In computing, a daemon (pronounced DEE-muhn) is a program that runs continuously as a background process and wakes up to handle periodic service requests, which often come from remote processes. The daemon prog
What is a Daemon? A Daemon is a type of computer program that runs in the background, performing various tasks without direct interaction from the user. It's like having a helpful little assistant that takes care of things for you. Daemons are commonly found in Unix and Unix-like operatin...
Suppose a heartbeat is configured for a primary server and a backup server. The heartbeat daemon -- which is a program that runs in the background -- runs on the backup server and listens to the heartbeats coming from the primary server. If the backup server does not hear the heartbeat...
In the realm ofvirtualisationandcloud computing, the hypervisor is a critical component that enables the seamless operation of multiple virtual machines (VMs) on a single host. While virtualisation is a technology, the hypervisor is its actual implementation. In this beginner’s guide, we will expl...
Unlike Docker, it does not require a separate daemon to run, and instead uses standard Linux tools such as systemd and cgroups to manage containers. It provides a command-line interface that is similar to Docker and supports a wide range of container images and registries. It also provides fe...
At its core, virtualization is the abstraction of computing resources from the hardware layer, allowing multiple virtual environments to run simultaneously on a single physical machine (the host) while ensuring full resource separation. These virtual environments, known as virtual machines (VMs) or gue...
The most important architectural difference between Podman and Docker is that Podman is daemonless, which brings in a key characteristic of Kubernetes: helping align local development practices to Kubernetes environments. Daemonless architecture doesn't rely on a process with root privileges to run cont...
Docker daemon: receives and processes requests from Docker clients, listens for Docker API requests, and manages Docker objects such as images, containers, networks, and data volumes. Based on the openedge computingcapability of IoT gateways, HuaweiEC-IoTSolution quickly adapts to the intelligent dat...
Red Hat Enterprise Linux (RHEL) 8.5 is now generally available (GA), and brings new features and improvements to help streamline deployments, optimize performance and help mitigate risk in your environments. Whether you're deploying RHEL on-prem, in the
