the increasing share of renewable energy sources in relation to the total generated energy increases the requirements for the flexibility of energy systems. this paper explores some methods and technologies for building an interoperable interface between the IoT devices related to energy consumers and producers in order to allow reliable operation and savings based on demand side management and energy storage. In the particular showcase the IoT devices use public data from the distributes service operator or the energy exchange to reduce the electrical energy cost for the customer, but also to reduce the peaks in the generation profile.

this work is devoted to an actual survey on advanced security and ensured user privacy for (Highly-) distributedsystems. the last term belongs to thin and thick apps, robot and mobile apps, (micro-)service-oriented applications, and IoT applications. the most dangerous vulnerabilities, intrusion analysis techniques and models, and countermeasures to increase the safety of the cyber-systems are discussed. AI-based methods are favored nowadays. However, generative models provide some new risks and vulnerabilities. EU legal regulations are considered. Several case studies (among others, for telemedicine and e-health) are examined.

distributed reconfigurable intelligent surfaces (RISs) provide rich macro-diversity coverage due to different locations of the RISs, which is beneficial to combat coverage holes. However, the system performance relies on the effective coordination of multiple RISs. thus, the resource allocation scheme for distributed RIS-assisted multiuser system is a crucial challenge. To tackle these issues, joint power allocation, phase shifts and communication scheduling design for distributed RIS-assisted systems is investigated in this paper, where all RISs simultaneously and cooperatively serve multiple users. To overcome the formulated nonconvex maximization problem, the original maximization problem is decoupled into three subproblems and solved in an iterative manner. Numerical simulations are conducted to demonstrate that the considered solution outperforms the existing benchmark and achieves a near-optimal sum rate.

Making Internet-of-things (IoT) applications adaptive under unexpected failures and resource fluctuations can be challenging. In this demo, we present ImmunoPlane, a middleware system that brings adaptivity to IoT applications. Using a distributed stream-processing application, we demonstrate how ImmunoPlane transparently configures and deploys the application such that it can adapt to network congestions and random device failures.

Microservice architecture is widely adopted among distributedsystems. It follows the modular approach that decomposes large software applications into independent services. Kubernetes has become the standard tool for managing these microservices. It stores sensitive information like database passwords, API keys, and access tokens as Secret Objects. there are security mechanisms employed to safeguard these confidential data, such as encryption, Role Based Access Control (RBAC), and the least privilege principle. However, manually configuring these measures is time-consuming, requires specialized knowledge, and is prone to human error, thereby increasing the risks of misconfiguration. this research introduces K8s Pro Sentinel, an operator that automates the configuration of encryption and access control for Secret Objects by extending the Kubernetes API server. this automation reduces human error and enhances security within clusters. the performance and reliability of the Sentinel operator were evaluated using Red Hat Operator Scorecard and chaos engineering practices.

Function-as-a-Service (FaaS) has become increasingly popular due to its ease-of-use operations, scalability, and low management overhead. However, the stateless nature makes it inappropriate for deploying applicationsthat require maintaining state data across series execution. this motivates state management for FaaS platforms, which is currently satisfied by integrating additional storage services or a central coordinator. In this paper, we propose a new approach for FaaS platforms to manage function states in a distributed way. Specifically, we utilize function-level checkpoint to maintain function state and enable state to scale withthe number of function instances. To synchronize state among multiple instances of the same function, we employ a synchronization mechanism supported by consensus protocols. Compared to existing works, our new approach distributes the burden of state management across all nodes and does not rely on additional services. In evaluation, we compare our approach to baseline system with a micro-benchmark and three representative applications. the results show that our approach can keep strong consistency of state between functions and reduce function execution time significantly.
