For many years the high-tech industry has a noticeable distinction between consumer products sold to a mass of price-sensitive individuals and business products serving enterprises with large IT budgets. The consumer vendors provided no-frills products in high volume and fiercely competed to match the rapidly falling prices, of fast aging commodity hardware and software. The enterprise vendors provided cutting edge solutions, aimed at increasing productivity and profitability, and enjoyed a locked in, high margin business. Enterprises have traditionally invested in skilled IT departments, reliable and secure networks and data centers, and highly customized applications. These expenses were justified by considerable productivity gains. This old model of enterprise products backed by enterprise IT is being challenged by two paradigm shifts, arising from new technologies and changing behaviors in consumer markets. First, the web has produced a large number of consumer applications such as web mail, search, e-commerce and social networks. These applications not only lower costs, leveraging economies of scale, but also offer higher quality through continuous cycles of improvements. Agile methodologies allow developers to learn user behavior and immediately modify the product. The same web technologies have enabled a wave of enterprise SaaS (Software as a Service) applications (e.g, CRM, HR, data analytics).Yet, some business applications have not fully migrated, since most businesses have some unique business requirement that cannot be addressed by a generic SaaS application. The migration to SaaS make the enterprise IT and the on-premise enterprise systems fragmented and outdated. Second, smart mobile consumer devices have been rapidly adopted for business use. These provide knowledge employees with ubiquitous business access, and have become crucial for ensuring shorter response times and higher productivity. Consequently, the business is tied to the employee and not to the workplace or the office. In addition, these mobile devices access SaaS applications directly, bypassing the traditional enterprise on-premise infrastructure. In this talk, we will address some of the main problems facing this emerging enterprise IT model. As most business transactions are conducted between mobile users and web applications, many existing enterprise networks and security systems such as firewalls and data leak prevention have become obsolete. Similarly, solutions for providing infrastructure management, quality of service, reliability and survivability need to be redesigned and replaced. We will highlight legacy and emerging technologies that are impacted by these trends in academic research and new enterprise products.
