Hybrid Clouds¶

Step 1. Configure a Hybrid Region¶

In the Control Panel is possible to add regions of Amazon EC2, IBM SoftLayer and Microsoft Azure to be used within vOneCloud.

Each region from the different supported cloud providers have different requirements in terms of configuration:

Amazon EC2

The capacity that you attach to this region will define the maximum number and type of Virtual Machines that vOneCloud will be able to launch in the represented Amazon EC2 region. The different instance types are defined as follows:

Follow the tool tips that appear on mouse over to correctly configure the parameters.

You need the Access and Secret key to be retrieved from your AWS account. More information on Amazon EC2 support can be found here.

MS Azure

The capacity that you attach to this region will define the maximum number and type of Virtual Machines that vOneCloud will be able to launch in the represented MS Azure region. The different instance types are defined as follows:

Follow the tool tips that appear on mouse over to correctly configure the parameters.

You need the Pem Management Certificate to be retrieved from your AWS account. Follow the next steps to craft a valid certificate:

• First, the Subscription ID, that can be uploaded and retrieved from Settings -> Subscriptions
• Second, the Management Certificate file, that can be created with the following steps. We need the .pem file (for the ruby gem) and the .cer file (to upload to Azure):

## Install openssl
## CentOS
$ sudo yum install openssl
## Ubuntu
$ sudo apt-get install openssl

## Create certificate
$ openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout myPrivateKey.key -out myCert.pem
$ chmod 600 myPrivateKey.key

## Concatenate key and pem certificate
$ cat myCert.pem myPrivateKey.key > vOneCloud.pem

## Generate .cer file for Azure
$ openssl  x509 -outform der -in myCert.pem -out myCert.cer

• Third, the certificate file (.cer) has to be uploaded to Settings -> Management Certificates

Afterwards, copy the context of the .pem certificate in the clipboard and paste it in the text area of the Control Panel Pem Management Certificate field.

IBM SoftLayer

The capacity that you attach to this region will define the maximum number and type of Virtual Machines that vOneCloud will be able to launch in the represented IBM SoftLayer region. The different instance types are defined as follows:

Follow the tool tips that appear on mouse over to correctly configure the parameters.

You need your SoftLayer Username and the API Key that can be retrieved from your SoftLayer Control Panel. More information on IBM SoftLayer support can be found here.

Step 2. Restart vOneCloud services¶

Click on the “Apply Settings” button. For changes to take effect, you need to restart vOneCloud services and wait for OpenNebula state to be ON.

Step 3. Create vOneCloud hybrid resources¶

Afterwards, each region can be represented by vOneCloud hosts can be added from the vCenter View:

The hybrid approach is carried out using hybrid templates, which represents the virtual machines locally and remotely. The idea is to build a vOneCloud hybrid VM template that represents the same VM in vCenter and in the public cloud. This can be carried out using the hybrid section of the VM Template creation dialog (you can add one or more public cloud provider)

Moreover, you need to add in the Scheduling tab a proper host representing the appropriate public cloud provider. For instance, for an EC2 hybrid VM Template:

Once templates are ready, they can be consumed at VM creation time from the Cloud View:
