The evolution of communication networks, bringing the fifth generation (5G) of mobile communications in the foreground, gives the vertical industries opportunities that were not possible until now. Flexible network and computing infrastructure management can be achieved, hence bringing more freedom to the service providers, to maximize the performa...

... CEP engine presented indeed the current situation of the resources with minimum delay, since the events were being identified in less than 300 ms from the moment the data were received in the engine, regardless of the number of the number of the rules that were being triggered at the same time, as also depicted in Fig. ...

... There are innumerable non-monolithic applications that run in a distributed manner. For the proper deployment of these distributed applications in the virtual environments of 5G networks, it is crucial to capture their computing and networking requirements, as well as to monitor their components at runtime and adapt to any environment changes may appear [17] in order to make possible their consistent instantiation inside of 5G. Thus, the applications will be ready to be deployed in 5G environments, following and extending the cloud-native rules of the containerization, the dynamic orchestration, and the micro-services orientation [12]. ...

The new-coming 5G network is considered to be one of the most significant innovations today. This is due to the opportunities that is going to provide to the vertical industries. 5G infrastructures will introduce a new way for low-delay, reliable deployment of services. In fact, such infrastructures can be used for the placement of application services in the form of application graphs. An application graph consists of several application components (i.e. micro-services) that may be hosted in the same infrastructure or in different ones. Conflicting requirements that arise when deploying in such infrastructures are now handled through network slicing, which regards a way for partitioning conventional network and computing resources into virtual elements. In this paper, we define a universal application metamodel of a 5G compatible application in order to guarantee the annotation of each application descriptor with its proper requirements for their fulfillment at the instantiation time. In terms of application architecture, we consider each application graph as a service mesh topology in order to adopt this novel service architecture as a dominant methodology that is well fitting in the promising 5G capabilities.
