And welcome back into this video we will be discussing about the setu tendency I attribute now when
we launch an instant within the VBC, there are certain specific tendency attribute which can be associated
with those two instances.
So there are three attributes which are available.
One is share.
Second is dedicated instance and second is dedicated to.
So let me quickly show you before we actually begin and look into each one of them.
So I'm in my idalis management control.
I go to easy to do and I select launch instant.
Let me quickly give the data that micro and within this configuration screen.
Within the tendency, if you will see a year, they will be treated sincerely with one is.
Second is dedicated, which is also the first dedicated instance.
And third is dedicated, Horst, which is basically the third option.
These are the three tenancy options which are available.
And for the example, we should understand the difference between each one of them and when you should
be using either one of them.
Now, this tendency is pretty straightforward and easy to understand.
So basically, whatever you see two instance that you launch.
So let's assume that there are three easy two instances where you're on top of a virtualization layer.
So whatever you see, two instances that you will be launching, they will be launched on this shared
hardware.
So if this is one hardware within this hardware, there are multiple easy two instances and it might
be happening that this instance belongs to you.
The second easy to instantly belong to some other established customer.
And third is to insist again, it belongs to a different customer.
So this is what is called a shared tenancy.
Now, one of the issues in this kind of approach is that let's assume that there is a second established
customer which is really abusing a lot of things.
So if he's abusing the network, the chances are that since all of the instances are under the common
hardware in your instance will also get affected.
So there is always a little risk which is involved within the shared tenancy.
Now, the second is the dedicated instance.
Now, within dedicated instances, whatever AC2 instance, that you run the run on the hardware, which
is dedicated to a single customer, which is you.
So it might happen that there can be multiple AC2 instances which will be running on a common hardware.
But all of the C two instances which will be running these two instances will belong to your W.S. So
it might not be like the first instance belongs to you.
The second is two instance belong to someone, the customer.
All of them belongs to your AWG resources only.
Now of one of the problems with this kind of approach or data is the dedicated host is was released.
Is that if you basically if you stop and start DC two instance, it is not necessarily that it will
be started on the same hardware.
It might be started on entirely different hardware, which again would be dedicated to you.
But it is possible that when you start and stop the instance, it might not start on the same hardware
and many times specifically doing the perpetual licenses which are directly tied to the hardware.
So there are certain licenses related to Oracle, Microsoft, which are directly tied to the hardware
store for that.
What customers need is that even when you start, even when you stop the you to instance, it should
be launched on the same hardware only because there are certain licenses which are directly tied to
the hardware and you cannot really change the hardware like after stopping and starting of the hardware
guessing.
It's really a big challenge and this is the reason why a dedicated host were launched.
Now, another example or one of the use cases of dedicated horse is that even if you stop and start
the instance, they will be launched under the same hardware box.
Now, the second important point is that a dedicated horse is a physical server, which basically allows
you to have much more granular control at the basketball court or even by the based licenses.
Again, as we discussed, like Windows, you have Oracle, you have Susie and various others now within
the institution.
So let me just click on cancer.
So within the instances you're a you will see you have a dedicated horse where you need to allocate
a horse to water so you can allocate a horse so this horse can be depending upon your requirement.
You do not really have to do micro and all of those things.
And this is like a physical server and you can control like how many instances that needs to be launched
and various others when it comes to the dedicated horse.
So this isn't about today's video.
We will not be doing practical related to how exactly dedicated horse works.
It is quite expensive, I would say, whenever a requirement comes with any other.
Organization, you are free to try that out there, so this isn't about to dissuade you, I hope this
has been informative for you and I look forward to see you in the next video.
