Migration to Google Cloud Platform
Replication Settings for GCP
The REPLICATION SETTINGS page helps define your target environments. And also helps define Replication Servers in the Staging Area of the target infrastructure.
-
After entering your GCP credentials in the IBM Live Migration Service user console, navigate to the Setup & Info > REPLICATION SETTINGS.

-
Next step is to define the Target infrastructures and region.
Define the Target infrastructures
To define the target infrastructure, select the GCP region which ideally serves as the target to where you want the replicated data consolidated. Set the target from the Live Migration Target dropdown menu.

After defining your target, you need to define your GCP Zone. Each GCP region has several zone options. Select the applicable zone from the dropdown menu.

Defining Your Replication Servers
After selecting your target infrastructure and regions, you need to define your Replication Servers.

Defining the Subnet
On the Replication Servers section, set the subnet of the Staging area under the Choose the subnet where Replication Servers will be launched: From the dropdown list, select the subnet you want to designate as the Staging area for the Replication Servers.

The Default subnet is the subnet that is allocated to you by GCP. The other subnets in the dropdown list are subnets automatically allocated by GCP to the region you selected.

[Optional] Define VPN usage
[Optional] On the Replication Servers section, select whether you would like to use a public or private network for sending the replicated data from the source machines to the Staging area. Check the box to the left of the Use VPN… option to use a private network.

- Allocate a dedicated bandwidth for replication;
- Use another level of encryption;
- Add another layer of security by transferring replicated data from one private IP address (Source) to another private IP address (Target).
By default, replicated data is sent from the source infrastructure to the Staging area over a public network, using the public IP of the Staging area.
The transferred data is protected in transit. Before moving data to the Staging area, it is encrypted on the source infrastructure using Advanced Encryption Standard (AES) - 256-bit encryption. Once data is delivered to the Staging area, and before the data is written to disks, it is decrypted.
Define the Proxy
Once you have checked Use VPN. option, you need to define the URL and Port of the VPN proxy server.
Enter your VPN proxy URL under Define whether to route communication from the Replication Server via a proxy: field after the https://.
Enter the port in the port field.

[Optional] Enable Network bandwidth throttling
The Network bandwidth throttling option allows you to regulate network traffic and minimize bandwidth congestion. Enable this option, if you want to control rate of data transfer sent from the source machine to the Staging area over TCP Port 1500. Once enabled, set the data transfer rate in Mbps. Uncheck the Disabled box to enable the option, then move the bar to set your throttling rate.

Saving Your settings :
Once you have set all of your settings , Click the SAVE REPLICATION SETTINGS button at the bottom of the page.
You will now be able to add machines to your project which is described in the next section.
