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 time and avoid unevenly overloading some compute nodes while other comp...
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 ...
1. 서론 이전 포스팅을 통해서 Envoy Cluster Manager의 역할에 대해서 살펴봤습니다. Cluster Manager는 Cluster 관리 뿐만 아니라 Multiplexer 및 Subscription 생성에 관여합니다. 이번 포스팅에서는 Cluster Manager에서 관리하는 Cluster 내부에서 지정할 수 있는 Load Balance...
Editor’s note: this post is part of a series of in-depth articles on what’s new in Kubernetes 1.11 · Per the Kubernetes 1.11 release blog post , we announced that IPVS-Based In-Cluster Service Load Balancing graduates to General Availability. In this blog, we will take you through a deep dive of the feature. IPVS (IP Virtual Server) is built on top of the Netfilter and implements transport-layer load balancing as part of the Linux kernel. IPVS is incorporated into the LVS (Linux Virtual Server), where it runs on a host and acts as a load b ...
XDP Load Balancing Support: eXpress Data Path (XDP) is the fast-lane for networking in the Linux kernel, built on eBPF. We've extended our existing eBPF kube-proxy replacement to accelerate service forwarding by 5x in our tests while dramatically reducing CPU consumption at the same time. (More details) · Cluster-wide Flow API: Hubble Relay builds on the solid core of Hubble and Cilium to provide deep observability across the entire cluster via a centralized API with minimal overhead. (More details) ...
This paper deals with the comparison of different load balancing strategies for massively parallel computations on clusters. There are four different strategies presented - static versus dynamic lo...
In this topic, we provide you with an overview of the Network Load Balancing \(NLB\) feature in Windows Server 2016. You can use NLB to manage two or more servers as a single virtual cluster. NLB e...
Load Balancing : 클라이언트의 request를 여러 서버로 분배하여 부하를 분산 ▼ Sticky Session : 첫 요청 이후의 모든 요청을 특정 서버로 고정하는 방법으로 세션을 관리한다.(cookie, 클라이언트의 IP tracking로 고정) 단점 : LB가 정상적으로 작동하지 않을 수 있고, 특정 서버에만 과부하가 올 수 있다. 특...
