Virtual Compute Node – Image
A Virtual Compute Node image is an image template of your node that provides the functionality to launch new nodes instances from saved images. The image backups can be saved as a customized image with updated configurations. All saved images are billed only for the disk space used i.e. at Rs. 6.25 per GB per month.
Let’s look at a few scenarios which would require you to use this feature.
If you are a sort of user who requires virtual compute nodes only for occasional use, then you can create a disk image of your server & launch a node from it whenever you need it. Since images are billed only for the disk space used, you will save cost on the duration you don’t need an active node.
When you need to test new features but are worried that the data on your node could be compromised, you can create an image of your live node. This will provide you with a safe environment to test them out without bothering the existing node.
When you require more resources on your node you can create an image. With the same image, you can launch the same configuration node or may upgrade to a higher configuration node.
To Create an image please follow the below procedure –
Create & Manage – Images
A Virtual Compute Node Image is a template to create new instances. You can create your own images from running instances with an operating system along with the software and patches installed on them such as databases, applications, etc. The image can be used to create multiple virtual machines which are easy to setup with a predefined template.
Create an Image
Power Off Node
To save an image of a Virtual Compute Node it must be powered down.
Click on the Power Off button.
Create Image Template
Once the respective Virtual Compute Node is powered Off click on the ‘Save Image’ button under the Actions section.
Name the Image
Create a name for your Virtual Compute Node image and click on Save Image button.
A popup message will appear indicating that your image is being saved.
You can switch on your Virtual Compute Node once the node image is created.
Note: All the management operations will be disabled on this node while the image is being saved.
Manage – Images
To access the saved image click on ‘Saved Images’ on the dashboard.
To rename your existing image click on the ‘Edit Name’ button.
Assign a new name to the existing image and click on ‘Update Image’ button.
To remove an existing image click on the ‘Delete’ button.
A confirmation message will appear, click on the ‘Delete Image‘ button to confirm the deletion.
Create New Nodes from Saved Images
To create a new node from an existing image please follow the steps below –
To create a new node from the saved images go to the saved images section.
Click on the Launch Node ‘+ ‘ button next to the same image from which you want to create a node.
In the next window, you can choose a configuration available for your image.
Select a plan of your choice from a wide range of suitable options for various requirements.
- Series A – CPU Intensive Computing
- Series B – Memory Intensive Computing
- Series C – High-Performance Computing
Select the E2E Networks server series and size with respect to the amount of vCPU/RAM. At any point in the future, you can adjust your server plan using the flexible configuration options.
