Are you confused by the differences between public and private cloud?
Well, in this VS episode, we're going to take a look
at the differences between these two very important technology sectors.
I'm Anthony Sequeira with ITProTV, and welcome to this VS episode.
Now, wait a minute, let's back up a step here.
Before we delve into the differences between public and private cloud,
let's just remind ourselves, what does it mean to be cloud?
These days, it seems like everyone wants to append or prepend
the word cloud to their technology so they'll garner more sales.
Because we all know the cloud is hot and new and exciting.
Well, what it really means to be cloud,
according to the National Institute of Standards and Technology,
is to meet five different criteria.
You should be engaging in resource pooling
in order to take advantage of all that great hardware that you have.
You should be able to make resources available on demand for your users.
There should be broad network access to the data or the solution,
It should be able to dynamically scale up
or down, or out, or in as demand dictates.
So if we're having a lot of access one weekend to our solution,
it should be able to dynamically scale to meet those access demands,
and then shrink when no longer required.
And then finally, we want to make sure that the cloud service is closely measured.
And that's because we can turn around
and be billed based on just what we used,
or, as we'll talk about in the case of private cloud,
you might want to do a chargeback to a department
inside of your enterprise that's using a lot of cloud.
So now that we understand just what makes cloud cloud
let's zero in on these different deployment models that we have.
The most popular, the one we think of immediately is public cloud typically.
This is where we are going to leverage a cloud provider
like Amazon Web Services from Amazon,
or the Azure service from Microsoft.
And we're going to have them take care of all of the provisioning
and all of the engineering of the cloud itself.
And then we will make our services available in that public cloud.
Now, if we do not want that third party involved,
we can really follow the blueprint to success
that these cloud vendors have had.
And we can implement all of this cloud technology in our own data center.
So we will be in charge of everything involving the cloud,
and we will not rely on a third party.
Now, it's interesting because most folks would think
that the most popular deployment model would have to be public.
I mean, look at the success of AWS, and Azure,
and IBM, and Google, and Alibaba.
I mean, it's got to be public cloud that's the most popular.
But what's interesting is, the most popular deployment model
is actually a blend of the two.
That's the hybrid deployment model. And that is hugely popular.
Here's why.
There's lots of things that we can't do on our own.
So, we'll go ahead and rely on a public cloud for those things.
But for those cloud technologies that we can do in house,
we love to do those in house.
So a hybrid utilization of both public and private cloud
is what we see again and again in enterprises today.
As I record this, I'm at our beautiful IT Pro TV headquarters
here in Gainesville, Florida.
And we are hybrid cloud shop
relying on AWS for some things, Azure for some things,
and our own private data center utilizing cloud tech for yet other things.
Now, if we wanted to give a startup example here,
we could use this great idea for a company that I have
and it's CATPRO.TV.
Because the internet just doesn't have enough cat videos and photographs.
So cat pro TV is a new and exciting startup.
And sure enough, there are aspects of CATPRO.TV
that my IT department and I we just cannot figure out
how we're going to be able to afford.
For instance, the fast delivery of cat videos all over the world,
not to mention our great CATPRO.TV T-shirts.
That's tough to say.
So the aspects of the CATPRO.TV
site and solution that we can't handle ourselves,
we've decided to have AWS help us with.
But many of the processes of our great CATPRO.TV company
can be done in our own private cloud.
A great example of that is the initial improvements
of the audio and video of these videos and photographs.
That's done in our own private cloud
with AWS helping us with that global distribution.
Now, just as there are a variety of technologies
that we could use to build our own private cloud,
we could be relying on Cisco and VMware, and NetApp.
We could be relying on all these different technologies
to help build the private cloud in our organization.
Keep in mind, there's options when it comes to public cloud.
We all know about AWS being the market leader.
But we know that Microsoft isn't all that far behind.
In fact, interestingly, Microsoft beats AWS now in revenue.
But there are options out there.
And I'll tell you this,
if you use IT Pro TV training to learn something like AWS
well, trust me, learning Azure and Google Cloud Platform,
it's so much easier.
Once you know one public cloud,
it's really easy to learn the others.
So is there any one solution,
one deployment model that's best?
No, there really isn't.
There are subtle and not so subtle differences between them.
For example,
if you need 100% full control over your solution,
well, public cloud is not for you.
You're going to lean more towards private cloud
where you can be in control of all of the technology.
Even though you may be spending a ton of money with AWS.
It's not like you can show up at the data center
in your local geography and say,
I want a tour, and I want to see my server,
and I want this, and I want that.
They won't even let you in.
So the complete control can be a big factor,
as well as your initial capital expenditures.
Many of us like here at CATPRO.TV,
I don't have the money to buy all of the infrastructure
that would be needed for my private cloud.
So I might start in the public cloud,
and then slowly migrate to more of a private cloud approach.
As a matter of fact,
that is exactly the path of companies like Netflix,
and Dropbox, and many of these other giants.
They started out almost all public,
and now they're almost all private.
We can't forget about the hybrid option too
for when we want to experience the best of both worlds.
