How to Decide Between a Shared and Dedicated Hosting
One of the most important decisions you have to make if you want to expand your business into the World Wide Web is choosing the right web hosting for your Web site.
This doesn’t just involve picking the right company, though. You’ll also have to be able to decide whether you’ll get a shared hosting or dedicated hosting.
A Quick Introduction
Before we talk about the pros and cons of each of these, let me define web hosting first. You cannot go on the Internet without paying for the services of a web hosting firm. These people are like landlords. They own servers, which they lease out to clients, or tenants, who are willing to pay for the available space on the servers.
Now, moving on with this analogy, we can describe shared hosting and dedicated hosting like renting an apartment and owning a house.
A shared hosting is like…
Choosing a shared hosting is just like renting an apartment and sharing it with other people. You share the same basic resources—space, electricity, water, appliances, etc. This translates to sharing the same bandwidth, processor, web space, memory, and the like. Some people call shared hosting virtual hosting. I’m gonna use these two terms here interchangeably.
A dedicated hosting is like…
With dedicated hosting, you have your own web server to yourself. It’s just like owning your own house and enjoying your own resources without other people squeezing in to get some of their own. And just like owning a house, its way more expensive than virtual hosting.
The Imperfect Beauty of Sharing
While on the surface, getting a dedicated hosting is better than sharing a server, there is a single, very compelling advantage of virtual hosting—the price. These days, you can
But that’s another story. Today, we’re talking about shared and dedicated hosting.
Beside this extremely low price, though, are some glitches that usually go with shared servers. I’ll give you a quick once-over.
Possibility of getting banned from the search engines If you’re sharing a web server with several other Web sites, it means you’re also sharing the same IP address. At least, that’s what usually happens. If you happened to share the same address with a spam site and the search engines find out about this particular spam site and ban it, you’re doomed because they’re gonna ban you too. Yep, even if you’re not the spam site. There are some companies, though, that have different IP addresses for different sites on the same servers, so try getting that one if you want to have virtual hosting.
Slower server response If you share the same apartment with different people and you only have one bathroom, then it’s most likely that most mornings you have to line up outside the bathroom before you can use it. That’s what happens with a shared hosting. You need to wait in line before your request is served. So, for example, if someone is looking at your site and they want to view your products, but it takes your Web site forever to load because the server is busy serving up the requests on other Web site, that person might just get fed up and leave your site.
Compromised security Even if you’re behaving well and not tinkering with the sensitive components of the system, if you’re neighbor starts roughing it up, everyone is affected, including you. Especially you. This leads to errors and server crashes and, generally, pandemonium on the system.
The Advantages of Stay-On-Your-Own
You must have figured out by now the pros of having your own dedicated server, but we’ll talk them over nonetheless.
Better Performance This one’s a piece of cake to work out. Since there’s no one else needing to be served, you have all the resources to yourself. It’s like being able to go to the bathroom whenever you need to, without waiting for others in line to finish up. Users browsing your Web site have a more pleasant experience because they have to wait less for pages and images to load.
Better Security Common sense has it that a dedicated hosting poses lesser risks for system crashes. If that happens, you have no one else to blame but yourself.
Unlimited Bandwidth Let’s face it folks. Paying more means you get more. If you pay a lot to get your own hosting, then you must have a lot to put up on your own Web site. So that means companies will provide you with practically endless bandwidth to put up your pages, images, videos, forums, blogs, etc.
More Customization You can choose and install whatever software or hardware you want to use on your server. That means you can design your Web site any way you want and provide the most unique experience for your viewers. That means a lot when you’re marketing a business and want your product to stay on top of you customer’s minds.
Wrapping Things Up
Weighing the pros and cons of shared hosting and dedicated hosting isn’t enough, though. It seems like dedicated hosting sounds far better than shared hosting, but most companies have solutions that address the problems of shared hosting. If this is your first time to get your own Web site — I assume it is because what are you reading this for if you’ve already had experience with web hosting companies? — then you might want to try out a shared hosting first*. See if you can build up traffic first and if you will want to expand your site’s features for better viewer experience. Then you can get your own dedicated server.

Choosing Between Cloud and VPS Hosting
We have published a much better guide on VPS hosting recently. Topics like how VPS hosting works, when is the right time to switch, how to choose, and the right price to pay were discussed in detail. To learn more, read:
The Basics Between VPS and Cloud Hosting
Determining whether
Scalability and Flexibility
VPS servers offer quick scaling to take advantage of additional resources, provided the hosted machine has the resources available. If the resources exist, the VPS server has the ability to upgrade memory, disk space and processor speed instantly. If the requested resources are not available, the entire website must move to a new computer. This could result in server downtime of several hours while the transfer completes. While both types of servers allow you to control the applications installed, a VPS gives you additional flexibility to control each aspect of memory, processor usage and how your disk space is used.
Cloud servers provide the functionality to quickly scale to a virtually unlimited degree. If the server needs additional resources, there is no downtime. The server can be instantly upgraded to access additional bandwidth, memory and processor speed as necessary. Cloud hosting companies charge based on the amount of time the server stays online. For companies that need a high level of service during specific periods of time, a cloud server can significantly reduce costs. Companies that provide courses, IT professionals that need servers for testing purposes, and organizations that need to quickly disable servers on a moments notice find cloud servers adequately fit their needs.
Security, Optimization and Control
VPS servers are similar to dedicated servers since the user can completely control all the resources of the server. Cloud services may store data across any number of redundant servers. It also isn’t possible to know where any single piece of data will be stored at any given time. This means that security is largely out of the control of the user. VPS servers allow the configuration of firewalls, antivirus programs and data is centralized within a specific partition of a hard drive. This provides greater control over the information available on the server. If you want complete control of your server, then a VPS provides the better option. Although, you still won’t be able to configure any settings that are shared among all users on the machine. Only a dedicated server provides complete, unhampered control of system resources. However, if security and control are not the primary concerns, then a cloud server provides a highly scalable solution that appeals to companies with quickly changing needs.
Data Protection
Most cloud services utilize 5 or more disks to store your information. VPS servers only store information on two hard disks. If both disks go down on a VPS server, then your information will be lost unless you have a backup. The chances of 5 or more disks going down is virtually impossible. If you don’t make regular backups, choosing a cloud server decreases the likelihood of a total data disaster. The advantage to a VPS server is that you can more easily configure backup programs in the form of a chron job to make routine backups without worrying about using extra system resources. Cloud servers on the other hand provide as much space as necessary, making it possible to store several versions of backups on the host server without having to worry about running out of space.
High Availability
Redundancy refers to a process that saves information across more than one disk. With a cloud server, there is full redundancy, so if one disk goes down the information almost instantaneously goes to a new server. The new host server restarts immediately, effectively eliminating the time that a website might be down. With a VPS, if the host server goes down, then all VPS accounts on the same server also goes down. Even if you have a backup, it can take several hours for the hosting service to get your accounts back online. For websites that need to be available without fail, the safest option is a cloud server. However, if your website can stand to be down for a few hours every couple of years, then a VPS might provide the better option if you need more control of your server.
Performance
While VPS servers slice up a machine to ensure that each user gets the resources they paid for, the performance of a VPS server may be affected during times of high use by other users on the same machine. Hard drives can only access information so fast, so if every partitioned account serves data at the same time, the server may serve pages and run applications more slowly. The possibility of a time out is also increased when using a VPS server. Since cloud servers don’t store data in a single physical machine, the possibility for slow response times are greatly reduced since the cloud server has the potential to scale immediately during times of peak use.
VPS servers restrict your total resources to what you pay for. However, many machines are overstocked causing the actual resources given to a user to be somewhat constrained. With a cloud server, you actually get what you pay for with the benefit of being able to increase usage as needed. If your server requires more CPU cycles and there are some available, the server can burst to allow full utilization of the resources. Cloud servers are never oversold. The very nature of a cloud server provides virtually unlimited resources to provide you with the best web hosting service possible. Even dedicated servers don’t provide the same level of resources that a cloud server does. For businesses and individuals that need large amounts of resources, or have unpredictable traffic and usage spikes, a cloud server provides the best option.

While cloud servers are secure, a VPS has the capability of completing shutting down specific types of connections through a firewall.

If your website consistently serves pages quickly and never comes close to overcoming the system resources, a VPS may be right for you. If your server continually exceeds the system resources, experiences time outs or has other performance issues, a cloud server might provide the better option.

Choosing a Hosting Plan: The Differences Between Unix and Windows Server Options
Most prospective web hosting customers are familiar with the technology “wars” which have ensued over the past few decades. First, there was the
In the background, however, a smaller-scale war has been raging for almost the entire length of the web hosting industry’s existence. This is the war between hosting products based on the closed Microsoft Windows Server system and those based on open-source
There are several key differences between Windows and Unix web hosting plans, and those differences directly correlate with who should use each technology — and why. Knowing these differences will make the web hosting shopping process considerably easier, and it will reveal a key truth: There is no war between web hosting technologies, as they’re simply not in competition with each other most of the time.
Windows Hosting: Business Customers Have Special Considerations When Shopping For Hosting
There’s no secret about the fact that almost every business in the world uses some form of Microsoft operating environment. Whether it’s the company’s mainstream consumer Windows operating system, or the more advanced Windows Server systems, it’s hard to escape the reach of Microsoft among corporate and enterprise clients. For these people, there is a natural way to
When an enterprise client is looking for hosting, they’re searching for a product which can seamlessly integrate with their existing setup. The key to this process is to save time and money by investing in something which is essentially “plug and play.” Once the hosting plan is purchased and data is transferred, a few easy settings should be able to be configured and the product will be available to entire base of employees within any one company or enterprise setup. That solution is Microsoft.
First and foremost, the company offers the number one database product among major enterprise customers in the form of
In addition to Windows servers’ support of Microsoft’s popular database protocols, these servers also support deep integration with the Microsoft desktop in the form of a remote file server. Most enterprises, before they switched to a Windows web hosting server, simply had their own in-house computer which remotely hosted files for their employees. Moving these files to the cloud is now imperative, as it allows universal access on mobile devices, home computers, and corporate machines.
Microsoft allows these servers to be setup by simply plugging in a few settings via the standard Windows control panel interface. The server is then able to be seen as a native component of the operating system by every Windows computer on the company’s network. That process would take far longer to configure and deploy when choosing an open source alternative.
The most popular method of communicating among major business and enterprises is a combination of the Microsoft Exchange email server software and Microsoft SharePoint collaboration technologies. As these two technologies have evolved, they’ve made it possible for on-the-go communication that syncs between remote and mobile denies as well as company computers and servers.
There are certainly open source alternatives to these technologies, but they’re far less-developed and they take a great deal of time to integrate into the traditional Microsoft environment. Because almost every office uses Microsoft Outlook for its email services, it simply makes sense to choose a Windows host that can immediately plug into that software. On top of it, the web-based interface for these applications closely mirrors the desktop counterpart. That means there’s a very little, if any, learning curve when choosing a Windows server for an enterprise environment.
Simply put, a Windows server is best-suited for business and enterprise customers who are committed to the Microsoft “ecosystem.” That system involves the Microsoft Office suite of applications, easy configuration and integration with Windows, the world’s most popular desktop operating system, and easy deployment and syncing to mobile devices and home computers using technologies like Exchange and SharePoint. While these servers can also be used by individual web hosting clients and those who just prefer Microsoft technologies, it’s highly unlikely that they’d be any better served by a Windows server than one based on Unix. In fact, the Unix method of hosting may be better for their very different needs and requirements.
Unix/Linux Hosting: For the Development And Amateur Hosting Community, A Unix Server Is A No-Brainer
Unlike the “closed” system presented by Microsoft applications and server components, a Unix-based server is constructed entirely with open source software which is updated and maintained by an active community of third-party developers and programming experts. This has a number of great side effects that directly benefit those customers who choose an open source server over one which runs the Microsoft Windows Server operating system.
First and foremost, servers based on
The second benefit of choosing an open source Unix server is that the software included with this server is more actively developed and rapidly updated. That’s because the community of developers is always submitting changes to the code, adding new features, and working on new ways of performing old tasks in more innovative and efficient styles. Microsoft is more likely to adapt these innovations several months or years later, after they have been “proven.” Its customers are rarely on the leading edge of technological advancements which benefit the web hosting industry. For web application developers and others, this is a great advantage that allows them to be ahead of the Windows “curve.” Because being ahead in technology means being ahead in profits, there’s simply no reason not to choose a Unix web hosting solution.
It’s worth noting that servers based on open source Unix technologies do not sacrifice functionality for price. These servers are a bit more difficult to integrate into today’s standard Windows or Mac OS X operating systems, but their technologies are still appropriately robust and meet the demands of both developer and enterprise clients alike. In place of Microsoft’s popular database technologies, most Unix servers ship with an adept combination of MySQL databases and phpMyAdmin administration tools that make it easy to manage data from a wide range of popular content management and interactive applications.
These servers ship with a number of email server options, which is something that Windows simply doesn’t offer. With a Unix server, the hosting client can choose the email server technology and webmail interface which works best for them, rather than merely being told which option they will use and how they will deploy that solution. Unix is all about choice and, for most people, that’s a key reason to select it over a comparable Windows hosting plan.
There’s another reason to select these open source servers, as well: In a number of key tests, Unix servers have been shown to be more capable of running many simultaneous applications and processes than their Windows Server counterparts. That might not be important to an enterprise customer who only runs Exchange and database applications, but the wider development community does value being able to multi-task in demanding and advanced ways. Those customers would be poorly served by the more crash-prone, resource-intensive Windows Server suite of tools.
Security Concerns: Not Really a Concern in the Current Era
There was one a time when Microsoft was dogged by continual security threats that challenged the integrity of both its enterprise and consumer-grade desktop operating systems and productivity tools. While the company is still the victim of more security threats and loopholes than either Unix or Mac OS X operating systems, the company’s server product is among the most secure it has ever produced. In fact, major web security firms have done extensive tests on both Windows and Unix environments; they’ve found that they’re relatively equal in the number of vulnerabilities, and the strength of their defenses, even when pursued by the web’s most notorious hacking and intrusion methods.
This is one area where it’s refreshing to see that there is little if any difference between the two major technologies that compete for web hosting clients. For far too long, choosing a Microsoft Windows server was considered technologically-smart, but not a good choice for corporate or enterprise security. The change of pace is a welcome one.
Choosing the Right Technology for Your Needs
The differences between Windows servers and those based on the open source Unix suite of applications are pretty stark. Microsoft is almost custom-designed for businesses which need a “plug and play” solution for their remote data storage and syncing needs. The company markets itself as the sensible choice for any office which primarily uses the Windows operating system, with good reason. When it comes to integrating Windows technologies, Microsoft Office applications, and remote web servers, there is simply no better option than a hosting package that runs the Microsoft Windows Server operating system. Anything else would take advanced knowledge, extensive configuration, and lots of tutorials and customer support to master.
Unix, on the other hand, presents a high-technology alternative to Windows hosting which is perfect for web developers of all levels. It combines leading-edge technology with lower licensing fees and monthly costs and lends itself to the development, novice, and budget-minded hosting community which is growing by leaps and bounds on an almost daily basis. While its technologies might not be as familiar as those found on a Windows server, they are at least as capable of performing the same tasks and, in many cases, they can actually perform those tasks in a faster and more efficient way.
Always keep in mind that choosing a web hosting technology should be subject to extensive research and planning for all scenarios. Almost every business will choose a Windows solution, but individual consumers need to keep both their needs and their budget in mind when picking either a closed system or an open source alternative. The need for lower hosting prices must be balanced with the desire for easy of use, with budget and usability winning above all else.
