While service-based infrastructure can improve TCO and streamline IT management, it also presents some challenges that need to be met head-on. How do you ensure your data is secure in transit and available when you need it? How do you manage and communicate with your infrastructure? How do you enable service quality metrics and disaster recovery? And, how do you integrate data from legacy systems with data from web-based systems? Join AT&T and Informatica as they share their experience in building and managing cloud applications and infrastructure.
