Serverless 2024: Key Trends, Best Practices, and Future Challenges Revealed

Conference Overview

The event, held on June 5, 2021 in Beijing, gathered over 500 on‑site developers and more than 90,000 online viewers. Organized by Tencent Cloud TVP and ServerlessDays, the summit’s theme was “Serverless, Empower More,” and it featured speakers from Tencent, AWS, Alibaba, ByteDance, and other leading cloud providers.

Market Outlook

Host Yang Weihua cited a KBV forecast that the global Serverless market will reach US$14 billion by 2024, growing at a 21.9% compound annual rate, underscoring the technology’s rapid adoption.

Conceptual Foundations

Lu Maozheng likened Serverless to the shift from cash to online payments, emphasizing that Serverless is not only a technical paradigm but also a lifestyle change for developers.

Product and Use‑Case Highlights

Zhang Hao presented Tencent Cloud Serverless products, illustrating applications in video streaming, IoT, online education (TRTC), and AI‑driven Dunhuang mural analysis. He also described the integration of Serverless with the SaaS platform Tencent Qianfan and announced the upcoming “Web Function” aimed at lowering the entry barrier for novice developers.

Service Governance

Chen Hao (MegaEase) addressed the governance challenges of massive micro‑service granularity in Serverless environments. He identified API, SLA, and service‑level agreements as three core pillars and offered Mesh‑based and SDK‑based solutions for effective service management.

Strategic Perspectives

Wang Xiaobo (CTO, Tongcheng‑eLong) argued that Serverless’s true value lies in accelerating monetization speed rather than merely cutting server costs. He demonstrated how Serverless can boost refactoring efficiency in rapidly evolving businesses.

Serverless + X Innovation

Speakers highlighted how Serverless combines with low‑code platforms, SaaS, and other cloud services to create more competitive products, breaking traditional development silos.

MicroVMM Technology

Fei Lianghong (AWS) explained the role of microVMMs, focusing on Firecracker as an open‑source project that provides secure, fast‑startup, high‑utilization environments for Serverless workloads. He forecast future optimizations such as Rust‑based VMs and unified hypervisors.

TDSQL‑C Serverless Database

Yang Jueji introduced TDSQL‑C, the first fully Serverless MySQL‑compatible cloud‑native database in China, featuring automatic scaling, pay‑per‑use billing, and suitability for startups seeking cost‑effective data services.

Function Mesh & Pulsar Functions

Zhai Jia (StreamNative) described Pulsar Functions as a lightweight, function‑as‑a‑service layer that enables event‑driven processing without deploying separate systems, simplifying operations for message‑and‑stream workloads.

Serverless in Microservices

Han Xin (Tencent Cloud Microservice Center) summarized five advantages of Serverless‑enabled microservices: business‑centric development, multi‑language support, simplified application building, portability, and observability, all of which reduce operational complexity.

Balancing Serverful and Serverless with EKS

Yu Guangyou (Tencent Cloud Container) compared IaaS, PaaS, CaaS, and FaaS, then introduced Elastic Kubernetes Service (EKS) as a solution that retains Kubernetes capabilities while lowering maintenance overhead, demonstrating its effectiveness in microservice migration, hybrid cloud, and big‑data container scenarios.

AI Inference on Serverless

Michael Yuan (Second State) showcased WasmEdge, a WebAssembly‑based runtime that lets developers deploy TensorFlow models on Tencent Cloud Serverless with only a few lines of code, offering a lightweight alternative to traditional AI SaaS.

Observability Practices

Gal Bashan (Epsagon) shared best practices for distributed tracing and monitoring in Serverless environments, drawing lessons from AWS Lambda and emphasizing the need to align technical observability with business value delivery.

Round‑Table Discussion

Leaders from AWS, Alibaba, ByteDance, and Tencent debated standardization, cold‑start mitigation, multi‑cloud support, and the long‑term evolution of Serverless. Consensus highlighted strong growth prospects over the next 3‑5 years and the importance of open‑source collaboration.

Conclusion

The summit delivered a comprehensive view of Serverless’s current state, emerging technologies, and future directions, reinforcing its role as a pivotal cloud‑computing paradigm and setting the stage for continued community‑driven innovation.
