Advanced Web Hosting Technology

Along with the web hosting industry comes a lot of unfamiliar terms and technical jargon.  While some are self explanatory and a bit easier to process, others are downright confusing, especially to the newcomer who knows little to nothing about the industry.  This article will introduce you to some of the more advanced terms and explain their meanings.

Availability

Often referred to as uptime, the availability of a system describes its accessibility and ability to provide a level of redundancy that works to prevent failure at any single point.  For instance, if only one server is responding to HTTP requests, the server qualifies as a single point of failure.  If there are two web servers in a load balancing scheme, then the load balancer itself is the single point of failure.  Most high availability systems are equipped with efficient fault-tolerance mechanisms to ensure the necessary redundancies.  Because 100% availability is costly and rather difficult to achieve, the industry standard in the web hosting business is at around 99.9%.

Load Balancing

Load balancing is a method web hosting providers employ to more evenly distribute the system load over a group of available servers.  This technology is used to ensure that all servers process their fair share of requests without being overworked and more susceptible to failing.  There are many types of load balancers and these mechanisms come in both software and hardware varieties.

Response time and Transaction Load

The performance of a server is associated with the response time of a given transaction load.  In regard to a website, it is measured by the time it takes to load web pages and process requests to the web server.  The performance of large, high traffic websites can be greatly enhanced by upgrading hardware, residing on a dedicated server or utilizing load balancing technology.  In many cases, fine tuning software packages such as MySQL and PHP can also increase response times.

Scalability

The scalability of a system generally refers to the property that enables it to service any given load by upgrading hardware or incorporating additional services in a predetermined manner.  It essentially describes an instance in which performance and throughput can still be maintained once the load increases.  Scalability is a great quality to have in a web hosting solution as it can support the growth and increasing needs of your website.

Session State

Session state is often needed to maintain the connection of a client program and a given server.  This typically needs to be done to accommodate a user who is logged into the system.  If the topology consists of multiple servers, maintaining session state is crucial and something that must be taken care.  Most load balancing software applications on the market provide facilities that enable this to done.  The most common methods are implementing cookies and rewriting URLs with the server details included.  load_balance.htm

Throughput

Though closely tied to performance, throughput is best described as the number of concurrent transactions the server is able to process.  The higher the throughput, the more processing power to the system.

Introduction to VDS Hosting?

The great demand for more secure, reliable services has made virtualization technology increasingly popular in the web hosting industry.  While many customers are not ready to handle the costs and responsibility that comes along with a dedicated server, more are discovering that the shared hosting platform isn’t necessarily the best choice for mission-critical operations.  VDS is the latest in virtualization, a technology that offers more control than shared hosting and the power of a dedicated server at a fraction of the cost.

What is a VDS?

Short for Virtual Dedicated Server (VDS), a VDS is created by virtualization software that partitions a single physical server into multiple isolated servers.  The result is a powerful platform that gives you the enhanced security of a dedicated server at a price that it isn’t too far off from shared hosting.  After being partitioned, a VDS is allocated with its own disk storage and data transfer for added stability.   The server has its own operating system along with isolated web server instances, a mail server and root access for custom software installations. This technology functions in a way that no matter what occurs on another customer’s VDS, it will have absolutely no impact on your environment.   Unlike its virtual counterpart VPS, a VDS is virtually like having the resources of an entire server.

VDS vs Shared Hosting

In a shared hosting arrangement, multiple websites are generally stored in a single directory.

The mere structure makes this a security risk.  With the average setup, shared customers have a dangerous level read and write access, meaning they could possibly access and modify your files. Other issues relate to stability as customers are required to share a variety of critical resources.  This includes the operating system, disk drive, CPU, memory and applications.  Depending on the severity, an error on a single account could force the entire server to run slow or even crash.  With VDS, the servers are completely isolated, giving you a level of privacy that is equivalent to running the server all by yourself.  In a VDS environment, you are completely protected from all the actions of other users hosting on the machine.

On a shared server, performance can still be an issue when no malicious actions or mistakes have been made.  For example, if one customer starts to experience a heavy load of traffic, their excessive bandwidth usage could slow down the entire machine.  This could result in a loss of HTTP requests and ultimately visitors for other customers on the server.  Additionally, the possibility of their being hundreds or thousands of domain owners on a single machine makes shared hosting very susceptible to sluggish performance.  This is especially true when many of them are using memory-hogging applications.

VDS is the perfect alternative to shared hosting as you are assured critical resources and the privacy you need from other customers.  In this environment, you will not have to worry about anyone consuming all the server’s memory and bandwidth or having the ability to view and edit your sensitive files.  The additional stability and security you get with VDS hosting makes it the next best thing to a dedicated server.

How Does Cheap Web Hosting Stack Up? A Closer Look at Your Options

Ever wonder why cheap web hosting is so popular these days?  Well for starters, it provides individuals and small businesses with a means for creating a presence online.  It makes sense – but why go cheap when you can pay for something that is more reliable?  Besides, “cheap” doesn’t have the most appealing ring to it.  Moreover, if saving money is the issue, why not cut your costs entirely by signing up with a free web host?  If you are still struggling with the concept of cheap web hosting, this article will explain why it makes a viable option between free and costly alternatives.

Free Equals Limited

Most free web hosting providers leave you very limited and are not recommended for business purposes.  For example, most of them will litter your web pages with banner and pop-up advertisements in exchange for their free service.  This can be a huge distraction to the people who come visit your website.  Many of them also limit you in terms of ownership.  Sure, they may provide you with a domain, but it is generally attached to their website, leaving you with a name that is both hard to remember and unprofessional.  Last but not least, free web hosts typically provide you with minimal bandwidth and disk storage.  Once you start to generate traffic and popularity for your site, you will eventually exceed the allotted resources and have no choice but to upgrade to a premium package.

More Freedom at a Great Price

The limitations of free web hosting is what leads most individuals and businesses to more flexible yet affordable solutions.  Cheap hosting delivers the features and flexibility you need at a price that is easily within reach.  With so many providers offering service, several companies price their plans considerably low to keep pace in the highly competitive web hosting industry.  Play your cards right and you can find a host offering service for under $10 a month.  It isn’t hard to get yourself a package with a generous supply of disk space, bandwidth and features.  Today’s cheap web hosting services are geared for individuals and businesses, providing email accounts, e-commerce applications and everything needed to open an online storefront.  These plans are widely available so why pay extra for something that could end up setting you back?

Don’t Forget the Essentials

Cheap web hosting offers many benefits but it can also be a disaster if you overlook some of the critical aspects.  Even though you are paying less for service, your hosting account should still come with acceptable customer service and technical support.  Getting answers from the experts is important as your customers will surely be needing an explanation from you if something should go wrong.  Additionally, you should never  go for any cheap web hosting plan that advertises an uptime guarantee less than 99.9%.  Excessive downtime is something you can’t deal with as it is the best way to cripple your web presence.  When knowing what to look for, you can go in on a strict budget and come out with a great web hosting package.
