CloudOver is now dual-licensed: commercial + AGPL3

April 18, 2017, 11:51 a.m.

Last days licenses of CoreCluster, CoreNode, CoreNetowrk and CoreTalk were changed to dial licensing model: GNU AGPL3 and commercial licensing

As you might noticed, code in all our repositories was updated. All main packages are now licensed in dual licensing model: GNU Affero GPL version 3 and commercial. In our official repositories you could find now AGPL versions of whole software.

Additionally, you could use our software in commercial way, without all restrictions made by GPL and AGPL licenses. If you purchase commercial license package you could use it as the closed-source software without all restrictions made by AGPL license.

Commercial licensing terms you can find at cloudover.io/licensing

Changes in supported operating systems

In parallel we changed supported operating systems. Now the supported systems are:

  • Debian Jessie (8)
  • Ubuntu Xenial (16.04 LTS), Yakkety (16.10) and Zesty (17.04)

From this time older distributions won't be supported.

CoreCluster 17.03

March 29, 2017, 11:43 a.m.

New release of CoreCluster is out!

The latest release of CoreCluster contains several security updates - related to authentication methods and networking. It also adds some usability fixes in Administrator's panel. Now you can filter all virtual machines and images by users and/or computing nodes to easily find proper entities. Read more in the release notes of packages.

Update changes also default SHA1 algorithm to SHA512. Some issues related to using PyCore and CoreUI interfaces may be noticed by users registered in 16.12 and previous versions. Password change is recommended to fix this issues.

In our repository you should find new versions of CoreCluster, CoreNode, CoreNetwork and PyCore packages.

Introducing new Cloud Starter Kit with Raspberry PI

Feb. 20, 2017, 9:11 a.m.

We have pleasure to introduce the Cloud built on the Rasberry PI computer.

This is kit for starting adventure with cloud computing systems in very simple way, without any expensive hardware. Learn how to manage virtual infrastructure and jump into the IaaS environment.

With CoreCluster Cloud Starter Kit you will get preinstalled and preconfigured management module, based on Raspberry PI. This kit contains boot-up instruction and all tools necessary to build private computing cloud and connect your computers as computing nodes.

Neon - the P2P database and next releases of CoreCluster

Feb. 19, 2017, 7:43 a.m.

We have pleasure to introduce new roadmap of CoreCluster project.

As you could noticed, we have new repository at GitHub - the Neon. This will be a Open Source P2P database, which will be core component of next releases of CoreCluster tools.

Why not SQL or No-SQL?

Making a cluster of databases for CoreCluster backend is quite difficult task for inexperienced administrators. As in most of projects we want to simplify most of tasks and keep it powerful. Since SQL databases are great and we not question it, this generates single point of failure in your system. Even, if you make a cluster of databases - look on architectures like OpenStack or CoreCluster. In whole system, there is small point - management and the extant part of cluster.

Neon is approach to make CoreCluster into fully P2P architecture. It means, that each node in cluster will have the same privileges, the same data set and will be independent of any management. Moreover - there won't be any central point of this cloud.

We want to use cryptography and distributed databases, like Bitcoin to keep everything secure and safe. If you want read more about our ideas behind Neon, follow our blueprints at ResearchGate


Since version 16.12 CoreCluster will be released in 6 months periods with only bugfixes and small improvements. It is not applicable to the extensions, which will be developed independently.

CloudOver Google Groups

Feb. 16, 2017, 5:35 p.m.

I've just created two forums at Google Groups. First, dedicated for users you could find here:

Use it for any installation and configuration issues, also for suggesting changes.

Second forum is dedicated for development issues and any work related to extending CoreCluster and other tools. Feel free to publish here:
