Question : Interview question on Websphere clustering

Hi Experts,

           I recently has an interview where interviewer asked me the concept clustering. I explained that quite well.
          His next question was: How do you implement clustering in Websphere (Thats the server we use)
         I have worked on websphere for more than a year now, but other than deploying application, configuring data sources, we are not provided with any other rights.

         so what would be the best answer from an interview point of view for the question:

       "How do you implement clustering in Websphere"

Answer : Interview question on Websphere clustering

There are two ways of implementing clustering on WebSphere

1) Vertical scaling
2) Horizontal scaling

In vertical : you create similar instances on the same Physical machine
In horizontal:  you create similar instances on a different physical machine

for best availability and scaling : create both vertical and horizontal


) Install the Network Deployment Manager
2) Install one or more AppServers as needed
3) On the AppServers go to the bin folder and run the addNode command to add the Node  (addNode.sh) to the Deployment Manager
4) syncNode.sh if needed.

I have attached the  next steps to be done thro the GUI. Hope this helps
