The state-change notification (SCN) service allows an iSNS server to issue notifications about each event that affects storage nodes on the managed network. Each iSNS client may register for notifications on behalf of its storage nodes, and each client is expected to respond according to its own requirements and implementation.
Docker clients connect to registries to download ("pull") images for use or upload ("push") images that they have built. Registries can be public or private. The main public registry is Docker Hub. Docker Hub is the default registry where Docker looks for images. [22] [26] Docker registries also allow the creation of notifications based on ...
The server or servers can be hosted locally or with a provider, privately hosted cloud services allow applications and data to remain under the control of the respective users.

OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, including containers (LXC, Solaris Containers, AIX WPARs, HP-UX SRP Containers, Docker, Podman), zones (Solaris Containers), virtual private servers (), partitions, virtual environments (VEs), virtual kernels (DragonFly BSD), and jails ...
Anycast is a network addressing and routing methodology in which a single IP address is shared by devices (generally servers) in multiple locations. Routers direct packets addressed to this destination to the location nearest the sender, using their normal decision-making algorithms, typically the lowest number of BGP network hops.
These include agents installed on the target system, "special agents" running on the monitoring server and communicating with the API of the target system, the SNMP API for monitoring, for example, network devices and printers, and HTTP/TCP protocols to communicate with web and internet services. By default, Checkmk follows the "pull principle ...
The most common form of black hole is simply an IP address that specifies a host machine that is not running or an address to which no host has been assigned.. Even though TCP/IP provides a means of communicating the delivery failure back to the sender via ICMP, traffic destined for such addresses is often just dropped.
The subject of the terms is thus important here: whether the focus of a discussion is the server hardware, server OS, functional service, software service/process, or similar, it is only if there is a single, consistent subject of the discussion that the words uptime and availability can be used synonymously.
