load-balancing

What are the advantages and disadvantages for Master/Slave type mysql architectures vs load balancing web servers with read only db's in each using a separate server holding a mysql database just for the writes? Master/Slave type architecture is useful for when your application is "read heavy", that is a majority of connections to the database are for reading data as opposed to writing data. Master/Slave allows you to scale out your application just by adding more hardware. Simply create a copy of the database on a new box and add it as a slave to the master. With regards to load balancing web

I have a web application with two different sites. Each can be accessed via HTTP. When you access Site #1, it will serve that site directly. When you access site #2, it will actually connect to site #1 behind the scenes via REST API calls. This architecture is shown in the diagram below. All instances shown (in blue) have ONLY private IP addresses. Both Load Balancers are internet-facing because people from outside the VPC need to access the application. Each autoscale group has an associated security group which is applied to each of its' instances. How can I configure LoadBalancer #1 to

I've setup an application (Django and nginx) at GCE with an HTTP Load Balancing. I created 2 global forwarding rule. 1 for HTTP and the other for HTTPS. This gave me 2 ip. https: 130.211.11.247:443 http: 130.211.15.15 I added the HTTPS IP (130.211.11.247) in my DNS A Record for my domain dvotedfan.com and that works perfectly if I access https://dvotedfan.com My problem is that it wont work if I try http://dvotedfan.com (Error 404). If I use the IP provided by the HTTP IP at 130.211.15.15 will it work. Since I know I can't add more then 1 IP for a DNS A Record how do I make the http://dvotefan

I not sure if this is possible (it wasn't last year according to the internet), but i'm hoping its available now. Is there any way of using google load balancer to force https connection only, ie. get the load balancer to redirect http requests? I can do it at the backend server, but i would rather have this handled by the load balancer. Thanks in advance, Max I think not. As far as I know, forcing HTTPS is not a managed feature of Google Cloud Load Balancer. It will not redirect HTTP to HTTPS for you. You can either drop the support of HTTP, or do the redirection in the backend. But it's

I am trying to use clustered keycloak docker behind the A10 load balancer. I am trying access all the request by https from the client application. My issue is that the same setup is working when we try to access keycloak has HTTP but at the same time when we try to access this has HTTPS it is not working. Can anyone help me to solve this issue? Please let me know whether the issue is in the keycloak level or A10 load balancer level. I don't know A10, but you have to ensure that it sets the request headers X-Forwarded-For and X-Forwarded-Proto . Then you have to configure Keycloak (Wildfly,
