Roundtable on Serverless: Concepts, Value, Industry Practices, and Future Trends

The article summarizes the Serverless roundtable held at Techo TVP Developer Summit ServerlessDays China 2021, featuring experts from AWS, Alibaba Cloud, ByteDance, and Tencent Cloud.

Participants discuss the definition and value of Serverless, noting that overseas markets show higher adoption and larger-scale projects, while China lags due to lower cloud penetration and fragmented standards.

They stress the importance of standardization—comparable to S3 APIs—to ease migration and promote broader developer adoption, and advocate for deeper cloud‑native integration.

Case studies are presented: Alibaba reports up to 48% human‑resource cost reduction and significant machine‑cost savings during large‑scale promotions; ByteDance highlights its high‑QPS FaaS built on Kubernetes with microVM optimizations; Tencent describes multi‑cloud support and tight integration with the Serverless Framework for vendor‑agnostic deployments.

The discussion addresses technical challenges such as cold‑start mitigation, covering approaches like periodic warm‑up, provisioned concurrency, load‑balancer‑driven scaling, microVM performance improvements, and runtime optimizations.

Future directions explored include treating Serverless as a universal execution engine, tighter cloud‑native design, hybrid‑cloud architectures, convergence of microservices and FaaS, and anticipated trends over the next three to five years driven by ecosystem, tooling, and methodological advances.
