This paper deals with network architecture which is a combination of electronic commerce and security systems in the typical Internet ecosystems. The e-commerce
model that is typically known as online shopping can be considered as a multichannel
queueing system. In the other hand, stochastic security system is designed for improving
the reliability and availability of the e-commerce system. The security system in this
paper deals with a complex system that consists of main unreliable servers, backups,
and repair facilities to repair the broken servers. The results are applied for analyzing the
current Internet ecosystem, and the mathematical methods can be also applied to the
various areas such as human resources, manufacturing processes, and military operations.
The solution presents the analytical solutions of the combined architecture of two
queueing systems, and these tractable results are used for demonstration in the
framework of optimization problems.
