Neon gets the MIT licensing

May 30, 2017, 4:15 p.m.

The Neon library, which will be new base of CoreCluster is now shared under MIT license. It is still in experimental phase, however you can find now some of its parts are ready for tests.

Since end of 2017 cloudover.io develops new base for CoreCluster cloud. Main idea is to change existing, centralized architecture with management node with single database to distributed system, based on blockchain, P2P and X509.

Neon is the library joining main concepts of ORM, Event Driven Development, distributed computing and cryptography. In very nutshell you can also call it a semi-blockchain protocol with additions. Stable version of Neon will guarantee data synchronization across whole cluster, without centralized server.

Each node in cluster will handle its own, most actual copy of database. All updates, changes and modifications of any objects in database are authorized by cryptographic tools, provided by GPG and OpenSSL libraries. So, as far as there is no central point, there is still very strong accent on security. Only node owning the database object's private key can update its state.

Moreover, Neon API grants some mechanisms to manage this privileges, by authorizing new keys to objects. All this features are based on well-known libraries.

Neon is written in C++, so its main API is available now only for this language. However additional language bindings will be available soon.

CoreCluster 17.04 update #2

May 2, 2017, 7:38 a.m.

Updates for CoreCluster, CoreTalk and ThunderScript were released yesterday. Major changes are:

  • New functionality of CoreCluster - the dynamic proxy. Users could make HTTP redirection to particular leases attached to virtual machines. Once redirection is done, it is possible to access any HTTP service at your virtual machine from outside network. This should be especially useful for installations without public IP pools.
  • Updated ThunderScript and TS repositories. Check new version at cloudover.io/thunder. ThunderScript is now better integrated with CoreUI. Also script repositories are reorganised and tidied up.
  • Updated CoreTalk extension - now it automatically adds new line at the end of script. In some distributions it causes problems in CloudInit parsers.
  • Fixed some bugs related to quotas and networking

Updating

Before updating bacup your database and resources. After updating packages, migrate your database (new columns were added to Lease tables and some removed from VM table):

sudo cc-admin migrate

In case of migration conflicts, use magemigrations with --merge option.

After database migration, stop all agents:

sudo service corecluster stop

restart uwsgi and nginx:

sudo service uwsgi restart
sudo service nginx restart

and start again corecluster:

sudo service corecluster start

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.
