These days, the average web hosting company has thousands of websites to maintain and even more customers to keep happy.  Manually performing all of the required tasks across multiple web servers is prohibitively costly and in many environments, impossible.  Being that web hosting is such a demanding operation, even seemingly trivial processes such as creating email accounts would be overwhelming difficult.  This is where control panels and automation come into play.  With a quality control panel application, hosting providers can get an efficient handle on server administration while their customers can manage virtually every aspect of their own websites without intervention from the host.

Control panel software is designed to automate various aspects of server administration, taking the pain out of intensive manual labor.  Some of the most notable include creating email accounts, SQL databases, access control and facilitating software installations among other administrative functions.  Most of these programs work by providing each domain and website owner with a unique access ID, which gives them access to the user interface of the control panel.  When the user logs in to their hosting account via the software, they are then able to perform a number of different server administration tasks based on the available features, resources and access permissions.  A good control panel will not only allow you to accomplish server administration with relative ease, but also monitor your resource usage, view server logs and manage your files right on the software.

Commercial vs. Custom Control Panels

When it comes to control panel applications, web hosting firms generally have two options.  They can choose to purchase an out of the box commercial solution, or build their own custom software in-house.  A large number of companies have elected to build their own software programs due to their proprietary hardware infrastructure, assured compatibility and to elude the often expensive licenses that come along with commercial products.  On the other hand, developing custom automation software in-house can prove to be both time consuming and expensive.   Most importantly, it could result in a much steeper learning curve for the hosting provider’s customers.  Therefore, most companies utilizing generic software and hardware components are better suited for out of the box commercial solutions as they typically offer the utmost in convenience for the end customer.  These type of control panels eliminate the cost and complexities of designing the application and also cut down on technical support as customers will be less likely to rely on assistance from the host.

Summary

Control panel software enables web hosting companies to drastically reduce overhead expenses through the simplistic power of automation.   This in turn, allows them to be more competitive in terms of pricing and even extend that power and control onto their customers who can perform a number of server administration tasks regardless of their technical knowledge.  From cPanel and Plesk to DirectAdmin and Helm, control panel software plays a key role in making sure web hosting is simple and affordable.

Control panels are certainly a vital element in today’s web hosting operation, helping to transform complex tasks into simple processes that can be handled by users of varying skill levels.  The vendors that distribute these products and the hosting industry in general have no trouble pushing the software on the market, but critics are now questioning whether control panels are truly necessary in the VPS environment and what value they actually provide.

Potential Issues

In terms of performance and security, industry leading control panels such as cPanel and Plesk are not always what they are cracked up to be.  These powerful applications consume a great deal of resources and often force customers to upgrade their packages to continuously thrive in a VPS hosting environment.  This consumption is due to HTTPD processes ran by web servers like Apache that make a VPS more susceptible to performance issues and less able to handle exploits such as DOS (Denial of Service) attacks.  Though very useful, cPanel and Plesk are both resource hogs that are more likely to reduce the overall responsiveness and performance of web applications, leading customers to upgrade to more costly packages they do not necessarily need.  In addition to this, even simple tasks such as creating email account and managing databases are slow and lagging processes that generally take too long to complete.

Alternative VPS Control Panels

cPanel and Plesk are ideal for shared and dedicated hosting arrangements but could result in more problems then you bargained for when using them with a virtual private server.  Two more efficient control panels you may want to consider for your VPS hosting solution are DirectAdmin and LxAdmin as both are incredibly lightweight and consume notably less system resources than cPanel and Plesk.  This essentially means they are far more responsive, faster and likely to give you a better performance than the leading products.  A number of tests are increasingly showing that they are also more stable and secure than the competition.

Many observers are stepping out to the make the claim that cPanel’s days as a VPS control panel are numbered, attributing this to the fact that is the most resource leeching solution.  Due to its mass popularity and widespread use, it is also among the highly targeted by hackers, which presents numerous potential security risks to your hosting environment and sensitive data.  For this reason, you may want to carefully consider utilizing this control panel with your virtual private server.  Unless you have a robust VPS plan with a lot of RAM or absolutely require automation, it might be worth the risk to install a glamorous commercial product.

Conclusion

We are not telling you to refrain from using cPanel or Plesk as both are on top of the control panel market for obvious reasons.  However, in many situations, going with a lighter product or performing command line administration will allow you to get the job done in a faster, more efficient and secure manner.  Fortunately, there are several control panel applications specifically designed for the VPS environment, better assuring the optimal performance and adequate security you need to thrive with your web presence.

SysCP

The SysCP control panel allows you to manage your web space, mail, CGI scripts, DNS settings, create custom error pages, view statistics and more.  The features integrated into the software provide you with the ability to control a wide variety of applications including Apache, BIND, Courier and ProFTPD.  While there are numerous modules built-in into the control panel, there are even more extensions available for download that enable you to administer other aspects of the server.  Some of the third-party modules for SysCP include tools that allow you to manage applications such as Fetchmail and SpamAssassin, perform backups of your critical data and more.  This control panel supports five major Unix-like distributions with the most notable being Debian, Gentoo, FreeBSD, OpenSuSe and Ubuntu.  Under the GNU GPL, SysCP can be freely distributed and modified.  Before installing SysCP, be sure to check for compatibility as it supports certain versions of the afore mentioned operating systems.

Webmin

The Webmin control panel is becoming an increasingly popular option for dedicated server customers.  This software is incredibly easy to use and loaded with a number of features, which are primarily modules that provide the ability to administer the server.  It comes standard with modules for Apache and BIND, a BSD firewall, bandwidth monitoring, a cron job manager and much more.  Aside from the built-in modules, Webmin  supports a variety of third-party extensions that can be downloaded from the web.  It also gives you the option to develop your modules.  Webmin currently supports more than 80 different operating systems including Unix, FreeBDS and several variations of Linux.   Because it is under the GNU GPL as open-source software, many developers from all over the world have contributed to the code and improved the software.  The most recent versions of Webmin have been released under a license similar to that of BSD, basically meaning that it can be freely distributed and modified for both commercial and non-commercial use.
