Abstract

Abstract. Massively Multiplayer Online Role-Playing Games (MMORPGs) are very sophisticated applications, which have significantly grown in popularity since their early days in the mid-90s. Along with growing numbers of users the require-ments on these systems have reached a point where technical problems become a severe risk for the commercial success. Within the CloudCraft project we investi-gate how Cloud-based architectures and data management can help to solve some of the most critical problems regarding scalability and consistency. In this article, we describe an implemented working environment based on the Cassandra DBMS and some of the key findings outlining its advantages and shortcomings for the given application scenario.
