It becomes a stumbling block, says Aaron Graves, senior vice president for Linux at Citigroup, Without all of those building blocks you cant go forward with an implementation.
Although he was unwilling to name names, Graves says software for the databases and directories supporting his companys financial operations is a pain point.
Jeff Teisch, senior vice president at Brown Brothers Harriman, agrees that support is a problem. Teisch called on the industry to pressure vendors into converting their applications over to the relevant flavor of Linux. There are a lot of vendors that run Linux on Intel Corp. [processors], but they have to support their application running on Linux on zSeries.
Many financial organizations, including Brown Brothers Harriman, rely on IBM Corp.'s (NYSE: IBM) zSeries mainframe servers.
