SUSE Linux Enterprise Server vs. Windows Server

SLES is a good fit for running supported enterprise applications like SAP, HANA, oracle,.. We use it to run all our SAP workloads, and so far everything has worked great. All libraries are right in the repository, all documentation is correct and the support answers really fast in case you have problems.

Anytime I need a server for something, whether to test a new platform or app, devote a server to hosting something, etc., Windows Server is my go-to choice. Recently I needed a new server to host a web server and web application, so I spun up a Windows Server 2025 VM and was up and running in no time at all.

• Seems Custom made for SAP workloads
• Longest standing collaboration between platform and apps
• SuSE for SAP works seamless on-prem, on SAP Cloud, Azure, AWS & GCP
• Support for oldest SP of SuSE so our customers can run their business without fear

• 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

• The support window for service packs after a new SP is released is too short.
• Community engagement is low.
• There are times when supported packages fall too far behind and create compatibility issues with applications. The Open Build Service usually provides a way around this, though.

• 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'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.

For the breadth of services, features and overall performance, I believe Suse Linux is a great choice for any enterprise. It still has to grow a bit in areas like online help forums and documents, but we are pretty much satisfied with our choice.

There are simply too many different parts of Windows Server to make it a cohesive piece of software. While some of the newer features found in Windows Server 2012 and 2016 have nice UIs that are logically laid out, there are enough parts of the system that is still based on old code with clunky UIs and confusing options to make Windows Server a particularly user-friendly experience.

some times server hungs and user sessions were busy to connect

need to improve the performance more

It's great for basic support issues. But it's less suited for anything that is either obscure or uncommon, and it is very hard to escalate, unless you've built a relationship with your vendor/salesperson.

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

Third party training was fast but mostly unnecessary as we were already Unix trained and Linux familiar

it was recorded session and useful

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.

SUSE Linux Enterprise Server works well with the SUSE Manager, it really simplifies everything. We also do have SUSE 4 SAP, and the SUSE Manager is able to manage them all, even other (up to date) Linux distributions. Patching has never been that easy and the SALT integration is also working without any problems.

I find Microsoft Windows Server is a much easier OS to deploy and administer. It does require more resources to run, requires more security updates and overall has a larger footprint. Rebooting the Windows Server takes a much longer time than RHEL for example. An administration task such as expanding a drive in Windows can be very simple, however in RHEL it is not.

We have successfully deployed on physical servers, VMs and in cloud all over the globe from templates of our own design

yes i completely agree multi deployment

• It allows a very small team to manage a large number of servers, due to its automation and manageability.
• SAP supports it very well, making it straightforward to manage. There are also "recipes" for Oracle which has all of the requisites to install an Oracle DB; which helps with deployment immensely.
• It lets us run large SAP instances in SLES on Power, helping us with support, manageability, and performance.
• Support costs are high, but required for SLES for SAP.

• Support for a wide range of applications (compatibility) This is especially valuable.
• The cost of licensing is significantly higher than that of many competing solutions, which means the justification has to be more complete.
• The initial environment setup with full organization management provides a complete solution set to get started.
• Patching/Frequent updates disruptive nature must be accepted.
