The software enables customers to scale their operations by delivering applications using OSI layer 4 to 7 load balancing. LoadMaster is available as a hardware appliance as well as a software-based load balancer that is available as a virtualized appliance and in Microsoft Azure and Amazon AWS.
It is Layer 7-protocol aware and can enforce network policies on Layer 3 to Layer 7 and with FQDN using an identity-based security model that is decoupled from network addressing. Cilium implements distributed load balancing for traffic between Pods and to external services, and is able to fully replace kube-proxy, [ 53 ] using XDP , socket ...
Server-load balancing uses one or more techniques including service-based (global load balancing) or hardware-based (i.e. layer 4–7 switches, also known as a web switch, content switch, or multilayer switch) to share traffic among a number of servers or web caches.
Cloud load balancing reduces costs associated with document management systems and maximizes availability of resources. It is a type of load balancing and not to be confused with Domain Name System (DNS) load balancing. While DNS load balancing uses software or hardware to perform the function, [2] cloud load balancing uses services offered by ...
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 ...
Load balancing can be performed on HTTP, HTTPS, VPN, or any TCP/IP traffic using a specific port. Load balancing often involves destination network address translation so that the client of the load-balanced service is not fully aware of which server is handling its requests. Some layer 4–7 switches can perform Network address translation ...
Application Layer Gateway (ALG) software or hardware may correct these problems. An ALG software module running on a NAT firewall device updates any payload data made invalid by address translation. ALGs need to understand the higher-layer protocol that they need to fix, and so each protocol with this problem requires a separate ALG.
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.
