This document summarizes a presentation on cloud interoperability given by Lockheed Martin. It discusses Lockheed Martin's vision to provide cloud services and solutions to customers through a unified catalog. This would allow customers to access infrastructure, platform, and software services from Lockheed Martin and third parties in a standardized way. It would also enable cloud brokering to provision resources from multiple public clouds to best meet customer requirements. The service catalog aims to give customers simplicity, transparency and security while reducing costs through greater choice and competition.
