Abstract
Capacity planning of the infrastructure is a difficult task performed during the virtualization of the IT infrastructure. It is the planning of the necessary hardware to which the existing systems will be transferred, and later the future systems that will work in a virtualized environment. Infrastructure capacity planning in digitalization of educational services is a process in which the IT infrastructure is needed to meet not only the current workload but also the future workload and to follow further requirements. In case the process of planning is well performed, it could more fully support the development of emerging technologies in learning. The traditional IT infrastructure, bound by the physical limitations of the devices, does not meet the requirements for flexible changes, for quick recovery after a problem. This leads to difficult management, to weaknesses in the implementation of educational processes. Virtualization could solve most of these problems for modern IT infrastructures. It provides highly efficient and reliable operation of operating systems and applications that do not depend on the computer system.
Highlights
Capacity planning in the digitalization of educational services is a process in which the IT infrastructure is needed to meet the current workload and the future workload and compliance with future requirements
Capacity planning for the digitalization of educational services in universities [14] [15] should be done in terms of efficient use of resources to provide the IT services needed by the university users
The procedure we propose to follow when planning the capacity for digitalization of educational services in universities is as follows: first to monitor the metrics for productivity and load of the current IT infrastructure, to design the new infrastructure based on good practices, manuals from the manufacturers of the virtualization solution and in addition independent from the manufacturer own calculations
Summary
Capacity planning in the digitalization of educational services is a process in which the IT infrastructure is needed to meet the current workload and the future workload and compliance with future requirements. Capacity planning of the new infrastructure is among the most difficult and uncertain tasks performed during the virtualization of the IT infrastructure. It is the planning of the necessary hardware to which the existing systems will be transferred, and later the future systems that will work in a virtualized environment. This stage includes the selection of virtualization software between different options, selection of a storage system, design of the network topology It is based on the detailed inventory consideration for the applications used and the services offered by the servers in the current hardware. In addition to the capacity of the infrastructure components, the capacity of the IT team should be planned at this stage - on the one hand servers are consolidated and the people involved in their support will decrease, on the other hand more skilled administrators are needed to administer the additional layer in IT the infrastructure - the virtualization
