load-balancing

问题 Scenario: The website is hosted on three servers using IIS on each. All three servers are clustered using the network load balancing software that comes with Windows Server 2003. All three sites are configured to store the session state on a separate server that has been designated as a "state server". I have been asked to scale up the "state server". Is there a way that I can have more than one state server and synchronize state between them, so if one of the state servers goes down the

问题 I am quite confused about the roles of Ingress and Load Balancer in Kubernetes. As far as I understand Ingress is used to map incoming traffic from the internet to the services running in the cluster. The role of load balancer is to forward traffic to a host. In that regard how does ingress differ from load balancer? Also what is the concept of load balancer inside kubernetes as compared to Amazon ELB and ALB? 回答1: Load Balancer: A kubernetes LoadBalancer service is a service that points to

问题 I want to understand how ELB load balances between multiple availability zones . For example, if I have 4 instances ( a1, a2, a3, a4 ) in zone us-east-1a and a single instance d1 in us-east-1d behind an ELB, how is the traffic distributed between the two availability zones? i.e., would d1 get nearly 50% of all the traffic or 1/5th of the traffic? 回答1: If you enable ELB Cross-Zone Load Balancing, d1 will get 20% of the traffic. Here's what happen without enabling Cross-Zone Load Balancing: D1

问题 As title, we had a simple service design that uses a cxf:proxy endpoint inside an http-inbound enpoint, and the Mule server is behind load-balancer which does ssl offloading. When user requested with https ://url?wsdl, in the returned wsdl, we found mule writes the service address in http . Is there any way that we could change it to https here? We are using mule 3.5.2 here. PS. The Load-balancer is F5 and belongs to 'network team', we could ask for the X-Forwarded-Proto header, but only if

问题 I’ve got a lighttpd server behind an AWS load balancer. The ELB handles all the SSL stuff for me and forwards the requests to lighttpd over HTTP on port 80, setting the X-Forwarded-Proto header along the way. As I only want to have one specific page go via HTTPS and everything else over HTTP, I wanted to setup redirects in the lighttpd config file, like: $HTTP["scheme"] == "https" { $HTTP["host"] !~ ".*ttc/(index.html)?$" { $HTTP["host"] =~ "(.*)" { url.redirect = ( "^(.*)$" => "http://%1$1")

问题 How to dispatch 2 subsequent requests without a cookie from the same client to the same JBoss node? I have a multi-node setup with Apache , JBoss7 (with load balancing , sticky session and SSO ) and Tomcat . Here is the scenario: User enters https:///myapp on the browser Load balancer dispatches it to node1 , on the myapp.ear file. Since there is no authentication yet, myapp loads the unprotected client_redirect.jsp resource, which creates a JSESSIONID and returns to the client. The HTTP

问题 I am trying to configure a Kafka cluster behind Traefik but my producers and client (that are outside kubernetes) don't connect to the bootstrap-servers. They keep saying: "no resolvable boostrap servers in the given url" Actually here is the Traefik ingress: { "apiVersion": "extensions/v1beta1", "kind": "Ingress", "metadata": { "name": "nppl-ingress", "annotations": { "kubernetes.io/ingress.class": "traefik", "traefik.frontend.rule.type": "PathPrefixStrip" } }, "spec": { "rules": [ { "host":
