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.
