Hello
friends,
After
lot of observations & reading I understood why people don't like
to buy Mainframe, The Three Stupidest Reasons Why Not to Buy a
Mainframe are
1.
Mainframes cost too much.
2.
We don’t have the skills needed to operate a mainframe
environment.
- Mainframes are old technology.After learning how some of these people are actually running their IT environments, I’ve come to believe that these are three truly stupid reasons not to adopt mainframe technologies.
- Mainframes Cost Too Much?
Even
though a mainframe can now be purchased for about $100,000 (the cost
of some rack systems), IT buyers still believe that mainframe
hardware is too expensive.
Really it is very
costly, But we need to look at the advantages provided by mainframes
over other IT infrastructure that is being normally used. Think about
following advantages of mainframe
a.
Management:
Defiantly for
operating the mainframe system we need skilled workers, but need less
number of administrators because thousands of people work on the same
server, Lets have look on following Example
A company serve
162 different customers-and over 3 million users-with six mainframe
administrators." If you’re running a distributed computing
environment, imagine how many IT systems, storage managers and
administrators you’ll need to serve 3 million users! That number
may well exceed 100 people. Now figure the cost for employee salary
and benefits for all of those people, and suddenly mainframe pricing
looks comparatively inexpensive.
b.
Security:
As I explained
in the last post that the mainframe server is not hacked yet. It is
highly impossible to hack the mainframe because the tight security
provided by RACF, a security client.
c. Consolidation/virtualization,
reduced power consumption and real estate savings:
By using the
mainframes server it is highly possible to save manpower, power
consumption & floor space. This is because virtualization is
made possible by using mainframe. If we use mainframes then we may
achieve 50 percent reduction in monthly Web hosting costs; an 80
percent reduction in data center floor space needs; significant
power consumption savings; and huge savings in middle ware costs.
Further, this executive saw a 50 percent reduction in hardware and
OS support effort.
2. Skill
Issue with mainframes:
The
people using UNIX/Linux and Windows IT shops honestly believe that
they don’t have the internal skills to operate a mainframe
environment, and that is acceptable
From last few years
IBM has already taken an initiative for mainframes education. That is
I am talking about IBM’s mainframe education
initiative at this time was called the “zSeries Scholars Program”
But, over the past two years, IBM has greatly expanded this program
as part of its “Academic Initiative Program”, a program that now
serves over 200 schools and universities around the world. And the
company has set a goal, as part of its mainframe charter, to help the
industry add 20,000 new mainframe skilled individuals by 2011.
- Mainframes Are "Old Technology"
Though mainframes
is the older technology, but it is not possible for any computer &
server to provide service like Mainframes, So though it is old, that
is like Gold. Anyway we can interface mainframes to the latest web
technologies & able to program mainframes using very modern
languages like JAVA, J2EE instead of using COBOL. But the is easiest
language & all banks who have mainframes use it. Now it is highly
impossible to replace those codes with newer one, Because those
programs contain lakhs of lines of code.
Summary
Observations
IT
buyers who look at mainframe TCO should find that mainframes are less
expensive to operate than distributed systems environments, in part
because of reduced staffing needs. Taken with the fact that
mainframes are clearly not old technology, these three arguments hold
no ground against exploring the possibility of mainframe
implementation.
