Chapter II: 2.3 Create a VM Instance
This document describe how to create Virtual Machine. Virtual Machine (VM) is a virtual version of a physical computer. Virtual machine software can run programs and operating systems, store data, connect to networks, and do other computing functions.
2.3.1 Prerequisites to Create Instance
Before creating an instance/VM, you need to create a Virtual Private Cloud (VPC) network in Create VPC Network.
2.3.2 Create Instance from public image
Public Image is provided by Cloudeka by default all customers have access to this image and can use it to create instances. The first step in creating a VM instance is to click the Instance menu.

- Click the Create Instance button
Image 2.2 Instance Page - Create Instance
- The Create Instance page will appear. Select Operating System. Then fill in the column Select Operating System by clicking the column Select Operating System, version, bit version.
Image 2.3 Create Instance Page - Select Operating System
- Select a region to choose where the data center for this VM is like at the TKP (Taman Tekno Park) data center.
Image 2.4 Create Instance Page - Select Region
- Select VPC Network. If there is no VPC Network, customers can create a VPC first.

- Select Billing Type, for details regarding billing, see the Billing Page.
- PPU (Pay Per Use),
- Fixed
- Trial
Image 2.6 Create Instance Page - Select Billing Type
- Select Choose a plan to determine the type of your VM machine.
- General, VM size provides a balanced CPU to memory ratio.
- Compute Optimized, delivers the highest performance CPU on Compute Engine and is optimized for compute intensive workloads.
- Shared, this provides a cost-effective method for running small applications that are not resource intensive.
- Memory Optimized, provides high memory to CPU ratio, optimized for memory-intensive workloads.

- Select Storage type for root disk.
- Standard Volume SSD with 750 - 2500 IOPS,
- Premium Volume SSD with 2250 - 4500 IOPS.
Image 2.9 Create Instance Page - Storage Type
- In the Instance Root disk field, enter or select a size to specify the disk size of your OS. Root disk size minimum 20GB, can not be below 20GB.

- Authentication
There are two authentication methods, this authentication is used to login to your virtual machine.
- SSH Keys, more secure than standard password. You must create SSH Keys first before you can use this method
- Choose SSH Keys for the authentication method, then click New SSH Key.
Image 2.15 Create Instance Page - Authentication
- Paste the Public key that you generated before, type the name for your key, then click Add SSH key
Image 2.16 Create Instance Page - SSH Key
- Checklist the checkbox of the key that you just added.
Image 2.17 Create Instance Page - Checklist SSH Key
- Password, use the standard password for the authentication method.
Image 2.18 Create Instance Page - Password
- In Instance Name, type your VM name, this instance name is also your VM hostname. Instance Name also can’t contain special characters, put a check mark because you have agreed to Terms of Service then click Create Instance.

2.3.3 Create Instance from custom image
Custom images are available only to your Cloud project, you need to import your custom images to Cloudeka in Custom Image. Then, use the custom image to create an instance.
- In the Instance page, click Create Instance button
