Server & Desktop Virtualization
There is a lot of talk about “the cloud” and virtualization these days. How can you discern which approach is best for your organization?
Stemp Systems can help. We have decades of experience that we can apply to help you determine the best possible solutions to meet your needs, but first let’s define some key terms:
Virtual Server: Server virtualization is the partitioning of a computer server to act as multiple virtual servers. The resources of the server are hidden from users and software divides the system into multiple virtual environments called virtual or private servers. Possibly the most common usage of this technology is web servers because it provides a low-cost way to provide web hosting services to multiple parties.
Virtual Desktop: Desktop virtualization basically moves your desktop applications and data storage to a centralized server to improve access and lower costs. This requires the virtual desktop to be connected to the server either through a network or the Internet.
The Cloud: Cloud computing is Internet-based computing where shared resources, software, and information are provided to a growing variety of devices including computers on demand. In some ways it is similar to our national electricity grid. Cloud computing is a natural evolution of the widespread adoption of virtualization, service-oriented architecture and utility computing. The term “cloud” is used as a metaphor for the Internet.
The fact is often 90-95% of your computer/laptop’s resources sit idle at any given time and servers utilize as little as 5-10% of their hardware capacity. This means one server can power up to 10 virtual servers providing significant cost savings in addition to the reduced cost of PC ownership when going virtual over your network or through the cloud.
According to IDC some of the significant benefits of virtualization include:
- User density increases dramatically. The average user density grows by a factor of three on a per-server basis, while number of users per server manager goes up by a factor of between four and five times.
- Availability improves. System availability goes up even for basic virtualization. The real benefit comes from an advanced virtualization scenario in which downtime drops by 50%.
- Scalability is a click away. Once virtualized, an application that needs more scalability can be moved to a server that can fulfill that requirement with little more than a few clicks of the mouse.
- Cost reductions occur. Cost reductions occur across the board, but with future deployments, customers can move to server operating systems that offer unlimited virtualization rights, extending their savings dramatically in many cases.
- Automation of routine tasks. Management software can be used to automate routine tasks, such as monitoring common infrastructure alerts and automating responses for known conditions, leading to an increase in IT staff efficiency.
- Leveraging staff resources. Use of management software helps increase the proportion of staff time used for productive work, increasing business value.
- Higher availability. System and network uptime plus application and database availability are key requirements for conducting business today. Downtime has direct costs to the business that come from loss of business opportunity and decreased end-user productivity.
- Faster response to incidents. This can occur in a number of ways, ranging from automated responses to simple alerts and alarms, to automatic creation of trouble and repair tickets for service desk functions, to problem determination and resolution aids such as event correlation, impact analysis, and root cause analysis.
- Cost savings and improved return on investment (ROI). As demonstrated repeatedly by numerous IDC studies, the overall effect of using automated software tools for IT infrastructure management typically results in cost savings and positive ROI. Areas for cost savings include reduced hardware and software costs, IT staff efficiency, end-user productivity, and enhanced operations for business applications, including reduced downtime and faster performance.
Using IDC’s calculations, the average company deploying basic virtualization could see an ROI of 472% and payback in less than a year, including deployment time. This is a very significant ROI for a relatively low-cost, low-risk initiative.
Nevertheless there are pros and cons in every technology. The arguments for and against virtualization can be quite confusing to our clients.

Khalid from Stemp fixed my virus situation yesterday – they are amazing!!! —
You guys are really top notch. I had two "Thank you Stemp Systems" experiences today I want to share with you. —
Stemp is great, I know there is a premium but it is well worth it…I have had several issues over the years and Stemp was able to help me remotely which was immeasurably useful to me. —
I think you guys acted in a very professional and efficient way. GO STEMP GO!!!! —
Kurt is a great asset on your team. Just know that I appreciate his prompt resolution and attention to our issues. —
A special Thank You goes to Khalid for his patience, perserverance and ingenuity in identifying the problem, establishing a solution, and then figuring out how to implement the solution in the face of numerous obstacles. All on a Sunday morning! —
Again, your support team is great. Martin has been working hard to resolve stuff for us. He’s a very nice, intelligent and personable guy. Please pass that along for me. We all need a little pat on the back once in a while. —
You guys did a wonderful job and everything is working great. —
We were originally referred to someone to build our network; the person came, and he didn’t know what he was doing. What was worse was that I didn’t know that he was inept until it was too late. As our EMR go-live date approached, it became apparent that I needed someone else. Stemp Systems came to us on a Thursday worked literally 24 hours, day and night, through the weekend, so that we could go-live on Monday morning. —
Daniel, First of all thanks for keeping me in the loop. I also thank you for your Friday evening phone call. I really appreciate your hard work, and thanks for a job well done. —
Thanks for the super-fast response! —
Dear Stempies, Now that I am calm, I just want to thank all of you for your hard work. I really appreciate your work and efforts. I apologize if I was rude this morning. It is so amazing that you work until midnight and then make it to work with such positive attitude. Thank You Stemp Systems Group. —
I like your team and enjoyed working with all of you. Ben is very conforming and plans well ahead. Aleem is like me, goes ahead and completes the tasks. Dennis sits at one place and works with a deep focus. Dan is very accommodating and pleasant to work with. —
The work done by your technician was very efficient and pleasant.
Thank you for all your great services! —
Neal was excellent. Thanks again. (New office configuration) —
Just a note to let you know that I was extremely happy with the help I received this morning from Joe. I had a pernicious and debilitating computer virus, which generated extraneous file extensions on many of my files and programs, and as a result, I could not run any of my programs or access any of my files. Joe was professional, courteous, quick, and most importantly, extremely competent and effective. By 11:00 I was back up and running cleanly. —
Recently our incumbent local carrier experienced underground cable issues and 5 of our 9 point to point circuits went down. This could have meant disaster for our satellite offices accessing our EMR here at the main location. All of the failover measures Stemp put in place kicked in automatically, our EMR system was accessible, and we could see patients from all satellite locations. Kudos to Stemp Systems for keeping our best interests in mind when designing our network configuration. —
I just wanted to let you know that I’m very impressed with Anthony - how he migrated a workstation from XP to Win7 last week and the user didn’t have any issues. Great job Anthony. Keep it up! —
Dennis, Thanks for the great job you did solving how to access the path containing the content for the dtSearch database, and then re-indexing the files from server 4 to server 1. I appreciate it very much and it works well. —
I just wanted you to know that your people are awesome…they are polite, thorough, accommodating, and very competent. It’s a pleasure to deal with them. Thanks. —
Kurt, I really am enjoying the computer during my travel. I want to thank you for the extra effort in setting me up hours prior to my flight.
I look forward to our near future projects. —
I’m sure my network is far more advanced than most of my colleagues in the New Haven community. One group uses a ‘Nerds on call’ type of company as their IT people. These companies are fine for home repair or small business IT but I wouldn’t trust them with 20,000 confidential patient records. Stemp Systems is always one step ahead. —
ALL FIXED!! THANK YOU SO MUCH!! My day was going down the toilet VERY quickly. Thanks for making it better. —
I want to thank you, Morris, for the way you handled this recent repair incident. It’s good to know we can depend on you and your well qualified staff to keep our (almost) 24/7 operation going. —
Thanks for everything yesterday. Everything went well and Steven did a great job. —
Joe, I just want to thank you once again for taking the time to program those computers that we donated. I dropped them off this weekend and everyone was very thankful and very happy. They will make a big difference at the senior learning center. You are a true hero! With much regards and appreciation. —
I am extremely happy with Peter. Amazing guy. You sent THE best and I appreciate that!!!!! —
Hey my friend - just want to thank you for your great staff - the guys were really good today - they helped me tremendously. Thanks. —
Looks like it could have been some virus scan issues. Kurt made some adjustments to that and other areas of my computer. Kurt is very knowledgeable and great to work with!! Thanks for everyone's help!! —
Morris – all taken care of in your usual efficient and competent way. Thank you for your help. —
I just wanted to tell you that Kurt was fantastic with the auditors, he was professional and so knowledgeable in his answers and his presentation to the senior auditor that was in charge of the IT component. After Kurt left she actually informed me that she was very impressed with Kurt and the information he was able to give... You both should be very proud of how Kurt represents your corporation. —
Stemp has been our IT GURU for the past 10 years who continually guides us through the technical complexities of delivering healthcare services. —
I have to go on record to say that I think you and all your team did a very good job. Yes, including the project management. —
I spoke to Khalid and also worked with him on an issue that is not yet resolved. I find him to be a very good asset to the Stemp Group team. He was very calm and professional. It was a good experience. —
Big shout out to Anthony who has hit the ground running! This was our first out-of-country set up for my team and it went seamlessly! —
I want to congratulate you and your team. From my view this was a very difficult project and Steven and Peter showed the upmost professionalism under difficult circumstances. Without the whole team including, Martin, Dan, Kurt and you, I would never imagine this project being completed.
Thank you. —
I also want to thank Stemp for your tremendous support during the weekend upgrade to the new eCW program. Patty tells me this is the smoothest upgrade our facility has ever accomplished. I think all of the direct interactions between our company, Stemp and eCW did the trick. She was also surprised to see Morris at the company Saturday when our main server failed. Again, thanks for all of your assistance and all of us are looking forward to a continuing relationship. Thanks. —
Conversion done timely, excellent, professionally... Beverly was very good. She gets very high marks in customer satisfaction. Soft spoken. Comforting. Dan is excellent. Bright guy. Sat down, did his job, got it done. No chit chat. High marks to Jerry and Neil. —
Wow, thanks! Between noticing the issue with our website and the speed at which your tech came and helped yesterday I am happy I made the decision I did. —
Aleem, I really appreciate all your hard work on this. You always go above and beyond my expectations. Thank you thank you. —
I wanted to take time today to email you regarding your employee Neil. His customer service and help with various issues today should be commended. Neil was knowledgeable and helpful and conscious of the other projects I had going on in my day. I just wanted it to go noted, as I'm sure complaints are the only thing customers write about. —
Kurt, Nice going getting FIOS to work with SonicWall yesterday! Thanks for figuring a complex task out, and for walking Jason through the installation. —
The products and services Stemp provides are a mission critical piece of what we do. We can work without other supplies. There are work arounds. But when we lose our computer system, it’s a disaster. There are few things we buy that are as critical as that … maybe electricity, telephones. But even without telephones we don’t have to turn patients away. Without computers, we’re flying blind. —
Once again, the awesome one comes through. —
Aleem, I really appreciate all your hard work on this. You always go above and beyond my expectations. Thank you thank you. —
Morris: You don’t have to thank me for a compliment – you’re more than worthy. You continue to amaze me with your expansive knowledge and you never hesitate to step in and use it when called upon. So, many thanks to you and your team. —
Just wanted you to know that your people are awesome...they are polite, thorough, accommodating, and very competent...a pleasure to deal with both of them (Jerry and Steve)...thanks. —
I just wanted to say that the move this past weekend was amazing. The Stemp team could not have been more organized, and the extensive planning and expertise really showed through. I would love to single out each and every person, but it would take too long since there is so much to say. Please pass on our thanks and appreciation for an awesome job well done! —
I want give you feedback that Mike was extremely helpful with the issue I had this morning –Thank you —
Michael and Sophia,
Thank you for a very smooth Aprima (EHR) upgrade. It is always a pleasure and relief that I have " the Stemp crew "
to keep everything computer related running well.
Have a wonderful weekend. —
I had a chance to work with Asad, last night – actually middle of the night. He helped me with number of issues. For middle of the night he was awake & resourceful. He was confident, focused, and quick in executing his ideas in resolving these issues.
I also must say that the quiet of the night must add some measure to the concentration one needs for the task of solving some of these riddles. I congratulate you for keeping your offices open 24/5. —
Just to let you know, Joe really went above and beyond to get my iPhone Contacts cleaned up and functional. Not to go into all the technical details, he called Apple Support multiple times, called me back > 6 times, called me from home and went the extra mile. Kudos to Stemp for a great employee. —
Thank you. It’s reassuring to know that your team can react so quickly to such problems. (Regarding server that shut down during the night.) —
Dr. G gave good feedback regarding Jerry (who helped set up a remote connection from his new iMac). He was helpful and well-spoken. —
As I said 1000%. I will say "only the truth." You guys are amazing. —
