Welcome again to our five-part podcast particular that seeks to demystify the web.
Our final episode centered on knowledge facilities, however we didn’t get into what occurs on the rows and rows of servers you’ll discover in these services.
So at the moment we’re explaining the cloud.
What’s the Cloud?
You could have heard a well-liked saying: There isn’t a cloud, solely different individuals’s computer systems. I would additionally add: different individuals’s wires connecting these computer systems.
This maxim is completely true. Though, as you’ll be able to think about, it is an oversimplification.
What it is getting at that is correct is that many people have a imaginative and prescient of the cloud that it’s simply there—one thing we don’t want to consider when it comes to its bodily presence and site. Each time I see a diagram of a community setup that features a cloud, I word that the cloud half is simply what we’re assuming or taking as a right on this explicit view.
The way in which we may body the query “What’s the cloud” is to ask one thing deeper. Like, “The place is my knowledge saved? And why? The place do my functions come from?”
In fact, the reply to those questions is certainly, “on another person’s computer systems.”
Let’s begin with one other elementary query. Why does it make sense to retailer my knowledge, run my functions, or do anything “as a service” some place else?
There are lots of potential solutions. However most significantly, there are clear economies of scale to housing many computer systems in the identical services the place they’ll share safety, energy, cooling, and many others. Whereas this sounds mighty environment friendly, you have to have the ability to get to those computer systems from wherever you and your gadget are.
To clarify the way it works, Senior Analysis Supervisor Patrick Christian joins me to speak cloud. We clarify what it means to get one thing “as-a-service,” hyperscalers, CDNs, and the way corporations get to the cloud.
Take all of it in earlier than our grand finale subsequent week, once we ship our closing explainer on vast space networks.
