Importance of Cluster computing in business world

The spurt of the internet and diverse e-business applications has stalwartly affected virtually all IT companies. Sometimes applications require more computing power than sequential computers can offer. An effectual way to deal with such technical issues, it is imperative to augment operating speed of various components of computers such as processors. A feasible and lucrative solution is to connect multiple processors together and synchronize it. With the advent of information and communication technology in modern era, cluster computing has revolutionized the companies and has great influence on customers. 

Cluster computing was evolved in the 1960s by IBM as a substitute to link huge mainframes to offer cost effective form of technical system.
A computer cluster is a pool of closely combined computers that work together efficiently and visualized as a single computer. Key components of clusters are generally linked to each other through fast local area networks (LAN) with each node (computer used as a server) operating its own instance of an operating system.

Clusters have developed to support myriads of applications that range from ecommerce, to high performance database applications. Computer clusters are adopted by majority of companies to improve processing time, faster data storing and repossession time. These computer clusters can be categorized in three types of clusters to outshine performance or reliability. These include high performance clusters used for computation-intensive applications, high availability clusters are used to improve the availability of the cluster approach and load Balancing clusters in which computational capacity is shared between the nodes to increase overall performance such as in web server cluster.



There are numerous advantages of embracing cluster computing technology. Companies espouse clusters computing technology to increase speed and/or reliability provided by a single computer as well as it is viable cost effective solution to enhance technical competence. Other key benefits of cluster computing are that a computer cluster can be advanced to a higher specification or expanded by adding extra nodes.

Despite of advantages, there are several limitations of cluster computing. Companies may suffer from programmability Issues when some components are different in terms of software from each other, and then issues emerge when combining all of them together as a single entity. Another drawback of this computing is locating fault because it is operating as a single entity. Other issues develop when it is dealt by an unprofessional person as cluster computing involves amalgamation of different or same components together with different programmability.

Cluster computing is extensively used in the fields of educational resources, Commercial sectors for industrial promotion, and medical research.
In ending the dialog, cluster computing has revolutionized the face of computation. It comprises of loosely connected or tightly coupled computers that can be operated as a single system by the users.  Such computing systems guarantee unremitting performance in fierce competitive global markets

Stem Cell therapy for Neurological Disorders: Life saver or threat

Image
It is claimed in medical reports that stem cells is used in patients suffering from neurological disorders. But it is a stormily debate among researchers and medical experts. Some view this therapy as a lifesaving capsule where as others feared about the consequences of inducing this treatment. Today, people are excited to know that medical specialists have options to treat irreversible ailment of the brain such as onset neurodegenerative disorders like Parkinson’s disease, younger onset inflammatory diseases such as multiple sclerosis or even conditions in which there is an inborn fault of metabolism. Stem cells are part of the body’s normal repair system which substitutes dented or dying cells where possible. In Stem cell therapy, medical experts introduce cells into the damaged tissue in order to treat the disorder or the injury. Stem cells have not yet developed to perform a particular function and are described as unspecialised. Each stem cell has capacity to develop into ...
