In order to provide a robust service with low cost of ownership, the SaaS product needed to easily leverage existing eComm services, require minimal setup and deployment across all mobile devices, and sit within a hosting architecture that is automated, scalable and affordable.
We designed serverless architecture in AWS using SAM and Cloud Formation (as well as Lambda, api gateway, Cloudwatch, Insights, Dynamodb, and Cloud front). This provides an automated, highly secure storefront hosting service for all business users which allows for instantaneous scaling and provisioning as end-user traffic grows, for a low cost. We designed the application templates as PWA’s to provide native-like user experiences simply across devices. The templates leverage drag and drop store building to create user-friendly mobile shopping experiences with swipe, tap, and pinch navigation and one-tap-buying. We configured a strong security model where: each lambda function can do only what it’s designed to do; The system detects ZIP files that are being uploaded and prevents malicious actions like infinitely recurring archives; Protection against DDOS attacks, with lots of logic, including limiting the number of actions that can take place concurrently; Throttling on lambda functions; Various custom logic; All deployment is fully automated and can be set up via APIs or command-line tools.
The new SaaS product was launched in May of 2021, with thousands of customers already online. Each PWA deployment was fully automated and set up via APIs or command line tools and took 15 minutes or less. Enthusiasm for the serverless architecture is spreading across the dozens of product lines developed by this global software company. The mobile storefronts project is expected to serve as a model for future migrations.
