CentOS Linux vs. VMware Workstation Player vs. Windows Server

In any role where you need raw server power, CentOS Linux is extremely well suited. It is extremely stable, and in my experience, probably the most stable of the Linux distros available. It has a very wide base of support from 3rd party sources for additional functionality that do not come already in the CentOS Linux distribution itself. It is not as appropriate for situations that are customer facing or end user facing. For those, I recommend Ubuntu Linux. But for everything server & compute related, I recommend CentOS Linux.

VMware will work great for the following test scenarios:

• Testing windows updates on a system
• Testing a new software or a new software version
• Creating a sandbox to test options/features of an OS
• Creating different VM to test a software on different OS without the need to have physical machines for all of them

You can also use it as a "player" only where you have that static VM that you run from time to time as with my use for SAS University. Whenever you need to use the software, you simply start that VM.

Windows Server and Active Directory is very robust and stable, it has been a staple in every IT environment I have worked in during my career. Junior to Intermediate admins can learn Windows Server easily, the user interfaces make administration tasks very easy as well as the documentation available through a vast amount of resources. There are other Operating Systems available with no GUI which has a smaller attack surface, faster update installation and reboot time. Windows Server does have the ability to remove the desktop experience, however it is not something I have had experience with and I believe most administrators choose not to remove it.

• First of all, CentOS is one of the most secure and stable OSes straits from the box.
• High performance on the average hardware.
• In most of my scenarios—easy and quick deployment.
• Huge KB community that helps to build and support different services on CentOS.
• Versions lifecycle.

• VMware Player is easy to use.
• VMware Player supports a wide variety operating systems.
• Unity mode makes it easy for the end user to utilize needed legacy applications while maintaining their familiar Host OS desktop. It's seamless to the point where the end user doesn't know they're running applications from a VM.

• Backup of workstations & itself - reliably, consistently, with Bare-Metal Restore and deduplication
• File management and Security on a per file/folder/user basis is simple and fully done through an easy GUI
• DNS, DHCP server functions are easy to configure using the built-in GUI

• CentOS is not a great desktop platform. Although some would disagree with that statement, I think that CentOS is better suited to life as a server.
• Since CentOS is community-supported some software vendors will not officially support it because it isn't Red Hat.

• Would be nice to use more VMs at once, but this is basically trial software, so it's hard to fault them.

• Microsoft needs to minimize the update frequency by making the product more secure. It can become very exhausting trying to keep updated if you don't have a dedicated support team. It can become challenging where the business is unable to allow downtime for reboots as part of the update process.
• Prone to security and audit vulnerabilities.
• The operating system needs more CPU and memory resources compared to other options such as Linux.
• Understanding the licensing model can be abit confusing.
• Comes with a standard firewall, but not the most secured one available. Would suggest using a more secured firewall as part of your antivirus software.
• Due to the number of vulnerabilities and the operating system being a target for hackers, anti-virus software is a must.

I give a rating of 8 because VMware Player has its use cases, for example it requires the host OS to be logged in, and the VMware Player application to be opened and the Guest VM started. Only one VM can run at a time. I'd give a 9/10 to VMware Workstation because you can run shared VMs at startup without logging in or starting the workstation application. and i'd give ESX a 10/10 because ESX is the leader in enterprise visualization.

I've carefully reviewed the servers and services currently running on Windows Server 2012, and given the opportunity would renew them as is going forward. There are two systems I currently have in place, one is a very large Linux implementation for a large ecommerce site, and one is a very large backup solution front ended by FTP servers running Linux. Neither are well suited for Windows, but the overall network infrastructure is and will be Windows Server for the foreseeable future.

It is a very typical server software, so you will have just the console. But it is still very easy to use, you can do anything from there and you have te built in manuals to review any information. For the other hand, if you need a graphical environment is not an issue, you can install any environment you what, Gnome, xfce, etc.

Great product. Its user-friendly GUI and overall performance are really the biggest strength of this tool. The reason why I don't give a higher note is because of the price. Although it's decent (starting at around $200 for a license), there is a good free alternative in VirtualBox. Not everyone values friendly GUI as something worth paying for. For people that are more tech-savvy, I would recommend looking into VirtualBox as they might actually like the model better (with downloadable add-ons and packages).

Anyone new to IT could easily use the familiar Desktop Experience (GUI) version because we all know how to use Windows, whether a client or server version. Once an IT user is more comfortable with the operating system, they can move on to the Core version, which is the way to go in almost all situations.

some times server hungs and user sessions were busy to connect

Integration isn't really relevant here but I see this question more as an OS compatibility for the VM. They state that they support over 200 different OS versions. I honestly have never tried anything else other than Ubuntu and Windows myself but nonetheless, this is impressive. I have not hit any limitation in my use of this software in terms of limitation or conflicts with other software.

need to improve the performance more

Again, written documentation is excellent, even on the older versions. The support community is the best. It is comprehensive and I would say that it global because it transcends national boundaries. Also, you find all types of people using CentOS to do all sorts of things so you are bound to find someone to talk to if there are problems.

VMware support is very knowledgeable on their products, eveything from AirWatch to ESX clusters. VMware is easy to contact, they stay in touch and see the issue through to the end and a final resolution. They keep you up to date on your issue status and don't leave you waiting for answers.

Microsoft's support is hugely wide-ranging from articles online to having to contact them directly for the more serious issues. In recent years when I have contacted them directly, I have found the support o be excellent as I have found myself connected to very knowledgeable people in the field in which I needed the support. The online support available is vast and I tend to find most of the time that there is always someone out there who has had the same issue as me in the past and knows something about how to resolve it! This is the advantage of using industry standard and long-established systems such as Windows Server.

it was my senior who trained Windows Server features and i was satisfied

it was recorded session and useful

Installing the application was easily completed on the twenty computers that needed VMware Player. Once those 20 users were configured we copied our virtual machine template to the 20 users and turned on their newly provisioned virtual machines. We then configured unity mode so the user could easily work from within the virtual machine from their host desktop.

Make sure that you have detailed processes in place for every server instance you plan to install/upgrade, if possible get the base OS loaded and Windows Updates applied ahead of time, and if using a VM take a snapshot prior to installing each role, as well as along the way.

CentOS is based on RHEL, so it really came down to the costs when making the selection between our options. RHEL offered more support and features, but nothing that we specifically needed. CentOS is fully customizable, something Windows Server was also lacking in many ways. The stability and speed was unmatched in comparison to Windows, and we were not utilizing any Windows-specific software to require us to use the Microsoft alternative. My years of experience have also made it a breeze to set up and configure new CentOS instances, leading me to stay where I'm comfortable.

Both free, VMware supports USB 3.0 while VirtualBox does not. VMware supports nested hardware-assisted virtualization while VirtualBox does not.

They are different experiences, and while the other solutions offer enterprise-grade stability and, in some cases, address Windows server shortcomings (such as patching), they all do the trick, but the other solutions require a deeper technical background/configuration of items at the command line, which some people are not fully comfortable with.

need to reduce a lot

yes i completely agree multi deployment

i like the professional service but need to improve

• CentOS's support of RPM packages makes it very easy to replicate RHEL servers for development or testing in cheap / free environments
• CentOS's minimalistic desktop environment requires additional tweaking / packages if you want to have a usable desktop environment with the niceties of other modern distributions. As a result, if developers want to use CentOS, they'll need to spend more time customizing it than other distros.
• CentOS's easy customization from the command line lends itself well to our virtualization infrastructure where setup can be easily scripted to modify CentOS's configuration files.

• A positive impact is that it require little to no funding to use.
• Negative impact is that because it is free it can be hard to get support.

• Ability to keep all files in one place and give access to users makes file management easy to control.
• VPN Access to off-site users is a plus.
• Secure access to on-site SQL data from our accounting and estimating data is a plus.
