Mobile first means API first strategy
API Gateway is a way to connect real world cloud ready applications with different IOT devices in the multi-platform world. New applications need to design data model and create public APIs to be consumed by mobile apps, third party apps and different devices. We will explore best practices, which you must adopt to be cloud mobile ready. Firstly, we will explore how contract first API development is helping enable more extensible and reliable APIs. Next, we will ask tough questions during this design session. How to provide security? What are best practices to authenticate? When should we version APIs? Should we use HATEOS for designing APIs? How to support internationalization? How to publish and maintain APIs? Mobile applications demands offline support, and geo-location application interfaces. We will explore best practices for scaling, securing, and proxying APIs.

About Rohit Bhardwaj
Rohit Bhardwaj is a Director of AI & Data Architecture at Salesforce, where he focuses on enterprise AI, agentic systems, cloud-native architecture, distributed systems, data platforms, security, and large-scale transformation.
Over his career, Rohit has designed and led complex enterprise platforms across AWS, Google Cloud, microservices, real-time data, API ecosystems, resilient distributed systems, and AI-enabled architectures. His work increasingly focuses on the challenges enterprises face as software evolves from deterministic services to AI-native and agentic systems—particularly around reliability, governance, evidence, security, observability, cost, and safe autonomy.
Rohit is the author of System Design with AI Interview Guide: Designing Scalable, Agentic, and Defensible Systems, published by Apress. The book presents a modern approach to system design covering scalability, distributed systems, AI architecture primitives, security, reliability, economics, agentic systems, and real-world architectures including e-commerce, ride sharing, payments, fraud detection, messaging, video streaming, file storage, and search.
