First release of Occopus cloud orchestrator

11 April 2016 - 10:37am

SZTAKI is happy to announce the first official release of Occopus. Occopus is a framework that provides automatic features for configuring and orchestrating distributed applications (so called virtual infrastructures) on single or multi cloud systems. Occopus can be used by application developers and application controllers to manage virtual infrastructures at deployment time and at runtime as well as to create and provide complex virtual infrastructures to be built by one click even by novice cloud users.

The official web page can be visited at:

There are ready-to-use tutorials for Amazon and also for clouds via CloudBroker Platform.

Occopus can easily be connected (or integrated) to various applications via its REST interface.

For user support please visit the Occopus forum at where for example you can get detailed information on how to use Occopus with Amazon.

We hope you will find useful this new tool by which complex virtual infrastructures could be deployed in clouds and we are looking forward to your comments and feedbacks.

Successful cloud tutorial for beginners

17 November 2014 - 1:55pm

Last week about 30 people have visited the Laboratory of Parallel and Distributed Systems at Budapest to learn about the usage of the SZTAKI Cloud. The half day event was started with presentations that introduced the basics of the cloud systems. After the break the participant could try out the SZTAKI Cloud and learnt how to run experiments easily.

The programme and the presentations can be found here:

Photos from the event can be found at the laboratory's Facebook page.

Acknowledgement for MTA SZTAKI members at the newest release of OpenNebula

10 May 2013 - 1:56pm

We are proud to inform you, that MTA SZTAKI appears again in the acknowledgement section of the latest version of OpenNebula v4.0.

As you all may know, our collegues contribute to the OpenNebula develpoment more and more since the institute has started to work on the SZTAKI Cloud project. After the project members agreed that an OpenNebula based system is the best solution to achieve the amis of the project, they figured out that the solutions they give for the special scenarios can be useful in other situations as well, so they continually return these solutions to the OpenNebula team - and most of their source codes are part of the recent OpenNebula versions.

This time not only the MTA SZTAKI is listed on the acknowledgement section, but a few colleagues are mentioned by name: Márk Gergely (LPDS), Mihály Héder (ITAK) and Tamás Marlok (ITAK).

Dear guys, Congratulations on your achievements!

SZTAKI Cloud project has started

19 April 2013 - 1:41pm

The SZTAKI Cloud project has started today.

The project has two main goals. The first is the research on clouds as distributed computing systems and the second is to develop and to deploy an institutional cloud infrastructure based on the results of first goal that allows the significant improvement of the local IT infrastructure. This new cloud based infrastructure will be significantly more effective and more cost efficient than the former infrastructure built on traditional conceptions and individual specific servers. This new improved institutional infrastructure could even be the first milestone in a global academic paradigm shift.

A cloud can provide an automatic resource allocation mechanism for a service or for an IT system in case of the allocated resources are running out. The SZTAKI departments ILAB (Informatics Laboratory), ITAC (Internet Technologies and Applications Center), DSD (Department of Distributed Systems), and LPDS (Laboratory of Parallel and Distributed Systems) intend to exploit this capability of cloud:

  • The laboratory ILAB intends to research the possibilities of the dynamic extension of their Hadoop system.
  • The department DSD intends to research the dynamic resource extension of SZTAKI Dictionary.  
  • The department ITAC intends to resolve the asynchronous scale-out of their UIMA-based word processing system.
  • The department LPDS intends to adapt their gUSE/WS-PGRADE Portal (used in several European grids) to cloud and to make it scalable

Furthermore, the WS-PGRADE/gUSE Portal would be an underlying solution to establish a PaaS (Platform-as-a-Service) based platform service.  With the help of this SZTAKI platform, researchers can use flexibly scalable clusters established in the cloud to solve processor-intensive issues. The access to the cloud will be supported by the ITAC framework that is successfully able to establish VOs (Virtual Organizations).

SZTAKI Cloud tutorial

19 April 2013 - 1:28pm

A very successful SZTAKI Cloud tutorial was held at MTA SZTAKI on 17 April 2013. As a result of the new beta release of the SZTAKI Cloud infrastructure the developers organised a tutorial to introduce the SZTAKI Cloud features to future users.

The half day tutorial included presentations about the project background and examples of usage in several laboratories in MTA SZTAKI. The audience could learn more about how to gain rights to be able to use the cloud system and also learned the basics of the usage from two points of view: as a user and as an administrator.
