Oktawave Volume Storage

OVS provides a durable record of the data for instances, allowing you to manage disk volumes, regardless of which instances are using them, and assign one volume to many instances at the same time, building clusters such as SQL or High Performance Computing (HPC). OVS is a standard block device running in one of three standards that guarantee the following parameters:

  • Tier 1: up to 1000 IOPS and up to 150 MB/s of sustained transfer,
  • Tier 2: up to 20 000 IOPS and up to 500 MB/s of sustained transfer,
  • Tier 3: up to 50 000 IOPS, and 800 MB/s of sustained transfer.
  • Tier 4: up to 100 000 IOPS, and 1,2 GB/s of sustained transfer.
  • Tier 5: up to 200 000 IOPS, and 1,8 GB/s of sustained transfer.

Each OVS volume may at any time be migrated to a different class. Snapshots are performed in the context of the instance to which the volume is assigned.

Payments for the OVS volumes include the amount of space (in GB) and the number of performed IO operations.

Oktawave Private Network

Thanks to isolated internal network philosophy Oktawave allows you to easily build arbitrarily segmented network. For example, you can create a public network, in which you put web servers, internal network with databases and administrative network of sales support system. You have the guarantee of the isolation and security of each of the defined zones.

Oktawave Watch Service

OWS is an external monitoring service, which perfectly complement the existing tools, solving problems that are impossible to detect by local monitoring.

While the internal monitoring systems are primarily focused on the basic, low-level system parameters (CPU, temperature, occupancy, operation process of the system), the OWS system checks the final result of interaction of the subsystems responsible for the content and features delivered to end users.

Even when extensive failure affecting both systems and internal monitoring systems, our monitoring is still running and you can immediately tell the event the person responsible. If not used external monitoring, extensive information about the crash can reach the administrator only after some time (a phone call from a client, another department, etc). At this point, every minute counts. The faster you react to an event administrator, the sooner fail to return the system to operation.

Oktawave Watch also provides tests of full page with HAR speed of loading all the elements of the test site analysis. Thanks to HAR analysis you will see which items (such as image files, styles, scripts, external links) contributed to the opening time of the test website, and which download phases lasted the longest.

Oktawave Command Line Interface

CLI (Command Line Interface) is one of the most common way of communication of human beings with IT systems. Thanks to special syntax and set of the exact commands it is possible to control the computers, networks and cloud computing systems. We can issue these commands manually, by typing them individually in the so-called management console, or automatically, grouping them into scripts and running the whole package.

In the Oktawave cloud you can communicate with the instances using just CLI. Just download the appropriate software Oktawave CLI (download from here: https://github.com/oktawave-code/oktawave-cli), install it in the operating system and run the appropriate command from the console. Currently, this tool is available in the form of packages for the Open SUSE, CentOS, Debian and Ubuntu, as well as the source files to compile yourself.

After installing Oktawave CLI on your system, you can begin to remotely manage your instances in the cloud. To do this, move the authorization process and begin issuing commands or scripts. The standard command structure is as follows.

oktawave-cli NAMESPACE COMMAND [arguments]

We deal here with the argument NAMESPACE, determining the most common type of service to which they refer, COMMAND, which defines the action taken at the instance or container, as well as the other parameters.
