Sharing ByteDance's cloud-native technologies, technical practices, and developer events.
ByteDance engineer Li Benchao shares his ten‑month evolution from a curious newcomer to a PMC member of Apache Calcite, describing how his work on Flink SQL led to deep involvement in the open‑source community, technical growth, and mentorship.
This collection highlights ByteDance’s evolution in cloud‑native technologies, covering their microservice runtime architecture, large‑scale computing practices, open‑source project creation, and container scheduling advancements, providing links to detailed articles for readers to gain deeper insight.
KubeGateway, a custom seven‑layer gateway built by ByteDance, eliminates kube‑apiserver load‑imbalance and adds comprehensive request governance—including routing, rate‑limiting, and degradation—by parsing HTTP2 traffic, supporting flexible policies, and transparently proxying requests without client changes.
ByteDance’s Cloud Shuffle Service (CSS) replaces the traditional Pull‑Based Sort Shuffle in Spark, FlinkBatch and MapReduce with a Push‑Based remote shuffle that improves stability, performance and elasticity, supports compute‑storage separation, and delivers significant speedups in large‑scale TPC‑DS benchmarks.
This article explains ByteDance’s evolution from monolithic services to a multi‑runtime microservice architecture, introduces four sidecar runtime models, details the ByteRuntime design with Mesh Pilot and governance layers, and shares performance‑boosting techniques such as PGO while comparing ByteRuntime with DAPR.
As cloud computing becomes essential infrastructure, cloud‑native systems gain flexibility but face stability challenges, prompting China’s Academy of Information and Communications Technology to launch a 2022 chaos engineering survey that uncovers vulnerabilities and promotes practical adoption of reliability techniques across the industry.
This article explains the concept of cloud native, tracing its evolution from early cloud computing to CNCF's 2018 definition, and explores key technologies such as containers, Kubernetes, microservices, service mesh, immutable infrastructure, and declarative APIs, while also highlighting modern cloud‑native services.
KubeZoo, an open‑source lightweight multi‑tenant solution from ByteDance, uses protocol conversion to create virtual tenants on a single Kubernetes master, offering native API compatibility, low overhead, and a serverless‑ready foundation while addressing the challenges of multi‑tenant cluster management.
ByteDance announced the open‑source KubeWharf project, a cloud‑native suite built on Kubernetes that includes high‑performance metadata storage (KubeBrain), a seven‑layer API gateway (KubeGateway), and a lightweight multi‑tenant solution (KubeZoo), detailing their features, roadmap, and the drive toward large‑scale, multi‑tenant cluster management.
