With the promise of potentially unlimited power and scalability, cloud computing (especially infrastructure as a service [IaaS]) supports the deployment of reliable services across several application domains. In the Internet of Things (IoT), cloud solutions can improve the quality of service (QoS), fostering new business opportunities in multiple domains, such as healthcare, finance, traffic management, and disaster management.

Recent technological advances have disrupted the current centralized cloud computing model, moving cloud resources close to users: The Cloud Continuum is providing these capabilities. Moreover, microservice approach allows to instantiate the new paradigm of Continuum that’s driven by the significant increase in resource capacity/capability at the network fog/edge, along with support for data transfer protocols that enable such resources to interact more seamlessly with datacenter-based services. One of the near future challenges is represented by the management of even more high distributed systems along with the need to federated those environments. The automatic deployment of microservices is becoming a must, importantly they have to be composed and interconnected over IoT, Fog, edge and cloud infrastructures, thinking to Security. Various stakeholders (Cloud providers, Edge providers, Fog provider, Security provider, Application providers, IoT DevOPs, and so on) can contribute to the provisioning of new IoT services and applications in Federated Environments. Osmotic Computing can be seen as a possible answer to smoothly manage the challenging services against the Cloud Continuum of the future. Here new models and program paradigm are discussed, inspired by Nature.
