The Faculty of Computer Science and Engineering (FCSE) within UKIM is the largest and most prestigious faculty in the field of computer science and technologies in Macedonia, and among the largest faculties in that field in the region. The FCSE teaching staff consists of 50 professors and 30 associates. These include many “best in field” personnel, such as the most referenced scientists in Macedonia and the most influential professors in the ICT industry in the Republic of Macedonia.

    The Network Infrastructure as Code paradigm empowers network engineers to create a repository of configuration templates and automation scripts, facilitating the automated configuration, management, and monitoring of the network infrastructure and services. Moreover, applying standardised approaches to high-level network processes, utilising a common data model for network description, and employing standardised open APIs for components, can offer reusability of the implementation of automated and orchestrated network solutions. In its recent activities, the GÉANT Global Platform for Labs (GP4L) group is actively collaborating with the Polish national research and education network (NREN) PIONIER focusing on developing a generalised, reusable approach to orchestrating service provisioning. By abstracting the process to define common steps in service provisioning, the goal is to provide a collaborative blueprint that other NRENs can adopt. The modular nature of the approach allows the creation of a repository of processes, subprocesses, and elementary tasks that can be reused across the community. This article presents the concept of developing generalised reusable processes and discuss challenges and decisions while working on the PIONIER use case. Aiming for reusability and sharing lessons learned, it builds towards a community of network automation and orchestration activities.

    The need for network management is universal, no matter the size of the network. Unfortunately, monitoring is often burdensome for infrastructure teams, because despite catering to their production services, additional supporting systems need to be maintained, continuously updated, and configured. As a result of the ever-growing complexity of new network management solutions, the time required for testing a new tool is increasing, thus disincentivizing exploration of new alternatives. Network Management as a Service (NMaaS) is a software suite which allows teams to centrally manage multiple remote infrastructures through effortless, fast deployment and configuration of network management applications as well as supporting tools. Using the GitOps approach, all application configuration is versioned and automatically synced to running instances, allowing easy migration from existing installations, as well as roll-back of recent configuration changes. In this demonstration we outline the NMaaS architecture, discuss possible use-cases, and showcase the application deployment process together with the steps required for extending the existing application catalog.
