A Key to Selecting the Right Operating System to Host Your Website

Right-Operating-System

Are you confused when presented with which operating system to choose when selecting a web hosting provider’s hosting packages? You’re not alone. And no, it doesn’t matter what operating system you have on your desktop or work station – they don’t have to match your hosting platform. You can be using Windows 7 on your desktop and Linux on your web server. So what are the key guidelines to select one versus the other?

Applications make the difference

On a shared web hosting platform, both operating systems are normally priced the same. If you’re leasing a dedicated server though, Linux is open source (free) and Windows is proprietary to Microsoft applications that require license fees. If you need services like Active Server Pages (ASP), MSSQL, MS Access, Visual Basic or remote desktop, these applications are Windows specific.

Are Linux servers more secure?

I see this brought up quite often in comparisons and the answers are all over the board. Very simply, the answer is NO. Both operating systems can be locked down tight. What I generally see are providers that only offer Linux platforms stating that Linux is preferred.  Both support a wide range of software applications, languages and databases.

Control panels for operating systems

Control panels do vary by operating system platforms with cPanel frequently offered for Linux versus Plesk for Windows. Of the two, cPanel is more popular, but both are comprehensive.

CentOS is popular, but there are other flavors

There are different flavors of each operating system: with Linux; CentOS, Debian, Fedora, Ubuntu and others, and with Windows; 2016 Standard and Data Center Edition.

My recommendation is to match your specific requirements to the Operating System that best fits your website. If in doubt, call us – 800-615-9349. We can help.

IPv6 Subnet Cheat Sheet

IPv6 is a complete and different animal as far as subnetting goes. Please note the yellow rows as
each has special common use or notes. If there is nothing in the “Amount of a /64” column that means
it is to miniscule or to massive to justify calculation. Not much is the same with IPv6 compared to IPv4.
Route aggregation and purpose drive subnetting is something which every enterprise IPv6 deployment will make
use of, or it will fail miserably.

What’s The Difference Between VPS And Dedicated Servers?

When it comes down to VPS vs Dedicated Hosting, theres more to your application than placing a site online.

For an individual, or small to medium sized business, who has either outgrown the rigid confines of a Shared hosting plan, or who knows from the outset they want more power and control over their online presence, two options to consider are Virtual Private Server (VPS) vs Dedicated Server hosting.
