Application of load balancing is used by different companies that conduct huge business transactions using internet. It is normally done to ensure that all their clients are able to conduct business activities with ease and accuracy.

Even companies who are maintaining large number of computer network for single user use load balancing to ensure that each computer is performing well and has the correct amount of power to be able to perform functions that are intended for particular work. Benefit of load balancing is, if one of your server goes off then you have other the option of alternate server to work upon.

Load balancing improves the performance of server due to distributed load and is used for busy and large networks .Without balancing load in busy networks it is very difficult to satisfy the entire request issued to server. Organization into the web services or online business normally makes use of load balancing technique and engages two web servers ( or more servers accordingly ) . If one of the web server gets overloaded or goes off, in that case alternate server activates and access the requested load.

Load balancing is done by assigning particular service time for each process in order to ensure that several requests are handled without causing traffic. In other words, specific time is assigned to each process in the server for its execution and the process no more stay in the server once service time extends. Once load balancer works actively, service time reduces for each process reduces.

Lets discuss various techniques widely used for load balancing. The most popular technique is global server load balancing .This method distributes the work load of incoming tasks to group of servers in particular location. Such technique is used by companies that have global presence and are very much customer oriented.

Global server balancing technique ensures that the work load is evenly distributed throughout server system and all locations are receiving correct data from right set of server. Congestion and huge volume of traffic is always a problem in large network systems due to excessive load on the system . Technique of persistent load balancing can drastically help to minimize congestion on large network.

Another load balancing technique is Persistent load balancing technique. This load balancing technique does not make any use of software or hardware node and the customer is allowed to select their respective server and get services from that server. This process is very transparent and useful from client point of view as it discloses the presence of multiple servers at the backend . This technique assigns each new client with different set of server on a round robin allocation basis. This process of load balancing ensures that each new client is assigned with specific server and no server is overloaded with particular client.

Professional network engineer or server administrator who is given the responsibility for maintaining smooth server functionality should be very experienced and qualified with complete knowledge of server like handling installations, maintenance, security, troubleshooting and operating system of server .

Server is the vital and crucial part, as all the applications are linked with it and entire operations of the organization is dependent on server. So round the clock monitoring is required for smooth operation of server and smooth operation of organization.

Depending on the application and configuration, servers are designed by various companies like Microsoft, Cisco, Sun etc and all the servers use different technologies and features to satisfy customer demands and requirements. It is necessary to appoint system administrator possessing complete knowledge of server regardless of brand and company .Verify credentials in handling various job roles like system administrator, network administrator, information system administrator, network analyst, network engineer and desktop specialist. This is done to ensure that person is capable of handling any type of situation in case of emergency.

Now days, there are various software available to monitor server activities and to prevent server from malfunctioning. After fixed interval of time, it checks and ensures that all the functions are working and if due to some reason stops working, it will reset them. System Integrity monitor by RFX networks is one such software used to monitor server functionality. Few features of System integrity monitor program:

• Informative command line display
• Ability to auto restart system with definable vital load level
• Event tracking and alert system
• Check against network sockets and process list to ensure that all services are online
• Latest and advanced HTTP service monitoring , to protect commonly encountered issues
• Auto ability restart feature for downed services

Sever monitoring is crucial aspect for companies into online business that conduct huge business transactions using internet and for companies that have global presence and are very much customer oriented. Server monitoring is required to ensure that all their clients are able to conduct business activities with ease and accuracy and there is no congestion or huge volume of traffic on any network.

Many people think that monitoring server is the only simple way to prevent issues that would cause server to crash but that is not the only solution to secure server. Another important aspect of these monitoring services is their ability to detect under performing server and detect cause. For example dust in exhaust fan, buggy reboot etc can lead to server crash . Due to any reason, if server slows down your customer also slows down and you are left with no option. So you should always have preventive and corrective measures in place round the clock to manage smooth functioning of server.

So ask about the reliability of the server before entering into a contract with the provider. Citing server failure as a reason to change providers may be require you to give several months notice and a possible incur transfer fee for the assessment of the domain.

The availability should be at least 80 percent of the daily average. Some providers even offer compensation in the form of credits in case of server failures. Server outages due to external problems (earthquakes, war, and weather damage) are usually excluded. Dedicated and colocation services are available from a variety of reliable providers like Peer 1 hosting.

Support of a Reseller
Should there still be problems with the server, a technically adept and easily accessible support is virtually irreplaceable. With this new service, opportunities vary with the respective sellers. There are service centers, technical support, retrievable manuals, FAQ’s, email support and telephone hotlines.

It is often pointed out, in case of failure, one should, first check the FAQ’s (Frequently Asked Questions read) or download the retrievable manuals. If this still does not help identify and solve your problem, then majority of providers either provide an email support or telephone service, with some might even go for teleconference service ( if you are indeed important client ).

Note that in selecting the supplier that telephone services have significant differences; there are free and paid hotlines. In any case, you should make sure that the toll hotline is a normal phone number and not a 0190 number. It should also provide around the clock, seven days a week service with employees of the provider within reach.

Test providers
If you have limited eligible web hosting company to suit your requirements and criteria to test the accessibility of the telephone support, numbers are at best preliminary. Here, look at it: Does the vendor quickly e-mail or telephone you with inquiries? Is the telephone support line constantly busy or fast to get through possible? Are the employees friendly and service hotline, you can offer competent help for your problem opened?

Some providers offer new customers the opportunity to test your own server. Generally, this is a trial period of 30 days, without long notice periods and with a money back guarantee if not satisfied. You should make use of such an offer, whenever you can and attempt to create a separate website with all benefits.

Hardware Availability
The availability of the hardware refers to the proper functioning hardware provided to Customer by Provider under the lease.

Service Level Agreements
Just as precisely formulated service level agreements, a hosting provider should offer the customer a reliable basis for possible claims.
If the Service Level Agreement is otherwise agreed, the monitoring of the server will be according to the report of a possible disturbance independently, required by the customer. Typically, the part of suppliers and the availability of hardware are guaranteed by at least 99 percent.
