Launching and managing instances

Launching instances

  1. Log in to heiCLOUD.
  2. Under Project → Compute, click on Instances. You will see an overview of your (existing) instances.
  3. In the top right, click on the Launch Instance button. A new window will open with the Details tab. Enter a name for the instance.
  4. Under Source → Select Boot Source, select Image. You will see a list of images. Images can be selected by clicking on the "+" button.
     
    Linux und Windows server 2012:
    Select the desired image for the instance.

    Only Windows server 2016 and newer:
    Select the desired Windows server image (e.g. WS2016 heiCLOUD) for the instance. Under Create New Volume, click on Yes and enter a size for the new image. The minimum size is 65 GB. Leave the Device Name vda unchanged. This way, a HDD-Normal type persistent storage volume is automatically created.

    (Optional) Own volume:
    Changing the type (e.g. SSD) of the root drive is only possible if you create a volume beforehand.  You can find instructions on how to create a volume to use as the root drive under Mount own volume as root drive for instances.In this case, please select Boot source: Volume and specify the volume previously created.

  5. Under Flavor, select a preconfigured option for allocating resources to the instance (e.g. m1.medium).
  6. Click on the Access & Security tab. In the dropdown menu Key Pair, select the SSH key you created. In the Security Group check list, you can select one or several security groups (contain firewall rules) in which the instance is to be located (e.g. default).
  7. Click on the Network tab. Here, click on the "+" symbol next to a network from the available networks to assign the instance to it.
  8. Click on Start in the bottom right to start the instance.
  9. You will see an overview of your (existing) instances.
  10. To assign a public IP address to your newly created instance, click on the arrow button to the right in its row and select the first option, Associate Floating IP. A new window will open.
  11. Next to the IP address box, click on the "+" button. A new window will open. The Pool field must say "heiCLOUDExternal". Click on the Assign IP button. The previous window will appear again. Click on Associate to complete the process.

Please note:

  • The use of floating IPs is included and does not incur additional costs as long as these are associated with an instance. We reserve the right to charge for floating IPs that have been reserved (taken from the "heiCLOUDExternal" Pool) but not associated with an instance. Floating IPs that are associated with an instance that has been switched off or paused are not affected by this (i.e. no costs are incurred).
  • On-Demand instances incur costs as long as they are active and consume resources. To shut them down, either do so on the operating system level (Shut Off Instance) or suspend them (Suspend Instance). On demand instances that are only paused (Pause Instance) will continue to incur costs, since an image of the instance's working memory remains in the working memory of the hypervisor.

Releasing floating IPs

Floating IPs that are no longer associated with an instance must be returned to the pool of reservable addresses to stop them incurring any costs. To do so, please proceed as follows:

  1. Log in to heiCLOUD.
  2. Under Project → Compute → Access & Security, click on the Floating IPs tab. Here you will find a list of all your reserved floating IPs and the instances they may be associated with.
  3. Choose the addresses you wish to release: select them by clicking on the box of the IP. Once you have selected all addresses you wish to release, click on the button to the right Release Floating IPs. A new window with a confirmation dialog will open.
  4. Confirm the release of the IP(s) by clicking Release Floating IPs.

Please also note the information displayed in the confirmation dialog. In particular, a released floating IP returns to the pool of all available floating IPs and as such may be reserved and used by another project/user at any point.

Changing the instance size

Changing the instance size, i.e. changing to a  larger (or smaller) flavor, is also possible for running instances. Please note that the instance will be temporarily stopped in the process. To change the instance size, please proceed as follows:

  1. Log in to heiCLOUD.
  2. Under Project → Compute, click on Instances. You will see an overview of your existing instances.
  3. In the row of the relevant instance in the Actions column, click on the arrow. A new dropdown menu will open.
  4. Select Resize Instance. A new menu will open.
  5. At the top under Old Flavor, you will see the current flavor/instance type.
  6. Under New Flavor you can select the new flavor/instance type. To the right you will see the details of the selected flavor, as well as whether your current quota allows an increase (green or yellow) or whether this would exceed your quota (red).
    Changing to a smaller flavor (as long as one exists) is, of course, always possible.
  7. Should you require a higher quota, please contact the IT support.

The size of the root drive or the volume that may be attached is not altered by a change in instance type.
