How to Select the Approprite Load Balancing Technology

Load balancing is a hot topic in the web hosting industry as the technology is being increasingly used in server farms and shared hosting environments.  Its purpose is to fine tune computer systems and networks in a manner that better evenly distributes data and processing across available resources to prevent a single device from being overloaded.  Some of the busier websites utilize two or more servers in a load balancing scheme. Therefore, if one is overwhelmed, traffic is forwarded to another with more capacity.

Common Types of Load Balancing

The process of load balancing is one that can be achieved in a variety of ways.  If this is a technology you are interested in, it is best to know what methods are available to you.   After learning a little more about the types of load balancing, you will should be able to better determine which option works best.

Round Robin DNS Load Balancing

One of the earliest adopted techniques, round robin DNS load balancing uses the round robin feature built into the BIND DNS server to facilitate cycles through the IP addresses corresponding to a farm of servers  This is one of the easiest and most inexpensive methods to implement.  The downside to this type of load balancing is that the DNS server doesn’t have any knowledge of the server’s availability.  Therefore, there is a possibility that data could be continuously forwarded to an unavailable server.  There is also a chance that an IP address will be cached by other nameservers and not sent to the server designated for load balancing.

Hardware Load Balancing

With hardware load balancing, TCP/IP packets are routed by a device to numerous servers in a cluster, a method that leverages circuit level gateway to route traffic.  This method is said to create a powerful topology with a high level of availability.  The one big drawback is a cost that is often considerably higher than other methods.

Software-based Load Balancing

The software-based variation is the most commonly used load balancing method.  These type of load balancers are typically integrated as components in proprietary web servers and application server platforms.  This technique is more configurable and offers the ability to implement intelligent routing based on various input parameters.  In many cases, software-based load balancing requires additional hardware be provided to isolate the load balancers.

Narrowing Your Options

The decision of choosing a load balancing configuration based on hardware or software should be made on one’s particular needs.  For instance, if your website only requires load balancing to serve HTML pages or lightweight dynamic, data-driven pages, the round robin method should be sufficient.  On the other hand, if your traffic and data processes are more demanding, you would probably get the best performance out of the more advanced software or hardware methods.  Whatever method you take, keep in mind that the load balancer should be able to deliver intelligent monitoring to evenly distribute the load.  Depending on your situation, different techniques can better direct the loads to the servers that are more capable of handling them than others in the cluster.

Critical Factors to Consider When Evaluating Application Hosting

Application hosting services are increasing in demand as more business come to realize that outsourcing to a qualified managed service provider can greatly enhance the deployment process and reduce costs across the board.  To help you find a service that meets the needs and expectations of your organization, we have listed some of the important factors that must be considered for an application hosting solution.

Storage Requirements

Because storage can be a rather costly proposition, it is best to take a just-in-time approach towards your inventory.  By answering the questions below, you can draw a more accurate picture that might defer costs until they are absolutely vital:

- How much storage do you need now?

- How much storage will you need in the next 3 to 5 years

- How much additional storage will you require each year?

- Will you need to archive data and pull it from the main storage area?  If so, how much and when?

Applications to be Hosted

How many applications do you need to host and what type of applications are they?  Staging, testing, development and deployment are just some of the environments you may need hosted.  In most cases, each environment has different hosting requirements in terms of availability, operational tasks, access and support.  Make sure you assess the use and flow of data within and between these applications to precisely determine the requirements for each one.

Backup and Restore and Disaster Recovery

Before deciding on an application hosting provider, it is critical to define what is to be backed up, when and how often.  When focusing on this area, it is also a good idea to keep disasters in mind and think of what would happen if something bad occurred and the provider’s data center became completely unusable.  This is a place where you need to put a business continuity plan into effect.

SLA Monitoring and Reporting

Key performance indicators come in handy, but only when they detail what is important to your organization.  Make sure you know what levels of availability the service level agreement covers as well as the applications that will be monitored.  If monitoring reports are available, find out how they are to be structured and provided.

Root Access

System root access usually isn’t given to parties outside of the data center staff.  It is also important to know that some application providers will waive their SLAs if they can determine that a non-root access account is the cause of an outage.  Because this can have a major impact on your availability, it is vital that you inquire within the provider about their root access policies before signing the contract.

The Service Contract

When it comes to application hosting, contracts define much more than what products or services will be provided and how much they cost.  They also explain how organizations are to interact with each other.  It is wise that you go over the contract with a fine tooth comb to prevent confusion and enable a framework for dispute resolution and continuous enhancements.

Finding the Perfect Balance of Disk Space and Bandwidth

You will find thousands of articles online stressing the importance of disk space and bandwidth.  Many hosting companies will try to persuade you into buying the package that offers the highest allowance of both.  Having a large amount is good but do you really need it?.  If you are not sure, you need to find out how to carefully balance the two.

In order to estimate how much disk space and bandwidth you need, you should first determine what type of website you will have.  In general, small business sites fall into one of the following classifications.

Mini-sites - Also referred to as one-product sites, min-sites are small and usually consist of two to three pages.  The main focus of such a site is to sale a single product or collect contact information from visitors and try to market products to them at a later time.  This is the type of site you often find with a lengthy sales letter along with an order form and contact page.

Brochure Site - A brochure site typically has about 10 web pages that describe what the business does.  It goes over their products and services, location and targeted market among other details.  The site might also contain a contact page, an about page and other pages where items can be purchased.  These sites get their name because they essentially act as the company’s online brochure.

Theme-based Site - This type of website revolves around a specific niche market or topic.  It could be a site dedicated to freelance writers, web hosting or work-at-home moms.  These sites usually receive frequent updates and contain articles, tutorials and other resources.  A theme-based site can either sell its own products, items from affiliates or simply exist to provide a lot information.

Each website classification has different disk space and bandwidth requirements.

A mini-site usually does not require an enormous amount of disk space. On the other hand, if it starts to gain popularity through effective search engine optimization, affiliate promoting or word of mouth, it will likely generate more traffic.  In this instance, the amount of bandwidth becomes crucial.

A brochure site does not require a lot of disk space or bandwidth.  This is the average small business site, one that can get by with the basic offerings of a good web hosting provider.

A theme-based site usually does not require that much disk space or bandwidth.  In the beginning that is.  If this is a website that truly requires frequent updates, the requirements for disk space can increase quite fast.  Moreover, once you add more content and generate more traffic, your needs for data transfer will also increase.

Regardless of what type of site you have in mind for your small business, it is a good rule of thumb to expect the unexpected and take the future into account from day one.  The best thing you can do in any event is to make sure your host doesn’t charge ungodly amounts for overages and provides an easy path to service upgrades.
