Overview of MSTP
MSTP is a multiple spanning tree protocol that allows multiple spanning trees to run in a switching environment. Each spanning tree is called an instance. MSTP trims the routing lo
Category: Load Balance
Load Balance is based on the existing network structure, and allocates requests to multiple operating units for execution, such as Web servers, FTP servers, enterprise key application servers, and other mission-critical servers, so as to complete work tasks together . It provides a cheap, effective and transparent way to expand the bandwidth of network devices and servers, increase throughput, strengthen network data processing capabilities, and improve network flexibility and availability.

In a small store, what is the recommended load test policy (ie, analog large number of clients) server applications?
I developed a web-based multi-component software system designed to run on any number of machines. I assume a typical 1 to 4 machine setup.
I want to take system testing seriously, and I have

Configure Haproxy to implement load balancing
1. Introduction to haproxy
HAProxy is a free and open source software written in C language[1], which provides high availability, load balancing, and applications based on TCP and HTTP Progra
Keepalived + Haproxy builds high available web clusters
Haproxy is currently a popular cluster scheduling tool. There are many similar cluster scheduling tools, such as LVS and Nginx. In comparison, LVS has the best performance, but it is relatively com
Set UI dashboard on single-node Kubernetes clusters set using Kubeadm
I followed this tutorial https://kubernetes.io/docs/getting-started-guides/kubeadm/ to set up Kubernetes on Ubuntu 16.04 vServer
On this node I want to make Kubernetes Dashboard available but
Cluster extruded nodes in Graphviz
I want to draw several related subgraphs in GraphViz. When I draw simple nodes, it looks very beautiful:
Resources:

A1 -> A22;
A1 -> A23;

Investigation ideas in the K8S cluster encounter ETCD cluster faults
When creating an instance in the k8s cluster, it was found that the etcd cluster status failed to connect, causing the creation of the instance to fail. So I checked the cause.
Here is the he
