When Pradeep Mannakkara took the CIO position at Rosetta Stone, he encountered an IT infrastructure that was nearly the same age as the 21-year-old language-learning company. So Mannakkara established a plan to not only update, but also transform Rosetta Stone's technology stack and its 70-person IT department. Since starting in 2011, he has shifted much of the aging infrastructure to cloud-based platforms and added more mobile applications and state-of-the-art technologies. He says the changes achieved his goals of enabling a more efficient workflow and fostering innovation, while also increasing the strategic value of the IT organization.

Gino Pokluda had a problem: The database system at Presbyterian Health Plan in Albuquerque, N.M., where Pokluda serves as manager of service improvement and innovation, was becoming increasingly expensive and unwieldy, requiring about 80TB of storage for 13 database environments.

Here Pokluda, who manages all production, test and development environments for the company, discusses the database system overhaul and shares other IT management insights.
