Hi
We are possibly upgrading to Websphere 6.1 from WS 5.1.1.10, and I need some advice.
Our production and UAT / Staging environments will at some point require vertical and horizontal scaling for redundancy and failover. From my brief look , it would appear that we'll need
WebSphere� Application Server Network Deployment V6.1 Our other
test environments are Sys and Dev. A fully scaled Application Server environment seems here to be overkill, as at this point we're testing the business logic, so some other (less expensive!) Websphere option would seem to make sense. As there is potential for a number of projects to be on the go simultaneously, we'll need numerous instances of the Application Server each containing different instances of the middleware (which would ultimatley be merged at UAT prior to release). Would this point us to licences for
IBM� WebSphere� Application Server, V6.1 as a less heavyweight version of the networked edition? Is it too simplistic to think of using the Community Edition for development? And if we use the Community Edition, we can run it inside Eclipse, avoiding the purchase of WS6.1 version of WSAD.
Having the full Network Deployment option across all environments seems like overkill to me, and would also be prohibitivly expensive. Our hardware is set out as follows:
Prod: 2 Servers, Dual 3.8GHz processor(HS20), 4Gb Ram, 40Gb Disk
UAT: Virtual Server x2, LS41 Quad AMD Opteron,
SYS: Virtual Server, HS20 Dual Processor, 2Gb Ram, 40Gb Disk
DEV: Virtual Server, HS20 Dual Processor, 2Gb Ram, 40Gb Disk
Any recommendations gratefully received!
