Cluster computing and Load Balancing are two of the most familiar terms when it comes to the world of technology and computing. It can get a bit similar at times, but there are very distinct differences between the two. While cluster computers are a range of built in and connected computer systems, Load balancing is the devices which are used to augment the outcome from the clustered computers. This article is set to make you understand the concept of cluster computing and load balancing development.
A computer cluster or otherwise known as cluster computing are a set of computers that are connected and wired together so that they work together. They are often viewed as a single system even when there are a number of computers connected. The computer clusters are modelled in such a way to perform the task through each node set under the applied software. The different components of the cluster are wired and connected via a fast Local Area Network.
The computer cluster technology garners the following features:
- The cluster computing solely relies on a centralized management system and work through shared nodes and servers.
- They are not the same as that of the grid or peer to peer computing which also uses nodes but is different due to its varying and distributed nature.
- The computer cluster may include the least of just two computers to a number of computers for fast and efficient work.
- The activities of the cluster computing are achieved through the “clustering middleware” which is a form of software that allows the clustered computers to work efficiently and with ease.
The benefits of using cluster computing are:
- It allows a simple scalability through its efficiency and low maintenance.
- The centralized management is very useful for fast outcomes with little to no hassle.
- This also provides help in processing the parallel data and also enables data recovery in times of server breakdown.
Now that you may have a fair idea about what cluster computing means, let’s take a look at what Load Balancing refers to. Load Balancing uses devices which help in distributing the workloads across all the connected computers in the cluster. They include a number of software or hardware to increase the efficiency of the work output.
The main features of Load balancing are enlisted below:
- One of the main characteristics of Load Balancing is to optimize the resource use to a maximum.
- It also helps in maintaining a minimum response time and also reduces the loading time of any page.
- It uses multiple components in order to increase the reliability through redundancy.
The load balancing is very much important when it comes to increased efficiency of the cluster computing and here’s why:
- It is very useful in applications which have several redundant communication links.
- The use of load balancing helps in increasing the available bandwidth of the server when multiple links are used in place of single link.
