Web Hosting - Is a Dedicated Server Worth What You Pay?
In reviewing web hosting plans, many web site owners are faced at some point with the decision of whether or not to pay for a dedicated server. A dedicated server is one which holds your site(s) exclusively. It's not shared with other sites. You then have the option to put one site or many on that piece of hardware.
But the decision is never easy. There are multiple considerations to take into account, far beyond just the higher dollar outlay that inevitably accompanies a dedicated server option.
Performance is (or should be) a prime consideration for the majority of site owners. Studies show that when a page doesn't load within about 10 seconds or less, almost everyone will give up and go elsewhere. The delay may be caused at any of a hundred different points in the chain between the server and the user. But often, it's the server itself.
In any case, it's important to eliminate the server as a possible bottleneck, since it's one of the few points over which the site owner can exercise some control.
That need for control extends further than just performance, however. Other aspects of the user experience can benefit or suffer from server behavior. Security is a prime example. With the continuing prevalence of spam and viruses, a server can easily get infected. Having only your site(s) on a single server makes that issue much easier to deal with.
With fewer sites on a server, there is less likelihood of getting infected in the first place. Also, since you will place a higher value on security than many others, it's easier to keep a dedicated server clean and your site well protected. You can use best practices in security to fortify your site. Having other sites on the server that you don't control raises the odds that your efforts are for nothing.
One way your efforts can get watered down is through IP address sharing. Less sophisticated hosting services will often assign a single IP address to a single server and multipe sites. That means your site is sharing the same IP address with other domains. That leaves you vulnerable in several ways.
Virus or spam attacks may target a particular IP address. If you have the same one as another site, one that is more likely to attract hostile intentions, you suffer for and with someone else.
In other cases an IP address range is assigned to the server, with each site receiving its own address from within that range. Though better than the one IP:server scenario, this still presents a vulnerability. Many attacks try a range of IP addresses, not just a single one.
But even legitimate sources can give you trouble when you share an IP address or a range. If another site engages in behavior that gets it banned, you can suffer the same fate if they ban the address or range. If the miscreant that shares your server/IP address or range is himself a spammer for example, and gets blacklisted, you can inadvertently be banned along with him. Using a dedicated server can overcome that problem.
There's a certain comfort level in knowing what is installed on the server you use, and knowing that you alone put it there. But a dedicated server option may require increased administration on your part. If you're not prepared to deal with that, you may have to pay still more to have your dedicated server managed by someone else.
All these factors have to be weighed carefully when considering a dedicated server plan.
Web Hosting - Changing Web Hosts, Pitfalls and Planning At some point, nearly everyone finds it necessary to change web hosts. It may be just a migration to another server, or it may be changing web hosting companies entirely. Either way, the process is fraught with potential dangers. But there are ways to minimize the odds of problems and maximize your changes of a smooth migration. Plan, plan, plan. Make a very detailed list of everything that is on your current system. Review what is static and what changes frequently. Note any tailoring done to software and files. Be prepared to remake them if the systems aren't transferred properly or can't be restored. Keep careful track of all old and new names, IP addresses and other information needed to make the migration. Backup and Test Backup everything on your system yourself, whenever possible. Web hosting companies typically offer that as a service, but the staff and/or software are often less than par. Often backups appear to go well, but they're rarely tested by restoring to a spare server. When the time comes that they're needed, they sometimes don't work. Do a dry run, if you can. Restore the system to its new location and make any needed changes. If you have the host name and or IP address buried in files, make sure it gets changed. This is often true of databases. SQL Server on Windows, for example, picks up the host name during installation. Moving a single database, or even multiple ones, to a new server is straightforward using in-built utilities or commercial backup/restore software. But moving certain system-related information may require changing the host name stored inside the master database. Similar considerations apply to web servers and other components. Accept Some Downtime Be prepared for some downtime. Very few systems can be picked up, moved to another place, then brought online with zero downtime. Doing so is possible, in fact it's common. But in such scenarios high-powered professionals use state-of-the-art tools to make the transition seamless. Most staff at web hosting companies don't have the skills or the resources to pull it off. Prepare for Name Changes One aspect of moving to a new host can bedevil the most skilled professionals: changing domain names and or domain name/IP address combinations. When you type a URL into your browser, or click on one, that name is used because it's easier for people to remember. www.yahoo.com is a lot easier to remember than 209.131.36.158. Yet the name and or name/IP address combination can (and does) change. Still, specialized servers called DNS (Domain Name System) servers have to keep track of them. And there are a lot of them. There may be only two (rarely) or there may be a dozen or more DNS servers between your visitors' browsers/computers and your web host. Every system along the chain has to keep track of who is who. When a name/IP address changes, that pair has to be communicated to everyone along the chain, and that takes time. In the meantime, it's possible for one visitor to find you at the new place, while another will be pointing to the old one. Some amount of downtime will usually occur while everything gets back in sync. The Little Gotchas But even apart from name and IP address changes, there are a hundred little things that can, and often do, go wrong. That's not a disaster. It's just the normal hurdles that arise when changing something as complicated as a web site and the associated systems that underlie it. Gather Tools and Support Having an FTP program that you're familiar with will help facilitate the change. That will allow you to quickly move files from one place to the next to do your part to get the system ready to go or make repairs. Making the effort to get to know, and become friendly with, support staff at the new site can be a huge benefit. They may be more willing to address your problem before the dozen others they have to deal with at any given moment. Ok. On your mark. Get ready. Go. Web Hosting - Do It Yourself Administration, Things to Consider The choice of whether or not to try to administer your own web site brings with it a host, pun intended, of issues. For most web site owners, the primary focus is naturally on creating, maintaining and enhancing the site. That often is just part of managing an entire business, for which the web site is just the means to an end. That implies there will be little interest in or time left over for technical administration like database maintenance (tuning, space management, security, bug fixes), establishing and maintaining backups to ensure they're successful and usable, email administration, disk space management, applying operating system fixes for bugs and security, and other tasks. But cost is always a factor in any business. Paying for technical help can burden the budget of a new and struggling business. Consulting fees can range from a few dollars an hour to over $100. On the lower end, the poor skill level and quality of work will make it not worth even that small amount. On the higher end, you can quickly rack up expenses that will bust your business. Permanent employees are usually somewhere in the middle of that range when you add up salary, employment taxes and more. Often, server and/or web site administration can be paid for as part of the web hosting package. That cost is usually lower than independent contracting help, but those staff are usually tasked with maintaining dozens if not hundreds of servers and sites. They can, therefore, give very little individual attention to yours. Often, novice web site owners are intimidated by some of the technical requirements for server or site administration. But, as with anything, a little familiarity can show that the knowledge required is more modest than one might expect. Administration in many cases involves fairly elementary, and frequently repetitive, tasks. These can be learned easily. Using a test site or a free hosting service is a good way to practice and learn without risk or cost, other than time invested. Once that initial hurdle is jumped over, administration can be done quickly and some even find it interesting. It allows the site owner to exercise additional control over the total product, and there's satisfaction in being able to say 'I did that' even if you prefer not to do it forever. That real-life learning experience also allows the site owner to better judge any consultants or staff that are hired. It's much easier to judge if someone is providing you with an accurate assessment of a problem if you've solved it yourself. Any time-estimate they provide to fix it can also be better calculated if you've had to do it yourself. Every web site relies on a variety of factors, usually unseen, in order to continue to function properly. But the fact is that they misbehave from time to time. Deciding whether to tackle those problems yourself depends on your available time and skill set, and what it will require to get things back on track. In other words, it's a standard cost-benefit analysis that everyone has to undertake every day in life. |
