We seem to bounce back and forward when it comes to implementing the best system topology.
We want it distributed for more power,
then we want it centralised for more control,
then distributed centralised systems for more controlled power.
And now cloud because it’s cheaper, easier and I can work from my bed.
So I write this post inspired by last years attack on the JANET network http://www.theregister.co.uk/2015/12/15/janet_no_longer_shares_network_information_after_ddos/
It highlighted that, the ease of a cloud base system comes at a price.
You now have one point of failure, your internet connection.
This attack saw the internet wiped out for many education institutions in the UK.
For sites which rely highly on web based systems they may have well just packed up and gone home.
No registers, no files, no email, no library system, no BBC website and most importantly no YouTube!
Domestic broadband is no better.
I recently experienced snail pace internet when checking a customer’s broadband speed. Speedtest.net returned a result of 300kb download connection.
Can you imagine that? I would say that is not broadband, but by definition it is anything that is greater than dial up (56kb)
Companies such as BT will guarantee a minimal speed of 256kb
So what can you do?
Have a back up
With a Dual WAN Router you can link multiple Broadband Lines together
It can Load Balance your traffic over the connections
And if one dies the other lives on
If a day without Internet is not an option
Then it’s something to consider
An ideal scenario is a Virgin Line, BT Line and a 4G Dongle
But if you want a smaller, simpler solution then a 4G Dongle or Mobile Router would also do the trick
In any case having a Plan B is always a good idea
