Why choose Windows Hosting for your project?

  • Architecture optimized for C# and .NET

    Process compiled C# and .NET code with minimal overhead. Get ultra-responsive server performance when running your application's business logic.

  • Support for Legacy Applications

    Keep corporate applications running in classic ASP versions or components (.dll) operational, avoiding costly rewrites of legacy but vital software.

  • Process Isolation and Independent Memory

    Windows Server allocates independent memory spaces through Application Pools. If one website has an error or traffic spike, it doesn't affect other hosted applications.

  • Natural Integration with Microsoft

    Connect your applications directly to SQL Server and Microsoft's corporate management tools, facilitating synchronization of your company's data.

  • Granular File Security Control (NTFS)

    Configure detailed read and write permissions at the folder and file level (ACLs). Protect your application's sensitive directories from unauthorized access.

  • Zero Learning Curve for Your Team

    Administrators familiar with Microsoft environments will work in a familiar environment from day one, reducing management time and operational costs.

Impeccable Customer Service and resolution of doubts. Whenever you need them, there is an expert available to assist you and solve the issue. In my case, the few times I have contacted them, they have always solved and applied the desired changes. It is also important to mention that they only call you very occasionally and always to offer you some free service. I have been with them since 2022 and have no plans to leave.

Frequently Asked Questions about Windows Hosting

If you need additional information, there are hundreds of answers for you in our support center.

What is Windows Hosting and how does it differ from Linux Hosting?

Windows Hosting is hosting based on Windows Server. Its key difference is native support for Microsoft technologies like ASP, ASP.NET and SQL Server (MSSQL) databases. Your personal operating system (Windows, Mac or Linux) doesn't affect its management.

What Does Arsys Windows Hosting Include?

Our Windows hosting plans include SSD disk storage (from 50 GB to unlimited space), guaranteed RAM memory (up to 7.5 GB), free SSL Certificate, MSSQL 100 MB and MySQL databases, professional 10 GB email with 5 GB free backup, unlimited subdomains and 24/7 technical support.

Do I Need to Have Windows Installed on My Computer to Use This Hosting?

No. The web server operates completely independently from your computer. You can manage your Windows Hosting from any web browser (Chrome, Safari, Edge, Firefox) and from any operating system (Windows, macOS, Linux, iOS or Android) through our intuitive control panel.

Can I Run Projects Developed in .NET Core or ASP.NET?

Yes. Our platform has native support for ASP and ASP.NET, allowing you to deploy web applications, REST services and APIs developed under Microsoft's environment with maximum compatibility and SSD disk performance.

What Database Can I Use in My Windows Hosting Plan?

You can use Microsoft SQL Server (MSSQL) 100 MB databases natively. Additionally, our Windows plans also support 1 GB MySQL databases (10 in the Advanced plan and unlimited in the Unlimited plan), allowing you to manage hybrid data architectures.

Is It Possible to Install WordPress or Other PHP CMS on Windows Hosting?

Yes. Although WordPress is typically associated with Linux, our Windows Hosting includes optimized support for PHP (with a memory limit of up to 600 MB) and MySQL. This allows you to run WordPress or other content managers seamlessly on a Windows server.

Is the SSL Certificate Included in the Price of Windows Hosting?

Yes. All our Windows Hosting plans include an SSL Certificate at no additional cost. This way, your websites and applications will run under the secure HTTPS protocol from day one, protecting your users' data and improving your SEO ranking.

Can I Host Multiple Domains or Projects in One Account?

Yes. Both plans allow you to create unlimited subdomains and have up to 100 FTP/SFTP accesses. If you need to host additional independent domains in the same account, the Unlimited Hosting plan allows you to add extra websites for just €2/month.

What If My Project Needs More Resources in the Future?

Our infrastructure is fully scalable. If your traffic increases or your application needs more power, you can upgrade from the Advanced plan to the Unlimited plan (increasing your RAM memory to 7.5 GB and your space to Unlimited SSD) quickly and transparently, without service interruptions.

How Can I Ensure My Sites and Applications Are Always Active and Secure?

We offer SSD storage, process isolation through Application Pools, HTTP/2 protocol, DDoS attack mitigation, data backups and a team of engineers with 24/7 technical support to resolve any incident instantly.
