WHY TWO INTERNET CONNECTION?

Two is one and one is none in IT Network industry

From network stand point since ten years of my experience or being directly involved in many network infrastructure, topology or designed, I found that. Having alternative solution in IT especially, system and network infrastructure in the network industry if the public internet connection goes off then the entire office will not have internet, you would trigger the owner of the company, and it is vividness that 99.9% of our job is relay on internet such as, email communication, voice communication, video communication so on.

Therefore as a network engineer my suggesting would be, alternative connection such as backup link or backbone link, which called failover or loadbalancer. It doesn’t mean that we're saving our job

but rather we are preventing from bad experience that other people have been faced.

 At least having one satellite internet connection, make sure to get dedicate connection! Because they might ask you ‘Do you want share or dedicate bandwidth 1:1 or 1:4’

I prefer dedicate due to stability of internet connection, 'ISP' internet service provider 99.9% granted  With fiber connection the price is reasonable, faster due to high bandwidth unfortunately not very stable! In network field stabilities is concern!

So now you have two internet connection means no complain at all, because you have two connection one is active another is passive or standby. My network scenario

Or design, I would use it for some main purpose such as FTP or cloud computing. Farther more

If the main link goes off it automatically turns to second internet connection beside what I have configured such as FTP or cloud computing.

Note; if your office doesn't have much critical client or project, go for single connection

Don’t forget that IF WE DON’T CARE OF OUR CLIENTS SOMEONE ELSE WILL!
