Low-power operating system runtimes used on IoT microcontrollers typically provide rudimentary APIs, basic connectivity and, sometimes, a (secure) firmware update mechanism. In contrast, on less constrained hardware, networked software has entered the age of serverless, microservices and agility. With a view to bridge this gap, in the paper we design Femto-Containers, a new middleware runtime which can be embedded on heterogeneous low-power IoT devices. Femto-Containers enable the secure deployment, execution and isolation of small virtual software functions on low-power IoT devices, over the network. We implement Femto-Containers, and provide integration in RIOT, a popular open source IoT operating system. We then evaluate the performance of our implementation, which was formally verified for fault-isolation, guaranteeing that RIOT is shielded from logic loaded and executed in a Femto-Container. Our experiments on various popular microcontroller architectures (Arm Cortex-M, ESP32 and RISC-V) show that Femto-Containers offer an attractive trade-off in terms of memory footprint overhead, energy consumption, and security

Gossip-based service discovery (and more) for large distributed systems.
After reading this article, you will know what these interfaces are, what's the difference between them, when to use them, and how to create them
SigNoz is an open-source APM. It helps developers monitor their applications & troubleshoot problems, an open-source alternative to DataDog, NewRelic, etc.
Uptrace is an OpenTelemetry-based observability platform that helps you monitor, understand, and optimize complex distributed systems. Have confidence in your production and deliver better code faster than ever before.
An Open Source Observability Platform: Unify Session Replays, Logs, Traces, and Errors – All Without the Datadog Price Tag
Queueing theory is the mathematical study of waiting lines, or queues. We use queueing theory in our software development, for purposes such as analyzing and optimizing our practices and processes, such as our customer service responsiveness, project management kanban planning, inter-process communication message queues, and devops continuous deployment pipelines.
