SDK


Mobile Hub as a Starting Point

• Generates Working Code to Explore in your

Development Environment

• Introduction to SDK-based Development with AWS

• Demonstrates code for a variety of AWS Services in iOS,

Android, and JavaScript


MOBILE HUB DEMO


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

USER POOL DEMO


• 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
