Scalable architecture of alert notification as a service

Internet-based communication defines two main types of services as Pull and Push services, depending on the side that sends the request for transmission of information. In contrast to Pull services, whose request for transmission is initiated by the client, Push service denotes a type of transmission where the request for a given exchange of information is initiated by the publisher or central server. The newly proposed Alert Notification Service (ANS) represents an important implementation of these Push services, for the sites that neither implement it or that think it is not worth to do it economically. In this paper we present details on system functionalities, architecture model, design, and integration of essential modules into a fully working system as a service. The main contribution is in design of a highly scalable solution for an elastic cloud architecture, by separating the static and dynamic parts, correspondingly assigned to different virtual machines.
