And welcome back now into this video at a high level or if you will be discussing about the on demand
capacity solution only Video-On-Demand instances, there are chances that the new instance might not
get launched due to insufficient capacity error.
So although this is not very common, but this happens in many cases, no one of the typical solution
to go ahead and avoid this specific issue is to covid reserved instances, which gives you a capacity
reservation.
Now, one of the challenges in such cases is that if you go to reserve instance with capacity reservation,
you'll have to go with either one or a three year term.
And this is something which is not suited for a lot of organizations.
Now, in order to avoid this, it has come up with a new feature of OnDemand capacity reservation.
Now, in this specific approach, AWG will allow you to reserve the capacity for your easy to instances
in a specific availability zone for any duration.
And this is a big benefit.
So you can go ahead and create a capacity reservation any time without entering into a one year or a
three year commitment.
So this is the primary aim of OnDemand capacity, a reservation.
Now, let me quickly show you.
So from the easy to console, you can go to the capacity reservations and you can go and create a capacity
reservation.
Now, within a year, you'll have to select instanced types of multiple instance types are available.
You have to select platform.
You also have to select availability.
So this is important and you can select the tendency it can be a or dedicated instance, the quantity
of instances that are required.
And one of the important things here is the reservation detail.
So either you can go ahead and cancel the reservation once you're finished or you can also go ahead
in a specific time for which you need the capacity reservation to be in place.
Once you have done with this, you can go ahead and do agreed.
Now, one important part to remember here is that you can combine the capacity reservation with regional
reserve instance to receive a discount.
Now, do know that the regional array does not give your capacity a reservation, so the on demand capacity
reservation with array can be used together.
So let's go ahead and look into it in detail.
So four on demand capacity reservation.
As we're discussing, no commitment is required for a regional array.
One year or a three year commitment is required.
So the capacity benefit here is that the capacity is reserved in a specific availability zone for a
regional array.
You do not really get the capacity building discount for on demand capacity reservation.
You do not get a billing discount, however, for a regional order.
It does provide you a billing discount here and hence you can go ahead and combine both of them to achieve
the best of both cases.
Now, a few important things that you need to note for the on demand capacity reservation.
First one is that when the capacity reservation and does the active state are the equivalent on demand,
whether you are running the instances in the resort capacity or not, this is very important.
Even if you're not running the two instances, you will still be charged because you have made that
capacity reservation year and the charge will be based on the on demand.
Second is that if you do not use the reservation, this shows up as a new reservation within citable.
So, for example, let's say that the capacity distribution for 20 for next instances have been made
by you and you only run 15 enfilade instances in the same availability zone.
So what will happen is you will be charged for 15 active instances, as well as the five unused instances
within your capacity reservation.
So this is the high level overview about the on demand capacity reservation.
