Internet of robotic things : converging sensing/actuating, hypoconnectivity, artificial intelligence and IoT Platforms
The Internet of Things (IoT) concept is evolving rapidly and influencing newdevelopments in various application domains, such as the Internet of MobileThings (IoMT), Autonomous Internet of Things (A-IoT), Autonomous Systemof Things (ASoT), Internet of Autonomous Things (IoAT), Internetof Things Clouds (IoT-C) and the Internet of Robotic Things (IoRT) etc.that are progressing/advancing by using IoT technology. The IoT influencerepresents new development and deployment challenges in different areassuch as seamless platform integration, context based cognitive network integration,new mobile sensor/actuator network paradigms, things identification(addressing, naming in IoT) and dynamic things discoverability and manyothers. The IoRT represents new convergence challenges and their need to be addressed, in one side the programmability and the communication ofmultiple heterogeneous mobile/autonomous/robotic things for cooperating,their coordination, configuration, exchange of information, security, safetyand protection. Developments in IoT heterogeneous parallel processing/communication and dynamic systems based on parallelism and concurrencyrequire new ideas for integrating the intelligent “devices”, collaborativerobots (COBOTS), into IoT applications. Dynamic maintainability, selfhealing,self-repair of resources, changing resource state, (re-) configurationand context based IoT systems for service implementation and integrationwith IoT network service composition are of paramount importance whennew “cognitive devices” are becoming active participants in IoT applications.This chapter aims to be an overview of the IoRT concept, technologies,architectures and applications and to provide a comprehensive coverage offuture challenges, developments and applications
Performance Evaluation of Microservices Architectures using Containers
Microservices architecture has started a new trend for application
development for a number of reasons: (1) to reduce complexity by using tiny
services; (2) to scale, remove and deploy parts of the system easily; (3) to
improve flexibility to use different frameworks and tools; (4) to increase the
overall scalability; and (5) to improve the resilience of the system.
Containers have empowered the usage of microservices architectures by being
lightweight, providing fast start-up times, and having a low overhead.
Containers can be used to develop applications based on monolithic
architectures where the whole system runs inside a single container or inside a
microservices architecture where one or few processes run inside the
containers. Two models can be used to implement a microservices architecture
using containers: master-slave, or nested-container. The goal of this work is
to compare the performance of CPU and network running benchmarks in the two
aforementioned models of microservices architecture hence provide a benchmark
analysis guidance for system designers.Comment: Submitted to the 14th IEEE International Symposium on Network
