HAProxy Technologies’ ALOHA is a plug-and-play load-balancing appliance that can be deployed in any environment. ALOHA provides a graphical interface and a templating system that can be used to deploy and configure the appliance. [21]
The general format of the field is: [2] X-Forwarded-For: client, proxy1, proxy2 where the value is a comma+space separated list of IP addresses, the left-most being the original client, and each successive proxy that passed the request adding the IP address where it received the request from.
detects when a backend server fails or recovers, and bases its load balancing decisions on this information: if a backend server fails, it will not receive requests until it recovers; decrypts https requests to http ones; IPv6 support; can load balance from IPv6 clients to IPv4 servers and vice versa; rejects incorrect requests
Load balancing can optimize response time and avoid unevenly overloading some compute nodes while other compute nodes are left idle. Load balancing is the subject of research in the field of parallel computers. Two main approaches exist: static algorithms, which do not take into account the state of the different machines, and dynamic ...
Large websites and content delivery networks use reverse proxies, together with other techniques, to balance the load between internal servers. Reverse proxies can keep a cache of static content, which further reduces the load on these internal servers and the internal network.
The term is generally attributed to a 1990 article discussing firewalls by Marcus J. Ranum, who defined a bastion host as "a system identified by the firewall administrator as a critical strong point in the network security. Generally, bastion hosts will have some degree of extra attention paid to their security, may undergo regular audits, and ...
The "passivity" agreement FDIC wants BlackRock to sign is designed to assure bank regulators that the giant money manager will remain a "passive" owner of an FDIC-supervised bank and won’t exert ...
LVS director: load balancer that receives all incoming client requests for services and directs them to a specific "real server" to handle the request; Real servers: nodes that make up an LVS cluster which are used to provide services on the behalf of the cluster; Client computers: computers requesting services from the virtual server
