Conclusion: Linux on the IBM mainframe (z/Linux) has been available since 2000 but is not widely adopted. As IBM increases its resources promoting z/Linux in Asia-pacific it is an idea that will be raised more frequently in this region. While recent advances in z/Linux (e.g., 64-bit implementation) make it a powerful and technically viable platform, with some organisations reporting significant benefits in specific circumstances, z/Linux will remain a niche solution rather than a common alternative to Lintel and Wintel.

The factors involved in making a decision to migrate Linux from Intel to System Z are extensive and complex, ensuring that the adoption of z/Linux in Asia-Pacific will remain slow and usage will stay very low though 2010.
