High Traffic Website Web Hosting Requirements
Getting a site a great deal of traffic is no simple matter, likewise, neither is finding a hosting company for a site that is well promoted. When you’ve spent the time to drive traffic to a website, the last thing you want is for that website to go down. As the old saying goes, time is money, and the right web host can make a big difference when it comes to your site. It is the intention of this article to provide information regarding what sort of options a good web hosting company will provide to a high traffic site.
As you can see, these technologies can be quite expensive, which can translate into high maintenance costs from your web host. And much like strapping a jet engine onto the back of my Ford Fusion probably isn’t a good idea; neither is buying a ,000 web accelerator for your simple brochure site. So, in order to choose between what is necessary and what is overkill, here is what you’ll need to know:
Load balancing for a web application is a great tool for both availability and performance. A Load Balancer stands in front of the web servers, creating a virtual address to which the client connects. It then distributes traffic evenly over the web servers to reduce the load on any single server. If one of the web servers is not available, the Load Balancer will detect the failure and reroute the traffic to all of the remaining available servers. It also provides a layer of security by hiding the real IP addresses of the application servers.
Who Needs it:
Load Balancers on a Budget
If you must have a load balancer but can’t really afford the separate appliance option, there is software available that will do the trick for a fraction of the price. This solution is not as efficient or robust as the hardware solution, but still affords the benefit of availability and is better than not employing a load balancer at all.
Web Accelerators use technologies such as caching and compression to deliver data to a large user community faster. It mitigates pressure on your system by storing data that otherwise will be transmitted repeatedly and delivering it straight from the cache.
Who needs it:
SSL Accelerators, also like Load Balancers, stand in front of application servers. They handle the encryption and decryption of a secured communication and eliminate the need for multiple SSL (Secured Socket Layer) certificates, reducing the load on your web servers as well as the administrative costs of SSL certificates. An SSL Accelerator can be purchased as a “module,” meaning a smaller piece of equipment that can be plugged into the primary appliance consolidating your equipment.
Who needs it:
For best availability, your web host should offer all of these solutions on High Availability (HA) packages. HA is the ability to have two or more appliances that are failover capable such that if one of the appliances becomes unavailable the other picks up the load.
With HA, you can eliminate the risk of a single point of failure in your network.
Most of these technologies are more efficient and easier to maintain when implemented at the hardware level. The appliances can be pricy, but you can find good deals on refurbished and second hand equipment. Support is also quite expensive so keep it in mind.
When it comes to availability redundancy is key. It is highly recommended that your host give you the option for all applications to run on at least two servers. If you can’t afford two servers, make sure you’re constantly backing up your data someplace else!
When it comes to performance, it’s all about hardware. Here are the fundamental elements that will make your systems run faster:
Finding a web host that can create a highly available and performance driven network is a daunting task for any webmaster regardless of budget. These recommendations hopefully have given insight into how anyone can achieve excellent results in performance, and what sort of hosting upgrades can be made to super-charge your site. Keep informed of new technologies and try to find a knowledgeable partner that is willing to do the research for your business.
