The API Layer for use by mobile applications.

Problem statement: Business all over the world have found mobile computing contributing to the topline and driving sales as customers appreciate the ubiquity and convenience of services accessed via handheld devices. Regardless of the business model, purpose and value offerings, most mobile applications require certain minimum requirements from backend services. This article attempts to enumerate some such requirements. 

Solution: The primary language of communication between mobile applications and business services are web requests made over HTTP. Fortunately, web applications have been around for over several decades leveraging clean separation of concerns and adoption of standardized application blocks, protocols, and deployment strategies. Their evolution from onerous object relational mapping in monolithic application logic and storage has shown a shift towards decentralized application modules hosted as microservices in a deeply separated hardware and software stacks hosted in the cloud. They continue to evolve with improvements made in specific pockets, but we are writing this article to pay attention to the considerations that will significantly improve the most common mode of implementation and one that will support a growing business. 

• Cloud-empowered mobile applications: Even though large corporations are heavily invested in hybrid cloud computing; we recommend a public cloud infrastructure for attracting traffic to your business. It is a big sponge for the data that flows from customers and even with multi-tenant model on a highly efficient and cost-effective hybrid cloud computing framework, the future would be brighter with public cloud computing. Public cloud is here to stay and not just because Information technology was deprioritized to commodity computing in favor of new business processes and efficient business models. Build it right from the start. Sure, there might be some noise about cost estimates, changing landscapes and adoptions, and the insecurity about handing off your infrastructure to the cloud, but these diminish in favor of the overall value of the public cloud.
