FaaS in eCommerce: Is It Relevant?

[badsha00313]

According to Datadog's 2023 State of Serverless report, 70% of organizations using AWS already deploy Lambda functions as part of their cloud architecture, showing how widely adopted FaaS has become across industries.

While FaaS is ideal for small, modular workloads, it hasn’t yet been widely adopted for full-scale ecommerce platforms. That’s because ecommerce requires persistent state management, complex workflows, and high whatsapp lead levels of customization — challenges that aren’t easily addressed in a pure FaaS environment.

That said, FaaS can support ecommerce microservices like:

Dynamic price calculation
Order confirmation emails
Inventory updates
Image processing
Some composable and headless ecommerce platforms may use FaaS selectively for performance optimization, especially in JAMstack or MACH-based architectures.
