I highly recommend it because it's the most used operating system in the world. If you work with other organizations or share info, it's easier if you have the same system instead of Linux, for example. Also, a large number of employees know how to use it, but not so many know how to use Linux or macOS.
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.
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.
An all-purpose operating system for business or personal users. Overall, the OS is very user-friendly and intuitive, enabling even new users to quickly utilize the system. The same can be said about the apps within Windows. There is also good cross-functionality between applications, although the ease of use could be improved.
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.
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.
We selected Microsoft Windows because of the user friendly nature of it and a big factor is that other user never used macOS or Ubuntu so the productivity will decrease a lot because you have to explain a whole new OS. I always only recommend macOS or Ubuntu if you are a graphic designer of a developer. But for the day to day office work Microsoft Windows is the way to go.
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.
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.
