Companies will also be upgraded to Solaris 10 when it ships at the end of the year at no additional cost, giving them access to new technologies like dynamic tracing, dynamic file system, predictive self healing and N1 Grid Containers, as well as optimized 64-bit Solaris support for Opteron-based systems. This promotion is available through the end of the year.This move follows Suns February announcement of free hardware for its U.S.-based developer network community. The Java Enterprise Developer Promotion, which ended June 30, included an entry-level Opteron-based Sun server, called the V20Z and was priced at $2,750, plus tools, support and services. That promotion cost $4,497, paid in three annual subscription payments of $1,499."Sun developers can now get hardware, software and development tools for a single, low annual subscription fee," said Schwartz at that time, adding that Sun was considering making a similar offer on its enterprise SPARC servers. Dana Gardner, a senior analyst for application infrastructure and software platforms at the Yankee Group, said the existing Java Enterprise System business model is steadily changing how companies evaluate and select infrastructure software. "This announcement will spur wider examination of the benefits," he said. Sun is also extending its existing special promotion for qualified small businesses through the end of this year. Sun officials first announced the promotion at the iForce conference in San Diego in April. Under this promotion, companies who qualify and have less than 100 employees will receive the Java Enterprise System software free of charge for one year.
