Can the worklight analytics server be loadbalanced using an IHS Server?
https://www-01.ibm.com/support/knowledgecenter/SSZH4A_6.2.0/com.ibm.worklight.installconfig.doc/monitor/t_installing_op_analytics_liberty.html?lang=en
For example, if the Liberty server is at host.ibm.com on port 8080 and the context root is analytics, then the wl.analytics.url property is as follows:
wl.analytics.url=http://host.ibm.com:8080/analytics/data
Could the host here be a IHS Server with WAS plugin configured to balance requests across multiple Analytics nodes?
Yes, but this shouldn't be necessary.
Worklight analytics uses Elasticsearch under the covers. When an anayltics request comes in from Worklight, the data is sent to Elasticsearch which will automatically route the analytics data to the correct node as long as the nodes have been setup correctly.
I suggest reading more about how Elasticsearch clustering works to see if it would be necessary to add an additional load balancer.

My client is currently evulating AKS which seems to be really promising. Our current platform is based on Azure VM's we provision ourselves. We would like to create private communication between both our existing platform and the managed AKS cluster but so far that does not seem to be supported yet.
Some example use cases for us are:
- Proxying incoming HTTP traffic via our main entrypoint, a Varnish server, to the new AKS environment so we don't have to change url's
- Accessing non publically exposed API's from the AKS environment
Right now the AKS cluster is it's a different subscription and resource group than other parts of our platform. The main reason we we can't connect though seems to be that it's not possible to specify which private IP range should be used when creating an AKS cluster.
Is there support planned for this or is there a reliable workaround?
Thanks for the inquiry, there's a workaround for the stated case, it's through the use of ACS Engine, "ACS Engine, for Azure Container Service Engine, is a CLI tool that helps to generate Azure Resource Manager templates to deploy Docker enabled clusters on Microsoft Azure. It works with all the orchestrators supported by ACS: Docker Swarm, Mesosphere DC/OS and Kubernetes"
So using this solution will allow you to integrate Azure Container Service Cluster into an existing Virtual Network.More details and step by step guide can be found here: https://blogs.msdn.microsoft.com/jcorioland/2017/01/10/how-to-integrate-a-new-azure-container-service-cluster-into-an-existing-virtual-network-using-acs-engine/
I found this great tutorial from Amazon on using cloud formation to provision an elb in front of a web server with auto scaling. What I want to do is extend this to also create a second elb with an app server behind it. I can figure out that part, but once I do I then want to configure the web server (I guess in httpd.conf to establish the connection from the web server to the app elb. does anyone have guidance on how to do this?
I'm trying to understand the topology of Worklight. Specifically how does a WL Server handles its applications.
If I understood correctly, a WL Server has a <httpEndpoint>. This means that a set of WL Applications will have their context root on that port. Right?
This means, If I want to put /worklightconsole on a custom port, I'll need a network installation instead of a standalone so that I can have a cluster of WL instances and each one will bind to a different port.
Did I understood this matter correctly? Then I can use a reverse proxy to needle my requests to the correct instance of WL Server.
Right?
Thanks in advance!

Yes the httpEndpoint entry defines the http and https port and the WL applications have their context root on these ports.
If you have different Liberty Servers with the same WL runtime, be sure that the you share the same database and same schema.
After that you can use a Web Proxy to load balance the requests between the different Liberty servers.
I'm on Weblogic AS 10.3.5, I have two managed servers pointed to a cluster, so I have two url, one for the first managed server, the other one for the second.
I will deploy my application on the cluster, so will I reach it on both the url? will the application deployed and running on both the servers?
How does it work? Can you give me some references, please?
Is it clear?
Thanks a lot!
First, you shouldn't be using WebLogic 10.3.5 anymore since it has reached the last stage of support called Sustained Support. Consider to upgrade at least to WebLogic 10.3.6.
Related to your question, I believe you are talking about a Web Application and how to access it. First you need to read about Load Balancing in a Cluster. For the web part (JSP and Servlets) basically you have to options: setup a Web Server (like Apache HTTP) to make use of the WebLogic Plug-in, that will then be connected to the WebLogic cluster. The other easier option is to simply use an LBR (load balance router hardware).
These are the "software" solutions you have for Load Balancing your web application in a clustered WebLogic:
WebLogic Server supports the following Web servers and associated
proxy plug-ins:
WebLogic Server with the HttpClusterServlet
Netscape Enterprise Server with the Netscape (proxy) plug-in
Apache with the Apache Server (proxy) plug-in
Microsoft Internet Information Server with the Microsoft-IIS (proxy) plug-in
You can read more about this options at the Configure Proxy Plug-ins documentation page for WebLogic 10.3.6.
Am Weblogic beginner.
I have created an application to test the JNDI load balancing. My application is deployed on Admin server that uses JNDI which is deployed on Cluster containing two servers(MS1, MS2). Know, my question is how can we know which server in the cluster is serving the request to client.
Thank you,
