IaaS, or Infrastructure as a Service, is the industry term for basically running your network via a service model, such as what we have all come to know as the cloud. So rather than purchase server hardware, pay someone to maintain this hardware along with the software that runs on it, keep up with warranties, and replace all of that in five years, you run some or all of the applications that you needed that hardware and software for in the cloud and pay a much smaller monthly or yearly fee as opposed to a large upfront cost.

Iaas or Infrastructure as a Service, is what it's called to run virtual systems, servers just like you have in your office, in Azure.

Think of it this way: a thief is walking down a street lined with parked cars. He stealthily attempts to open the doors of each car he walks by. If its locked, he moves on. He doesn't even leave the sidewalk to try the street side lest he expose himself to viewing by the buildings across the street. He tries the next car, and the next, and the next, until he finds an open door on a 9 year old unassuming sedan. He sits down, rifles through the glove box, under the seat, center console, floor in the back seat, and takes whatever he can carry. He even finds an extra ignition key in the glove box, but he doesn't care he has no intention of stealing the car. However he just walked away with your $90 sunglasses, your $50 Pottery Barn gift card you got for Christmas, an iPad on the floor of the back seat, and worst of all several old credit card and banking statements you left in your center console.

Seems Google has learned the old ways of Microsoft and other software companies. It was discovered that if you used the Google Chrome browser, it is loading listening software without permission, to turn on your microphone and listen in on your conversations.

Microsoft Azure has become the most effective solution for your Disaster Recovery plan that I have ever seen, especially in terms of cost to implement compared to the abilities you get. You can use Azure to back up your systems and/or replicate them in their entirety so that during an emergency, and even for testing purposes, they can be turned on in the cloud and accessed just as they were when running on your on-premise hardware.
