What is Load Balance?

Load Balance

The article authors wrote an article that discusses the basics of load balancing. Load balancing is a technique to distribute the traffic load on two or more lines in a balanced connections, so that traffic can run optimally. Maximize throughput, minimize response time to avoid overload on one connection line.


Some of the reasons a person in using Load Balancing is as follows:

1. Redundancy

For example, if a website we're running a balanced several servers and then one of the servers has a problem, then we still have another server and the access to the web we become uninhibited and web visitors we did not realize that one of our servers are experiencing problems or disturbances or during maintenance.

2. Response Time

If using Load Balancing, benefits are to increase the speed in accessing our website. With two or more servers to share the load of web traffic, it will be faster because it does not rely on just one server only.

Perhaps of most people assume that this will increase the Load Balance bandwidth. However, Load balance will not add substantial bandwidth we have, but only the Load Balance only served to divide the traffic from both the bandwidth that can be used in a balanced way.

Here is a shortage of software and hardware and skelebihan Load Balance:

+> Software

1. Lack of Software Load Balance

*) Most applications can not handle large sites or complex networks.
*) Application package that will support larger systems require more hardware number.

2. Excess Software Load Balance

*) Cheaper
*) Some software applications have many configuration options that can be tailored to our needs, respectively.

+> Hardware

1. Lack Hardware Load Balance

*) The cost required to purchase hardware is more expensive than to buy Software Load Balance.

2. Excess Hardware Load Balance

*) The process traffic at the network level is nominally more efficient than lunyaknya devices.
*) Can be run on multiple platforms or OS.

Overall, the advantages and disadvantages of Load Balance is as follows:

+> Shortage

*) If you are using load balancing, we will require additional costs, because we need two or more servers.
*) If the central server problem, then all virtual systems that are inside can not be used.
*) All data will be stored in a single server. so if there is someone who can penetrate into our virtual servers by collecting information from the host server, then it could be people who are not responsible for it will hang.

+> Advantages

*) Cheaper.
*) As the entrances to the services already available
*) Speed ​​up access to services, because it may lead the service request to the server who chose a quicker response.
*) Minimize when one server is down and provide services at any time.
*) To divide the work evenly among the main service servers.
