New sectors such as financial services are expected to increasingly turn to open source tools More than 40 percent of organizations in Ireland will use some form of open-source software in 2006, according to a study by iReach, a research company in Dublin.The growing use of open-source software will be driven by several factors, said iReach. While telecommunications operators, technology companies, and the government have historically been open source users, new sectors such as financial services are expected to increasingly turn to open source tools. Reduced security concerns and the more prevalent ability to customize the software are attracting those new users to open source products, iReach found.The open source community may also find some new users in Ireland due to a growing interest in IP (Internet Protocol) telephony. Many companies are considering deploying open source IP PBX products and iReach expects vendors to increase their support options for open source telecommunication solutions during the year. Beyond the corporation, iReach also expects to see open source products reach further into homes.Overall, spending on enterprise software will increase by 5 percent in 2006, the researcher found. Database, messaging, integration and business intelligence software will account for a growing proportion of enterprise software investments.In December, iReach began releasing results of a wide-reaching study of 250 CIOs in Ireland regarding their IT and telecom expectations for 2006. IReach, part of the Next Utility family of companies, has been slowly releasing the results and this week revealed its predictions for open source in 2006. Software DevelopmentOpen Source
