Dedicated hosting requires the clients to choose the operating systems for their servers. To get it right, the admin must first understand the business needs and then explore the available options. This includes:

Familiarity with the operating system. Ideally, it is better to choose what the client is familiar with.

Reliability, reputation, stability, and security of the OS. It is also good to look at how the developers update the OS to fix performance and security issues.

Compatibility with existing and future operations and applications.

Customizing options: Some operating systems - especially open source - are customizable, hence allowing customers to personalize their platforms to meet specific needs.

Technical support: Most OS developers have in-house technical support professionals to assist clients and fix issues. The open source operating systems may not have reliable support, but clients can get this in the premium versions.

Resource requirements in terms of RAM, processing power and storage.

Price of the OS: The cost of the operating system differs depending on the developer, version, features, support and other factors.

Limitations such as maximum RAM, disk partition, and applications it supports.
