openCoT: The opensource Cloud of Things platform

In order to address the complexity and extensiveness of technology, Cloud Computing is utilized with four main service models. The most recent service model, function-as-a-service, enables developers to develop their application in a function-based structure and then deploy it to the Cloud. Using an optimum elastic auto-scaling, the performance of executing an application over FaaS Cloud, overcomes the extra overhead and reduces the total cost. However, researchers need a simple and well-documented FaaS Cloud manager in order to implement their proposed Auto-scaling algorithms. In this paper, we represent the openCoT platform and explain its building blocks and details. Experimental results show that executing a function (invoking and passing arguments) and returning the result using openCoT takes 21 ms over a remote connection. The source code of openCoT is available in the GitHub repository of the project (\code{www.github.com/adanayi/opencot}) for public usage.
