Wide Area Network or WAN are one of the most useful business tools. For any business to run smoothly, there is a need for secure and reliable connectivity for the transfer of data on a daily basis. This flow of data is done via networks. Computer networks are basically a set up where PCs are interlinked to facilitate the conveying of information from one system to another. So, depending on the size and area of coverage of the organizations, the networks can be of 3 types- Local Area Network (LAN), Metropolitan Area Network (MAN) & Wide Area Network (WAN); where LAN caters to the smallest area, MAN covers a larger area as compared to LAN and WAN covers the largest area of all.
A Wide Area Network or WAN is basically a network of computers, that are spread across a large area geographically, that could include cities, states or even countries, by the use of direct point-to-point connection between two sites of the company. These connections are often made using leased lines by set up by telecom providers. Remote locations can be connected easily with the company headquarters by using WAN and the data that is transferred via WAN would be inaccessible for anyone who doesn’t belong to the organization, unlike general mode of communication via internet.
So, let’s take a look about the pros of the WAN:-
• Secure & Private:
As mentioned earlier, the data transfer via WAN is much more secure and private due to its direct and dedicated nature to connect the systems.
• Better network performance:
As WAN provides a direct communication system, the data that is being sent across doesn’t compete with any other general data for bandwidth availability over the internet and hence goes through without facing unnecessary lags.
• Centralized Infrastructure Management:
One of the biggest pros of WAN is that it allows for a centralized IT infrastructure management, by doing away with the requirement of purchasing emails or servers for every office. By using WAN, there is no more a need to back-up or support multiple units. All the IT resources of a company can be put in and accessed from a single point.
• Increased profits by cutting costs:
WAN also offers features that can facilitate phone calls and hence does away with the need to rent any ISDN services. Also, logically, unnecessary travel costs to bring different teams from different locations together on the same page for a project are simply not required as WAN makes the communication via video conferencing and/or phone calls just that much simpler and convenient.
• Uptime guarantee:
WAN providers offer guaranteed uptime as a part of their SLA and round the clock service to ensure that the system is never down for too long.
Now some of the cons of Wide Area Network can be noted as follows:-
• Initial high set-up cost:
This makes sense as the networking connectivity has to be quite complex and elaborate. Hence the set-up can initially be quite the pinch on the pocket.
• Security-related issues:
White the security risks from external sources are next to nothing in case of WANs, but the internal risk factors are still at play, with the chances of information theft, any malicious damage to the data files or unauthorized use. As the security measures are mostly deployed at the data centers, managing any kind of breaches at the particular location can be quite challenging.
• Maintenance-related issues:
As any kind of technology downtime directly means losses in revenue, the maintenance of the>Now, having understood the pros and cons of this power tool for businesses, one much make an informed choice and decide to use the WAN system, where clearly the pros outweigh the cons that are mostly manageable for a business of modest means. Bottom-line is that a WAN will ensure better communication internally within a big organization which translates to enhanced efficiency and a better productivity all across.
