In the National Academy of Sciences of Ukraine, the main computing resources are concentrated in autonomous data centers of leading institutions in the form of cluster systems. At the same time, in order to gain access to computing resources, the institution is forced to apply directly to the owners of data centers and agree on their own about their use, which is quite a difficult task both organizationally and technically.
Combining stand-alone data centers into a single infrastructure with a single access point can greatly simplify the process of finding and using computing resources and improve the resource provision of research.
To do this, each date center allocates part of its resources for public use by creating an appropriate project and setting quotas for the use of resources and attaches the ENIP administrator to this project.
The Single Access Point (Cloud HUB) tracks the free resources allocated to the ENIP in separate data centers and provides a user-friendly interface for the administration of the ENIP, including the allocation and allocation of resources for research projects.
The composition and size of quotas that should allocate data centers for public use, as well as the composition of research projects and their quotas are determined by the competent commission.
Cloud HUB provides an interface for submitting requests to open projects in the ENIP and allocating quotas for resources for projects, as well as an interface for obtaining resources from the general fund within the allocated quotas. Cloud HUB, based on free resource accounting, automatically searches for data centers that have the required free resources and forwards the resource request to the found data center using its API.
