This page contains the advantages of WAN and Disadvantages of WAN. It mentions the advantages or disadvantages of the WAN and the disadvantages or defects of the WAN. WAN denotes a Wide Area Network.
What is Wide Area Network?
A Wide Area Network (WAN) is a computer network that connects computers within a large geographical area comprising a region, a country, a continent or even the whole world.
Wide area networks, generally called WANs, are mostly public, leased or privately-owned networks. They provide a useful way of sharing resources between the end-users such as the long-distance transmission of data, voice, image, and information over large geographical areas. The best example of a Wide Area Network is the Internet which connects many smaller LANs and MANs through Internet service providers.
Advantages of WAN
If your company has branches in multiple locations, a network-wide network is a good choice that can be tailored to increase productivity and increase internal communication. Here are some of the most important business ventures to create a WAN business:
- Centralizes IT infrastructure — Many consider the WAN advantages at the top. A WAN eliminates the need to purchase email or file servers for all sites. To switch locations, you only need to set up one of your office file offices. WAN setup is also easy to manage the server, because you do not have to support, redo, host, or protect multiple systems. In addition, the WAN setup provides the key business scale by providing centralized access to all IT companies’ access.
- Boosts your privacy — Setting up a WAN allows you to share sensitive information anywhere you do not need to send data over the Internet. Have your WAN encrypt your data before sending it to add an extra layer of protection to the private data that you can transfer. With so many hackers out there simply dying to steal company information, a business needs all the protection it can get through network access.
- Increases bandwidth — WANS often uses cable systems instead of broadband networks as the backbone of their networks. Using tape systems offers many pluses for a company, including faster delivery of your broadband connection. WANS also offers unlimited data transfers each month, so you can use these links as often as you like without any cost increases. Improving communication not only increases performance but also increases performance.
- Eliminates Need for ISDN — WAN can cut costs by eliminating the need to hire multiple ISDN carriers for telephony. Instead, you can bring your own WAN to carry them. If your WAN provider “monitors audio,” you may not see audio output better. You will also benefit from a much cheaper call rate when compared to telephones that use ISDN circuits. Some companies use electrical connections. They have inbound calls over ISDN and external calls over the WAN. This method will not only save you money, but it will also reduce your bill.
- Guaranteed uptime — Many WAN providers offer business support. That means you get a monthly, monthly, or yearly bonus for a portion of your SLA. They can also give you a standing clock. Guaranteed uptime is a big plus no matter what your business. Please meet him. No company can order at any time in the market today due to the tight demand of regular customers.
- Cuts costs, increase profits — In addition to eliminating the need for ISDN, WAN can help you cut costs and increase profits in a number of other ways. For example, WANS eliminates or reduces the amount of aggregation from different entities in one place. Your business team in the United States can collaborate well with your production team in Germany using video conferencing and email. Saving on the cost of traveling alone can make investing in WAN an option for you.
- Covers large geographical area: Wide area network covers a large geographical area of more than 1000km. If your office is in different cities or countries then you can connect your office branches through Wide Area Network.
- Get updated files and data: Wide Area Networks provide you the facility of getting updated files and data from the server. If a server is updated with new data then all connecting devices receive that updated data within seconds.
- Sharing of software and resources: Like LANs, we can share software applications and other resources with other users on the internet.
- High bandwidth: WANs cover a large geographical area of more than 1000km. therefore WANs have high bandwidth compared to LANs and MANs.
WANS also has some important advantages in terms of performance. In addition to providing support for a variety of applications and multiple terminals, WAN allows companies to broaden their connectivity by connecting sites and supporting interconnections. by using gates, bridges, and routers. In addition, through network management and monitoring of implementation and performance, WANS ensures maximum reliability and reliability.
Disadvantages of WAN:
While WANS offers many advantages, they have their own inequalities. As with any technology, you need to be aware of these pitfalls to decide about WANS. The three most important ones are setting high costs, safety concerns, and marital issues.
- High configuration process – WANs are more complex and difficult, so they are cheaper to set up. Clearly, the bigger the WAN, the more worth it is set up. One reason for setting a high value is the need to connect remote locations. However, by using public networks, you can create WANs using only software (SD-WAN), which reduces setup costs. Keep in mind that the purchase price/performance of WANs is better now than a decade or so ago.
- Security breaches -WANs open the way for certain types of internal security breaches, such as unauthorized use, data theft, and damage to data. While many companies have some security features in place when it comes to affiliates, they often use the security of their databases to manage and manage the data sent to the places. These strategies reduce administrative costs but limit the company’s ability to directly infringe on the security of their facilities. Some companies also offer fast turnaround times and faster access to SSL traffic without the need for better security and the introduction of new administrations.
- Issues of Maintenance – Managing a WAN is difficult, there is no doubt about it. Ensuring that your data center is up and running 24/7 is the greatest care of all. Data center managers should be able to identify failures before they occur and minimize data downtime as much as possible, regardless of the reason. Downtime costs more, in fact, a study by infonetics Research estimates that the medium and large markets in North America lose as much as $ 100 million annually to the IT and communications technology downtime.
- Needs firewall and antivirus software: As it faces security issue, therefore it is a basic need of WANs to use firewalls and antivirus software to protect data transfer on the internet which can be accessed and changed by hackers. Also, some people can inject a virus into the computers so antivirus software is also needed to install.
