  The rise of the Internet of Things (IoT) has opened new research lines that
focus on applying IoT applications to domains further beyond basic user-grade
applications, such as Industry or Healthcare. These domains demand a very high
Quality of Service (QoS), mainly a very short response time. In order to meet
these demands, some works are evaluating how to modularize and deploy IoT
applications in different nodes of the infrastructure (edge, fog, cloud), as
well as how to place the network controllers, since these decisions affect the
response time of the application. Some works in the literature have approached
this problem by providing separate plans for deployment and placing of
controllers. However, this approach makes sub-optimal decisions, that
complicate guaranteeing the demanded response time. To guarantee an optimal
response time, it is crucial to solve the problem in a single effort that
considers both, the networking and computing dimensions. In this work, we
analyze the influences between the response time of computing and networking in
edge computing environments with SDN networks, merging both optimization
efforts into a single one and proposing a solution to the joint problem. Our
evaluation shows that our proposal can shorten response time by up to 28.97%
