MTA Cloud provides cloud computing resources for researchers in Hungary through two sites, MTA SZTAKI and MTA Wigner Data Center. It currently has over 1,160 vCPUs and over 400 TB of storage deployed across the two sites. MTA Cloud uses an open, multi-cloud architecture and common interface and middleware. It hosts over 50 research projects and provides Infrastructure as a Service as well as Platform as a Service like Hadoop and Docker clusters through tools like Occopus and Flowbster. Significant extensions are underway to increase its computing and storage capacity to better support the Hungarian research community.

Activities of the Hungarian NGI
• Providing IaaS Cloud systems:
• MTA Cloud for the researchers of the Hungarian Academy of Sciences
• https://cloud.mta.hu
• NIIF Cloud for the Hungarian universities
• https://niif.hu/en/cloud
• Plan to create a Hungarian National Node in the European Research Data
Alliance (RDA) with the participation
• of the cloud providers of the above mentioned 2 clouds
• of some hungarian libraries
• of several academic institutes using large scientific data

MTA Cloud is an alliance of cloud
sites
The goal was to build an open, multi-cloud architecture to which other clouds
could join later. Therefore MTA Cloud is organized as an alliance of cloud
sites. Currently two sites are involved:
• MTA SZTAKI
• MTA Wigner Data Center
Alliance means:
• The user interface to register and authenticate for the users is common
• The applied cloud middleware is the same (OpenStack)
• The webpage of MTA Cloud is common
• The management of the system is a joint activity of SZTAKI and Wigner
Data Center
• The training and user support activities are common

Flowbster: workflow choreography
The goal of Flowbster is to enable
• The quick deployment of the workflow as a pipeline infrastructure in the
cloud by Occopus
• Once the pipeline infrastructure is created in the cloud it is activated and
data elements of the data set to be processed flow through the pipeline
• As the data set flows through the pipeline its data elements are processed
as defined by the Flowbster workflow

• After one year of usage there were more than 40 projects that used nearly
the whole set of computing resources
• As a result significant extension of MTA Cloud is on its way
• MTA Cloud is getting more and more popular, currently 52 projects are
hosted
Maintenance and user support of PaaS services are supported by the
Cloudifacturing EU project

… welcome use cases that
a) simulate manufacturing processes or manufacturing tools,
b) leverage factory data to learn from it, and
c) optimize manufacturing processes and/or manufacturability of goods.
The use cases need to be driven by the end user; in other words, a manufacturing company,
preferably an SME. If you are interested in our Open Call or you have questions, please contact
one of our local DIHs spread all over Europe:
For southeast and northeast Europe:
