API Challenges
OnboardingDifficult to onboard and manage app developers and API keys
Scale Traditional integration technologies not built for web scale – billions of interactions
AgilityInability of IT to meet the business demands of delivering volume of LOB apps faster
SecurityUnable to secure critical assets exposed beyond trust boundaries
VisibilityLack of insight into usage, performance, users, products, patterns, devices, anomalies
