Configure Oracle Cloud Scaling
Create the necessary components in Oracle Cloud that are required for cloud scaling and then add your Credential to NavOps before creating a cloud environment.
- Create an Oracle Cloud User Account
  Create an Oracle Cloud user account so that you can later create a cloud credential in NavOps.
- Generating an SSH Public for the Oracle Cloud User
  Use OpenSSL to create a private and public key in a PEM format for the previously created Oracle Cloud user.
- Obtain the Compartment Identifier
  Obtain the Oracle Cloud identifier of the root compartment so that you can later create a cloud credential in NavOps.
- Obtain the Tenancy Identifier
  Obtain the Oracle Cloud identifier of the tenancy so that you can later create a cloud credential in NavOps.
- Add an Oracle Cloud Credential
  Add an existing Oracle Cloud account to NavOps so that you can create a cloud environment.
- Create a Virtual Cloud Network
  Create a Virtual Cloud Network (VCN) so that you can perform cloud scaling.
- Creating a Virtual Machine
  Create a virtual machine (VM) in Oracle Cloud.
- Install Accelerator on the VM
  Install the Accelerator on the virtual machine and configure the VM per your site's environment.
- Install PBS MoM on the VM
  Install the PBS Professional MoM on the virtual machine and configure the VM per your site's environment.
- Install Grid Engine Execd on the VM
  Install the Grid Engine Execd on the virtual machine and configure the VM per your site's environment.
- Install Slurm on the VM
  Install Slurm on the Linux virtual machine and configure the VM per your site's environment. Follow the instructions in the Slurm Quick Start Administrator Guide.
- Create an OS Image
  Create an image of the virtual machine configured per your site's requirements.
- Create an Oracle Cloud Environment
  Create an Oracle cloud environment in NavOps so that Accelerator execution nodes can be deployed in the cloud. Provide information about the cloud environment such as region, OS image, subnet ocid and tags.
- Create an Oracle Node Class
  Create an Oracle Node Class so that Accelerator execution nodes can be deployed in the cloud. A Node Class provides the infrastructure for the workload to run on. It is a template of an instance which defines benchmarked hardware. A Node Class exists in an Environment and consists of instance type, OS image, security group id, tags, SSH-keys and cloud-init script.
Configure Openstack for Cloud Scaling
Create the necessary components in OpenStack that are required for cloud scaling and then add your credential to NavOps before creating a cloud environment..
Add, Register, and Deploy a Cluster
After creating a cluster, it has to be registered by installing the NavOps CLI and agent. You can add node configurations containing custom resources and scripts and deploy the cluster.
Node Configurations
Node configurations enable you to customize a node associated with a cluster. Compared to operations performed via the cloud-init script these configurations are managed on the WLM server increasing flexibility and security. Node configurations are supported for PBS, Grid Engine and Slurm clusters.
Deploy Cloud Nodes Manually
Deploy nodes manually (without the intervention of the workload manager) for testing purposes or when your site wants to keep nodes deployed for an indeterminate amount of time.
Undeploy Cloud Nodes Manually
Undeploy cloud nodes when they are no longer needed.
Automate Cloud Scaling for Accelerator
Create rules to automatically scale-up and scale-down deployment of nodes on the cloud.
Automate Cloud Scaling for PBS Professional
Create rules to automatically scale-up and scale-down deployment of nodes on the cloud. Use node configuration to customize a node associated with a PBS cluster.
Automate Cloud Scaling for Grid Engine
Create rules to automatically scale-up and scale-down deployment of nodes on the cloud. Use node configuration to customize a node associated with a Grid Engine cluster.
Automate Cloud Scaling for Slurm
Create rules to automatically scale-up and scale-down deployment of nodes on the cloud. Use node configuration to customize a node associated with a Slurm cluster.
Generate API Keys
NavOps uses API keys to connect the NavOps server, WLM agent, head node and cloud nodes. Each cluster has a dedicated API KEY, if you would like to generate additional key please use the following instructions. The key is generated and displayed once. Make sure you save it as you won't be able to access it again. The key is generated for a specific cluster. The key is set on the deployed nodes. It is also present in the NavOps agent on the head node and the MoMs. The default expiry date of the key is one year. When the key expires, you can generate another one and replace the key manually on the head node.
Cost Center
Cost centers provide visibility of expenditure to dynamically manage cloud operations and plan ahead. Cost centers are associated with node delpoyments. The limits defined in the cost center are checked before deploying nodes. The estimated costs accrued by cost centers are displayed visually as well as in a table.
Accounting
The accounting dashboard provides a set of reports containing charts and tables tracking Burn Rate, Core Count, Node Count and Total Cost for the Cloud connector, Cloud credentials, Cloud environment, Node class and Cluster datasets. These reports can be produced for a custom date and time range or a set of preset date and time ranges.
Known Issues

Install Accelerator on the VM

Install the Accelerator on the virtual machine and configure the VM per your site's environment.

Log into the VM using the default user "opc" and the private SSH key of the user account provided during the creation of the VM. For more information see Accessing an Instance from UNIX and UNIX-Like Systems.

A startup script is provided during the creation of the cloud environment. This script (cloud-init script) is executed after a cloud node is deployed and is used to set up the system environment so that nodes deployed in the cloud can communicate with the workload manager. A service specifically designed for cloud instance initialization is cloud-init and is utilized by NavOps when booting cloud nodes, therefore it must be installed on the VM. For more information about installing cloud-init, refer to the Cloudinit Documentation.

SSH into the virtual machine using the default user "opc", the private SSH key of the user account provided during the creation of the VM and the External IP assigned to the VM.
```
ssh -i PRIVATE_KEY_PATH opc@PUBLIC_IP_ADDR
```
Where PRIVATE_KEY_PATH is the path to the file that contains the private SSH key of the user account provided during the creation of the VM and PUBLIC_IP_ADDR is the public IP address of the VM.

Figure 1. Bursting Virtual Machine
Enter the command:
```
sudo -i
```
Copy the Accelerator installation package to the VM.
Using the Accelerator Software Installation Guide, install and configure the system. Make the path same as the one on the Head Node. The scaling process uses a lot of data from the server, this make it easier to run the cloud-init and create the environment.
Configure the VM for your site's environment such as mounting file systems, connecting it to the authentication service, installing any applications, etc.
Check if cloud-init is installed. For example:
```
yum list installed | grep cloud
```
If cloud-init is not present, install it. For example:
```
yum install cloud-init
```
Submit a job and test to ensure it is working as expected.

Get the NATS packages from:

https://github.com/nats-io/natscli/releases
nats-0.0.35-amd64.deb
nats-0.0.35-amd64.rpm

Install NATS CLI. For example:
```
sudo rpm -i nats-0.0.35-amd64.rpm
```
To validate NATS installation, type nats and you should see the help text for NATS. This validates that NATS is installed and will meet our requirements.
