Of course. But then the problem of short lifetime still remains.
Not a problem for a lot of companies. They like to "roll over" their
server hardware every 3 years or so anyway.
That is one year too much for openSuSE ;-)
There must be good
"accounting reasons" as technically; server-class hardware runs for
a decade or more if you look after it reasonably well.
The same applies for the operating system. But like one runs out of
warranty and spare parts supply for the hardware the operating systems
runs out of service and support. There are only a few exceptions to
this.
If you're using SLES, then you will have an older kernel than
openSuSE; and migration to new server hardware can be hampered.
Somebody will have to back-port drivers.
This is done by Novell or the hardware companies. If one finds support
for Linux in server hardware (or business class PCs), it will be for
Red Hat or SLES/D, not for any community distribution including Debian.
This is different for desktop or especially notebooks where in general
the latest kernel and distribution works best.
Dedicated server distributions for professional use also have a
documented and tested upgrade path.
The security of operation is in the _maintenance_. Nothing prevents
a third party from providing the same level of support.
SLES support is from Novell. They too are a "third party" on Linux
systems.
SLES is a typical Linux system.
Why not new hardware? The old hardware can be redeployed to other
tasks; perhaps as a warm standby, or as part of a cluster.
So you suggest replacing the hardware every two years? IMO a waste of
time and money.
Most likely this additional time spent on administration
will cost more than a license fee for SLES or another server
distribution. It also adds to downtime which, depending on the
business, can be costly.
It would be very foolish to cut over to a new, untested system.
Of course. But the argument with the labour involved stays. For any
business which has to pay for IT services on their central server
installations in house or externally the license fees are almost
irrelevant. It will be different for e.g. a web hosting company with
hundreds of Linux boxes running as web servers. Here using a free
distribution with short life time might be interesting.
