As we saw in the article Overview of Burstable Instances, I will demonstrate how to create a Burstable Instance today.
Open the navigation menu and click Compute. Under Compute, click Instances.
Click Create instance.
Enter a name for the instance. You can add or change the name later. The name doesn’t need to be unique because an Oracle Cloud Identifier (OCID) uniquely identifies the instance. Avoid entering confidential information.
Select the compartment to create the instance in.
In the Placement section, make the following selections:
Select the Availability domain that you want to create the instance in.
If you want to choose a capacity type or specify a fault domain, click Show advanced options. The following options are available:
Capacity type: Select one of the following.
On-demand capacity: The instance is launched on a shared host using on-demand capacity. This is the default.
Preemptible capacity: This option lets you run the instance on a shared host using preemptible capacity. The capacity is reclaimed when it’s needed elsewhere, and the instances are terminated. Choose whether to permanently delete the attached boot volume when the capacity is reclaimed, and the instance is terminated.
Capacity reservation: This option lets you count the instance against a capacity reservation. Select a capacity reservation from the list.
Dedicated host: This option lets you run the instance in isolation, so it is not running on shared infrastructure. Select a dedicated virtual machine host from the list. You can only place an instance on a dedicated virtual machine host at the time you create the instance.
Fault domain: The fault domain to use for the instance. If you do not specify the fault domain, the system selects one for you. You can edit the fault domain after you create the instance.
Click Change shape.
Select a shape that supports bursting.
Supported Shapes
- You can use the following shapes to create burstable instances:
- VM.Standard3.Flex
- VM.Standard.E3.Flex
- VM.Standard.E4.Flex
For the Number of OCPUs, choose the maximum number of OCPUs, for instance, to burst.
Select the Burstable check box.
In the Baseline utilization per OCPU list, select the baseline OCPU utilization, for instance. This value is the percentage of OCPUs that you want to use most of the time.
For the amount of memory, choose the amount of memory that you want to allocate to this instance by dragging the slider. The maximum memory you can choose depends on the number of OCPUs and the baseline that you select. The default amount of memory assigned depends on the number of OCPUs and your chosen baseline. The default memory assigned to burstable instances is not the same as the default amount of memory allocated to regular instances. Memory does not burst.
Click Select shape.
Finish creating the instance, and then click Create.
Hope this helps you!!!
