About key pairs
Key pairs are a set of mathematically generated strings, one is the private key and the other is the public key. The key pairs that are used in the Rapid Access Cloud are ssh keys generated by the OpenStack dashboard, keeping the public key to be injected as needed into new instances, and the private key is the *.pem file automatically downloaded by the browser in the steps above. If you already have a key pair suited for use, import that key by following the steps in the Advanced Guide.
Security groups are the policies that deny access to the network ports of an instance. Security groups are therefore firewalls for instances, with a set of default policies that block all access to each port from any source, including the computer you are using to access the Rapid Access Cloud dashboard. Before an instance can be accessed the appropriate ports will need to be opened and a source IP address or range of addresses will need to be configured.
You should verify that the snapshotting process has worked following completion. Check the size of the snapshot as it should be at least several hundred MB in size. Also consider test launching an instance from the snapshot in order to ensure the process concluded successfully. .
Exporting a Snapshot
If you would like to take an instance snapshot to a different cloud, or a different account within the Rapid Access Cloud, you can use the OpenStack cli tool to export the snapshot image.
- In a terminal, with the openstack cli tools installed, and the openrc file sourced, type: openstack image list
- In the list of returned images take the ID for the snapshot you have crated and run: openstack image save --file export.qemu $id # Where $id is the ID from the command above.
The above will save your image as export.qemu in the folder you ran the command. You can then upload that image to a new account or another cloud.
Users may also use the Object Storage service to back-up their data. See this document for more information.
