Dear Rajesh, Apologize for delay in response.
You mean the netscaler api's used to create the autoscale functionality? > Yes. And I just found a document about Netscaler config: http://support.citrix.com/proddocs/topic/ns-system-10-map/ns-autoscale-automatic-scaling-in-cloudplatform-env-wrapper-con.html more info from: http://support.citrix.com/servlet/KbServlet/download/30564-102-684000/NS-CommandReference-Guide.pdf Also looking through Netscaler plugin implementation into ACS, I can understand the operation. Btw, I'm confusing about this points: - When user change templateID in a AutoScale group, don't Netscaler call ACS to destroy old VMs? Then, there are two type of VMs in that group: one with old template and one with new template. Is it right? Thanks, -- N.g.U.y.e.N.A.n.H.t.U
