Abstract
The article describes the Institute of Nuclear Physics’ (INP) Astana branch - private establishments “Nazarbayev University Library and IT services” (PE NULITS) cloud and its integration with the distributed cloud infrastructure consisting of the Laboratory of Information Technologies of the Joint Institute for Nuclear Research (JINR) cloud as well as clouds of some JINR Member State organizations. It explains a motivation of that work, an approach it is based on, working plan of the integration.
Highlights
In order to store and process data from the installation, to simplify access to application software, to use Joint Institute for Nuclear Research (JINR)’s [3] software and experiments data it was decided to create a cloud infrastructure of Institute of Nuclear Physics’ (INP)’s Astana branch - private establishments (PE) “Nazarbayev University Library and IT services” (NULITS)” and integrate it with distributed cloud infrastructure consisting of the JINR cloud as well as clouds of some JINR Member State organizations

A complete procedure for cloud integration into described above DIRAC-based distributed information and computing environment (DICE) consists of the followings steps: 1. deploy a local private cloud at certain organization; 2. secure with SSL certificate a corresponding port of cloud service for communication with DIRAC via cloud native API; 3. allow incoming external connections from DIRAC services deployed at the JINR cloud on that port; 4. create a cloud user and set him some quota on resources; 5. contact the JINR cloud team and specify a cloud endpoint as well as user credentials
Summary
The INP’s Astana branch - PE “NULITS” cloud service is based on an open-source Infrastructure-as-a-Service platform called OpenNebula [4]. Third FN (fr1-cl3.nu.edu.kz) is a mirror of the main FN for testing cloud-to-cloud integration and future clustering with main front-end node (not used at this moment). As it was already mentioned above the INP’s Astana branch - PE “NULITS” cloud has four CNs with the following hardware configuration: 1. Cloud servers at the INP’s Astana branch - PE “NULITS” are running Linux based OS – CentOS 7 x86_64. Apart from that all CNs have cluster space on NAS/DAS
