If you are making a comfortable living from the Internet and the Web or have a plan to achieve that goal, it's likely that you are running more than ten websites. The websites are your virtual offices. You want to your sites to be up and running 365 days, 7 days a week and 24 hours a day. Managing multiple websites is a daunting task if running one website is a hobby.
Proposed Hosting Strategy for Managing Multiple Websites
The hosting strategy we propose is to host your multiple major websites with 3-4 different hosting companies, and open a reseller account with another hosting company for 1) small and new websites, 2) web development and 3) backup. Hosting with too many hosting companies will significantly increase the time and the difficulty of managing sites, and using a single hosting company isn't a smart choice either.
Justification of the Hosting Strategy
Cost - Cost of the Web hosting isn't an issue for running a single web site whether it costs $5 or $25 a month. The difference is only a few hundred dollars or less a year. It's always nice and smart to get the most out of every single dollar in doing business. At least, a few hundred dollars difference wouldn't make or break a business. If you run 10 or even 50 websites, the cost of Web hosting alone will define the success or failure of your online adventure. To cut the hosting cost, the option is to use a reseller hosting account to host as many small or new sites as you want for about $15 a month. You host one or 2 major websites with one hosting company. Shared hosting account costs under $10 a month, and dedicated server will cost $50 or more a month.
Uptime - If your bread-and-butter maker website is down for a few hours, you'll lose hundreds of dollars and more. Even though most hosting companies promise 99.9% uptime, it's not common to see a website down for a few hours. A site could be down for a half day or even more if a hosting company is doing a major update. The hosting company may do the update in a weekend or a major holiday, but that's when many family-oriented and travel sites generate their revenues. If you could afford the loss of revenues, many websites owners can't bear the psychological loss and pressure. Hosting your sites with a few hosting companies will reduce the risk of downtime.
Application Development - For simple web application, webmasters will do development on the same production hosting site. If your ecommerce applications are complex, doing development on the production site may bring down the live site especially if you're in the process of changing configuration files or install customized applications. The option is setup a website on your reseller account for development and testing, and move the applications to production account on another server after the completion.
Backup - If you're not happy with a hosting company, a hosting company is out of business, or the servers will be down for a day or two, you can easily temporarily or permanently switch from one hosting company to other since you're familiar with the site managing tools already. If you have a backup or secondary copy running on another server, all you need for the switch is the transfer of the domain, which will take no more than a minute.
