Migration of Arcgis 10 to 10.1

[shafitrumboo]

We have distributed architecture in arcgis as shown in attached image now can we create same architecture in 10.1.
we are using four machines with two arcgis licencees only used in SOC machine that is Machine 3 and Machine 4

you can see Deployment scenarios: http://resources.arcgis.com/en/help/main/10.1/index.html#//015400000488000000

in your scenario can be without cluster ags:
In 10 have you HA on web server? Because in this configuration (10.1) you have HA on web server. In 10.1 you haven't som.

Thanks for your reply. Since we have now 10.2 is the same applicable to current version of Arcgis server.

1. What do you mean by HA and where is network load balancer?


2. Do we require still only two licences of arcgis server and same time we are using power of four machines?


3. Do you recommend any new architecture?

"HA" means High Availability.  At the 10.2 version of ArcGIS for Server, the Site load balances itself.  There isn't really a need for a separate load balancer anymore, although there may be one or two specific use cases that are not common in most environments.  You should know that ArcGIS for Server's licensing model is by the CPU core; so for every machine that runs a SOC instance you would require licensing on all of its cores.  I suppose this would be a function of how many servers you add to your ArcGIS for Server Site.

Currently we are using ArcGIS 10 and we have High availability ArcGIS server architecture in production with windows network load balancing software but we found this is not working fine in scenario

1. We have IIS and SOM working on both machines say web1 and web2. Sometimes for some users there web request lands on web2 and it responds with error although IIS is working fine but our Network load balancer doesn't recognize this behavior. And for other user request is landing on web1 that is responding as per expectations. With the result we found our application was working for some user and for some not. We usually restart ArcGIS Services (SOM and SOC) on other machine (web2)

Question 1: We are going to Migrate to ArcGIS 10.2 can I anticipate this problem again?
Question 1: DO we have any other Network load balancer which can take care of this kind of situations
