Physical Vs Virtual server : Which one should you choose?

Gone are the days where people thought of “servers” as big, bulky machines installed in data centers. Now, “servers” more often mean cloud instances or VPSs.

All that being said, dedicated servers are still a favorite choice for many. Research shows that dedicated server market grows by $237 million each year [1]. So, the question is, what’s the better choice between virtual and physical servers?

Physical vs Virtual servers

Dedicated Server Hosting is still alive and thriving


As a company that provides Server Management Services, we are often asked what’s better – Virtual or Physical servers. We help digital marketers, web/app developers and other online businesses maintain their server infrastructure – and over time, we’ve learned that there’s no one-size-fit-all solution for all businesses.

See how our server support staff helps you!

There are several factors such as Security, Performance, High availability, and more, that determines which server infrastructure is ideal for a given business. Today, we’ll go through the top 7 factors, that we found as important.

1. Performance – Physical servers have the edge

Let’s get one thing clear first. If you take two dedicated servers of identical capabilities, virtualize one of them, and run the same application in both servers, the dedicated server will always show better performance. Why? Because virtualization always inflicts a performance penalty.

That being said, the difference in performance is noticeable only in applications that run thousands of transactions per minute (like busy eCommerce sites for example).

So, if performance improvement is your sole concern for a server upgrade, go ahead and choose a physical server.

But, before you make that move, know this – Most servers run at a snail’s pace because they’re not optimized. We’ve helped many customers avoid needless investment by tweaking their services, and implementing efficient resource usage.

How Bobcares helps avoid performance bottlenecks

We have a simple principle to keep a server super fast – Catch performance bottlenecks early and Nip it at the bud.

For this, we do 2 things:

  • Detect performance anomalies within minutes
  • Implement a permanent fix then and there
Quickly detect performance issues

For this, our experts keep a close eye on customer servers 24/7, and as soon as we detect an anomaly in performance metrics (such as server load), we login to the server, kill abusive processes, and prevent a server crash.

[ Making your servers stable and secure doesn’t have to be hard, or costly. Our Server Management specialists are here to keep your servers rock solid. ]

Permanently fix performance bottlenecks

We then go one step ahead and trace the source of the high load. It could be anything, like an un-optimized query, a fragmented database table, or an abusive connection. Once the source is identified, we optimize & harden the services then and there, so that a similar load spike won’t happen again.

By making these small incremental, and timely tweaks, we keep customer servers running very fast all the time, and more importantly, prevent a complete server failure later on, that could cost hundreds of dollars to fix, and more than that in lost sales.

2. Cost savings – It’s a volume game

The most popular reason to virtualize is to save money, and it holds true for a vast majority of cases – but there are exceptions.

Virtualization is beneficial only if you have a large number of servers, or if you’re using an open source virtualization solution such as oVirt. The software licensing costs can be too heavy for smaller installations.

Let’s explore this point with a 5 server infrastructure, as shown here.

Now, let’s see what the cost would be to implement this infrastructure using dedicated servers, public cloud and a server virtualization software.

  1. Thank you Sajan, Great explanation.

  2. Excellent post!! in order to understand the advantages between virtualized and physical environment.

    • Thank you Edwin. 🙂

  3. Hello Admin,

    I wanna start own web hosting company like Godaddy, bluehost and Hostgetor, suggest which kind of physical or Virtual Server I need to have and what server configuration should have? which company is best for server installation like Dell, HP, IBM, Sun, and Oracle? plz also suggest me how much server space should have in the beginning?

    • Thanks for visiting our site Bhoopendra. The choice of server and technology depends a lot on how you plan to build your business. How about we talk this over mail?

      • Hi Blessen,

        thanks to reply me, you can reach me through my email bhoopendragauta(at)gmail . com .

  4. In the comparation used by you 5 physical servers are compared with one server that will hold 5 virtual servers? In this case, when you said about the hardware failure “Despite the best precautions, catastrophic server failures do happen due to electrical issues, hardware failures, fire, etc. In dedicated servers, disaster recovery in such instances involve a long-winded process of setting up new servers..” what will happen if this failure will occur to the physical server that is hosting the virtual machines?

  5. Please add a section on software licensing. dB licensing costs play a critical role especially when considering server consolidation.
