RIP (Real IP address): the IP address used to connect to the cluster nodes; DIP (Directors IP address): the IP address used by the director to connect to network of real IP addresses; CIP (Client IP address): the IP address assigned to a client computer, that it uses as the source IP address for requests being sent to the cluster
A cluster IP is a term in cloud computing to refer to a proxy that represents a computer cluster with a single IP address. [1] It is a term used by the cloud computing system Kubernetes (stylised as ClusterIP ) to provide load balancing to IP addresses for devices in the internal network.
Diagram illustrating user requests to an Elasticsearch cluster being distributed by a load balancer. (Example for Wikipedia.) In computing, load balancing is the process of distributing a set of tasks over a set of resources (computing units), with the aim of making their overall processing more efficient. Load balancing can optimize response ...
Network load balancing is the ability to balance traffic across two or more WAN links without using complex routing protocols like BGP.. This capability balances network sessions like Web, email, etc. over multiple connections in order to spread out the amount of bandwidth used by each LAN user, thus increasing the total amount of bandwidth available.
Software services, filesystems and network status can be monitored and controlled by the cluster suite, services and resources can be failed over to other network nodes in case of failure. The Cluster forcibly terminates a cluster node's access to services or resources, via fencing, to ensure the node and data is in a known state.
IPVS (IP Virtual Server) implements transport-layer load balancing, usually called Layer 4 LAN switching, as part of the Linux kernel. It's configured via the user-space utility ipvsadm(8) tool. IPVS is incorporated into the Linux Virtual Server (LVS), where it runs on a host and acts as a load balancer in front of a cluster of real servers.
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.
