provides infrastructure management. “You were using hundreds of watts, and now you’re using kilowatts on that one device.” 4. How will we deal with hardware failures? “When you had a larger number of servers running one or two applications each, a hardware failure would only have removed a little piece of your functionality,” Waldie says. “When you have eight or 10 servers running on one physical device, you could lose a lot more mission-critical function if the hardware goes down.” This is why many smart companies put in high availability solutions, with failovers in place in case a server does down, at the same time that they virtualize. 5. Can IT staff deal with increased complexity? “If you had 25 servers before, and now you have far fewer, it may seem like you’ve reduced the complexity,” Waldie says. “In fact, you’ve increased it. You still have exactly the same number of servers running, only some of them are now virtual. In addition, you have the virtualization software itself to manage.” How will your team cope? Training is the best strategy, according to James Staten, principal analyst, Forrester Research. “Make sure whoever will be responsible for the virtualization software is certified on that product,” he says. “If not, you should send them for certification.” 6. Are we ready for the future? Waldie advises reviewing the physical environment and architecture you’re currently planning to use for virtualization, with a view to the next three years. Will your racks and other equipment be able to handle the densities, workload and cooling needs you’re likely to encounter, especially if your company is growing? “Even though adoption of virtualization is ramping, the tools don’t generally work across platforms,” he says. Yet mergers or other developments may force you to work with different brands of virtualization software. “You should get some expert advice about how to architect your virtualized system to gain flexibility,” he says. “It seems simple, but it’s not.”  In time, it will probably get easier to work with two or more brands of virtualization, and “platform-agnostic” tools will be developed, he says. “The thing about virtualization is, it’s still very early days.” SIDEBAR: Want to Try Out Virtualization Software? To truly reap the benefits of virtualization, you’ll want to install a hypervisor that replaces the operating system as the “bottom-of-the-stack” on your server, and runs everything in a virtual environment. If you need to quickly add a virtual server to an existing setup, or just want to give virtualization a try to see how it works, other software options will allow you to add one or more virtual servers to an existing setup. Many providers offer low-end versions of both types of software as a free download. Here are just a few: Citrix XenServer: Built on the open-source Xen standard. Microsoft Hyper-V: Released in June, works with Windows Server 2008. VMware Server lets you add one or more virtual servers to an existing server. VMware ESXi is a hypervisor.

Alternatives to Microsoft Exchange

our beautiful site

Many small and mid-sized businesses rely on Microsoft Exchange servers and services to manage e-mail and collaboration processes. But there are a growing number of alternative products on the market, each trying to chip away at Microsoft’s market share by delivering similar functionality for less money, making its software available on a non-Windows platform, or offering unique products and services not found in Microsoft Exchange. What Microsoft Exchange is Developed by the Redmond, Wash. software giant, Microsoft Exchange is the leading messaging and collaborative software solution, widely embraced by both small and mid-sized businesses and larger enterprises. Installed on a company’s premises, this server-based software is used for managing e-mail, calendaring, contacts, and tasks — all part of the Microsoft Office suite on the client end. Exchange also supports mobile and Web-based access to company info. Additionally, Microsoft’s offerings offers data storage, shared folders, and unified messaging solutions — such as accessing your voicemail box via e-mail or listening to your e-mail over the phone. “I wouldn’t say it’s the ‘de facto’ server solution but it’s certainly the leader in both revenue and the number of organizations,” says Mark Levitt, vice president of collaboration and enterprise 2.0 strategies at the Framingham, Mass.-based IDC research firm. “Because Microsoft has established itself as a provider of many applications and products, companies see value for a single source that offers a variety of management solutions, all using the same underlying Windows platform,” Levitt says. “Plus all upgrades and patches for multiple products can be handled by one company, which is very appealing.” The trouble with trying to compete According to Gary Chen, a senior analyst for enterprise research at the Boston, Mass.-based Yankee Group, e-mail management is “pretty much a two horse race” between Microsoft Exchange and IBM Lotus Domino and Notes. “Exchange is definitely the leader — they’ve come up a lot over the past few years — though [IBM] Lotus Notes has really put a lot of effort into making a resurgence, and they have some interesting things on their roadmap,” says Chen. “Exchange can be hard to manage and the alternatives are cheaper, so [competing products] may find a niche for themselves.” Along with IBM Lotus Notes, Chen says Novell GroupWise is also a popular alternative for mid-sized businesses. “There are clear advantages to going with an accepted platform like Exchange, though,” concedes Chen. “In terms of the skills, ecosystem, and add-on products that you can take advantage of, Microsoft applications dominate [small and mid-sized businesses] and mid-market, and Microsoft has been integrating heavily with Exchange and SharePoint.” For some companies, e-mail isn’t a top priority, adds Chen. “Many rely on advanced functionality, applications that might be critical to their business, like unified messaging and shared folders – something Exchange does well.” PostPath and others Levitt says there are many alternatives to Microsoft Exchange. Along with IBM Lotus Domino and Notes and Novell GroupWise, competing integrated collaborative environments (ICE a.k.a. “groupware”) include Oracle Collaboration Suite, Yahoo!’s Zimbra Collaboration Suite, and PostPath, “which looks just like an Exchange server to other Exchange servers and to Outlook clients,” says Levitt. Sina Miri, spokesman for PostPath, which Cisco agreed to acquire on Aug. 27, says their clients prefer PostPath to Microsoft Exchange Server for a few reasons. The most critical is PostPath performs better on all hardware, says Miri. “This is especially true with modest and even low-end hardware, plus it’s low maintenance due to its architecture and the use of the file system as opposed to Exchange and its Jet database,” explains Miri. Standalone e-mail server software competitors include Sun Mail Server, CommuniGate, Ipswitch, MailSite, Gordano, Mirapoint,  Scalix, and the Unix-based Sendmail. Levitt says free hosted consumer-oriented webmail services are often used by individuals for business purposes — such as Yahoo!, Gmail and Windows Live Hotmail — or free mailboxes bundled into Internet connectivity services, such as AOL, Comcast, Earthlink, Research in Motion, Verizon, and so on. Linux, too Linux has grown to be a low-cost alternative to Windows, says Levitt, and so companies like IBM, Novell, and Sun “have embraced the alternative operating system with competitors to Microsoft Exchange, which operate on the Windows platform.” The open-source movement can’t be ignored, says Levitt, especially with relatively high upfront costs for Microsoft Exchange, “not to mention ongoing upgrades, some of which you have to pay for, as well a licensing complexities when you’re dealing with multiple computers.” On the flipside, however, it might be harder for IT people to manager alternative software, which might add to your bottom line. “Many rush to open-source products because there is no initial check to write, but you don’t get anything for free,” cautions Levitt. “There are always associated costs when you’re dealing with a product not as well established or supported as Microsoft Exchange.”
