DNN Guide Enterprise Distributed Load Balancing

Distributed load balancing is a networking technique that allows distributing the workload on various servers to maintain and sustain the performance of the website and avoid overloading. It is the type of networking which enhances the liability of a website to be live even if there is intense pressure coming over it from high traffic or any other reasons.

Before going in-depth about DNN load balancing, you need to know that what load is balancing. The most straightforward answer to this question is that load balancing is all about distributing inbound network and traffic across many different servers. There are hundreds of user requests or client requests in the internet world that come up on a website. It becomes pretty hard for one server to keep up and continue to display text, video, HD quality images, and other data at a speed that many users need to be accustomed.

In this whole process, lags are considered unacceptable, and complete downtime is unbearable. Many different load balancing techniques serve as an instructor to direct the traffic to specific servers in the server farm. Conclusion this thing helps prevent one server from carrying too much load and ensures the optimization of network and application availability and responsiveness on the website.

Other than the functionality of load balancing, you should also be aware of the security side. Cloud is pretty popular these days, and due to that, there is an application load balancer that can be used for preventing the denial of service attacks. In the cyber sector, denial of service attacks is the most common threat. They can disrupt the flood of traffic that can cause a nightmare for IT experts to manage. A load balancer, application, and network traffic from a server can be distributed to a cloud server, which can protect the traffic from the interference from multiple dangerous cyber-attacks. So, the load balancers are essential for improving the performance and ensuring the security of a website's content in DNN.

Benefits of DNN Load Balancing

Boosts up the Servers' performance with its excellent features of distributing a load of traffic on the website on multiple servers, it is the best way to improve the servers' performance. When the load is not on only one server, its version of the server will not be affected. Too much load on one server can result in its tripping and lousy performance. So, it is one of the main benefits of DNN load balancing.

In DotNetNuke, load balancing can also be stated as a web farm configuration. That web farm configuration that DNN supports on the initial level is two or more than two front. Web servers can also be referred to as webheads, and whose IIS website directories can be mapped to a common UNC share on any remote file server. The UNC share consists of the application source code and any static content for some individual sites.

UNC share has application source code and also any static content for different individual sites as well. Over there, every web server gets connected with a remote database server for getting dynamic application content from them. In this configuration, you can also remove any web server from the farm without even creating any disturbance in the users' services who are browsing those sites.

Above mentioned primary method for support can provide the best consistency and reliability in managing files and keeping them in a synchronized way among all the machines on the farm. In some alternative configurations, however, the servers can be configured for using file replication services. In that case, there cannot be any central file server; instead of that, every web server carries its directory that is mapped to a local folder for access. In DotNetNuke, this setup is just slightly different, but the functionality is the same.

Types of Load Balancing

Now you know all about what is load balancing and knew its benefits as well. So now, we will discuss its types. There are many different load balancing strategies you need to consider when you are setting up your network.

• Network Load Balancing
  As the name suggests, network load balancing is about leveraging the network layer for deciding where to forward the network traffic. Layer 4 load balancing is used to accomplish this load balancing as it is designed to handle every form of TCP traffic. It is considered the fastest among all, but it can trip when the traffic is distributed across servers.
• Internal Load Balancing
  The inner level of load balancing is just like network load balancing, as it covers the load internally. Rather than network load balancing, this can be used for getting the internal infrastructure balanced.
• HTTP Load Balancing
  This load balancing technique is one of the oldest ones, and the load balancing of this form entirely relies on layer 7, which means it operates in the application layer. It is known as the most flexible and adaptable type of load balancing. It is because it can allow you to make the distribution decisions based on the information coming with an HTTP address.

Types of Load Balancers

Indexing simply refers to the method of indexing all the contents (or allowed contents) of a website. It also refers to the database used by search engines which contains all the information on a website found by the search engine. Once your page or website is not indexed by a search engine, your page or website will not be found or seen by users.

• Software Load Balancer
  Software load balancer is found in two forms, commercial and open-source ones. These load balancers need to get installed before using them. Cloud bases balancers come in this category, and these are affordable and flexible.
• Hardware Load Balancer
  As you can get it by its name, the hardware load balancer comes with physical and on-premises hardware for distributing the application and network traffic. The benefit of using them is that you can manage a large volume of traffic with them, but they are expensive ones and are also not much flexible.
• Virtual Load Balancer
  It is different from a software load balancer as it deploys the software of hardware load balancing on a virtual machine.

Load balancers are for distributing the load for a particular website of upcoming traffic on multiple servers. The load balancers have many benefits, and they can handle and manage the traffic volume effectively and with high efficiency. This way, the traffic coming to a website can be divided into increasing servers' high performance, and only one server is not overloaded.
