Architecture of Real-Time Database in Cloud Environment for Distributed Systems

In every distributed system there is a need for a real-time database when working with a large amount of data and when quick response from a service is expected on the client side. Cloud companies do not offer real-time databases, therefore, in this paper we present the architecture of a real time database in cloud environment, as well as reviews of other papers dealing with this topic, analyzing their advantages and disadvantages. The above-mentioned real-time database attempts to store different kind of data, and our proposed solution is implemented in each distributed system service. Unlike other solutions, this real-time database will not occupy main memory-base because it is running in cloud environment. Also, we are proposing which cloud environment services can be used to implement this real time database. As an example, we are modeling one distributed system using Petri nets where solution can be applied.
