Windows Dedicated Server Vs Linux Dedicated Server

Factors To Consider When Choosing Between Windows and Linux Dedicated Server

Here are five key factors that you must consider when choosing between Windows and Linux dedicated servers.

1. Cost
2. Performance
3. Usability
4. Security
5. Compatibility

Let’s look at each one in more detail to give you a better idea.

Cost

One of the foremost considerations for most businesses is the total cost of ownership. At first glance, Linux servers appear to have significant cost advantages: The Linux operating system itself is free to install, whereas Windows server licenses can be expensive and add to the dedicated server cost. Microsoft typically charges per core, so multiply by the number of processors on your server hardware.

Linux servers have the ability to run on a wider range of commodity hardware, right from low-powered single board computers like Raspberry Pi to enterprise-grade rack mount servers. This allows you to fully customize configurations to match your workload and budget. Windows platforms generally have stricter hardware requirements, limiting cost-optimization flexibility.

Administering Windows dedicated servers requires specialized skills and training which translates into higher IT salaries you need to budget for. Linux server admins are more common and hence have lower salary expectations. The learning curve for Linux is also shorter if your team only has desktop Windows experience.

However, while the above factors make Linux platforms seem dramatically cheaper, for organizations without Linux expertise, migrating to and managing Linux environments can be highly complex and expensive. If your IT team lacks experience in Linux, the training time and initial migration costs may outweigh any licensing savings. Downtime, bugs and security vulnerabilities caused by improper Linux configuration and maintenance can become extremely costly.

Make sure to do a thorough cost analysis of the migration process before deciding solely on upfront Linux software savings. On the other hand, if you have seasoned Linux professionals on staff, you can optimize spending by using low-end hardware and custom-tailored operating system deployments. This allows squeezing the most value out of your dedicated servers.

Performance

When it comes to pure performance, Windows and Linux both can be optimized for throughput, concurrency, uptime and resource efficiency. However, Linux has some intrinsic advantages. The lightweight nature of most Linux distributions results in less memory and CPU overhead. This allows cramming more concurrent requests per server.

Linux’s scheduler and process architecture allow it to handle large volumes of network and file input and output with lower latency. Windows typically prioritizes graphical user interface responsiveness over pure throughput. Linux has native support for advanced kernel features like load balancing, process forking, caching, sockets and groups. These have to be added later on Windows.

The modular nature of Linux allows fine tuning the operating system to the hardware and application. Microsoft Windows has a more fixed design. Linux development tools like Nginx, PHP and MySQL give better out-of-box performance for common web operations. However, for workloads involving ASP.NET web development and Microsoft SQL Server databases, Windows optimizes the stack.

Both operating systems now offer excellent reliability through clustering and failover support. Linux generally has better scaling potential for massively parallel workloads. If you have a website that does not attract a lot of traffic, the Hostnoc server performance differences are not noticeable. Focus on picking the operating system that best supports your apps and database platform.

Usability

Ease of use is another critical factor if your organization does not have specialist server management resources. In most cases, Windows Server environments are inherently easier to get started with and maintain on an ongoing basis. Here are some of the advantages of Windows in terms of usability.

Windows provides a familiar and intuitive graphical desktop interface even for the server operating system. Admins who use Windows on their workstations will find it easy to get productive quickly on Windows servers as well. Routine management and troubleshooting can mostly be done via convenient graphical tools and wizards designed specifically for common server tasks like configuring Active Directory, DNS, firewall policies, Hyper-V virtualization and more.

Windows Server seamlessly integrates with common Windows administrative tools like PowerShell and Remote Desktop. Linux requires more heavy lifting with command line scripting and remote shell access. For user management, Windows Domain-based Active Directory is extremely robust and easy to configure compared to Linux user accounts spread across different configuration files.

For medium and large businesses with dedicated Windows IT personnel, sticking with Windows Server allows leveraging the same familiar skill sets. On the other hand, getting up to speed on Linux administration requires deep diving into understanding distributions like Red Hat, Ubuntu, Debian and SUSE and learning shell commands, text editors and SSH management. For understaffed IT teams, the learning curve can be steep.

However, seasoned Linux admins often prefer command line interfaces and text-based configuration once they get proficient. The ability to quickly edit, copy and execute Linux commands across thousands of Linux servers is powerful but does require rigorous training.

Security

Dedicated server security is paramount for any server deployment, so understanding the key differences in Windows vs Linux security models is important:

Due to the widespread scrutiny of its open source codebase, Linux has generally demonstrated fewer vulnerabilities than closed source Windows platforms. There are simply more eyeballs across the community inspecting Linux for bugs and security holes on an ongoing basis.

Linux allows very granular control of user and process privileges through security modules like SELinux and AppArmor. Running each application and system process with its own limited privileges contains potential damage from compromised services. Windows historically requires fuller admin-level access.

Default user accounts are more isolated in Linux. Services don’t have to run as the root superuser, whereas Windows often requires admin rights for routine tasks and applications.This again limits damage if an account is compromised. Linux’s operating system architecture uses clever process forking, caching and networking features that make DDoS attacks harder to succeed. Windows performance optimizations sometimes override strong security.

Windows Server security has come a long way with features like Windows Defender Firewall and Advanced Threat Protection. The widespread deployment of Windows also results in quick fixes for discovered vulnerabilities. Some organizations may find compliance regulations like FISMA and PCI DSS easier to adhere to on Windows. Both operating systems are reasonably matched on the security front for most practical purposes. Extra hardening and server monitoring may be necessary regardless of your operating system choice.

Compatibility

When evaluating dedicated server options, application compatibility is a major factor for most organizations. Windows enjoys broader application support in the enterprise world. Most third-party applications like payroll systems, ERP, CRM and customized software typically only support Windows installation with no Linux versions.

Switching to an unfamiliar Linux environment may require revamping your application portfolio – a costly endeavor requiring completely rearchitecting your stack. For niche corporate needs outside of software development and engineering, finding compatible Linux applications can be challenging. Support options are also limited.

If you have invested heavily in Windows-based business applications, migrating existing workflows to Linux can be invasive. Sticking with a Windows server environment may be the safer option. However, Linux excels at automation, customization and integration using tools like Ansible, Puppet, and PowerShell Core. For workloads involving extensive coding and scripting, Linux provides way more flexibility.

Also consider that many modern applications are getting deployed on cloud platforms, containers, and orchestrators like Kubernetes where the underlying operating system matters less. This makes Linux a bit more future-proof as newer apps get built on those technologies first before Windows.

Which One Should You Choose?

Here are some closing guidelines on choosing the right dedicated server operating system.

Choose Windows

• If your IT team and admins are already Windows experts, stick with Windows Server for fastest productivity.

• If your application portfolio centers around Microsoft technologies like ASP.NET, SQL Server, Exchange and Active Directory, Windows servers integrate better.

• If partner and vendor support coverage is important, Windows may be a safer choice initially.

Choose Linux:

• For heavy network and database driven workloads, Linux provides more optimization capabilities.

• If you are building custom applications with modern DevOps tools, Linux aligns better.

• For tight cost constraints, Linux unlocks more potential for frugal hardware and open source stacks.

To leverage the unique strengths of both platforms, a hybrid on-premise environment with Windows and Linux servers is ideal for advanced needs.

Conclusion

The best server operating system depends on your in-house skills, applications, IT budget and workload patterns. Performing detailed requirements analysis and proof-of-concept testing is advised before committing fully to one platform. With careful planning, you can maximize the benefits of Windows and Linux dedicated servers.
