Speed-to-market was one of the major reasons for choosing .Net. Hong said one of Cascade's most popular services is the development of PCS, which holds business logics useful to other telcos.

"After the project of developing China Mobile's PCS, we realized .Net can speed up development time tremendously," he said. "In the past two years, we also tried to use .Net for our client's projects and the results were pleasing with a much shorter development-cycle time."

For the same command, the coding required in .Net could be one-tenth of Java, said Hong. Besides development, .Net is also faster and easier in de-bugging. "Timing is very important, particularly when we are developing systems for our clients," he said. "A shorter development time means lower cost and higher profit."

In addition to quantity, Hong noted .Net also brings quality to the applications. The final products developed on .Net platform can often better meet client's SLAs with fewer bugs and more quality developers are also available in the market.
