M1 class flavors are General Purpose Instances. This family provides a balance of compute, memory, and network resources, and it is a good choice for many applications.
G1 instances are intended for general-purpose GPU compute applications. Uses Use cases include machine learning, rendering, and other server-side GPU compute workloads. (see GPU-Enabled Instances for more on how to launch GPU instances.)

The private address, called a fixed-ip in OpenStack, is not publicly routable (that is, not reachable from the public internet; though see the Proxy section Making the most of a single IPv4 address section for more on this) and is used by the OpenStack application stack to provision the instance. The private address can also be used to communicate between instances without the need of routing traffic out on the internet and back again. The private addresses are assigned from a range of 10.1.0.0 - 10.2.254.254.
...
This limitation on IP address availability can be overcome, and in fact can make for a more robust and secure cloud environment in some cases. Please see the Advanced Guide - Making the most of a single IPv4 Address section for solutions to this problem.
...
As mentioned in the Accessing Instances section, connecting to an instance via IPv6 is preferred over using a Floating IP. Please see the links above to determine if you have IPv6 connectivity (Telus and University of Alberta users are known to have IPv6 connectivity). If you do have IPv6 connectivity, replace "floating_ip_address" with your instance's IPv6 address in the instructions below.
...
Open a terminal and enter:
...
Code Block $ ssh
...
-i /path/to/<key_pair_name>.pem ubuntu@<floating_ip_address>
...
Answer ‘yes’ to the following question:
...
Code Block The authenticity of host '<floating_ip_address> (<floating_ip_address>)' can't be established.
...
RSA key fingerprint is e5:de:ad:c3:be:ef:b2:ba:be:a1:ba:dc:af:ea:ce:d4.
...
Are you sure you want to continue connecting (yes/no)?

From Windows
There are plenty of applications that allow ssh access from within Windows, none of which are bundled with Windows (at this time). You are welcome to use any that fit your needs, however puTTY is a widely used and well supported suite of SSH utilities that includes key management and generation, an scp client and the ssh client itself.

Log-in to the Rapid Access Cloud dashboard at https://cloud.cybera.ca.
In the left-hand panel under “Compute”, click “Volumes”.
Click the Action drop-down button on the right-hand side and select “Manage Attachments”.
Under “Attach to Instance” select the instance the volume is be attached to, then click the blue “Attach Volume” button.
After a few moments, the volume will be attached. Take note of the “Attached to” column on the summary screen, it will list where it is attached like “/dev/sdc”.
Use a volume
Log into your instance via ssh.
Format the volume:
...
Code Block $ sudo
...
mkfs.ext4 /dev/sdc
...
| Status | ||||
|---|---|---|---|---|
|
...
Info Attached volumes will typically be assigned device names in sequential order (i.e. /dev/sdc, /dev/sdd, /dev/sde, etc.)
...
$ sudo fdisk -l
...
List all disks from within the instance with:
...
Code Block $ sudo fdisk -lInfo
/dev/sda and /dev/sdb are the system volumes that make up the instance.
...
Create a mount point for the volume:
...
Code Block $ sudo mkdir /mnt/<mount_point_name>
...
Mount the volume device to the mount point:
...
Code Block $ sudo mount /dev/sdc /mnt/<mount_point_name>
...
...
Permissions may need to be changed on the new volume, as they are initially set to root:
...
Code Block $ sudo chown ubuntu:ubuntu /mnt/<mount_point_name>
...
Backups
The Cybera Rapid Access Cloud is offered on a best-effort basis and it is the users’ responsibility to ensure appropriate backups of all their data are made. While Cybera’s record for uptime and data-loss is very good, we strongly encourage all of our users to ensure regular backups are made.
