Is it true that mainframes are not a good platform for application

development? What role is CA playing through Mainframe 2.0?

Actually, mainframes have historically been an ideal platform for

application development. That is why most of the worlds most critical

applications were written for the mainframe and continue to run on it. More

recently, IT organizations have developed a preference for distributed platforms

because of factors such as cost and flexibility. But significant enhancements

have been made to both the mainframe and mainframe development tools. As a

result, the mainframe is at least as cost-effective and flexible as any other

platformwhile offering greater scalability, reliability, security, and

energy-efficiency. This makes the mainframe the most compelling platform for

many kinds of application development and deployment.


Why do you think mainframes are making a comeback, especially as it is

still perceived to be an expensive platform to operate on?

That perception is changingespecially since IT organizations now realize

that distributed computing is heavily burdened with many hidden costs. In

addition, phenomena such as the rise of the Internet and e-commerce have made

the scalability, reliability, and security of the mainframe more appealing than

ever. As energy costs fluctuate, IT organizations are also realizing that they

are better off with a single, highly efficient system than with a large number

of smaller systems that consume energy much less efficiently.

What are the tangible and intangible benefits and savings received from a

mainframe set-up when compared to a distributed or conventional data center


The advantages that IT organizations can from the proper use of a mainframe

in the data center are many. Firstly, mainframes offer more cost-efficient

scalability. It is much easier and economical to add capacity on a mainframe

than it is to keep adding additional servers as each server has to be

installed, monitored, patched, etc. Next, it provides greater reliability as

every aspect of a mainframe the operating system, the hardware, the power

supplies, etc. is designed for maximum reliability. With distributed systems,

you have to make a sizable investment in redundancy and custom configuration to

achieve the same uptime. The third benefit is better security.
