Re: Is VMS losing the Financial Sector, also?

Here is something to consider. A new trend is developing (and being
promoted by big SW companies like SAP) is Tier consolidation whereby OS
instances are reduced by placing the App server(s) on the same server as
the DB. Since most servers are only running less than 20% in peak time,
this makes a lot of sense - you just need to ensure things like workload
mgmt are in place to ensure one process does not do something silly and
impact other processes. No big deal as this has been a practice on many
other platforms for years (including OpenVMS).

You not only eliminate OS instances, but also network latency issues, as
well as provide a common OS environment for doing batch jobs.

Now, ask your Dev team that is hot for Linux how they plan to address
this growing trend in the future i.e. a common platform for the App
server, db and batch environment.

Want to bet they will say they need a separate server for each
Application and DB?

They may or they may not.

There are nothing preventing them from doing the same thing
on Linux.

Why do you think Xen was added to RHEL 5 ?
