5G’s Impact on Cloud, Edge, and Reactive Programming: Highlights from Beijing’s Cloud+ Conference

The Cloud+ Community Developer Conference in Beijing focused on "5G Exploration: Core Technologies and Challenges," featuring speakers from Tencent Cloud, Tongcheng‑Yilong, and Beike Jinfu who discussed how 5G reshapes applications and infrastructure.

Yu Yifan – Tencent Future Network Lab: 5G Exploration and Practice

Yu explained that 5G is not merely a technical upgrade but introduces complex ecosystem issues, especially for B‑to‑B services where user demands differ significantly from 4G. He highlighted Tencent’s two‑year exploration in cloud‑based multimedia (cloud gaming, video streaming, video production), autonomous driving, and intelligent connectivity.

His summary of Tencent’s 5G ecosystem strategy covered four pillars: collaborative operation, open standards, joint R&D, and foundational research.

Li Zhihui – Tongcheng‑Yilong: Reactive Programming in Practice

Li described how high concurrency can crash systems when request volume exceeds container thread limits, a problem amplified in the 5G era. He introduced reactive programming as the mainstream solution, focusing on the Flower framework built atop Akka’s Actor model.

Key points included:

Flower leverages Akka Actors to eliminate latency and blocking between computations.

Flower simplifies Actor development compared to raw Akka usage.

Live demo showcased five‑minute onboarding, visual workflow orchestration, Spring‑compatible web development, asynchronous database access, and distributed micro‑service solutions.

Liao Long – Tencent Cloud: CDN Edge Intelligence for 5G

Liao argued that 2020 marks the commercial debut of 5G, with CDN and edge computing playing crucial roles in delivering high‑bandwidth, low‑latency services for the Internet of Things.

He explained that AI inference will shift from devices to cloud‑proximate data centers, offloading heavy computation to nearby edge nodes. To overcome traditional CDN latency, Tencent Cloud employs a dense network of small data centers and MEC (Multi‑Access Edge Computing) solutions, supplemented by the Volcano burst‑resource system to meet growing bandwidth demands.

Shi Haifeng – Beike Jinfu: From Beacon Towers to the Internet of Things

Shi presented a philosophical view, treating life as an information processor and communication as evolving from primitive signals to electric transmission. He questioned the necessity of ever‑higher resolutions (e.g., 20K video) beyond human perceptual limits and emphasized the need for practical IoT scenarios such as indoor navigation.

He concluded with speculative questions about the implications of universal connectivity on human boundaries and the possibility of a conscious network.

Roundtable Discussion: 5G’s Influence on Application Development

Panelists discussed the first user‑facing 5G scenarios (cloud‑media for C‑end, openness for B‑end), advised developers to maintain curiosity and insight, and stressed that active participation in 5G evolution is essential for understanding its technical impact.
