How do I add instances (OCI) and how to manage them?
Posted by on 05.09.2012 10:54

On the OCI (Oktawave Cloud Instances), you can create your server instance in the cloud. Select the type of operating system or application from a rich library of ready-made solutions, then specify the type of instance, based on preconfigured templates and decide what type of network connection you'll need.

You can login to the newly created instance via web interface, a VNC client with encryption, or - simply - through remote desktop or SSH.



To manage instances, on the sub-page Services select the tab OCI. It also appears by default when you click 'Services' at the top of the page.



You will see a list of already created instances. The icons on the left side of the list define the status of the instance. Green means that it is enabled and active, and red that is disabled, or that there is a technical problem.

Instances can be enabled and disabled the buttons above the list (Enable and Disable) and in the settings for each instance separately (available by clicking its name).

Instances on the list can be sorted by clicking column headings, for example so that the ones with the highest IOPS (Input / Output Operations Per Second) appear first.



To add a new instance, click the Add button above the list.



Here you can quickly add an instance by specifying its name, type and size of your hard drive. There are many different types of instances differing in performance, for example:

  • v1.standard-1.05  |  1 VCPU, 0,5 GB RAM
  • v1.standard-1.09  |  1 VCPU, 0,9 GB RAM
  • v1.standard-2.2  |  2 VCPU, 2 GB RAM
  • v1.standard-4.4  |  4 VCPU, 4 GB RAM
  • v1.standard-8.8  |  8 VCPU, 8 GB RAM
  • v1.standard-16.16  |  16 VCPU, 16 GB RAM
  • v1.highmemory-1.4  |  1 VCPU, 4 GB RAM
  • v1.highmemory-2.8  |  2 VCPU, 8 GB RAM
  • v1.highmemory-4.16  |  4 VCPU, 16 GB RAM
  • v1.highmemory-8.32  |  8 VCPU, 32 GB RAM
  • v1.highmemory-16.32  |  16 VCPU, 32 GB RAM
  • v1.highmemory-16.64  |  16 VCPU, 64 GB RAM
  • v1.highmemory-16.96  |  16 VCPU, 96 GB RAM
  • v1.highcpu-2.09  |  2 VCPU, 0,9 GB RAM
  • v1.highcpu-4.2  |  4 VCPU, 2 GB RAM
  • v1.highcpu-8.4  |  8 VCPU, 4 GB RAM
  • v1.highcpu-16.8  |  16 VCPU, 8 GB RAM

The last step is to choose a template, which is the instance configuration template.



You can choose from multiple templates covering various operating systems (MSWindows, Linux, FreeBSD), databases (MySQL and PostgreSQL), application frameworks and whole programming frameworks.

Choosing configuration templates facilitates the ability to filter by operating systems. Each template has a minimum class of machine, on which it can be installed. If you choose a template with higher requirements than the configuration of your instance, it is automatically changed to meet the minimum requirements.

To install the selected template, select it and click Add OCI instance.

More advanced settings for the newly created instance are available in Informations screen.



Let us move on to the functions relating to the existing instance. For each of them you can do a snapshot copy of the disk contents. With this function you can restore the state of the instance to the previously stored point and restore it in case of failure or problems with the configuration.



To make a copy, simply select an instance (a tick in the box to the left of the name), click the appropriate button and enter a name and description (for easy view of the saved snapshots).



The list of the saved copies can be found on the Settings page of the instance (displayed when you click the instance name in the list), in the Snapshots tab. Selected copy can be restored, edited, or deleted.



Wide possibilities of instance management are available in the instance panel that appears when you click the instance name in the list. Here you can find complete information on the parameters and configuration.



The bottom of the screen contains additional features, in most cases described in other sections of the help.



In addition to the options visible from a list of instances (Disable, Delete, Snapshot), in the panel you will find some more which are available after clicking Edit.

Our panel allows you to change the type of instance, and its capacity without interruption of service. In addition, you can add and remove hard disk drives (created in the Oktawave Volume Storage service), join the private networks (described in the Help section "How to Create a Private Network (OPN) and how to manage it?") and change the way they will be billed for using an instance.


Another feature present in the panel are Schedulers, or tools for the automatic implementation of planned actions on instances. To create a new Scheduler, enter the appropriate tab in the instance panel and click Add Scheduler.



After naming the scheduler you must determine whether it has to conduct a one-time action or cyclical, and when it is to be carried out for the first time. If you decide to cyclical actions, you must still select in how many days / weeks they will be performed.



Then, in the fields you choose what action is to be carried out. You can choose from several options, including changing machine class, cloning, enabling, disabling or creating snapshots. Depending on the action selected below, a window with its specific settings will be displayed. Additional information on the uses of schedulers can be found in "What is an autoscaler and what are the consequences of its enabling?“

When you finish creating the scheduler, click Apply.
