It might be a bit harsh but still, if the production is critical and you expect it to work at all times you can't be surprised when shit happens if you don't have a good and tested plan. Moving everything to the cloud does not necessarily solve this issue. What if "something" happens to the cloud provider? What if someone hacks your prod system? What if you accidentally delete your data?
You still need a backup, you still need a distaster recovery plan, you still need some sort of HA solution and you still need qualified personnel. Personally I would not trust that my cloud vendor actually does this for me.
I don't really have a lot against the cloud, I have actually set up and used Office 365 for a small/medium business. But I still have local copies of that businesses data and a local Exchange server in case "something" happens.
In an attempt to save some money for my business I bought several WAP4410N's in my office to provide wireless networking. They worked great, the setup was easy, they had good range and nice functionality, they were even quite cheap.
So, based on my good experiences with the AP's, I decided to use them in one of our other offices. I bought three of them and configured them like the first ones I bought. None of them worked..... They crashed at random (but at least a couple of times each day), multiple SSID's did work, RADIUS failed. After some research I realized that the sticker underneath the AP's said "V2", the first ones I bought said "V1". It turns out that Cisco had done "something" to the hardware and called it version 2.
Contacting Cisco was meaningless, the only answer I got was "Yes, we know it does not work, you should have bought something more expensive from us". Hopefully Belkin has a bit more respect for its customers.
