One Is: NONE

One is NONE!

Over and Over I will repeat it for the peeps in the back. ONE IS NONE!

In the world of IT infrastructure (Storage, Networking, Compute, Security, etc) we build redundant systems to maximize our uptime. The business needs reliability and predictability when it comes to delivering a service or a product.

One of my first IT mentors always talked about Murphy. It became a meme... before memes.

Please understand that this is true. It doesn't matter what the salesperson says. If it is a system, and it relies on anything human, it will eventually fail.

• TWO Internet Connections
• Connecting to TWO switches
• Connecting to TWO firewalls
• Connecting to TWO+ Core Switches
• Providing service to TWO DNS servers
• etc etc

Please. For the love of everything holy. Consider the entire design and the different failure scenarios. "How WILL this fail?" should be one of your first questions when designing anything.

• How will this fail?
• When it fails will we get an alert?
• Can it heal itself?
• Is there a redundant twin to take its place?
• Did you do a risk assessment?
• How much will a failure cost?
• How much to the business?
• How much to the clients?

I don't know about you, but I like the idea of a self healing service. This should be the goal.

So please. Don't try to save $2k a month on circuit costs if a circuit outage costs $50k an hour.
