Identity / Access Management
”Table Stakes” in Mobile Security are high
• Mobile Apps handle finances, payment, medical…
There are very few developers who can build low-level
security services good enough for public internet apps
Fortunately, there are very good existing solutions

• Cross-Platform Development usually focuses on
Frameworks and Tools:
• PhoneGap/Cordova, Xamarin, React Native, Unity
• But what if we reduced API calling to syntax?
Most mobile devices can issue an HTTP/S request
JSON handling is equally ubiquitous
Developers already know how to do this!

Key Messages
• Don’t Re-invent the Wheel
• For simple interactions with AWS, use Mobile Hub to see how the SDKs work
on Mobile Platforms.
• Use REST API driven logic with JSON payloads to level the playing field
across platforms and devices. Use API Gateway + Lambda for Scalability
• For Security and other ”Table Stakes” Mobile Features, use User Pools and
IAM Security.
• Take advantage of free and inexpensive solutions that meet your
needs with minimum investment
• For QA, use Device Farm to get the benefit of automated testing across many
devices inexpensively.
• Your (and your company’s) time is your greatest asset. Invest it
developing a great experience for your Customers
