Server Load Balancing

Incoming Traffic! We Have Incoming Traffic!

Traffic. In our Internet-centric world, traffic is almost the end-all be-all of conversions. Just as if you ran a small mom and pop grocer establishment, getting people in the door is more than half the battle. Incoming traffic to a website is the equivalent of customers entering your mom and pop shop. The more traffic – the more customers you have – coming in and viewing your merchandise, the more you have a chance of making a good profit. But let’s say getting people in the door isn’t your problem. Let’s say, your problem is handling all of the traffic coming into your site because you just created the single greatest service on the market today. Whatever you created – a never ending energy supply – is having such an impact on the market that you can’t keep people from entering your store and ripping all the merchandise from the shelves. In this equation, your online website, due to all the increased traffic, might experience downtime. Your site, like your store, due to the overwhelming demand, might falter causing you to loss business and suffer a large reputation hit.

It goes without saying, but when you have lots of customers – tons of traffic – the last thing you need is for your website to fail. Due to this, you need to understand the concept of server load balancing and more importantly, how it can save you from experiencing a hard hit to your sales and reputation.

What is Load Balancing?

Load balancing, sometimes called Server Load Balancing or Network Load Balancing, is the process of distributing incoming traffic across multiple virtual machines (VM’s) to ensure your machine – by extension your website – does not fail under peak traffic influxes. Think of server load balancing as an experiment in breaking water surface tension. In this hypothetical experiment, you place five lily pads on top of a stagnate surface of water. Following placement, to test the surface tension which allows the lily pads to continue floating, you begin to place small pebbles on one of the four pads. As you add more weight to the one pad it begins to show signs of breaking and sinking. Due to the growing weight, the pad is still floating but the surface tension of the water is slowly breaking. You can see signs of this from the middle of the pad dipping further into the water. Finally, after enough pebbles are placed on the pad, it slips below the surface of the water. However, if this process were to play out again wherein you placed equal amount of pebbles on each pad as opposed to one, all pads would stay afloat without any failure. This is load balancing. Spreading load, spreading incoming traffic across multiple servers to ensure each servers uptime.

But What if My VM Does Fail Under Increased Duress?

Fail safe. Remember that word when it comes to server load balancing and network load balancing. The truth of the matter is sometimes, regardless of precaution, your server – your website – might fail. Maybe your traffic spikes quickly enough that the pebble experiment doesn’t hold water anymore (sorry, little pun there). In this situation, traffic spikes so quickly that although load balancing is taking place, one of your VM’s fail. In this cause, server load balancing acts as a fail safe to keep your website up and running. In the case of VM failure, server load balancing transfers incoming traffic to the remaining servers under the aforementioned load balancing method. As mentioned by our Dedicated Server page,

“Solutions deployed with DedicatedNOW use a host of advanced services to ensure that your hardware and network environment scales to whatever user load you may require. Load Balancing enhances redundancy by distributing the load on a single server across multiple servers. Should you experience hardware failure on one server, our load balancing solution will push your visitors and processes to a redundant server to keep your website online. Clustering works in tandem with load balancing by coordinating the resources of several servers, for use in a single application (i.e. hosting a database-driven website). DedicatedNOW is expert at delivering high-availability infrastructure aimed at providing the maximum in redundancy and reliability.”

Never Ending Energy

Bringing this full circle, your newly developed never ending energy supply – cold fusion – has just hit the market and customers are pounding down the doors to get their hands on it. By utilizing scalable load balancing solutions for your dedicated server hosting needs, you won’t have to worry about your customers being locked out of your ecommerce website due to spiking traffic. With network load balancing (spreading out your traffic over a network) and server load balancing (spreading your traffic across multiple VM’s) you can supply your cold fusion to the world without downtime worry.

And now, if you don’t mind, we have to go fish out a few lily pads from our in house science experiment tank. We love everything Web Hosting and Cloud Hosting but truth be told, we are large nerds who love nothing more than safety glasses and beakers. Until next time.

Docker offers a new, lightweight approach to application portability. Applications are shipped using a common container format and managed with a high-level API. Their processes run within isolated namespaces that abstract the operating environment independently of the distribution, versions, network setup, and other details of this environment. This "containerization" has often been nicknamed "the new virtualization." But containers are more than lightweight virtual machines. Beyond their small...
The move in recent years to cloud computing services and architectures has added significant pace to the application development and deployment environment. When enterprise IT can spin up large computing instances in just minutes, developers can also design and deploy in small time frames that were unimaginable a few years ago. The consequent move toward lean, agile, and fast development leads to the need for the development and operations sides to work very closely together. Thus, DevOps become...
An entirely new security model is needed for the Internet of Things, or is it? Can we save some old and tested controls for this new and different environment? In his session at @ThingsExpo, New York's at the Javits Center, Davi Ottenheimer, EMC Senior Director of Trust, reviewed hands-on lessons with IoT devices and reveal a new risk balance you might not expect. Davi Ottenheimer, EMC Senior Director of Trust, has more than nineteen years' experience managing global security operations and asse...
The definition of IoT is not new, in fact it’s been around for over a decade. What has changed is the public's awareness that the technology we use on a daily basis has caught up on the vision of an always on, always connected world. If you look into the details of what comprises the IoT, you’ll see that it includes everything from cloud computing, Big Data analytics, “Things,” Web communication, applications, network, storage, etc. It is essentially including everything connected online from ha...

The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs. In this Power Panel at 15th Cloud Expo (http://www.CloudComputingExpo.com...
